RAID (Redundant Array of Inexpensive Disks)
DAS, often referred to as RAID includes both fixed and removable storage devices. Typically, these devices are hard disks. A fixed storage device is any storage device defined during system configuration to be an integral part of the system DAS. If a fixed storage device is not available at some time during normal operation, the operating system detects an error.
DAS Storage Array that uses either low cost fully integrated SATA (Serial ATA), UltraSCSI or Fibre Channel hard disks to form a RAID subsystem for use with Microsoft Windows NT (Intel and Alpha), Windows 2000, 2003, Novell NetWare, OpenVMS, Tru64 UNIX, SUN Solaris, IBM AIX, and HP-UX operating systems. DAS ensures continuous access to critical applications and data through dual active- active controllers with fail over and fail back, hot swap components, disk failover to hot spares, automatic monitoring, and event notification. It incorporates the latest in RAID technology, providing RAID levels 0, 1, 0+1, 4, 5, and non RAID disks (JBOD). DAS can support two independent hosts or one independent cluster.
DAS is positioned as a low cost storage solution and is ideal for clients who need a small, shared RAID storage subsystem for a two node cluster.
