INTEGRATED RACK-MOUNT MODELS

Storage Computer's RAID 7 Integrated Rack-Mount storage subsystems provide 1 Gb to 234 Gb of standards-based storage power using currently available SCSI disk drives. Maximum storage capacity is 26 times the formatted capacity of the largest SCSI drive available.

MODEL R3X integrates the logic, power supplies and drive holders to support up to 18 internal 3.5" drives and four host interfaces. An additional 9 drives (Total 27) can be added using either the R3E or R5E expansion chassis. MODEL R5X integrates the logic, power supplies and drive holders to support up to 10 internal 5.25" drives and four host interfaces. An additional 17 drives (Total 27) can be added using either the R3E or R5E expansion chassis. MODEL R3E Expansion Chassis holds nine 3.5" removable expansion drives and dual hot plug power supplies. MODEL R3E Expansion Chassis holds five 5.25" removable expansion drives and dual hot plug power supplies. All four RAID 7 models can be installed in new or existing industry standard 19" cabinets.

TECHNICAL FEATURES

RAID 7 Host Interfaces are SCSI-1 and SCSI-2 (ANSI X3. 131986/ANSI X3.131-199X, ISO/IEC 316), and compatible with all SCSI systems implementing the Common Command Set, assuring connectivity and portability of RAID 7 disk arrays across most host platforms from servers to super computers. Single-ended and differential host adapters are available. A RAID 7 controller can be located up to 6 meters (S-E) or 25 meters (Differential) from the host.

Fault Tolerant Hot Pluggable N+1 power supplies with power distribution and monitoring board. LED indicators show functional status of all power supplies. Power supply failure is reported by LED, LCD display and audible alarm. Multiple, redundant fans ensure internal cooling and stable drive temperatures.

Selectable Mean Time To Repair (MTTR) rebuild modes Include: Dedicated Fast Rebuild, Interleave Rebuild, and Background Rebuild. User selectable write acknowledge modes include: UltraWrite, Fast Write, Safe Write, and Write-Thru and Verify.

Operator panel with locking mode switch. Tricolor LED monitor display for drive activity and status conditions. LCD system message display. Maintenance panel with builtin 3.5" diskette for loading operating system, test diagnostics, or optional software applications. Extensive internal diagnostics monitor disk error rates for failure prediction, and will automatically substitute a standby drive if installed.
