iSeries Model 595 177
Draft Document for Review October 18, 2004 5486m595.fm
The Model 595 32/6-way supports four processor books with a total of twenty
four HSL-2/RIO-G loops with a maximum of 60 I/O towers across all loops.
The speed of the HSL-2/RIO-G is 2 GBps compared to the previous HSL-2
adapters operating at 1 GBps.
The following rules apply to towers that are supported at these higher speeds:
New #5094, #5294, #0595, and #5095 come with a #9517 HSL-2/RIO-G
adapter.
HSL-2 adapters in existing #5094, #5294, #0595, and #5095 towers must be
replaced with a #6417 HSL-2/RIO-G Bus Adapter.
Mixing of HSL and HSL-2 towers is permitted with the correct combination of
cables.
See “High-speed link” on page 293 for information about supported HSL cables
and HSL loop maximums.
You can find further information in High-speed Link Loop Architecture for the IBM
Eserver iSeries Server: OS/400 Version 5 Release 2, REDP-3652, and the HSL
Rules presentation available at:

Model 595 PCI cards and features
The Model 595 is a Peripheral Component Interconnect (PCI)-based technology
system. The number of PCI cards that can be supported in a Model 595 depends
on the number of I/O tower is attached and the number of PCI slots. PCI card
placement rules and LPAR configuration considerations also affect the number of
slots supported.
See the Summary table on page 159 for the number of maximum features
supported by the total system and in the Model 595 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 “AIX and Linux direct attach features overview” on page 342 for the
supported Linux Direct Attach features.
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.
