Key points to note on these 46k5868 IBM 2-Port adapters:-

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 by 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, 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 Linux operating system. 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 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 Linux.

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).
