Configuring Your System 3-29
Optional RAID Controllers
Factory Installed Controllers
The RAID options available for your system is the Mylex AcceleRAID
™
150
(SecuRAID 110) Controller board, which gives your system the added security of fault
tolerance.
If you order a system with a RAID controller, the system is pre-configured at the
factory. Refer to the “RAID Configurations” table below to determine how the RAID
controller was configured at the factory. If you want to reconfigure disk arrays and
logical drives, you must run the AcceleRAID
™
150 BIOS Configuration Utility; if you
want to change the RAID level, you must run the Mylex Disk Array Controller Utilities
(DACCF) software. Refer to the AcceleRAID
™
150 documentation included with your
system for information on running the AcceleRAID
™
150 BIOS Configuration Utility
and the DACCF utility.
CAUTION
Some server systems have network operating systems preloaded at
the factory. If a network operating system is preloaded on your
server system, then use of the DACCF utility is not required.
However, if you do use the DACCF utility you may need to reload the
network operating system. Make sure that you have all the pertinent
software to perform the reload.

JBOD
1
JBOD (RAID 0) JBOD is an acronym for Just a Bunch Of
Disks. Each drive can operate independently as with a
common host bus adapter; or multiple drives may be spanned
and seen as a single very large drive. No redundancy is
provided.

Mirroring (RAID 1) Drives are paired and mirrored. All data is
100% duplicated on an equivalent drive (fully redundant).

Striping with Parity (RAID 5) Data is striped across several
physical drives. Parity protection is used for data redundancy.

spare drive
Striping with Parity (RAID 5) Data is striped across three
physical drives. Parity protection is used for data redundancy.
This drive is used as the “Hot Spare.”
