Workload, capacity, and performance 61
Draft Document for Review October 18, 2004 5486wrkperf.fm
High Availability Edition (HA): The High Availability Edition provides
everything the Enterprise Edition provides (including hardware that is
physically identical to the equivalent Enterprise Edition hardware), except it is
shipped with less software content. It is designed for customers who require
24 x 7 availability.
You can connect multiple IBM Eserver i5 and iSeries systems together with
high-function third-party software for role swapping and running production on
both primary and secondary servers. In this multiple iSeries server
environment, the Eserver i5 or iSeries for high availability is an attractively
priced model linked with a model of equal or higher CPW.
The High Availability Edition provides maximum 5250 CPW for 5250 OLTP
workloads. The High Availability Edition also provides support for Capacity on
Demand (permanent and temporary).
Value, Standard and Advanced Editions for iSeries Model 800: The Value,
Standard, and Advanced Editions are designed specifically for small
enterprises. Each offers a different level of capacity, power, and functionality
that support various e-business, client server and 5250 OLTP solutions.
Minimum hardware is required.
All iSeries Editions include:
Support for multiple operating systems (i5/OS or OS/400), Linux, IBM AIX 5L)
Support for Web modernization with enhanced IBM WebFacing Tool support
(the ability to deploy IBM WebFaced applications without 5250 OLTP CPW)
Support for Virtualization Engine Systems Technologies, including dynamic
logical partitioning (LPAR)
Licensing for i5/OS (WebSphere Express is integrated with i5/OS as part of
V5R3)
Some editions support 5250 OLTP applications. Each edition offers a different
level of capacity, power, and functionality.
Note: The POWER5 partitioning implementation requires a minimum of 240
CPW worth of processor power per partition. Therefore the maximum number
of partitions for the editions with 500 CPW is two and the maximum for
partitions for the editions with 1000 CPW is four. This implementation applies
to all Editions.
For information that is unique to the edition offering of each iSeries Model, see
the appropriate model chapter in this Handbook.
