SAStor14

The SAStor14 features include:-

• High capacity and density - up to 5 Tbytes per 3U chassis
• Four host Channels - two channels per controller; either Fiber Channel or Ultra 320 SCSI
• Single or Dual active controllers - each with 512, 1G or 2 Gb cache
• Up to 72,000 cached I/O's per second - approx. 40,000 per controller
• Up to 384 Mbytes/sec. throughput - RAID configuration dependant
• Any mix of 'Enterprise' SATA disks may be used - a variety of disks available
• Multiple concurrent RAID levels - supported levels 0, 1, 1+0, 3 and 5.
• Up to 256 separate LUNS may be mapped to the Hosts
• Dual pathing to a single LUN - uses both host channels per controller
• Electro-mechanical disk drive interlocks - safeguards disk removal
• Easy to use setup and management tool - WEB browser (HTML). 'Telnet' and Serial Port command line options.
• Front panel display - displays 'MAC' address for each controller as well as status information.

Any combination of disk drives may be installed to suit the chosen RAID level(s), duty cycle and capacity requirements. A single controller can support any combination of disks. * Not 'Enterprise Quality'

The SAStor14 can simultaneously support any combination of the following RAID levels on either whole disks or parts of a disk(s).

RAID 0 Data Stripe - a single 'Stripe' spanning two or more physical disks to create one logical LUN (Volume). There is no parity checking or redundancy; so if a disk fails data is lost.

RAID 1 Mirror - Two identical copies of the data are written to two disks or parts of disks to safeguard against either disk failing. Data may be read from either disk.

RAID1+0 Mirror with stripe - A 'Stripe' is created across two or more physical disks and combined with another identical Stripe to form a 'Mirror' set.

RAID 3 Data stripe with parity - A data stripe is created across two or more disks or parts with an additional disk or part used for the parity.

RAID 5 Data stripe with distributed parity - Data and its parity are distributed across three or more disks or parts of a disk

RAID levels 1, 1+0,3 and 5 provide full redundancy against a disk failure.

The SAStor14 array controller is both powerful and versatile.

• One, or two 'hot pluggable' array controllers may be fitted.
• Two full duplex host ports on each controller giving a combined throughput from cache of over 800 Mb/sec.
• Choice of either two 2 Gbit Fiber Channel or two SCSI Ultra 320 host ports.
• Combined 72,000 I/O's per sec - 36,000 per controller - from cache.
• Each may be fitted with 256, 512, 1024 or 2048 Mbytes of cache.
• Hardware created RAID levels 0, 1, 1+0 (10), 3 and 5.
• Simultaneous support for any mix of RAID level on either whole or parts of a disk or selection of disks.
• 'Dual Pathing' for high availability - any LUN (Volume) may be mapped via the two independent host channels on each controller.
• Any mix of SATA disk types (capacity or speed) is supported.
• Each controller supports up to 256 logical disks (LUN).
• Up to four loop IDs (AL_PA) can be assigned to each host channel.
• Each controller is completely independent of the other.

The SAStor14 is an extremely versatile storage array specifically designed to meet the general-purpose life cycle data needs of the enterprise. Careful selection of the most appropriate disk drives to suit the performance, duty cycle and capacity requirements of the application must be matched to the ideal RAID level.
