Chapter 1 About the K2 Lx0 RAID
The following figure shows a K2 Lx0 RAID with the two RAID controller modules.
The RAID controller module has two host ports (HP0/HP1) and two Expansion
Chassis SAS ports (DL1/DL0). The Host ports require LCC cables (optical) for the
Fibre Channel connection to a K2 Media Server or to a Fibre Channel switch. The
Expansion Chassis Ports require SAS cables
for the SAS connections with a K2 Lx0
Expansion Chassis. There are two port status LEDs for each Host port and each SAS
port. Refer to
“Interpreting controller status LEDs” on page 35 .
When the redundant controller option is not installed in the K2 Lx0 RAID Storage
Chassis, a blank fills the other RAID controller slot.
K2 Lx0 Expansion RAID Expansion Chassis circuit board modules
The K2 Lx0 Expansion RAID Expansion Chassis has two expansion adapters as
shown in the following figure.
The expansion adapter in the K2 Lx0 Expansion has two SAS ports: DP-IN and
DP-OUT. SAS cabling connects the DP-IN port to a K2 Lx0. There are two port status
LEDs for each SAS port. Refer to
“Interpreting expansion adapter status LEDs” on
page 38 .
