Is Cloud Computing the Game Changer Your
Company Needs in These Tough Times?

There have been countless articles written about cloud computing; a Google search will
return millions of hits. Your colleagues discuss it at lunch and vendors bring it up in their
presentations. From the enterprise perspective, it could be the perfect storm of value
propositions—cloud computing drives the cost of IT down, is available on demand, and is
scaleable. Cloud computing could even become a new competitive edge for your company.
Maturing at a rapid pace, it will be the next chapter in data processing. But is it ready for your
company? Can the hype of cloud computing live up to its promise?

I call cloud computing a “game changer” because it is a service, a platform and operating
environment poised to transform the status-quo computing model. Advocates argue it will

Customized Tool for Automated Storage
Provisioning

Homegrown tools for storage provisioning automation can improve efficiency and implement
a common standard in a multi-vendor storage environment. This enables teams to work more
efficiently and eliminates the need for expensive SRM tools that may not meet all business
requirements. In the current economic environment, this is even more important as groups
are being downsized and budgets cut while storage capacity and fiber switch ports increase
at a breakneck speed.

In 2009, we provisioned 6.0 PB of enterprise-class SAN-based storage, compared to 4.3 pro-
visioned in 2007, a year-to-year increase of 140 percent. Our current environment is growing
at a rate of ~100 TB per week. SRM tools do not scale to meet our requirements and service
level agreements (SLAs) with this growth rate. Using our custom implementation, we can
provision ~50 TB of storage across multiple frames in less than one hour and reduce overall
re-work and human error. This includes design validation, LUN creation/masking, and zoning.

This article discusses how to use vendor-provided CLI software to create/implement custom-
ized provisioning tools. SRM-based provisioning tools are great for organizations with small
storage footprints. However, they do not scale in larger and more diverse, enterprise-class,
multi-data-center environments due to implementation costs and increased total cost of
ownership (TCO).

Instead, we can implement a customized provisioning solution with a small data center foot-
print and very little additional cost to the company. This article discusses how to implement
end-to-end storage provisioning automation using multi-vendor storage/switch platforms.
The process includes a centralized ticketing system to track the storage request throughout
its lifecycle. This enables the overall storage automation process. The workflow tool tracks
approvals and design information, providing the feed to the automation scripts and informa-
tion to the system administrator to build the file systems based on the design.

Due to central automation, we can guarantee standards across multiple data centers/envi-
ronments and easily create standard reports.


Reclaiming SAN Storage—The Good, the
Bad, and the Ugly

“My bonus is based on saving $5M worth of storage.”

“We are cutting the storage budget so you need to reuse capacity.”

“We cannot purchase additional storage until we increase utilization.”

Reclaiming storage capacity for reuse reduces IT capital expenditures, increases storage
utilization, contributes to “green computing” initiatives, and can address each of the issues

Architecting an Enterprise-Wide Document
Management Platform
Jacob Willig, Documentum Consultant

This article presents best practices discovered while implementing EMC Documentum® within
large organizations using a central-platform approach. Documentum is typically implemented
as a dedicated host for document management and storage. The implementation is tailored
to the specific set of functional requirements and does not necessarily consider future expan-
sion into different functional areas across the organization. If the need arises, a new point
solution is often implemented. It, too, is tailored to the new and existing requirements.

This approach fulfills the short-term business need for functionality, but it becomes increas-

Real-Life Application of Disaster Recovery
Faisal Choudry, Magirus UK Ltd.

EMC business continuity (BC) and disaster recovery (DR) offer a myriad of options to protect
your data. Organizations sometimes implement them without a thorough analysis of how
and when they would use the technologies to recover data if needed. Even if familiar with the
technology, procedures can be so arduous that the organization has no chance of meeting
their committed recovery point objective (RPO) and recovery time objective (RTO). “State-of-
the-art” recovery technologies cannot help if no one knows how to use them.

Organizations need procedures to document how to implement their recovery technologies.
This is even more important if an external organization did the implementation. What ques-
tions should you consider?

• hen the implementation ends, can the customer grasp the complexities of the new
W
technologies and use them if needed?
• Can we make these complex solutions easier, especially when organizations don’t

have the “luxury” of appointing a full-time disaster recovery team?

SMEs and technology professionals face these issues when proposing BC and DR solutions.
This article uses a case scenario to examine these questions in relation to a recent real-life
solution, one that I proposed and implemented. The solution included multiple sites, using
EMC CLARiiON® systems (CX3-10 systems) at each site, EMC MirrorView™/Asynchronous,
and EMC SnapView™. ESX™ Servers are the attached hosts, so we implemented Site Recov-
ery Manager (SRM) using the recently released SRA adapter for MirrorView/A.

The project was successful, but raised interesting afterthoughts, especially regarding end-
users’ perceptions and technology expectations. In conclusion, this article will offer advice
on how to address these issues.

Best Practices for Implementing and
Administering EMC NetWorker
Anuj Sharma, Ace Data Devices

EMC NetWorker® is the fastest performing backup application in the market. Integration with
replication and snapshot technologies helps you meet the most aggressive RTO and RPO
requirements and transform backup to disk or backup to tape in an off-host, off-hours process.
It supports a broad set of operating systems, databases, applications, and topologies.

EMC NetWorker’s compatibility with various operating systems, applications, and databases
makes it successful in today’s competitive industry. However, it must be implemented properly
to get the most out this wonderful product. There are some practices to keep in mind to make
the backups and recovery more effective and beneficial for the organization.

This article covers the various practices that I performed when implementing and administering
EMC NetWorker. They include:

• Implementing NetWorker on various operating systems
• Making it foolproof in case of NetWorker server disaster
• mplementing NetWorker in a bidirectional as well as unidirectional hardware
I
firewall, including various scenarios (i.e., when some of the clients are in DMZ)
• Working with the NetWorker ports
• Implementing NetWorker in a cluster
• Integrating e-mail alerts with NetWorker
• Implementing persistent binding through EMC NetWorker
• Integrating EMC Avamar® for deduplication
• Probe-based backups


A Load-Balancing Algorithm for Deploying
Backup Media Servers
Krasimir Miloshev, EMC Corporation

Finding the best backup client’s distribution over designated media servers can be considered
part of the general load-balancing problem. Our goal is to distribute the backup client’s data
in the best possible way among newly designated media servers responsible for the backup
read/write operations.

This article suggests a load-balancing approach based on one criterion—the amount of
data that must be backed up on each client. It begins by introducing the basic components
of backup infrastructures: the master server, clients, media servers, and storage backup
devices. It presents two approaches for deploying media servers and provides a structure for
decision making.

Next, we investigate a load-balancing schema where there are only 10 media backup clients
and two media servers. We calculate capacity and learn a load-distribution algorithm. Finally,
the article aligns the basic load-balancing algorithm to program implementation. In two easy
steps, you’ll be able to implement the algorithm using C or Korn-shell.

We can reduce the backup window by balancing the backup load among all the backup media
servers. Even when data size is the only criteria we use, we can expect to achieve visible
performance improvement and shorter backup windows.

Backing Up Applications with NetWorker Modules
Aaron Kleinsmith, EMC Corporation

This article describes how to configure EMC NetWorker® to back up a database application.
It includes NetWorker’s technical setup to help protect popular databases that relate to
released NetWorker modules. Backup administrators who configure and monitor the online
database backups through NetWorker benefit most from this article.

The article discusses traditional database backup methodologies such as online (hot) back-
ups, offline (cold) backups, and transaction log backups. The article describes the backup
procedure to capture a consistent copy of an online database and transactions logs from
the source disks using the application server resources that manage the primary copy of the
database and data.

It provides enough technical information to help a storage administrator who manages
NetWorker verify and monitor a properly set-up client.

This article discusses:

• Overview and explanation of NetWorker modules
• General concepts and planning applicable to all NetWorker modules
• etWorker configuration settings applicable to all modules and specific settings

Implementing Deduplicated Oracle Backups
with NetWorker Module for Oracle
Chris Mavromatis, EMC Corporation

More and more customers are now evaluating the cost benefits of data deduplication. This is
partly due to the explosive growth of software deduplication technology (such as EMC Avamar®).

EMC NetWorker® Module for Oracle is a mature product, with thousands of customers, that
offers a strong backup solution for an Oracle database. The first quarter of 2009 will be the
first time that NetWorker Module for Oracle will have deduplication integration for Avamar.
This feature empowers users to conduct Oracle deduplication backups and restores via the
integrated use of a deduplication storage node (Avamar server). A deduplication backup
can be a manual backup initiated within RMAN or a scheduled backup via the NetWorker
Management Console scheduler framework.

There are a number of differences and additional configuration items that we must consider
when deploying NetWorker Module for Oracle 5.0 to perform deduplication backups. This
article outlines installation, configuration, pitfalls, and best practices. It provides answers to
questions that can help customers better embrace this paradigm shift in backup solutions.

This article highlights these considerations and provides guidance for deployment. It is not
intended to be a step-by-step guide, nor does it replace the Installation Guide or Release
Notes. It does assume a level of knowledge using NetWorker, Avamar, Oracle, and NetWorker
Module for Oracle.

Sales, systems engineers, support personnel, and customers will benefit from learning how
to deploy this solution.


NDMP Localization/Internationalization
Support for NetWorker
Jyothi Deranna, EMC Corporation

Computer internationalization and localization are important because of the numerous
differences that exist among countries, regions, and cultures with respect to language (not
only distinct languages but also dialects and other differences within a single language for
weights and measures, currency, date and time formats, and more).

The EMC NetWorker® NDMP client-connection feature provides NAS with fast, flexible backup
and restore of mission-critical data residing on filers. The Network Data Management Protocol
(NDMP) is a TCP/IP-based protocol that specifies how network components communicate
with one another to move data across the network for backup and recovery. NetWorker with
NDMP client connections provides backup and recovery support for more than eight NAS
hardware providers. With NetWorker 7.4, the NDMP client is responsible to back up and
recover the non-ASCII data from the NAS filers.

EMC NetWorker 7.4 is a full-fledged internationalization release; the product is I18N and
L10N compatible. Many changes were made in the NDMP client-connection feature to handle
non-ASCII characters. NAS vendors each have their own mechanisms to store the non-ASCII
characters in their specific filers. NDMP is a single interface that helps NetWorker understand
how each vendor is handling non-ASCII data. Using NDMP, NetWorker is able to back up filers’
data and store it without data corruption.

This article explains how NetWorker backs up and recovers non-ASCII data residing in the NAS
filers using the NDMP client-connection feature. It describes how to configure NAS filers for
non-ASCII data backup/recovery and explains how the changes are done while configuring a
NAS filer as an NDMP client. It offers guidelines to configure filers from different vendors and
best practices and troubleshooting tips to avoid data corruption and increase performance.

Using Disks in Backup Environments and Virtual
Tape Library (VTL) Implementation Models
Emin Calikli, Gantek Technologies

Protecting data is vital for availability and business continuity. There are many data protection
solutions in the IT market. However, they address recovery time objectives (RTO) and recovery
point objectives (RPO). Recovery time represents the time it takes to restore the data; recovery
point represents the “data currency” at the backup state. These two concepts are not indepen-
dent and must be integrated based on company requirements.

Many organizations are experiencing shrinking backup windows and increasing data loads.
During a restore from tape, slower recovery operations result in longer production system
downtime. Companies are seeking faster backup and recovery solutions.

“ used current, real-world data
I Disks could be a viable solution for meeting fast data recovery requirements. The service
protection requirements and personal level agreement (SLA) depends on the application and the customer. It is often difficult

Enterprise Standards and Automation for Storage
Integration and Installation at Microsoft
Aaron Baldie, EMC Corporation

Microsoft’s most challenging problem is how to keep tens of thousands of servers up to date
with drivers and firmware in an environment that is spread across many global data centers.
More and more, these data centers are subject to budget and staff cuts. Personnel are
becoming less specialized, and in some cases, have no technical training at all other than
the ability to power cycle equipment.

The EMC account team has worked directly with Microsoft’s IT staff to overcome these
challenges and provide standards for drivers, firmware, and complete automation packages
that integrate with existing processes to allow for storage connectivity across the enterprise.
This allows Microsoft IT staff to rapidly deploy EMC storage to any server globally and manage
this storage with a limited, centralized IT staff.

To accomplish this, the EMC Support Matrix is refreshed on a six-month cycle to provide a
baseline of supported drivers, firmware, and applications, and their compatibility with the
OS and hardware. A matrix is published to lock in the revisions so a deployment kit can be
created once this standard is established.

All drivers are then downloaded to a central location and rolled into an automation package
that can be integrated into Microsoft’s own deployment process. Testing is performed for
multiple scenarios across all currently supported OS versions for both upgrades from the
existing standards and new deployments. Any issues found during this test process are
triaged with Microsoft and fixed before the latest versions are released to gold. The local
account team accomplishes all of these tasks and owns the project from start to finish.

EMC and Microsoft’s strong alignment and rapid deployment of EMC hardware achieves one
of the largest ratios of storage to administrator at about 1.5 PB per head count across 150
EMC CLARiiON® systems and 10 EMC Symmetrix® DMX™ systems.

Significant Savings are Within Your Reach when
You Understand the True Cost of Storage

Do you find yourself struggling with your company’s insatiable craving for more storage? Will
any of your storage suppliers’ claims of “faster, cheaper, and better” really save your company
money? How about the stark reality that your dwindling IT budget is causing you sleepless
nights? Has the time come to expand the outdated, state-of-the-art storage infrastructure you
leased just three years ago?

You may be asked to trim capital and operating storage expenses by hundreds of thousands
of dollars, while simultaneously introducing innovation to your organization. This seemingly
contradictory set of storage demands also impacts your internal service level agreements.
Where do you begin? Which concepts will deliver significant short- and long-term savings?

yesterday. In addition, corporate policies and regulations require us to save that data for
longer periods of time. That means storage, which translates into more floor space, more
power, more staff, and more complexity.

This article explores the challenges facing the IT storage manager and offers insight into
navigating a course of action to provide budget relief, while offering better services to
internal and external customers. It explores issues such as frame expansion and future-proof
architectures, environmental impact, virtualization, deduplication, risk avoidance, stretch-

and operate an efficient, green data center. This discussion occurs in the context of a
virtualization-leveraged data center.

Virtualization has been positioned as the core enabler for driving broader efficiencies. It
includes server and storage procurement and utilization, information protection (backup and
recovery), business continuity and disaster recovery (local and remote replication), infrastruc-
ture management, and infrastructure consolidation and automation. This article provides
you with a breadth of knowledge about the major data center functions that have a direct or
indirect impact on operational and environmental efficiency.

Our discussion is not limited to technology, but includes other relevant areas of a data center
that are either impacted by or have an impact on the technology infrastructure and IT opera-
tions. It identifies major areas of consideration as well as step-by-step guidance about how
to implement power and cooling, virtualization, and other related technologies. Designs and
architectural drawings for optimization are included.

This article consists of three sections:

• ntroduction focuses on financial and environmental impacts of inefficient data

centers and the case for building efficient and green data centers.
• Considerations for Building Efficient, Green Data Centers focuses on high-level data

center operating environments, IT processes, and technology considerations for data
center efficiency.
• Implementing an Efficient, Green Data Center focuses on implementation processes,

steps, and technologies; and describes designs and architectural drawing in detail.

Best Practices for Deploying Celerra NAS
Ron Nicholl, A Large IT Division

Deploying EMC Celerra® NAS involves many pieces of the IT infrastructure ranging from
backend storage, to network topology, and beyond. Choosing a solid design can make the
difference between mediocre performance and exceeding your customers’ expectations.

NAS solutions are quickly becoming a viable alternative to mitigate the cost of a SAN-based
storage solution. A Celerra NAS solution offers much of the same functionality traditionally
seen on the storage array over IP, including replication, checkpoints, mirroring, and more.
Applying best practices to your design will improve performance and reliability.

CLARiiON and FCiP: A Practical Intercontinental
DR and HA Solution
Jaison K. Jose, EMC Corporation

EMC CLARiiON® offers possibilities that meet almost all the needs of today’s high-demand
business. We can easily achieve complex industry requirements when we join this small
magic box to other technology. I would like to share an Intercontinental disaster recovery (DR)
solution that was achieved with the help of several products, including EMC CLARiiON,
MirrorView™/AS, SnapView® Clones, SnapView SnapShots, FCiP, and Vsan.

We had to find a solution to implement a primary site in Europe and a disaster recovery site
in the U.S. for a customer-facing application of EMC, so it was very important to have a robust
solution with a proper DR plan. FCiP was our first choice to manage data movement flawlessly
over the Atlantic; we could use Internet connectivity and VPN to create a tunnel between the
two sites. We segregated the data replication SAN by separating the ports to a special VSAN
extending to the DR site using FCiP.

CLARiiON was the obvious choice for this midrange application. The amount of data was
huge, but it was not very dynamic. Data availability was the primary concern. How would we
connect two sites separated by thousands of miles with a CLARiiON? Our best answer was
with MirrorView/AS since the data is sent through the FCiP tunnel to the DR CLARiiON.

Then, we needed a backup solution. This environment was hosted in a third-party data
hosting facility. A tape-based or external backup option often costs more money. SnapView
Clones were our answer. A gold copy of production and DR LUNs were set up to protect
against data corruption or data loss caused by human error.

MirrorView A/S, SnapView SnapShots, SnapView Clones, FCiP, and Vsan—all of these
products’ features are utilized in this unique disaster recovery solution. This not just a
concept; it has been implemented and is working in a production environment. I am happy
to share it with you.

Oracle Performance Hit | a SAN Analysis
Kofi Ampofo Boadi, JM Family, Inc.

Performance problems can be avoided or minimized if we design the right disk layout. RAID
type definitions for specific components are essential to Oracle’s performance. Not keeping
defined components on the same spindles is equally crucial. This article uses a real-life case
study to explain Oracle’s components and illustrate the effects of a poorly designed SAN on
Oracle’s performance. A hit!

Please be aware that the order of the analysis is irrelevant; it is the content that matters.
Applications’ performance relies heavily on the SAN. Performance issues can be centric to
the host, connectivity device, or the storage array, or a combination. This article elaborates
on the effect that the SAN can have on Oracle’s performance with an emphasis on the EMC
CLARiiON® storage array. I will touch briefly on the Symmetrix since most of the concepts
and analysis in the article apply to the EMC Symmetrix® as well. The items below will be
addressed in detail via a case study.

1. Define and analyze sequential and random writes and how they impact Oracle’s

performance design.
2. Define the components of Oracle architecture and their importance.
3. What are Redo Groups and why are they important to Oracle’s performance?
4. Detail each component’s behavior on the SAN and which disk layout best fits for

optimal performance.
5. CLARiiON has a limited performance-tuning ability, it has a non-scalable cache,

hence which architectural designs do you need to avoid?
6. How host-side analysis and hit can contribute to the performance of Oracle.
7. witch-level specifications and alerts that can significantly contribute to the
S
performance of applications.
8. he Case study! This details most of the issues administrators run into and suggests

the best resolutions.

Performance analysis can be approached in several ways. The key is to use the appropriate
performance tools to understand what you are analyzing. Please note that different approach-
es may lead to the same result.


Preventative Monitoring in the NAS Environment
Robert Wittig, EDS an HP Company

The EMC Celerra® actively monitors the environment for warnings and failures. As the NAS
environment expands, it becomes increasingly important to assess the current health of each
frame and verify that the current configuration fully utilizes redundant Celerra capabilities.
Verification, testing, and preventative monitoring are important aspects of maintaining the
Celerra’s reliability and availability.

Once configured, we must test and monitor the Celerra environment to verify that it will prop-
erly handle any faults and continue to provide the services for which it was designed. Testing
should not stop once the system is in production; it should continue at regular intervals
to ensure continuous functioning if a failure occurs, and to notify the appropriate support
personnel in the event of a failure. Finally, we should make non-intrusive checks at regular
intervals to verify that regular support activities have not adversely impacted any part of the
environment.

This article identifies methods and preventative measures to identify configuration issues,
verify redundant hardware, and ensure that configured notifications function properly. The
objective is to provide the Celerra storage administrator with a set of actions to check the
status of a running environment, verify redundant operations, validate the configuration, and
confirm that failure notifications are functioning properly.

We will examine four parts of the Celerra environment:

• Provisioned storage
• Redundant data mover configuration
• Warning and failure notifications
• Celerra Connect Home functionality

Finally, this article suggests methods that can be applied to gather these checks into a
single automatic process. This process can be regularly executed to provide evidence of the
validated configuration and identify potential problems before they impact the availability
of the services or of the entire Celerra.

Create a Comparative Analysis of an Oracle Database
Using Storage Architectures NAS and SAN
Volnys Borges Bernal, Universidade de São Paulo/LSITec

Today’s storage architecture market is divided among three large groups: direct-attached
storage (DAS), network-attached storage (NAS), and storage area network (SAN). The stor-
age system, among others, affects any application’s performance. The application’s overall
performance is also affected by the storage network technology, the data storage commu-
nication protocol, and the storage network components. Performance is measured using
response time.

Storage managers have difficulty aligning the application’s needs to the appropriate storage
architecture. Many factors are involved in this decision, including the compatibility between
the host bus adapter, switches, and storage systems, and the latency, cost, and management

Custom Documentum Application Code Review
Christopher Harper, EMC Corporation

An EMC Documentum® consultant typically is the last point of contact when things have gone
wrong. Firefighting is the term given for this type of corrective work.

These assignments are caused by solutions that are developed by someone with limited
knowledge of our systems. This lack of knowledge causes issues both in the design of the
application and the way it is implemented. This daunting task typically presents itself as
heaps of documentation, one or more DFC/WDK projects containing source code, and a
time-boxed schedule that prevents a full review of documentation and code.

How should we approach reviewing code written by a third party who doesn’t necessarily
conform to the standards you are accustomed to?

This article provides basic principles on what to look for and explains some of the common
ways that our systems are misused leading to poor performance. I will provide the technical
rationale for each instance where we discuss why or why not to use a particular approach.
Also, we will discuss corrective measures for each encountered problem. I will present the
technical solutions for all of the cases we discuss. The cases are ‘real’ and have been
encountered “in the wild.”

Data Migration Strategy (SRDF via “Swing Frame”)

Increasing data center power and cooling requirements impact IT infrastructures’ scalability.
Storage consolidation provides relief for power and cooling and also reduces total cost of
ownership (TCO). Simplifying storage infrastructures and ease of management are the two
reasons that businesses use storage consolidation. Businesses have had to scale their stor-
age infrastructures to accommodate capacity, performance, and high-availability require-
ments due to massive data growth.

This article provides guidelines for using storage-based replication (EMC SRDF®) to migrate/
consolidate data from multiple storage arrays to just a few. It explains how to migrate data
using SRDF from (5670) to (5772) code using a swing frame method (EMC Symmetrix®
DMX™-2) running (5671) code. This migration also involved multiple Oracle databases, so
maintaining data consistency was critical.

We were able to accomplish this task in a very short amount of time. There are advantages
and disadvantages of using storage-based or host-based migration methods. The article
discusses these and provides guidelines for migrating data from DMX-2 and DMX-3 arrays to
DMX-4 using SRDF.

Data Storage Performance—Equating Supply
and Demand

Individual components, including storage, contribute to the cumulative outcome of
performance. When the storage processing duration is proportionately long, “demand” is
the workload generated by host computer systems, and “supply” is the processing service
provided by the data storage system. The “quality of performance” experienced by the
business relies on how well supply meets demand.

We must match projected demand with capability to supply for selecting and designing
data storage components. The resulting solution would operate at an optimum level, where
demand equals supply. In this article, we apply the demand-supply analogy to build a
universal framework using data storage domain performance characteristics as proxies

Integrating Linux and Linux-based Storage
Management Software with RAID System-
Based Replication
Diedrich Ehlerding, Fujitsu Technology Solutions

All major database and ERP software vendors release their products on Linux. As with other
operating systems, we must replicate using RAID array functionality to meet the demands for
short backup windows, fast restore processes, and fast system copy processes. The legacy
device names that are traditionally used in Linux without any storage management software
are inappropriate for enterprise-class configurations. The main problem is that these name
spaces are not persistent over server reboots. They cannot guarantee that the system will find
its data at the same device node which it saw before the reboot.

This article discusses various naming spaces within Linux—legacy names, device mapper
names, IO multipathing software names, volume management layers, and file system layers.

Simplifying/Demystifying EMC’s TimeFinder
Integration with Oracle Flashback
Robert Mosco Jr., EMC Corporation

Integrating EMC TimeFinder® business continuity application with Oracle can be a somewhat
tricky endeavor. This article describes Oracle’s Flashback and EMC TimeFinder technologies
and how the two applications can help end users recover data.

Oracle Flashback and EMC TimeFinder are two separate technology applications. Under-
standing them, and then describing their integration for the purpose of recovering data, is
the main goal of this article. I use diagrams and commands to show how both technologies
can recover data. Once you have an understanding of each technology, the article progresses
to an integration phase showing how the two applications can be used to develop a “repair”
and/or a “recovery” plan.

Discussions include point-in-time recovery, Flashback rewind, and recovery time objectives.
The article presents the following:

• Enabling and disabling Oracle Flashback
• Setting up a TimeFinder Oracle business continuity (BC) environment
• Dropping and/or deleting data (to simulate a data corruption situation)
• Recovering or flashing back to a previous point in time
• Developing a recovery or a get-well plan

All of these topics include diagrams and commands with simple explanations to help you
understand the power of both technologies.


Service-Oriented Architecture (SOA) and
Enterprise Architecture (EA)
Charanya Hariharan, Pennsylvania State University
Dr. Brian Cameron, Pennsylvania State University

Most companies are re-evaluating the way they purchase, deploy, manage, and use business
applications due to challenging market conditions, competitive pressures, and new tech-
nologies. Software buyers want applications that leverage existing investments; customers
demand solutions that provide quantifiable performance improvement.

In response, companies must evolve into agile enterprises that can rapidly change direction.
Yet their structures, processes, and systems are often inflexible, rendering them incapable of
rapid change. Adding hardware, software, packages, staff, or outsourcing are not solutions.
This is not a computer problem, it is a business problem.

To address this growing gap between IT and business, companies are adopting an end-to-end
enterprise architecture approach to re-align IT development with business objectives. EA is a
framework that covers all the dimensions of IT architecture for the enterprise; SOA provides
an architectural strategy that uses the concept of “services” as the underlining business-IT
alignment entity.

These forces drive the IT industry to deliver breakthrough technologies, many at the founda-
tion layer. SOAs, specifically, are at the cusp of change. This article focuses on the relation-
ship between EA and SOA and the resulting impact on business. These are the key research
questions in this research:

• Are there any business impacts to marrying EA and SOA?
• How do organizations fit SOA with EA?
• Is it better to adopt either SOA or EA, and not both?

SRDF/Star Software Uses and Best Practices
Bill Chilton, EMC Corporation

Disaster recovery is becoming more critical as new laws are being passed to protect data,
and legislation mandates extended data-retention policies. Many companies are building
redundant data centers to avoid potential losses. The largest financial institutions are build-
ing three data centers, two located in close proximity with the other in a different region of
the country or in a different country altogether. These companies are managing three data
centers and keeping all the information consistent by deploying EMC SRDF®/Star software.

SRDF/Star is data-replication software that uses synchronous and asynchronous data trans-
fer to maintain consistency in multiple sites. The intent is to provide redundancy so that if
one of the data centers experiences a disaster, the other sites can continue to replicate data
and take over processing immediately. Star is exceptional as a disaster recovery software
program, but what else can you realize with this software and what are the best ways to
deploy it?

The documentation on SRDF/Star explains how the software works and how to install it, but
does not discuss best practices. This article seeks to bridge the gap between installation and
deployment by reviewing:

• Building a test Star
• Load balancing applications across data centers
• Eliminating downtime while working on servers
• Migrating data while staying consistent
• Switching between concurrent and cascading, and back again
• Best practices and troubleshooting hints


Using EMC ControlCenter File Level
Reporting for CIFS Shares
Chad DeMatteis, EMC Corporation
Michael Horvath, Fifth Third Bancorp

It can be a daunting task to gather file and folder statistics and properties from a NAS CIFS
share with deep directory trees. It is especially difficult when you’re using Microsoft Windows
native tools that may have poor enumeration performance. These activities consume a great
deal of time in an environment with tens of thousands of folders and millions of files.

This article discusses how EMC ControlCenter® Network File System Assisted Discovery
feature, introduced in v6.0, can be used to provide EMC Celerra® CIFS administrators with
file- and folder-level reporting, covering UNC FLR configuration considerations and lessons
learned during an EMC ControlCenter deployment. It provides practical examples of how you
can use CIFS FLR reports to quickly determine file age and type distribution, top storage users,
and utilization trending. These reports provide administrators with information to maximize
storage utilization and address CIFS storage consumption issues before they impact end users.

The article addresses the following topics:

Cloud Computing Services—A New Approach
to Naming Conventions
Laurence A. Huetteman, Technology Business Consultant

It has become increasingly difficult to have meaningful discussions about cloud computing
without a common language. You will see every inconsistency in naming conventions for
cloud technology when searching the topic on the Web; this inconsistency is also present
during consulting or business conversations.

Wikipedia defines cloud computing by using a six-layer stack of components with terms like
client, application, services, platform, etc., with the word “cloud” preceding each component.
Others refer to everything as a service, while others try to map SOA, utility computing, and
grid to cloud computing services. Even EMC’s suite of cloud computing offerings, while
technically impressive, seems to be a loosely coupled group of point solutions with no real
structure or clear naming conventions (Hulk/Maui evolved into Atmos™, Mozy™, Pi, etc.)
that are referred to generically as cloud computing.

Vendors, partners, and customers spend valuable cycles deciding which model to follow
in their discussions, or worse, inventing their own. My article simplifies this process and
applies logic to inconsistent naming conventions by proposing a new naming convention
for cloud computing service offerings. It is easily understood and applied across the broad
spectrum of services. It is intuitive, so it can be easily adopted, and based on a logical
model. If successful, this model will be flexible enough to accommodate the anticipated
growth of this evolving field of technology.

One consistent theme in all cloud computing discussions is the concept of tiering or layers
of services. The thought here is to use an existing scientific classification and to map the
layers to current and potentially future cloud computing components or services. One logical
choice is to leverage the familiar and widely accepted term, cloud, but map the model to
the common atmospheric cloud terminology. This article presents such a model to help you
effectively engage with other IT professionals.
