RAID-800S User's Manual
1.1 Introduction
The RAID-800S is a SCSI-to-SCSI RAID (Redundant Arrays of Indepen-
dent Disks) Disk Array subsystem. A disk array is two or more disks
grouped together to appear as a single disk to the host system.
This “Host Independent” RAID subsystem supports RAID level 0, 1,
0+1, 3 and 5 which provide improved data availability and reliability.
Regardless of the RAID level your subsystem is configured, each RAID
array consists of a set of disks which to the user appears to be a single
large disk capacity.
One unique feature of these RAID levels is that data are spread across
separate disks as a result from the redundant manner in which data is
stored in a RAID disk array. If a disk in the RAID array fails, your
subsystem continues to function without any risk of data loss. This is
because redundant information are stored separate from the data. These
redundant information will then be used to reconstruct any data that
was stored on a failed disk. In other words, your subsystem can tolerate
the failure of a drive without losing data and operates independently of
each other.
The RAID-800S Ultra Wide SCSI subsystem allows very fast 40 Mbps
transfer rate using a 16-bit SCSI bus thus providing faster data input
and output. It supports a wide range of brands, capacities, models and
access time hard disk drives. Its modular design allows hot-swapping of
hard drives without interrupting subsystem operation.
