PCIe LP 2-x4-port SAS Adapter 3Gb (FC EL10; CCIN 57B3)
Learn about the specifications and operating system requirements for the feature code (FC) EL10 PCI Express (PCIe) adapter.
Overview
The PCIe LP 2-x4-port SAS Adapter 3Gb is a low-profile, short form factor adapter for high-performance and high-density, serial attached SCSI (SAS) applications. It supports the attachment of SAS disk, tape, and DVD by using a pair of mini SAS x4 connectors which allow the eight physical links to be used in various narrow and wide-port configurations.
The adapter is a 64 bit, 3.3 V, bootable SAS adapter that provides RAID 0, 5, 6, and 10 capability. Some RAID level support is operating system dependent. The adapter provides RAID 0, RAID 5, RAID 6, and RAID 10 for the AIX® and Linux operating systems. IBM® i operating system provides mirroring and data spreading capability. IBM i operating system does not support the RAID 5 and RAID 6 configurations for this adapter. The adapter does not have write cache. (The write performance of RAID 5 and RAID 6 can be poor on adapters that do not provide write cache. Consider using an adapter which provides write cache when using RAID 5 or RAID 6.)
The EL10 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 SAS disk drives located in a supported POWER® system unit (split disk backplane).
