Performance

SANnet II 200 SCSI arrays provide very high levels of performance within a compact package. The use of Ultra160 SCSI technology throughout for disks and servers results in performance approaching that of storage area networks (SAN) from a direct attached storage (DAS) solution. Cache memories of up to 1GB per array with support for 15,000RPM disks and flexible choices of hardware-based RAID level protection ensure optimum performance.

Scalability

Room for 12 disks within an enclosure that occupies just 2U of rack space provides ample capacity for many environments. A choice of 36GB, 73GB and 146GB disks permits users to balance the number of disks and storage capacity needed. When even more storage capacity is required, expansion enclosures can be added to expand the number of disks up to 24 or 36, providing up to 5.25TB of total storage capacity in just 6U of rack space.
