RAID-800S User's Manual
up to eight LUNs per drive group. For example, the third logical unit on
a drive channel with SCSI ID 1 will be read by the hosts computer as ID
1 LUN 2.
Use the controller’s LCD panel or the terminal connected to the serial
monitor port to configure the logical units of a drive group.
2.9 RAID Management
The subsystem implements different versions of the RAID (Redundant
Array of Independent Disk) technology. Each version is commonly
refered to as RAID level and is selected when the logical units are
defined and created based on the following:
- disk capacity
- data availability (fault tolerance or redundancy)
- disk performance
The subsystem supports RAID levels 0, 1, 0+1, 3 and 5. RAID imple-
mentation and the disk drives’ physical configuration is transparent to
the host operating system. This means that the host operating system
drivers and software utilities are not in any way affected by any RAID
level.
To properly configure the subsystem, a proper understanding of the
RAID technology is an advantage. This concept is described in detail in
Appendix A of this manual.
2.10 Drive Management
2.10.1 Hot-Swap Drive Replacement
The subsystem supports hot-swapping of drives while the system is on.
A disk may be disconnected, removed or replaced with a different disk
without turning off the system. The SCSI bus termination must be
arranged so that a drive can be removed without disrupting the termina-
tion scheme.
