Hot-Swappable OEM Viper-II ™Ultra SCSI RAID Controller CMD’s ORD-5640 is a hot-swappable, second generation
"Viper" hardware and firmware archi-tectureOEM RAID controller. The
ORD-5640’scompact size makes it easy for the OEM to use existing enclosures or to
design custom pack-aging to take full advantage of the ORD-5640’s environ-mental
monitoring and fault tolerant features. It supports RAID 0, 1, 0+1, 4, and 5 along with
advanced fea-tures such as active/active failover and Ultra SCSI host and disk ports.
Based on CMD’s modular CRD-5500 RAID array controller, the ORD-5640 provides the same
levels of performance and advanced features in a single board. Key Benefits CMD’s ORD-5640 was designed to satisfy the most demanding requirement of today’s sophisti-cated RAID user; high performance, without compromising reliability or data integrity. The key to the ORD-5640’s outstanding performance are CMD-designed proprietary ASIC components, as well as innovative caching and RAID algorithms to provide the extremely high internal through-put required by intensive OLTP, data warehous-ing, and imaging applications.
