Learn about the specifications and operating system requirements for the 5912 adapter.
Overview
The Peripheral Component Interconnect-X (PCI-X) DDR External Dual – x4 Port SAS Adapter is a low-profile adapter for high-performance and high-density, serial-attached SCSI (SAS) applications. The adapter provides two mini SAS 4x 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 AIX® and Linux®. Under the IBM i operating system, mirroring and data spreading is provided by the operating system and RAID 5 and RAID 6 is provided by the adapter.
The adapter does not have write cache. (The write performance of RAID level 5 and RAID level 6 may be poor on adapters which do not provide write cache. Consider using an adapter which provides write cache when using RAID level 5 or RAID level 6.)
The adapter can address up to 48 SAS disk drives, although the actual number of drives in a system is subject to the physical placement limitations of the system. Externally attached devices are designed to run at a data rate of 1.5 Gb/s for Serial Advanced Technology Attachment (SATA) devices, and 3 Gb/s for SAS devices. This card supports RAID and non-RAID DASD, tape, and optical devices. Feature 5912 supports the multi-initiator and high availability configurations.
Important: See the SAS RAID controller for AIX or SAS RAID controller for Linux topics for more information and important considerations for multi-initiator and high availability configurations. See also Important partitioning considerations with dual-slot and multi-adapter configurations.Figure 1. PCI-X DDR External Dual – x4 Port SAS Adapter
