Chapter 1 About the K2 Level 3 RAID storage
NOTE: Once the Level 3 RAID is installed and configured, the disk
modules become slot dependent. Moving disk modules between physical
slots will result in loss of data and the need to reconfigure the system.
Level 3 RAID Circuit board modules
There are two circuit board modules used: the RAID controller module and the
expansion adapter. The RAID controller module is in the primary RAID chassis. It
manages the disk drives and provides a Fibre Channel interface to the K2 Media
Server system or Fibre Channel switch fabric. The expansion adapter is in an
Expansion chassis. It manages the disk drives, in conjunction with the connected
RAID controller and provides a Fibre Channel interface to the primary chassis.
Level 3 RAID Storage Chassis circuit board modules
The K2 Level 3R includes one or two RAID controller modules. This provides
redundant Fiber Channel interface ports.
The following figure shows a K2 Level 3 RAID Storage Chassis with the two RAID
controller modules installed.
