Cluster Storage

Table 1-5 lists supported storage systems and the configuration requirements

for the cluster nodes and stand-alone systems connected to the storage

systems.

Cluster shared

storage

If you are using either switch modules or pass-through

modules to connect to network storage devices that are

attached to external switches in a SAN or an IP SAN, see the

Dell Cluster Configuration Support Matrix at dell.com/ha to

determine the maximum number of supported storage

systems.

If you are using fibre channel modules to connect to storage

devices without external fibre channel switches, you can use a

maximum of two supported storage systems.

You can use a maximum of four supported storage systems if

you are using:

• fibre channel (switch or pass-through) modules connected to

external fibre channel switches

• Ethernet switch modules to connect to storage devices

If you are using pass-through modules to connect to storage

devices in a direct-attached configuration, you can use a single

supported storage system.

Multiple clusters

and stand-alone

systems

Storage systems that provide LUN masking or assignment

functionality may be shared between multiple clusters or

between clustered and stand-alone servers. To determine

whether the configuration is supported, see the Dell Cluster

Configuration Support Matrix at dell.com/ha.
