CMD adds LVD to RAID controllers
This month, CMD Technology added support for low-voltage differential (LVD) to its CRD-5640 line of Ultra SCSI RAID controllers. CMD (Irvine, CA) already sells high-voltage differential and single-ended implementations of the 5640, which is a hot-pluggable device with active-active, dual-redundant controllers. In the event of a failure, the redundant controller assumes the workload for uninterrupted operation. The failover is handled by CMD`s AutoRebind technology. Other features include mirrored cache memory, a media management scheme that protects data in the event of a failure, and support for as many as 42 SCSI devices. The CRD-5640 comes in a 5.25-inch full-height canister.
