PCIe3 x8 SAS RAID internal adapter 6 Gb (FC EJ0N and FC EJ0S; 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 EJ0N) in the 8247-42L, 8286-41A, or 8286-42A. Adding of another PCIe3 x8 SAS RAID internal adapter 6 Gb (FC EJ0S) enables the base function storage backplane (FC EJ0N) to be configured as a split storage backplane in the 8247-42L, 8286-41A, or 8286-42A.
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 8247-42L, 8286-41A, or 8286-42A. The PCIe3 x8 SAS RAID internal adapter 6 Gb is a composite feature of the base function storage backplane (FC EJ0N). The adapter contains the SAS RAID controller and SAS Expander ports. The PCIe3 x8 SAS RAID internal adapter 6 Gb is preinstalled in the dedicated internal PCIe3, x8 slot P1-C14 in the 8247-42L, 8286-41A, or 8286-42A. The internal adapter has a data read or write speed of 6 Gbps.
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 iprutils available from the IBM Linux Power Tools Repository and with the latest adapter firmware available from the Fix Central website
This configuration of the storage backplane in the 8247-42L, 8286-41A, or 8286-42A with one PCIe3 x8 SAS RAID internal adapter 6 Gb supports 12 numbers of 6.35 cm (2.5 inches), small form-factor (SFF) hard disk drives (HDDs), or solid-state drives (SSDs). FC EJ0N also supports a slim DVD bay. 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. The supported RAID is 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.
To enable the split storage backplane, another PCIe3 x8 SAS RAID internal adapter 6 Gb (FC EJ0S) must be installed in the other dedicated internal PCIe3 x8 slot P1-C15. The same backplane as in FC EJ0N 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 12 drives are then split into 2 sets of 6 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. The supported RAID is RAID 0, 5, 6, and 10. The preinstalled PCIe3 x8 SAS RAID internal adapter 6 Gb in slot P1-C14 controls drives, D7-D12, and D27 (slim DVD bay) on the direct access storage device (DASD) backplane. A PCIe3 x8 SAS RAID internal adapter 6 Gb in the other dedicated internal slot P1-C15, controls drives D1-D6 on the DASD backplane. The split storage backplane does not support the mixing of HDDs and SSDs in the same RAID. For more information regarding SAS RAID configurations with the PCIe3 x8 SAS RAID internal adapter 6 Gb, see SAS RAID configurations for system models 8286-41A or 8286-42A with feature code EJ0S .
Systems running the AIX® or Linux operating system support both adapters RAID controllers that are owned by the same or different partitions. The controllers provide RAID 0, RAID 5, RAID 6, and RAID 10 configurations for systems that are running the AIX or Linux operating system. AIX or Linux also provide mirroring (logical volume manager (LVM)) capabilities.
Systems running the IBM® i operating system do not support the two adapters if they are owned by the same partition.
