K2 Level 2 RAID Circuit board modules
The disk drives are 3.5-inch FC-AL drives that conform to the Fibre Channel
Arbitrated Loop (FC-AL) standards and support dual-port FC-AL interconnects
through the two RAID controllers and their cabling.
NOTE: Once the K2 Level 2 External 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.
K2 Level 2 RAID Circuit board modules
There are three circuit board modules used: the RAID controller module, the
expansion adapter, and the LAN card. 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. The LAN card is in the primary RAID chassis only. It provides an Ethernet
port for NetCentral monitoring, a shutdown switch, and signal connections for an
uninterruptive power supply (UPS).
K2 Level 2 RAID RAID Storage Chassis circuit board modules
The K2 Level 2R includes one or two RAID controller modules. This provides
redundant Fiber Channel interface ports.
The following figure shows a K2 Level 2 RAID RAID Storage Chassis with the two
RAID controller modules installed.
