2.5.2 PC 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.
