CMD Technology Enhances CRD-5500 RAID Controller With Low Voltage Differential, LVD, SCSI Option.

IRVINE, Calif.--(BUSINESS WIRE)--Aug. 25, 1998--CMD Technology, Inc., a recognized leader in advanced RAID controller technology, announced today that its CRD-5500 SCSI-to-SCSI RAID controller has been enhanced to include low voltage differential (LVD) SCSI interfaces as an option.

The CRD-5500 is unique in the market in its modularity. The controller supports up to nine channels, of which, up to four can be host interfaces with the remaining channels used as disk interfaces. With the availability of this option, any or all of the nine channels can be LVD SCSI. LVD benefits users by providing longer bus lengths and better connectivity over single-ended SCSI. The option is available for both new and existing users of the CRD-5500.

"Users of the popular CRD-5500 will benefit because they can have up to 16 devices on the bus and operate at distances up to 12 meters," stated Roger Klein, CMD vice president of marketing. "Because of the CRD-5500's modularity, even customers who previously installed the product may add the new LVD SCSI capabilities to their RAID system."

The CRD-5500 is ideal for use in cluster and multi-host environments. It has up to eight Ultra SCSI Wide Single-Ended or Differential (LVD or HVD) disk channels and up to 4 Ultra SCSI Wide Single-Ended or Differential (LVD or HVD) host channels; can house up to 512 MB of cache memory; and supports RAID levels 0, 1, 0+1, 4 and 5. The connectivity of the CRD-5500 allows it to operate effectively in a multi-host environment and makes it a cost-effective choice for medium to large applications.

Two CRD-5500s can be configured together in a high-performance, active/active, dual-redundant RAID configuration. In the event one controller fails, the surviving controller automatically and transparently assumes 100 percent of the responsibilities and workload, enabling the operation to continue without interruption. The controller also implements mirrored cache memory and an advanced media management scheme, ensuring the complete protection of data. The CRD-5500 was recently certified at the NT Cluster/RAID level by Microsoft Corporation.
