2.5.2PC ServeRAID SCSI Adapter

The ServeRAID Adapter is a high-performance, three-channel PCI RAID adapter. This technologically advanced RAID controller supports up to 45 SCSI-2 Fast/Wide or UltraSCSI hard drives to satisfy mission critical applications that require protection for large amounts of data.

The ServeRAID Adapter achieves outstanding performance through the use of a RISC processor, 4 MB of cache, and a dual PCI bus architecture with a local PCI bus. These attributes significantly improve system performance by reducing traffic on the system local bus and by rapidly processing complex RAID algorithms with a high-speed processor.

IBM incorporates logical drive migration with the ServeRAID Adapter. This new technology allows changes to be made to the RAID configuration while the PC Server is up and running. Using online utilities, new RAID arrays can be added and RAID levels modified without deleting the original array, or requiring the data to be restored from a backup source.

For added security, the ServeRAID Adapter stores critical RAID configuration information in multiple locations on the adapter and hard disk making disaster recovery or migrating hard drives from one server to another quick and easy. This means hard drives can now be removed from your server and installed in another server or external enclosure in any order. The ServeRAID Adapter takes care of getting the configurations from the hard drives and remapping them as necessary.

This adapter contains three internal connectors, one for each channel, and one external connector. Three of the four connectors can be used for attachment of SCSI devices.
