and IBM PureSystems offerings
This chapter provides an overview of the IBM PureSystems offerings and how IBM Flex
System V7000 Storage Node adds to a cloud ready solution within a single IBM Flex System
Enterprise Chassis. Such a solution consists of compute nodes, storage systems, LAN, and
SAN-infrastructure, allowing connectivity.
IBM Flex System products are ideally suited for data center environments that require flexible,
cost-effective, secure, with energy-efficient hardware.
The innovative design features of the IBM Flex System products make it possible for you to
configure totally integrated, customized, secure solutions that meet your data center needs
today and provide flexible expansion capabilities for the future. The scalable hardware
features and the unprecedented cooling capabilities of the IBM Flex System products help
you optimize hardware utilization, minimize cost, and simplify the overall management of your
data center.
The primary focus of this book is to describe features and functions of IBM Flex System
V7000 Storage Node. However, in early versions of the IBM Flex System, the integrated
storage is provided by IBM Storwize V7000. Further developments were made from the time
of initial product GA announcement, and IBM Flex System V7000 Storage Node is now
supported as an integrated storage inside the IBM Flex System chassis. Hence this
introduction covers both storage systems. In the following chapters, IBM Flex System V7000
Storage Node and its functions are described.

1.1 IBM PureSystems overview
During the last 100 years, information technology has moved from a specialized tool to a
pervasive influence on nearly every aspect of life. From tabulating machines that simply
counted with mechanical switches or vacuum tubes to the first programmable computers, IBM
has been a part of this growth, while always helping customers to solve problems.
Information Technology (IT) is a constant part of business and of our lives. IBM expertise in
delivering IT solutions has helped the planet become smarter. And as organizational leaders
seek to extract more real value from their data, business processes and other key
investments, IT is moving to the strategic center of business.
To meet those business demands, IBM is introducing a new category of systems, systems
that combine the flexibility of general-purpose systems, the elasticity of cloud computing and
the simplicity of an appliance that is tuned to the workload. Expert integrated systems are
essentially the building blocks of capability. This new category of systems represents the
collective knowledge of thousands of deployments, established best practices, innovative
thinking, IT leadership, and distilled expertise.
The offerings in IBM PureSystems are designed to deliver value in the following ways:
Built-in expertise helps you to address complex business and operational tasks
automatically.
Integration by design helps you to tune systems for optimal performance and efficiency.
Simplified experience, from design to purchase to maintenance, creates efficiencies
quickly.
IBM PureSystems offerings are optimized for performance and virtualized for efficiency.
These systems offer a no-compromise design with system-level upgradeability. IBM
PureSystems is built for cloud, containing “built-in” flexibility and simplicity.
At IBM, expert integrated systems come in two types:
IBM PureFlex System: Infrastructure systems deeply integrate the IT elements and
expertise of your system infrastructure.
IBM PureApplication™ System: Platform systems include middleware and expertise for
deploying and managing your application platforms.
IBM PureSystems are built for cloud with integrated elasticity and virtualization capabilities to
provision new services in minutes and improve business flexibility while reducing cost.
IBM Flex System is a build-to-order offering that is integrated by the client or a partner and
does not deliver against all of the three attributes of expert integrated systems (built-in
expertise, integration by design, simplified experience). IBM Flex System allows clients to
build their own system to meet unique IT requirements with a set of no-compromise
components including compute, storage, networking, and systems management.
IBM PureFlex System and IBM PureApplication System are built on elements of the IBM Flex
System. It has been designed for clients that need pre-integrated hardware infrastructure
comprised of compute, storage and networking nodes as well as a choice of operating
systems and hypervisors.
The new offering, IBM Flex System V7000 Storage Node, is supported with IBM PureFlex
System and other IBM Flex System configurations.

understanding of smarter computing. These IT best practices and standards are infused
throughout the system.
With IBM PureApplication System, you enjoy the following benefits:
IBM builds expertise into preintegrated deployment patterns, which can speed the
development and delivery of new services.
By automating key processes such as application deployment, PureApplication System
built-in expertise capabilities can reduce the cost and time required to manage an
infrastructure.
Built-in application optimization expertise reduces the number of unplanned outages
through best practices and automation of the manual processes identified as sources of
those outages.
Administrators can use built-in application elasticity to scale up or to scale down
automatically. Systems can use data replication to increase availability.
Patterns of expertise can automatically balance, manage, and optimize the elements
necessary, from the underlying hardware resources up through the middleware and software.
These patterns of expertise help deliver and manage business processes, services, and
applications by encapsulating best practices and expertise into a repeatable and deployable
form. This best-practice knowledge and expertise has been gained from decades of
optimizing the deployment and management of data centers, software infrastructures, and
applications around the world.
These patterns help you achieve the following types of value:
Agility: As you seek to innovate to bring products and services to market faster, you need
fast time-to-value. Expertise built into a solution can eliminate manual steps, automate
delivery, and support innovation.
Efficiency: To reduce costs and conserve valuable resources, you must get the most out of
your systems with energy efficiency, simple management, and fast, automated response
to problems. With built-in expertise, you can optimize your critical business applications
and get the most out of your investments.
Increased simplicity: You need a less complex environment. Patterns of expertise help you
to easily consolidate diverse servers, storage and applications onto an easier-to-manage,
integrated system.
Control. With optimized patterns of expertise, you can accelerate cloud implementations
to lower risk by improving security and reducing human error.
IBM PureApplication System is available in four configurations. These configuration options
enable you to choose the size and compute power that meets your needs for application
infrastructure. You can upgrade to the next size when your organization requires more
capacity, and in most cases, you can do so without application downtime.

1.2.1 Highlights
Each system consists of IBM System x® nodes, IBM Power Systems™ compute nodes, or a
combination of these two types, which is known as a hybrid configuration. The bundled,
on-site services provide some initial compute node configuration and might differ for IBM
System x nodes and Power Systems compute nodes. A client-specified primary node
(POWER or x86) is pre-configured with a hypervisor (IBM PowerVM®, VMWare, KVM,
HyperV) to allow virtual server configuration by IBM services personnel. Services also include
skills transfer to the client personnel.
Important: Initial IBM PureFlex System configuration is carried out by IBM services and is
included with the purchase. To ensure configuration success, the default shipped
configuration must not be changed until these services are completed by IBM.

Storage components
The storage capabilities of IBM Flex System allows you to gain advanced functionality with
storage nodes in your system while taking advantage of your existing storage infrastructure
through advanced virtualization. For early versions of the IBM Flex System, the only
integrated storage was the IBM Storwize V7000 that was external to the IBM Flex System
Enterprise Chassis. With the introduction of IBM Flex System V7000 Storage Node, storage
is provided internally from the IBM Flex System Enterprise Chassis.
Simplified management
The IBM Flex System simplifies storage administration with a single user interface for all your
storage with a management console that is integrated with the comprehensive management
system. These management and storage capabilities allow you to virtualize third-party
storage with non-disruptive migration of the current storage infrastructure. You can also take
advantage of intelligent tiering so you can balance performance and cost for your storage
needs. The solution also supports local and remote replication and snapshots for flexible
business continuity and disaster recovery capabilities.
Chapter 1. Introduction to IBM Flex Systems and IBM PureSystems offerings 9
Infrastructure
The IBM Flex System Enterprise Chassis is the foundation of the offering, supporting
intelligent workload deployment and management for maximum business agility. The 10U
high chassis has the capacity of up to 14 compute nodes, or a mix of compute nodes and
Storage, which mounts from the front. From the rear, it mounts power supplies, fans, and
different options of LAN and SAN switches. The IBM Flex System Enterprise Chassis delivers
high-performance connectivity for your integrated compute nodes, storage, networking, and
management resources. The chassis is designed to support multiple generations of
technology and offers independently scalable resource pools for higher utilization and lower
cost per workload.
We now review the various components of the IBM Flex System in order to understand how
IBM Flex System V7000 Storage Node integrates with the PureFlex Systems solution. All of
the components are used in the three pre-integrated offerings to support compute, storage,
