Model 825 PCI cards and features
The Model 825 is a PCI-based technology system. Since migration towers
cannot attach to the Model 825, System Products Division (SPD) cards in
systems or towers migrating to the Model 825 must be replaced with PCI card
equivalents. Refer to “Hardware no longer marketed by IBM” on page 840 for a
list of SPD functions not supported by PCI adapters.
See the table on page 100 for the number of maximum features supported by the
total system and in the Model 825 system unit. See Chapter 17, “iSeries I/O
processors” on page 319, and Chapter 18, “iSeries I/O adapters and controllers”
on page 339, for full descriptions of the features that are supported. See “Not all
features are supported on all models. Some features may be withdrawn but are
in the table for reference. AIX specific adapters are not described in this book.” on
page 344 for supported Linux Direct Attach features.
External towers
Migration towers are not supported on the Model 825. PCI towers are supported
with upgrades for migration only.
Refer to Chapter 15, “Towers, racks, and high-speed link” on page 259, for
information about supported towers for the Model 825, and “Summary of the
iSeries expansion units and towers” on page 105 for a table of configuration
maximums.
Important: The Model 825 has a unique set of rules that influence the
maximum number of components on a HSL loop. As such, rules specific to the
Model 825 warrant a more detailed description than what is presented in
High-speed Link Loop Architecture for the IBM Eserver iSeries Server:
OS/400 Version 5 Release 2, REDP-3652. TechNote iSeries Model 825
High-speed Link Loop, TIPS0297, complements this Redpaper.
Note: The placement of PCI cards follows special rules. Refer to “PCI card
technology” on page 340 and PCI Card Placement Rules for the IBM
Eserver iSeries Server Version 5 Release 2, REDP-3638, before you
propose any configuration.
