Product Name: PCIe Dual – x4 SAS Adapter
Marketing Information:

The PCI Express® (PCIe) Dual – 4x SAS Adapter 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 using a pair of mini SAS 4x connectors which allow the eight physical links to be used in various narrow and wide-port configurations. The adapter does not have write cache.

The adapter is a 64-bit, 3.3 V, bootable SAS adapter that provides RAID 0 and RAID 10 capability. Some RAID level support is operating system dependent. The adapter provides RAID 0 and RAID 10 for AIX® and Linux. Under the IBM® i operating system, mirroring and data spreading is provided by the operating system. The adapter does not have write cache.

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 Gbps for serial ATA (SATA) devices, and 3 Gbps for SAS devices. This card supports RAID and non-RAID DASD, tape, and optical devices. This adapter supports the multi-initiator and high availability configurations in AIX and Linux. IBM i does not support feature 5901 in multi-initiator and high availability configurations.

Important: See the following topics for more information and important considerations for multi-initiator and high availability configurations: SAS RAID controllers for AIX, SAS RAID controllers for IBM i, or SAS RAID controllers for Linux. See also Important partitioning considerations with dual-slot and multiadapter configurations.

The 5901 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).
