Subscribe to this informationPlacement rules for the high-performance SCSI disk controller in an IBM i controlled system
Determine which PCI slots can accommodate the 5746, 5778, 5781, and 5782 SCSI disk controllers on IBM® Power Systems™ running the IBM i operating system.
Overview and prerequisites
This section provides special placement information for the SCSI disk controllers and auxiliary-write cache adapters listed in Table 1.
If you are installing a new feature, ensure that you have the software required to support the new feature and determine whether there are any existing program temporary fix (PTF) prerequisites to install. To do this, use the IBM Prerequisite website.
Then go to 5796 expansion unit to determine which PCI slots can accommodate these adapters.
| Feature codes | CCIN numbers | Description | Variables |
|---|---|---|---|
| 5778 | 571F and 575B | PCI-X Ultra320 SCSI Disk Controller with auxiliary-write
cache Double-wide adapter. 571F is the controller. 575B is the auxiliary-write cache. |
No IOP |
| 5782 | 571F and 575B | PCI-X Ultra320 SCSI Disk Controller with auxiliary-write
cache Double-wide adapter. 571F is the controller. 575B is the auxiliary-write cache. |
No IOP |
5796 expansion unit
The 5583 adapter is not supported on the 5796.
The double-wide 571F/575B adapter is supported in the slots shown in the Allowed slots column.
| Feature codes | CCIN numbers | Description | Variables | Allowed slots |
|---|---|---|---|---|
| 5782 | 571F and 575B | PCI-X Ultra320 SCSI Disk Controller with auxiliary-write cache | IOPless |
1, 42 2, 53 3, 64 |
1Double-wide adapter, requires 2 adjacent slots. The SCSI controller side of the adapter pair requires a 64-bit slot. 2These slots can be used for the SCSI controller side (571F) of the adapter. 3These slots can be used for either side of the adapter. 4These slots can be used for the cache side (575B) of the adapter. |
