Cabling RAID Configurations

Dual RAID
Controller to Host
Configuration
Note: For dual RAID enclosures there must be two LS
modules installed in the enclosure.
This section describes the procedure for connecting an
enclosure with dual RAID Controllers (redundant
controllers) to your host system.
It is also possible to use this configuration as two RAIDs
(i.e. non-redundant controllers). In this configuraion the
dual drive loops are shared between the RAID systems.
To connect the dual RAID controller enclosure to your
host system:
Note: You will need two HBAs in your host system or a single HBA
with support for two connections. A hub, switch or 2 hosts with HBA
may also be used.
1 Insert the DB9 connector on the first cable, into the DB9
connector on the first RAID controller (see Figure 3-9).
2 Insert the other end of this cable into the connector on your
HBA.
3 Insert the DB9 connector on the second cable, into the DB9
connector on the second RAID controller (see Figure 3-9).
4 Insert the other end of this cable into the connector on your
HBA.
