Learn about the specifications and operating system requirements for feature code (FC) 5911 adapters.
Overview
The SAS adapter for internal Split DASD option is an x8 PCI Express (PCIe) serial-attached SCSI (SAS) adapter combined with a cable card in a single cassette assembly.
Three mini SAS 4x connectors are on the tailstock of this cassette assembly. The top connector (T2) is the cable card link to the system's SAS backplane. The other two connectors are for the PCIe SAS adapter within the 5911 assembly. A one meter SAS cable (feature 3679) is used to connect the top mini SAS 4x connector to either of the lower mini SAS 4x connectors, thereby connecting the three internal SAS disk slots to the SAS adapter within the 5911 assembly. The remaining mini SAS 4x connector (either of the lower connectors) can be attached to an EXP 12S Disk Drawer or a SAS removable media expansion unit.
The SAS adapter contained in this feature is a 64-bit, bootable SAS adapter providing RAID 0, 5, 6, and 10 capability. The adapter does not provide write cache. Write performance of RAID 5 and RAID 6 might be poor on adapters that do not provide write cache. Consider using RAID 0 or 10 when using this adapter.
This feature cannot be used in a multi-initiator, high availability configuration using two adapters in a dual controller mode.
The following figure shows the adapter.
