Cloud Requirements

Cloud’s basic requirements boil down to four :

Scalability
 System z Virtualization along
with Parallel Sysplex enables
near linear processor scalability

 Supports various workload
instances on a basic set of
resources (eg: Java,Linux,DB2)

 System capacity can be plugged
into existing and running
systems

 Parallel Sysplex environment
can scale near linearly from 2 to
32 system z machines

“Unchallenged Virtualization enables System utilization rates +80% and
¼ of the network costs of distributed capacity”

Virtualization
Massive virtualization capability supporting thousands of virtual Linux guests
on a single Logical Partition (LPAR).
 System z provides logical
(LPAR) and software (z/VM)
partitioning

 PR/SM enables highly
scalable virtual server
hosting for LPAR and z/VM

 IRD coordinates allocation
of CPU and I/O resources
among LPARs

“… z/VM 5.3 and above can host more then 1,000 virtual images on a
single hypervisor - topping any virtualization solution in the industry."

The value realized at the infrastructure level is then permeated into PaaS and SaaS

The Power and Flexibility of System z Virtualization
 Over 40 years of continuous innovation in virtualization technologies
 Multiple images concurrently share all physical resources
 Resources delivered as required, automatically, based on need
 New OS images can be started without affecting on-going work
 Hardware assists used to accelerate virtualization operations

Parallel SYStems comPLEX
With IBM's Parallel Sysplex technology, you can harness the power of up to
32 z systems.
 Parallel Sysplex cluster contains
multisystem data and resource
sharing technology
 The combination of Parallel
Sysplex and Intelligent Resource
Director enables your e-business
application to take full utilization
of servers’ resources
 Work requests that are associated
with a single workload can be
dynamically distributed for
parallel execution
 Manage multiple systems as a
single system from a single point
of control

“Every server in a Parallel Sysplex cluster has access to all data resources and every "cloned"
application can run on every server “

Resilience
 The System z product line is designed to offer fault tolerance to reduce single point
of failure(SPOF). Mean time between failure(MTBF) is measured in decades
 Quick retargeting of spare instances of application elements, facilitated by
virtualization
 Parallel Sysplex and Globally Dispersed Parallel Sysplex(GDPS) ensures near
continuous availability

“System z provides fault tolerance for all of its key components. This includes not just the
CPs, memory or I/O, but also the timing oscillator card, power supply, channel paths and others.”

Hyper swap feature enhances the resilience of Parallel Sysplex by facilitating the
immediate switching of PPRC mirrored disk subsystems.

 HyperSwap, a software
technology that can
seamlessly substitute Metro
Mirror (peer-to-peer
remote copy, or
PPRC), secondary devices
for PPRC primary devices

 GDPS helps automate
recovery procedures for
planned and unplanned
outages to provide
near-continuous availability
and disaster recovery
capability.

Elasticity
 The virtualization, resource
allocation and coordination are built
into the platform

 Shared everything enables less
components and a more simplistic
IT foundation

 Supports capacity upgrade on
demand (CUoD) and on/Off
Capacity on demand(on/off CoD)
that is transparent to end users

 Cost Per Image for Linux workloads is lowest for a z/VM based
private cloud by adding IFLs to existing System z infrastructure

© Satyam 2009 10


CUoD & On/Off CoD
 Capacity Upgrade on Demand
(CUoD) allows for the non
disruptive addition of central
processor capacity
 CUoD can quickly add processor
capacity up to the maximum
number of available inactive
engines.

 On/Off CoD gives you the ability
to rent hardware capacity by the
day
 You can turn on/off processing
units or Integrated Facilities from
your original configuration
 You pay only for the days the
processing units or Integrated
Facilities are turned on.
CIU (Customer Initiated Upgrade) is a Web-based solution for customers ordering and
installing permanent upgrades by creating an order on IBM Resource Link and utilizing
the System z Remote Service Facility (RSF) for downloading and activation.

Cost Per Image for Linux workloads (5 Yr TCO)

TCO over 5 years for running 100 Linux
images using five different platforms:

 Buy stand-alone x86 servers (running one
image/workload on each)
 Rent Amazon EC2 instances (running one
image/workload on each)
 Buy large x86 servers and provision virtual
servers using an x86 hypervisor (private
cloud)
 Upgrade an existing z10 EC machine and
provision virtual servers using z/VM (private
cloud)
 Buy a new z10BC machine and provision
virtual servers using z/VM (private cloud)

“Private cloud implementations built around larger virtualized System z servers
can be up to 77% less expensive than public cloud options over a five year period
and around 81% less than a distributed stand-alone server approach”

Security
 Extremely high levels of security
for guest operating systems
 Hardware Registry
 Virtual Address Space
 IOCDS Definitions
 z/VM user definition and z/VM
security is accomplished by the
z/VM directory.
 ESMs like Resource Access
Control Facility (RACF) provide
additional centralized security
functions
 The cryptographic co-processor  The z/OS IDS uses policy-based - rather
does encryption in than signature-based - identification with
hardware, reducing the capabilities for detecting and preventing not

 Every component in the box operate in full isolation for security and
recoverability.
 Components are integrated through memory-to-memory speed
