IBM 5805 PCIe 380MB Cache Dual x4 3Gb SAS RAID Adapter 574E 44V8581 46K6111 46K4735 5903

The IBM 574E PCIe 380MB Cache Dual x4 3Gb SAS RAID Adapter has 574ECCIN, 44V8581, 46K6111, 46K4735 part numbers, has a short, full high form factor that supports the attachment of SAS HDD and SSD in IBM Power Systems, using a pair of mini SAS 4x connectors. The IBM 574E PCIe 380MB Cache Dual x4 3Gb SAS RAID Adapter has various part numbers such as 44v8581 46k6111 46k4735 and can have 5903 or 5805 feature code. Write cache can provide an I/O performance boost even if RAID 5/6/10 is not used. From a high level perspective, except for having a larger write cache, it is very similar to the #5902 PCI-X SAS adapter and provides a high-performance connection to SAS devices. Two 574E adapters provides for mirrored write cache data and mirrored RAID parity footprints between the adapters for superior availability. The 574E is installed in pairs allowing for redundancy of the write cache. If the 574E pairing is broken, then write cache is disabled.

The 574E RAID Adapter supports several different cache batteries, including concurrent maintainable battery packs: 74Y6124 74Y5997 42R8705 44V7597 00E5724 00E5725

The IBM 574E PCIe 380MB Cache Dual x4 3Gb SAS RAID Adapter supports SAS SFF disk drives located in a PCIe 12X I/O Drawer or SAS disk drives located in an EXP 12S Disk Drawer, and requires IBM Power AIX or Linux formatted SAS drives to be attached and RAID 0, RAID-5, RAID-6 and RAID 10 are supported. 

With proper cabling and configuration, multiple wide ports are used to provide redundant paths to each dual port SAS disk or SSD.. The adapter manages SAS path redundancy and path switching should a SAS drive failure occur. The pairing of #5903 provides a high availability I/O configuration to protect against the failure of a SAS adapter. SAS X 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. The high availability I/O configuration connection is provided via the internal wiring within the PCIe 12X I/O drawer itself.
