Expansion units 5791, 5794, and 7040-61D

Some adapters must be placed in specific PCI slots to function correctly or perform optimally. Use this information to determine where to install PCI adapters.

Overview

The model 5791 and 5794 expansion units can be ordered for the following list of IBM® System p5® servers:

The model 575 can support 1 expansion unit.
The model 590 can support up to a total of 8 expansion units.
The model 595 can support up to a total of 12 expansion units.

The model 7040-61D expansion unit can be migrated to these servers, provided the 7040-61D contains the PCI-X planar (FC 6571). Expansion units with the non-PCI-X planar (FC 6563) cannot be migrated.

Expansion unit back view

The following figure shows a back of view of the expansion unit with numbered PCI slots. The PCI slots are divided into 2 planars and 6 PCI host buses (PHBs) as shown in the illustration and described in the list that follows the illustration.

Figure 1. 7040-61D expansion unit back view with numbered slots.

PCI slot descriptions

The following list describes the PCI slots.

All slots are:
- Long
- PCI-X
- 3.3V
- 64-bit
- 133 MHz.
The slots are divided into 2 planars and 6 PHBs as follows:
- Planar 1:
  - PHB 1: slots 1, 2, 3, 4
  - PHB 2: slots 5, 6, 7
  - PHB 3: slots 8, 9, 10
- Planar 2:
  - PHB 4: slots 11, 12, 13, 14
  - PHB 5: slots 15, 16, 17
  - PHB 6: slots 18, 19, 20
All slots are compatible with PCI or PCI-X adapters.
Short adapters can go in long slots.
All slots support Enhanced Error Handling (EEH).

Recommended system unit slot placement and maximums

The following table lists the adapter feature codes that can be used in this expansion unit and the recommended slot placement and maximums.

Performance notes (for optimum performance)

For optimum performance, follow these guidelines:

No more than three Gb Ethernet ports per PHB.
No more than three high bandwidth adapters per PHB.
No more than one Extra-high bandwidth adapter per PHB.
No more than one 10 Gb Ethernet port per two CPUs in a system. If one 10 Gb Ethernet port is present per two CPUs, no other 10 Gb or 1 Gb ports allowed for optimum performance.
No more than two 1 Gb Ethernet ports per one CPU in a system. More Ethernet adapters can be added for connectivity.
If a model 5718 or 5719 adapter is placed in the system, it must be the only high-performance adapter attached to the PHB it uses. No other adapters attached to the same PHB as one of these adapters can be a high-performance adapter.
Note: The combined cumulative total for feature 5718, 5719, 5721, and 5722 is 12.
