Introduction
Thank you for purchasing your new ArrayMasStor K-Series RAID system from ADTX
¨
. This
high quality data storage system offers very high performance with Òstate-of-the-artÓ reliability. It
has been rigorously tested to ensure trouble-free operation and long life.
The K-Series is a SCSI-to-IDE RAID system with drive bay space for six EIDE disk drives. The
system can be used with virtually all contemporary SCSI equipped host systems.
As a RAID data storage system, it provides both increased drive access speed and fault tolerance
(i.e., one drive in the system can fail without affecting its data integrity or operations). The system
provides additional fault tolerance with dual, redundant, hot-swappable fan/indicator modules and
power supplies. All of its RAID functions are performed by a PowerPC
Ò
RISC CPU with high-
speed SDRAM and flash memory firmware.
Its built-in hardware RAID controller employs sophisticated drive failure management capabilities
that allow automatic reassignment of reserved blocks when a bad drive sector is encountered during
write operations. Hot swapping of the drives is supported through automatic disconnection of a
failed drive and the automatic detection of a spare ÒreservedÓ drive. If a drive fails, the system
supports the automatic rebuilding of data in the background, allowing host operations to continue.
Amazingly, failure recovery operations are completely transparent to the host system.
The K-Series system is so easy to use, that it can be installed, configured, and deployed by users
without intimate knowledge of RAID systems. ItÕs built-in automatic RAID setup feature can
perform all of the setup, ID assignment, and configuration tasks needed for regular operation.
