- Optimized for integration, and designed to
handle the transaction processing demands of the e-business world
with attractive price/performance
- Incorporates advanced self-management capabilities from IBM®
- Provides outstanding flexibility for deploying Linux® solutions
with a dedicated Linux server
Built on proven technology
It's a conundrum that many IT managers know all too well. How
does a company build and maintain an IT infrastructure while
facing evolving technology with limited budgets and multiple types
of workloads? How does a company reconcile the need for high
availability with security and a variety of servers, storage and
software that must work together seamlessly? To help customers
meet these challenges, IBM introduces the IBM zSeries™ 800 (z800)
servers.
As part of the IBM product line, z800 servers
are built on the same guiding principles that make the IBM brand
technologically advanced. These breakthrough servers provide new
tools, innovative technology and application flexibility to help
businesses lower costs, improve efficiency and expedite e-business
transformation. Built on the same high security and powerhouse
processing capabilities of the successful IBM zSeries 900 (z900),
z800 servers are specifically optimized to integrate business
applications, and to meet the critical transactions and evolving
demands of e-business.
The attractive price/performance of z800 servers
extends the advantages of advanced zSeries technology to customers
whose capacity requirements are less than those served by the
z900.
Advanced design
z800 and z900 servers are designed from the ground up using key
technologies from the IBM Autonomic Computing initiative, the
IBM blueprint for self-managing systems. By using technology to
manage technology, autonomic computing can help create an intelligent,
self-managing IT infrastructure to minimize complexity. This enables
increased utilization of technology without the spiraling pressure
on critical skills and software, as well as service and support
costs.
The best example of this is the revolutionary z/Architecture™—the
most extensive design effort in four decades of large-scale
computing.
As the foundation of zSeries servers, the z/Architecture
provides optimal flexibility in selecting, building and rapidly
deploying applications across a customer's e-business infrastructure,
while taking advantage of zSeries availability. It is designed
to keep your business up and running.
Work priority is managed by the Intelligent Resource Director that
works with the z/OS™ Workload Manager and is designed to
automatically allocate physical resources to the task that needs
it most.
Under the covers
All z800 servers have a five Processor Unit (PU) MultiChip
Module. The first PU is, in most cases, designated as a general
purpose engine with Processor Units two through four defined as
general purpose, Integrated Facility for Linux or Coupling
Facility engines for use in a Parallel Sysplex® cluster.
The fifth PU is used as a System Assist Processor (SAP) to drive
large amounts of data through the I/O subsystem. A spare PU is
available as a backup to any processing units that might fail.¹
HiperSockets™ exploits central memory communication functions and
transmits data at memory speed between Logical Partitions (LPARs)
or virtualized guests on z800 systems. HiperSockets is key in
building internal LANs between LPARs and driving multiple
workloads across tens to hundreds of virtual servers within a
single, physical machine for an effective "network in a box."
In
addition to supporting traditional workloads, z800 servers can
host tens to hundreds of Linux images running major commercial
applications using z/VM™ Version 4.1 and subsequent releases. z/VM
enhanced technology and new functions are designed to provide
outstanding virtualization capabilities.
