Cable Card (FC 5909; CCIN 57B9)
Learn about the specifications and operating system requirements for feature 5909.
Overview
The PCI Express x8 Ext Dual-x4 3Gb SAS Adapter and Cable Card is a x8 PCI Express (PCIe) SAS
adapter combined with a cable card in a single cassette assembly. This feature provides an optimized 3/3
split DASD backplane solution within a single PCIe slot for the model 17M/MA system unit. With this
feature, three of the six internal serial-attached SCSI (SAS) disk slots (4, 5, and 6) in the system unit
enclosure are controlled by the SAS adapter contained in this feature.
The single cassette assembly goes in slot P1-C3 in the model 17M/MA system unit. The feature is not
supported in any other models.
There are three connectors on the tailstock of this single cassette assembly. The top connector ( C in
Figure 15 on page 62.) is the cable card link to the three internal SAS disk slots in the system unit. The
middle connector is covered with a label and is not used. The bottom connector ( D in Figure 15 on page
62.) is the SAS adapter.
An external AI-cable ( B in Figure 16 on page 63) connects the top connector with the bottom connector,
thereby connecting the three internal SAS disk slots to the SAS adapter. Both the top and bottom
connectors are mini-SAS 4x ports.
The SAS adapter contained in this feature is a 64-bit, bootable SAS adapter providing RAID 0, 5, 6, and
10 capability, but with no write cache.
Figure 15 on page 62 shows the PCI Express x8 Ext Dual-x4 3Gb SAS Adapter and Cable Card in a
