Table 0-4: RAIDWatch Module Requirements
1.3.2 Stand-alone (on Host) Installation
Main features of the RAID-based installation method are listed
below:
• RAIDWatch main programs and the RAID agents used to
communicate with a RAID subsystem over in-band
connection are installed.
• RAIDWatch runs on the RAID-attached server as a Java
program.
1.3.3 Stand-alone (on Subsystem) Installation
Main features of the RAID-based installation method are listed
below:
• RAIDWatch revisions 2.0 and above support installation
to array hard drives. A portion of the drive capacity
(256MB of disk space) is segregated and formatted on
each hard drive. This segregated portion is called a
“reserved space.” Once installation begins, RAIDWatch’s
main programs are automatically distributed to the
reserved space.
