Chassis
The following figure shows the RAID Storage Chassis components. Details on each
component follow the figure.
NOTE: Every K2 Lx0 RAID chassis controller includes a backup battery so that if
electrical power is lost, data stored in cache memory will be saved.
Chassis
The chassis is a sheet-metal housing that contains chassis slots for the RAID
controllers or expansion adapters, disk drives, power supplies, and the LAN card.
K2 Lx0 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 an interface to the K2 Media Server system or
switch. The expansion adapter is in an Expansion chassis. It manages the disk drives,
in conjunction with the connected RAID controller and provides an SAS interface to
the primary chassis.
K2 Lx0 RAID Storage Chassis circuit board modules
The K2 Lx0 RAID includes one or two RAID controller modules. This provides
redundant host interface ports.
