x IBM Information Archive: Architecture and Deployment

Preface

This IBM® Redbooks® publication can help you understand, configure, monitor, and use IBM
Information Archive.

As you address your information retention needs, whether keeping valuable content for long
periods of time, meeting industry retention regulations, or addressing corporate governance,
you need an archiving solution that is secure, scalable, but also cost-effective.

IBM Information Archive is the next-generation information retention solution designed as a
universal archiving repository for all types of content to help midsize and enterprise clients
reduce cost, manage risk, and address clients’ complete information retention needs:
business, legal, or regulatory.

This highly versatile, smart business system can be a useful tool for clients in their efforts to
support regulatory compliance by providing a storage repository with robust security features
designed to prevent the alteration or deletion of the storage repository in which information is
stored until their business-designated retention period has elapsed.

This book is a comprehensive document intended for customers and field personnel who
want to understand, deploy, use, and monitor IBM Information Archive.

Chapter 1. Introduction to archiving
In this chapter we introduce the concept of archiving and its business requirements. We
explain the need for retention managed data and briefly present the IBM Smart Archive
Strategy.

This strategy can help you realize the business value of your information while driving down
costs and risks as well as ensuring that critical business content is properly retained and
protected.

As an element of the IBM Smart Archive Strategy, we highlight the features of the IBM
Information Archive (Information Archive) and position them in this context.

© Copyright IBM Corp. 2010. All rights reserved. 1

1.1 The business need for archiving
Information or data is essential to any business and for the most part can be considered a
company asset. Examples of such data include contracts, CAD/CAM designs, aircraft build
and maintenance records, and email, including attachments, instant messaging, insurance
claim processing, presentations, transaction logs, web content, user manuals, training
material, digitized information (such as check images, medical images, historical documents,
and photographs), and much more. With that understanding, companies see a potential value
in aggregating large amounts of data.

In addition to the sheer growth of data, the laws and regulations governing the storage and
secure retention of business and client information are increasingly becoming part of the
business landscape, making data retention a major challenge to any institution. Regulated
information can include email, instant messages, business transactions, accounting records,
contracts, or insurance claims processing, all of which might need to be retained for varying
periods of time. Some of this data might be kept several years. Some data might also be kept
forever.

Moreover, some data must be kept just long enough and not any longer. Indeed, content is an
asset when it needs to be kept; however, if kept past its mandated retention period, it can also
become a liability. Furthermore, the retention period can change due to factors such as
litigation.

The characteristics of archived data can vary greatly in their representation, size, and industry
segment. It becomes apparent that the most important attribute of this kind of data is that it
needs to be retained and managed, so it is called retention-managed data.

Retention-managed data is data that is written once and is read rarely (sometimes never).
Other terms abound to describe this type of data, such as reference data, archive data,
content data, or other terms implying that the data cannot be altered.

Retention-managed data is data that needs to be kept (retained) for a specific (or unspecified)
period of time, usually years.

Retention-managed data applies to many types of data and formats across all industries.
The file sizes can be small or large, but the volume of data tends to be large (multi-terabyte to
petabyte). It is information that might be considered of high value to an organization,
therefore, it is retained near-line for fast access. It is typically read infrequently and thus can
be stored on economical disk media such as SATA disks. Depending on its nature, it can be
migrated to tape after some period.

It is also important to recognize what does not qualify as retention-managed data. It is not the
data that changes regularly, known as transaction data (account balance, inventory status,
and orders today, for example). It is not the data that is used and updated every business
cycle (usually daily), or the backup copy of this data. The data mentioned here changes
regularly, and the copies used for backup and disaster recovery are there for exactly those
purposes, meaning backup and disaster recovery. They are there so that you can restore data
that was deleted or destroyed, whether by accident, a natural or human-made disaster, or
intentionally.

All these factors mandate tight coordination and a controlled, intelligent approach to
archiving. This is what the IBM Smart Archive Strategy is aimed at.

2 IBM Information Archive: Architecture and Deployment

1.2 IBM Smart Archive Strategy
The IBM Smart Archive Strategy is a comprehensive cross-brand approach that combines
IBM software, systems, and service capabilities designed to help customers extract value and
gain new intelligence from information by collecting, organizing, analyzing, and leveraging
that information. This approach, depicted in Figure 1-1, delivers a comprehensive set of
solutions, products, and services in a unified and integrated strategy that helps you realize
the business value of your information while driving down costs and risks and ensuring that
critical business content is properly retained and protected.

With the IBM Smart Archive Strategy, you can simplify the archiving infrastructure and reduce
overall storage and power needs as well as administrative requirements with the help of
integrated appliances and multiple delivery options. Implementing an IBM Smart Archive
solution can eliminate unnecessary junk content, helping to improve system and process
efficiency and productivity. Reducing discovery costs and legal fees are key objectives, as
well as enhancing response capabilities by providing authorized legal staff quick access to
and analysis of case-relevant information.


Figure 1-1 The IBM Smart Archive Strategy

The IBM Smart Archive Strategy offers the following capabilities:
Optimized and unified ingestion:
– Enables a deeper understanding of what information to archive through
discovery-based and analytics-based assessment technologies.
– Eliminates point solution complexity and cost by unifying data and content archiving
through common collection (ingest) and classification technologies.
The following examples from the IBM Product portfolio fit that category:
– IBM InfoSphere™ Content Assessment software

software.
The following examples from the IBM product portfolio fit that category:
– IBM InfoSphere Enterprise Records software
– IBM InfoSphere Discovery Manager and Discovery Analyzer software

1.3 Introducing IBM Information Archive
IBM Information Archive (Information Archive) is one of the enablers for the IBM Smart
Archive Strategy, as one of its possible infrastructure elements.

Information Archive is the next-generation information retention solution designed as a
universal archiving repository for all types of content to help midsize and enterprise clients
reduce cost, manage risk, and address clients’ complete information retention needs:
business, legal, or regulatory.

Information Archive is a universal, scalable, and secure storage repository for structured and
unstructured information. Information Archive application support includes IBM ECM and
Optim with policy harmony. Information Archive replaces the IBM System Storage DR550 and
offers significant enhancements over the DR550.

This highly versatile, cloud-ready, smart business system can be a useful tool for users in
their efforts to support regulatory compliance by providing a storage repository with robust
security features designed to prevent the alteration or deletion of the storage repository in
which information is stored until your business-designated retention period has elapsed.

Information Archive is an integrated, appliance-based solution for retaining archived
information in a compliant storage environment. Information Archive connects to application
servers, receives files and documents from these applications, and stores them in a hierarchy
of disk and tape storage. The information is stored in a collection, which is the basic storage
repository within Information Archive. You can use Information Archive as the target storage
for your archiving applications or you can move information from your application or existing
storage domain to Information Archive.


You can manage archived information from a single, simple to use graphical user interface
(GUI). Information Archive scales in capacity by adding more disk storage to the collections
and scales in performance by adding more file system nodes.

Using hierarchical storage management techniques, Information Archive helps move archived
information across a hierarchy of lower cost storage devices, including tape. This can help
you to match the value of your archived information to the cost of the infrastructure on which it
is stored. Information Archive is designed to provide a quick time-to-value so you can begin to
realize its benefits very soon after.

1.3.1 Information Archive key objectives
The key objectives of Information Archive are as follows:
To provide a universal storage repository for all types of content, structured and
unstructured, compliant or non-compliant data
To eliminate complex installation and configuration
To scale easily for both capacity and performance
To support efficient policy-driven retention and tiered storage management
To support standard interfaces into the system for easy integration with applications
To protect data integrity for the entire lifespan of the information
To offer low Total Cost of Ownership (TCO) by allowing use of mixed media (disk and tape)
To support existing retention policies or enable administrators to define customized
policies
To incorporate current DR550 capabilities and much more

1.3.2 Information Archive key features
The Information Archive solution offers the following key features and characteristics:
Provides a single platform for archiving compliant, non-compliant, structured and
un-structured data thus reducing the need multiple systems.
Provides customizable data protection features to meet the industry's most stringent data
retention mandates.
Enables data archiving across multiple tiers of storage, including disk, tape and, other
near-line or offline storage, to provide massive scalability and a more cost-effective,
energy efficient archive system.
Enables specified information protection levels for archive collections. With Information
Archive, IBM has introduced a unique 3x3 architecture that allows businesses to configure
up to three archive collections on a single system with up to three servers. It allows the
flexibility for each collection to be configured with the following information protection
levels:
– Basic Protection enables the greatest flexibility for managing an organization’s data
retention needs.
– Intermediate Protection allows IT administrators to increase and decrease retention
periods as needed, but information deletion is only allowed after the retention period
has expired.
– Maximum Protection helps IT administrators manage information with strict business,
legal, or regulatory retention needs.


Enforces data retention polices that maintain data as non-erasable and non-rewritable
(NENR) until deletion is permitted by retention policy.
Enables users to archive and retrieve directly from or to their workstations as well as
enterprise content management applications.
Offers Enhanced Disaster Recovery based on advanced copy services to increase the
availability of archived documents and to prevent data loss in the event of a disaster.
Implements Enhanced Tamper Protection, a patent-pending feature that prevents root
access to the appliance to avoid modification or deletion of archived data.
Supports data deduplication, which helps to store a single instance of data on disk and
reduces the file size of documents in the archive collections. Data deduplication can
reduce the effective data size on disk by 20 to 80%.
Provides Hierarchical Storage Management, which automatically distributes and
manages data on disk, tape, or both, with the objectives of minimizing access time to data
and maximizing available media capacity.

1.3.3 Information Archive value proposition
The Information Archive value proposition can be summarized as follows:
Manage risk:
– Offers policy-based or general purpose archiving capabilities to help address
compliance and non-compliance requirements: business, legal, and regulatory
– Provides enhanced security with encryption for both disk and tape storage
– Enforces retention polices that meet some of the industry's most stringent data
retention mandates.
– Introduces new patent-pending tamper protection technology
– Locks data into non-erasable, non-rewriteable formats based on specific business
needs.
Reduce cost:
– Information Archive uses a true storage mix of disk and tape technologies combining
fast accessible disk with low cost of tape within a single archive pool.
– It can thus maximize your total cost of ownership over the life of the archived data.
Improve productivity and efficiency:
– Simple to implement (pre-integrated, pre-configured) and manage Industry standard
interface (NFS) supports immediate archiving (no custom APIs required)
– Easily scales, can dynamically add and remove storage and scales to 1 billion objects
across petabytes of storage, from multiple content types
– High performing system based on the IBM patented GPFS™ file system technology


1.4 Archiving reference architecture
A reference model describes an abstraction of the key concepts and their relationships. The
reference model referred to in this book consists of a three layer architecture as depicted in
Figure 1-2.

Layer 1 describes the application layer. Applications in Layer 1 run on computer systems that
generate, analyze, and process information and store this information as data. Typical
examples of such applications are email clients, IBM Lotus® Domino® server, Microsoft®
Exchange server, or Picture Archiving and Communication Systems (PACS).

Layer 1 applications communicate to Layer 2 components through proprietary or open
interfaces (depending on the application). Layer 2 is the archive management layer or
Document Management System (DMS), sometimes also referred to as Content Management.
Archive management components are usually running on hardware systems other than
Layer 1 and Layer 3 components.

The DMS or Content Management systems are collecting, managing, storing and retaining
data and finally transmitting the data and related information to the archive storage system
(Layer 3).

The Information Archive appliance is in Layer 3. In Chapter 8, “Integrating IBM Information
Archive with archiving applications” on page 261, you can find descriptions and practical
illustrations of how Layer 2 applications integrated with Information Archive.

Chapter 2. IBM Information Archive
overview and components
The IBM Information Archive (Information Archive) hardware and software are preinstalled
and delivered in a base rack (2231-IA3) and one optional expansion rack (2231-IS3). The
base and expansion racks (or frames) are available in various configurations and capacity
options.

In this chapter we present an overview of the Model 2231-IA3 and the optional Model
2231-IS3. First, we review the system as whole and its intended usage, followed by a
description of each of the elements, hardware, and software, with detailed information about
how they are initially packaged, installed, and configured.

2.1 Information Archive overview
The Information Archive appliance is an integrated data retention solution. It is the IBM
follow-on and replacement product for the IBM System Storage DR550. The appliance
includes preinstalled servers, disk storage, and the Information Archive software.

2.1.1 Information Archive archiving concepts and features
Information Archive brings together off-the-shelf IBM hardware and software products. The
hardware comes premounted in a secure rack. The software is preinstalled and to a large
extent preconfigured. It is designed to be easy to deploy.

Information Archive can be used to store and manage multiple billions of documents over its
deployment lifetime. Information Archive provides policy-managed storage for compliance,
archiving, and content management applications. These applications can retrieve files using
standard communication protocols, such as Network File System (NFS) and HTTP, and can
archive files using NFS or the System Storage Archive Manager API in logical containers,
called collections. The Information Archive solution includes time-based and event-based
retention options, compression and deduplication of stored data, and compatibility with
customer applications that can be used by the former DR550 appliance. Optional features of
Information Archive include remote replication for disaster recovery, high-availability server
configurations, and tape library support.

Figure 2-1 shows a general overview of the conceptual Information Archive architecture. It
depicts how applications can store documents into Information Archive over an Ethernet LAN.
The documents are archived in collections that reside on disk. The collections can be of two
types: System Storage Archive Manager collections and File Archive Collections (archive
over NFS). A maximum of three collections (in any combination of System Storage Archive
Manager Collections or File Archive Collections) is supported. The Information Archive
software includes an administrative Graphical User Interface, the Information Archive
Administration GUI (Information Archive GUI).

Figure 2-1 Information Archive architecture


The Information Archive GUI lets you administrate, operate, and monitor the Information
Archive appliance, and generate reports. The system offers the option to migrate and back up
data to tape. Although optional, tape attachment is highly desirable.

2.1.2 Information Archive security and data retention compliance features
Information Archive is primarily intended to provide a storage solution for archiving and data
retention compliance. Thus, it offers the following retention and document protection features.

Document retention
The Information Archive appliance provides a number of ways to specify how long documents
are retained.You can configure document retention policies, which provide both time-based
and event-based retention options.

Document protection settings
After a document is ingested into archival storage, it cannot be modified until its retention
period expires. You can use document protection settings to further restrict the actions that
can be taken on archived documents.

Document protection levels can be set independently for each collection in the appliance.
There are three levels of document protection available for File Archive Collections. System
Storage Archive Manager collections only support the maximum level of document protection,
which does not allow the deletion of documents or the reduction of retention periods.

Enhanced Tamper Protection
Enhanced Tamper Protection prevents root access to the servers in the Information Archive
appliance. Root access can potentially be used to modify or delete archived data. Enhanced
Tamper Protection is a system-wide setting that affects all the collections in the appliance.
This feature can be enabled during the initial configuration of the appliance, or at a later time.
After being enabled, it cannot be turned off.

If you do not enable Enhanced Tamper Protection, you must use other methods to prevent
tampering and you must securely manage the root passwords on all servers in the appliance.

Access protection
Authentication is required for access to archived documents and the Information Archive GUI.
For File Archive Collections, user accounts for administrators and archive users can be
managed using an external Lightweight Directory Access Protocol (LDAP) server. Access for
users, user groups, or host systems must be granted through the Information Archive
administrative interface. Also see Chapter 7, “LDAP environments” on page 227.

Two predefined user accounts are provided with the appliance: iaadmin and iscadmin. These
user accounts have limited authority, and are intended to be used for a specific set of tasks.
You must change the default passwords for these user accounts during the initial
configuration of the appliance.

Compliance features
Information Archive provides a number of features to enable you meet your legal, regulatory,
or policy compliance requirements for data archiving.

Chapter 2. IBM Information Archive overview and components 11

2.1.3 Information Archive hardware and software overview
The Information Archive, seen in Figure 2-2, is available in several configurations with storage
from 8 TB (one collection) up to 440 TB of raw capacity for up to three collections. Similar to
the DR550, Information Archive is also available as primary and secondary systems for a
Disaster Recovery Protection configuration, based on remote disk mirroring.

Figure 2-2 Photograph of the IBM 2231-IA3 rack

The Information Archive appliance includes Fibre Channel (FC) ports for external tape
attachment but does not include cables or tape drives or tape libraries. You must acquire and
attach tape drives to be able to back up your configuration and collection data (see
Chapter 10, “Tape attachment with IBM Information Archive” on page 403). The backup and
restore process is described in detail in Chapter 11, “Information Archive data backup and
restore” on page 441.

The software bundle includes Information Archive Version 1.2, the IBM Tivoli Storage
Manager 6.x, the IBM System Storage Archive Manager Version 6.x, Information Archive
Cluster Version, the IBM System Director Version 6.1.0, and DS Storage Manager for
Information Archive, customized for additional protection.

2.2.1 Rack and intelligent power distribution unit
This section provides details about the Information Archive rack (base and expansion
frames), as well as the integrated intelligent power distribution unit (iPDU).

Rack specifications
The Information Archive rack is a 7014-T00 rack that stacks all the components vertically. The
rack comes with doors in the front and back, and includes the Rack Security Kit to secure
physical access to any of the Information Archive appliance components. The Information
Archive 2231-IA3 (base frame) and the Information Archive 2231-IS3 rack (expansion frame)
have a height of 36U and each contains two iPDUs.

The servers and (optional) SAN and Ethernet switches are placed in the middle of the rack.
The storage units start from the bottom, populating toward the top as the storage capacity
installed increases (also see Figure 2-3 and Figure 2-4.

The hardware specifications provide detailed information for the rack, including dimensions,
electrical, power, temperature, environment, and service clearances. For more information,
see:
http://publib.boulder.ibm.com/infocenter/powersys/v3r1m5/index.jsp?topic=/iphad/f7
014t00rack.htm


Specifications for the iPDU (PDU+)
The intelligent power distribution unit (iPDU), also called power distribution unit plus (PDU+),
has power-monitoring capabilities. The iPDU is an intelligent AC power distribution unit that
monitors the amount of power being used by the devices that are plugged into it.

Figure 2-5 shows a schematic representation of the iPDU.

Figure 2-5 The iPDU - Power distribution unit with Ethernet ports

All the cabling from the iPDUs to the various Information Archive components is done by
manufacturing.

2.2.2 Cluster nodes (2231-S2M)
Information Archive includes one, or optionally up to three, Information Archive cluster nodes
(2231-S2M). Each node consists of an IBM System x (x-3650 M2, Machine Type 7947),
running a Linux®-based operating system. Cluster nodes process all the documents that
have been saved to Information Archive and perform management operations on the
documents that have been archived.

All cluster nodes have identical hardware, and they are configured as GPFS cluster nodes.

Important: Always order the same amount of memory for each server.

Physically, the System x x3550-M2 is a 2-EIA (2U), 19-inch, rack-mounted server. Up to two
quad- or dual-core Intel Xeon® 5550 Series processors with QuickPath Interconnect (QPI)
technology, up to 2.93 GHz, and up to a 1333 MHz front-side bus are available. This server
has a new energy-efficient design with low 675 W and up to 92% efficient power supplies, six
cooling fans, altimeter monitored by the Integrated Management Module (IMM) and by IBM
Systems Director Active Energy Manager™.

Up to 128 GB of high-performance, new-generation DDR-3 memory are available. It includes
ultimate internal storage flexibility with up to twelve 2.5" hot-swap SAS/SATA/SSD HDD bays.
The x3650 M2 provides four x8 (“by 8”) 8 GBps PCIe (PCI Express) Gen 2 high performance
I/O slots. It also includes two integrated Broadcom 5709C Gigabit Ethernet controllers
standard.

In Information Archive, this server is equipped with a dual quad-core processors, and has
24 GB memory installed (maximum 64 GB possible). There are also two dual-port 4 Gb FC
HBAs and two 146 GB 15k rpm SAS internal disks configured as RAID 1. One FC Ethernet
dual port card is optionally available.


Figure 2-6 shows the front view of the 2231-S2M server.

Figure 2-6 Cluster Node 2231-S2M - front view

Cluster nodes: The Information Archive Model 2231-IA3 must contain at least one cluster
node with a maximum of up to three cluster nodes.

Figure 2-7 shows the Cluster Node rear panel.

Figure 2-7 Cluster Node 2231-S2M - rear view

The minimum configuration supports a single collection with one cluster node 2231-S2M, but
this does not allow a cluster node failover.

The maximum configuration consists of three cluster nodes and supports three collections. In
this configuration, all collections support cluster node failover, but there will be a performance
degradation when more than one collection runs on a single cluster node. Each collection
needs a dedicated Storage Controller 2231-D1A (DS4200). Consequently, for more than one
collection, the configuration requires the 2231-IS3 expansion frame to mount the second and
third 2231-D1A storage controllers.


2.2.3 Information Archive Management Console
The Information Archive also includes one Management Console (IBM System x, x-3550 M2,
M/T 7946) also running a Linux-based operating system. This is your Information Archive
appliance utility server running the Information Archive Administration GUI based on the
Integrated Solutions Console (ISC). It is also used for monitoring through the preinstalled IBM
Systems Director, which provides all core RAS systems management and call home
requirements. The Management Console provides a single point of access for all functions.

The Management Console (M/T 7964 is a member of the IBM System x family (x-3550-M2).
Physically, it is a 1-EIA (1U), up to two quad-core or dual-core Intel Xeon 5500 Series
processors with QuickPath Interconnect (QPI) technology, up to 2.93 GHz, and up to 1333
MHz front-side bus, including the following features:
New energy-efficient design with low 675 W
Up to 92% efficient power supplies, six cooling fan modules, altimeter monitored by IMM,
and IBM Systems Director Active Energy Manager
Up to 128 GB of high-performance, new-generation DDR-3 memory
Ultimate internal storage flexibility with up to six 2.5" hot-swap SAS/SATA/SSD HDD bays

The system includes two PCI-Express (x16) Gen 2 slots: one half-length, full-height; and one
low-profile, as well as two integrated Broadcom 5709 Gigabit Ethernet controllers, standard.

In the Information Archive appliance, the Management Console has 4 GB of memory and two
146 GB 15k rpm SAS internal disks configured as RAID 1. Figure 2-8 and Figure 2-9 show
the front view and rear view, respectively, of the Information Archive Management Console
server.
