Media RAID
The Media RAID array consist of two parts: the RAID
array itself comprising 16 hard disk drives (HDDs) for
storage, and a RAID controller card mounted on the
motherboard.
The Media RAID array is arranged in four rows. Each row
comprises 4 HDDs. Data is simultaneously written to two
disks, this allows continued operation and full recovery of
data when a single disk fails. The HDDs are hot-
swappable, and therefore can be removed while the unit is
still operational (see
“Media RAID HDD replacement” on
page 84 ).
The RAID controller stores certain configuration
parameters on a reserved area of each disk drive called the
Drive Configuration Block (DCB). disk configuration
block. This is 3ware proprietary RAID table information
that is written to disk drives that are in a RAID unit. The
DCB includes information on the unit type, unit members,
RAID level, and other important RAID information.
HDDs are numbered according to the illustration below. If
multiple drives are removed for any reason, they must be
returned to their original positions. Failure to do this will
result in unrecoverable loss of media.
Failure or degraded operation can be alerted to an operator
using Windows Messenger to a nominated client PC. See
the
HDXC-C030 HDXC-B030 HDXC-X030 HDXC-L030
Installation Manual for details of the Windows Messenger
service. The manual also describes how to access the web
page associated with the RAID controller cards. The web
page should be used to identify faulty drives, and
administration of their replacement.
When the server has booted up, all (16) of the blue ON/
ACTIVITY LEDs should be ON to indicate that the RAID
array is functioning correctly.
