Features
Multiple RAID level support
Online expansion allows drive(s) to be added with existing logical drives
Array configuration and management without special software or drivers
Support for all popular operating system environments (works
independent from the OS)
Connect up to 15 physical drives per drive channel
Drives can be grouped and managed as a single very large array, as multiple
large capacity drive groups, or as individual disk drives
Industry standard Fast-20/Wide SCSI-3 (Ultra Wide) interface
Software utility (AdminiStor PC Utilities) provides DOS-level control
through a PC running ASPI drivers or Windows NT Pass-Through
Serial communications permits array control through a standard VT100 (or
equivalent) terminal
Automatic failed-drive detection
Supports AEMI protocols for automatic rebuild of the array using a
stand-by (hot spare) disk after a drive failure
Transparent drive rebuild permits automatic rebuild of failed drives during
normal operation without having to take the array off-line
Automatic error detection/correction of parity errors and bad blocks
Automatic sector re-mapping recovers defective media and corrects data
errors
Supports SAF-TE protocol for integrated monitoring of enclosure power
supplies, fans, and temperature
Each controller in a dual-active configuration monitors the status of its
partner controller
Failure of one controller in a dual-active configuration automatically
initiates a process whereby the surviving controller handles operations for
both controllers
