PCIe3 x8 SAS RAID internal adapter 6 Gb (FC EJ1F, FC EJ1H, FC EL66, and FC EL68; CCIN 57D7)

Learn about the specifications and operating system requirements for the PCIe3 x8 SAS RAID internal adapter 6 Gb (CCIN 57D7) that is integrated with the base function storage backplane (FC EJ1F) in the 5105-22E, 9008-22L, 9009-22A, 9009-22G, 9223-22H, or 9223-22S system. Adding of another PCIe3 x8 SAS RAID internal adapter 6 Gb (FC EJ1H or FC EL68) enables the base function storage backplane (FC EJ1F) to be configured as a split storage backplane in the 5105-22E, 9008-22L, 9009-22A, 9009-22G, 9223-22H, or 9223-22S.

Overview

The PCIe3 x8 SAS RAID internal adapter 6 Gb is an internal PCI Express (PCIe) generation 3 (Gen3), serial-attached SCSI (SAS) Random Array of Independent Disks (RAID) adapter that is integrated in the 5105-22E, 9008-22L, 9009-22A, 9009-22G, 9223-22H, or 9223-22S. The PCIe3 x8 SAS RAID internal adapter 6 Gb is part of a composite feature of the base function storage backplane (FC EJ1F). The adapter contains the SAS RAID controller. The PCIe3 x8 SAS RAID internal adapter 6 Gb is preinstalled in the dedicated internal PCIe3, x8 slot P1-C49 in the 5105-22E, 9008-22L, 9009-22A, 9009-22G, 9223-22H, or 9223-22S. The internal adapter has a data read or write speed of 6 Gbps.

Adapter caching

The PCIe3 x8 SAS RAID internal adapter 6 Gb does not have a non-volatile write cache. However, Linux® customers can take advantage of a volatile adapter write cache of up to 1 Gb (compressed) for improved performance. This support is available with the 2.4.10 version of IBM Power RAID adapter utilities (iprutils) available from the IBM Linux Power Tools Repository and with the latest adapter firmware available from the Fix Central website .

Single adapter configuration

This configuration of the storage backplane in the 5105-22E, 9008-22L, 9009-22A, 9009-22G, 9223-22H, or 9223-22S with one PCIe3 x8 SAS RAID internal adapter 6 Gb (FC EJ1F) supports 8 numbers of 6.35 cm (2.5 inches), small form-factor (SFF) hard disk drives (HDDs), or solid-state drives (SSDs). The PCIe3 x8 SAS RAID internal adapter 6 Gb supports the drives to be used as just-a-bunch of disks (JBOD) or as a RAID array. The supported RAID levels are RAID 0, 5, 6, and 10. Two mini-SAS HD cables connect the PCIe3 x8 SAS RAID internal adapter 6 Gb to the two SAS ports on the storage backplane. This configuration with one PCIe3 x8 SAS RAID internal adapter 6 Gb does not split the disks in the storage backplane.

Two adapters split storage backplane configuration

To enable the split storage backplane, another PCIe3 x8 SAS RAID internal adapter 6 Gb (FC EJ1H or FC EL68) must be installed in the other dedicated internal PCIe3 x8 slot P1-C50. The same storage backplane as in FC EJ1F is used in the split storage backplane configuration. The two mini-SAS HD cables connect each of the PCIe3 x8 SAS RAID internal adapter 6 Gb to the two SAS ports on the storage backplane. The 8 drives are then split into 2 sets of 4 drives (HDDs or SSDs), each controlled by one PCIe3 x8 SAS RAID internal adapter 6 Gb. The split storage backplane configuration supports the drives to be used as just-a-bunch of disks (JBOD) or as a RAID array. The supported RAID levels are RAID 0, 5, 6, and 10. The preinstalled PCIe3 x8 SAS RAID internal adapter 6 Gb in slot P1-C49 controls drives, D1, D2, D3, and D7 on the direct access storage device (DASD) backplane. A PCIe3 x8 SAS RAID internal adapter 6 Gb in the other dedicated internal slot P1-C50, controls drives D4, D5, D6, and D8 on the DASD backplane.
