PCI slot priorities for the 5797 and 5798 expansion units

Find information about the placement rules and slot priorities for the Peripheral Component Interconnect (PCI), PCI-X, and PCI Express (PCIe) adapters that are supported for the I/O expansion units.

Expansion unit rear view

The 5797 and 5798 are 24-inch, I/O expansion units that attach to the system by using 12X cables.

PCI-X slot descriptions

Table 1 shows the slot properties for this expansion unit. All slots are long. Slots 1 - 7 and 11 - 17 each have a dedicated PCI host bridge (PHB). Slots 8 - 10 share a PHB with each other and with two Small Computer System Interface (SCSI) buses (SCSI-1 and SCSI-2) on the same planar. Slots 18 - 20 share a PHB with each other and with two SCSI buses (SCSI-3 and SCSI-4) on the same planar.

  • All slots are compatible with PCI or PCI-X adapters.
  • All slots are long slots. Short adapters can go in long slots.
  • All slots support enhanced error handling (EEH).

Slot placement and maximums

Table 2 shows slot placement priorities and the maximum number of specified adapters allowed for connectivity by feature code (FC). However, for optimum performance, you might want to further limit the total number of high bandwidth and extra-high bandwidth adapters. Performance notes follow the table.

4FC 5782 is a double-wide adapter pair. The CCIN 571F and 575B adapters can be placed in slots 1, 2, 3, 4, 5, 6, 7, 11, 12, 13, 14, 15, 16, and 17. The double-wide adapter requires two adjacent slots. The SCSI controller side of the adapter pair requires a 64-bit slot. Slots 1 and 11 can be used to install the SCSI controller side (571F) of the adapter. Slots 2, 3, 4, 5, 6, 12, 13, 14, 15, and 16 can be used for either side of the adapter. Slots 7 and 17 can be used for the cache side (575B) of the adapter.

Performance notes

Use the information in this section to help determine the maximum number of adapters that can be placed in a system while still maintaining optimum performance.

Table 2 shows the maximum number of adapters allowed for connectivity. However, for optimum performance, you might want to further limit the total number of high-bandwidth and extra-high bandwidth adapters. Use the following guidelines for connecting the adapters:

  • Attach no more than three Gb Ethernet ports per PHB.
  • Attach no more than three high-bandwidth adapters per PHB.
  • Attach no more than one extra-high bandwidth adapter per PHB.
  • Attach no more than one 10 Gb Ethernet port per two processors in a system. If one 10 Gb Ethernet port is present per two processors, no other 10 Gb or 1 Gb ports are allowed for optimum performance.
  • Attach no more than two 1 Gb Ethernet ports per one processor 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 can be attached to the same PHB because one of these adapters can be a high-performance adapter.
    Note: The combined cumulative total for features 5718, 5719, 5721, and 5722 is 12.
Note: When using extra-high performance adapters, cable the 5797 and 5798 drawers by using point-to-point cabling rather than by using a daisy chain. Daisy chaining the drawers puts more adapter slots onto the 12X links and this degrades the performance.
