5278-8202 - IBM Power7 E4B, PCIe LP 2-x4-port SAS Adapter 3Gb

IBM Power7 8202-E4B (#5278) - PCIe LP 2-x4-port SAS Adapter 3Gb

This feature is the Low Profile (LP) equivalent of feature number 5901. The #5901/5278 PCIe Dual-4x SAS Adapter is a low-profile short form factor adapter which supports the attachment of SAS disk, tape, and DVD using a pair of mini SAS 4x connectors. From a high level perspective, it is functionally equivalent to the #5912 PCI-X SAS adapter and provides a high-performance connection to SAS devices.

The #5901/5278 supports external SAS tape drives such as the 36/ 72 GB DAT72, 80/160GB DAT160, and 800/1600GB LTO-4 found in the IBM tape units such as the 7214-1U2, TS2240, TS2340, TS3100, TS3200, and TS3310. Other removable media devices supported include IBM SAS/SATA DVD-ROM/RAM drives. SAS adapter-to-enclosure (AE) cables are used to attach these drives.

The #5901/5278 supports SAS SFF disk drives located in a PCIe 12X I/O Drawer or SAS disk drives located in an EXP 12S Disk Drawer or drives in a POWER6 or POWER7 system CEC (split DASD backplane). AIX/ Linux formatted SAS drives are supported with RAID 0 (with mirroring) and RAID 10. IBM i formatted SAS drives are supported and data spreading and mirroring functions are provided by IBM i. RAID-5 or RAID-6 are not supported on the #5901/5278. #5901/5278 has zero write cache. CCIN for #5901/5278 is 57B3.

With proper cabling and configuration, multiple wide ports are used to provide redundant paths to each dual port SAS disk . The adapter manages SAS path redundancy and path switching should a SAS drive failure occur. SAS Y cables attach SAS disk drives in an EXP 12S Disk Drawers. SAS #3688 cables attach SFF SAS drives in an PCIe 12X I/O Drawer. In the EXP 12S Drawer, a high availability I/O configuration can be created using a pair of #5901, a pair of 5278 or a paired 5901/5278 adapters and SAS X cables to protect against the failure of a SAS adapter. In the PCIe 12X I/O Drawer, this function is provided via the internal wiring within the drawer itself.
