High-performance SCSI and SAS controller placement

Determine which PCI slots can accommodate the 0649, 2780, 5580, 5582, 5583, 5590, 5738, 5739, 5746, 5777, 5778, 5781, 5782, 5799, 5800, 5904, and 5908 controllers on IBM® System i5® and eServer™ i5 models.

Overview and prerequisites

This section provides special placement information for the SCSI and SAS controllers and auxiliary-write cache adapters listed in Table 1. This information supplements the placement information in Determine the best place to install your adapter.

If you are installing a new feature, ensure that you have the software required to support the new feature and that you determine if there are any existing PTF prerequisites. To do this, use the IBM Prerequisite Web site at http://www-912.ibm.com/e_dir/eServerPrereq.nsf Link outside information center .

Use the list in Table 1 to cross-reference adapter feature codes with their CCIN numbers and descriptions. See also the adapter tables in Determine the best place to install your adapter for more detailed descriptions, notes, and restrictions for these adapters.

Then go to one of the following system or expansion unit tables to determine which PCI slots can accommodate these adapters.

5094 or 5294 expansion unit
5096 or 5296 expansion unit
5088 or 0588 expansion unit

5790 expansion unit
520 system unit with 1.5 and 1.6 GHz processors (CCIN numbers 28D2, 5228, 5229, and 522A)
520 system unit with 1.9 GHz, POWER5+ processors (CCIN numbers 8325, 8327, 8330, 53C6, 53C2, and 53C3)
550 system unit with 1.6 GHz processors (CCIN number 5237)
