Complexity is a way of life for businesses today. An average business
must contend with five different architectures in its e-business
infrastructure. The challenge customers face is how to manage
all of these resources effectively while transforming their infrastructures.
Compounding the problem is the projected shortfall of IT skills
and the significant growth of the Internet.
This may sound like a daunting task, but IBM® is designing its IBM
eServer™ product line to be self-managing so customers can
concentrate on their business needs. At the core of many
infrastructures is the IBM eServer zSeries 900 (z900) powered by
z/OS™. Specifically designed to handle the massive growth in
transactional and data demands of the e-business world, z900 and
z/OS intelligently manage a multitude of diverse workloads within
a single server, out to the network and to data, all according to
each customer's business priorities.
z900 servers now offer 42 air-cooled models, ranging from 1- to
16-way, including 16 2xx models offering up to approximately 20
percent improvement over the original 1xx models. These servers
can be configured in numerous ways to offer outstanding
flexibility for speedy deployment of e-business solutions. Each
z900 can operate independently or as part of a Parallel Sysplex®
cluster of servers. In addition to supporting z/OS, the z900 can
host tens to hundreds of Linux images running major commercial
applications and open source applications using z/VM™.
IBM eServer product line is backed by a comprehensive suite of
offerings and resources that provide value at every stage of IT
implementation. These tools can help customers test possible solutions,
obtain financing, plan and implement applications and middleware,
manage capacity and availability, improve performance and obtain
technical support across the entire infrastructure. The result
is an easier way to handle the complexities and rapid growth of
e-business. In addition, IBM Global Services experts can help
with business and IT consulting, business transformation and total
systems management services as well as customized e-business solutions.
z900 servers are based on the z/Architecture, which enables
applications to have large memory and can help eliminate
bottlenecks associated with the lack of addressable memory. It
supports a new standard of performance and integration by
expanding on the balanced system approach of the IBM S/390®
the connected world becomes increasingly demanding, servers will
need to provide faster data access and continuous data
availability, as well as improved flexibility and efficiency of
data — all with lower cost of ownership. zSeries I/O connectivity
and networking features can help customers attain these goals.
Additions to CPU, memory and I/O capacity enables z900 to respond
quickly to workload spikes. A robust I/O subsystem complements the
great number of processors and large main memory. Native FICON and
Fibre Channel Protocol (FCP) devices provide improved performance,
greater configuration flexibility, and lower total cost through
channel consolidations. Furthermore, IBM's intent to provide FICON
cascaded director support will mean improved fiber infrastructure
utilization and additional cost savings.
High speed interconnects for TCP/IP communication, known as
HiperSockets™, let TCP/IP traffic travel between partitions at
memory speed, rather than network speed. A new, higher performing
Gigabit Ethernet feature is one of the first in the industry
capable of achieving line speed: one gigabit per second. IPv6
support enables more addresses to allow for larger configurations.
The result is ultra high speed communications within the server,
between servers, to devices and out to users, thereby allowing
greater integration between traditional and Web applications for
maximum e-business effectiveness.
Improving capacity, bandwidth, and performance is good — but
managing these resources to meet your business goals is even
better. Save time and money with zSeries self-optimizing and
servers automatically direct resources to priority work through
Intelligent Resource Director (IRD). The zSeries IRD combines
the strengths of three key technologies: Workload Manager, Logical
Partitioning and Parallel Sysplex clustering.
powerful combination of z900 servers and z/OS provides the ability
to intelligently self manage numerous operating system images
executing on a single server, as a single compute resource, with
dynamic workload management and physical resource balancing across
logical partitions. In short, the system can dynamically allocate
processors, channel paths and channel-andcontroller work across
multiple virtual servers to ensure that the unpredictable needs
of e-business workloads can be managed according to business priorities.
The zSeries and z/OS extend the power of Workload Manager from the
edge of a network to the heart of data. Business priorities are
used for realtime prioritization of network and I/O requests when
combined with Cisco technology and through the IBM Enterprise
Storage Server™. The Sysplex Distributor function of z/OS provides
intelligent load balancing of TCP/IP traffic across a Parallel
Sysplex cluster. Dynamic Virtual Internet Protocol Addressing
(VIPA) support extends the workload distribution and availability
features of Parallel Sysplex technology to the TCP/IP network.
