PCIe3 x8 cache SAS RAID internal adapter 6 Gb (FC EL3W; CCIN 57DC) in the IBM Elastic Storage Server
Learn about the specifications and operating system requirements for the PCIe3 x8 cache SAS RAID internal adapter 6 Gb (CCIN 57DC) that is integrated with the composite storage backplane (feature code (FC) EL3W) in the IBM® Elastic Storage Server.
Overview
The high performance PCIe3 x8 cache SAS RAID internal adapter 6 Gb is an internal PCI Express generation-3 (PCIe3), serial-attached SCSI (SAS) Random Array of Independent Disks (RAID) adapter integrated in the Elastic Storage Server offering. The PCIe3 x8 cache SAS RAID internal adapter 6 Gb is part of a composite feature of the storage backplane (FC EL3W). The adapter contains the SAS RAID controller and SAS Expander ports.
- A high performance storage backplane (CCIN 2B5A) that provides slots for 8 numbers of 2.5 inches small form-factor (SFF) hard disk drives (HDDs) or solid-state drives (SDDs) and 6 of 1.8 inches SSDs. This backplane also supports a slim DVD media bay.
- A PCIe3 cache SAS RAID internal adapter (CCIN 57DC) is installed in the slot P1-C14.
- One mini-SAS HD cable that attaches to the high performance storage backplane.
The PCIe3 x8 cache SAS RAID internal adapter 6 Gb has a data read-write speed of 6 Gbps and a real write cache of 2 GB. With a 4:1 cache compression, this high performance adapter provides an increased cache of 8 GB and increases the storage system performance. The write cache contents are protected against power loss with flash memory and super capacitors and removes the need for cache battery.
One mini-SAS HD cable connects the PCIe3 x8 cache SAS RAID internal adapter 6 Gb to the SAS port on the storage backplane. The high performance internal adapter supports both the drives (SFF and SSDs) to be used in a Dual Storage IOA RAID configuration. The supported RAID configurations include: RAID 0, 5, 6, 10, 5T2, 6T2, and 10T2.
