Note 1 CPW is used to measure the performance of all iSeries and AS/400e processors announced from September
1996 onward. The CPW value is measured on maximum configurations. The type and number of disk devices,
the number of workstation controllers, the amount of memory, the system model, other factors, and the
application running determine what performance is achievable.
Note 2 There must be one DVD-RAM or DVD-ROM in the #9094 Base PCI I/O Enclosure.
Note 3 One line is used if #5544 System Console on Operations Console is used. One line might be used if the #5546
or #5548 System Console on LAN is selected and the #0367 Operations Console PCI Cable must be
connected.
Note 4 External DASD capacity assumes 70.56 GB LUNs. External DASD cannot exceed the maximum new system
capacity or the maximum number of disk arms.
Note 5 5250 CPW (Interactive) is an approximate value that reflects the amount of Processor CPW that can be used
for workloads performing 5250-based tasks. The iSeries Enterprise Edition provides maximum 5250 CPW
support (up to 100% of the capacity of the active processor CPW).Remember that:
Any task that uses a 5250 data stream is considered 5250 online transaction processing (OLTP) work
and requires some amount of 5250 CPW to process regardless of how the task was started.
A task submitted through a 5250 session (5250 device or 5250 emulation) that does display or printer I/O
requires 5250 CPW.
A task submitted through a 5250 session (5250 device or 5250 emulation) as a "batch" job is not
considered 5250 OLTP work and does not require any 5250 CPW unless the task does display or printer
I/O.
Limited 5250 CPW is available with the Standard Edition for a system administrator who wants to use
5250 display device I/O to manage various aspects of the server. Multiple administrative jobs exceed this
capability.
Maximum 5250 CPW is equivalent to the Processor CPW for the active processor.
