Redundant and Non-Redundant Configurations

Non-redundant configurations are configurations that provide only a single

data path from a host to the storage array. This type of configuration is only

recommended for non-critical data storage. Path failure from a failed or

removed cable, a failed HBA, or a failed or removed RAID controller module

results in loss of host access to storage on the storage array.

Redundancy is established by installing separate data paths between the host

and the storage array, in which each path is set to one of the two RAID

controller modules installed in the storage array. Redundancy protects the

host from losing access to data in the event of path failure, because both

RAID controller modules can access all the disks in the storage array.

Figure 2-1 through Figure 2-3 show two and four hosts, each connected to

only one RAID controller module. The hosts can share storage space but

without redundant paths, if one path were to fail, the server on that path

would be disconnected from the storage array.
