Clustering is a means of sharing array groups among controllers to provide
redundancy of controllers and servers. This redundancy is important if a hardware
component fails. If a hardware component failure occurs in a cluster, another server
takes ownership of the array group.
Clustering requires software specific to your operating system. For more information
about clustering, go to the following Web sites:

After you unpack the storage subsystem, verify that you have the following items:
Hardware
IBM DS4300 storage subsystem comes with the following components:
v RAID controllers:
– 2 controllers on Model 60U/60X
– 1 controller on Model 6LU/6LX
v Power supplies:
– 2 power supplies on Model 60U/60X
– 1 power supply on Model 6LU/6LX
v Power cords:
– Two power cords on Model 60U/60X
RAID controllers
v Technology and interfaces:
– Fibre Channel: 40-pin fibre-channel
disk drives
– Fibre Channel interface:
- For Model 60U/60X, six small
form-factor pluggable (SFP)
modules for incoming and
outgoing fibre-channel cables
(three SFPs on each RAID
controller).
- For Model 6LU/6LX, two SFP
modules for incoming
fibre-channel cables (two SFPs on
the RAID controller).
– Two auto-negotiate 1 Gbps/2 Gbps
fibre-channel host-side connections
per controller
