32 Sun StorEdge T3 and T3+ Array Configuration Guide • August 2001

Single Host With Eight Controller Units

Configured as Four Partner Groups

FIGURE 4-5 shows one application host connected through FC-AL cables to eight Sun

StorEdge T3+ arrays, forming four partner groups. This configuration is the

maximum allowed in a 72-inch cabinet. This configuration can be used for footprint

and I/O throughput.

Note – This configuration is a recommended enterprise configuration for RAS

functionality because the controller is not a single point of failure.

The following three parameters must be set on the master controller unit, as follows:

■ mp_support = rw or mpxio

■ cache mode = auto

■ cache mirroring = auto

Note – For information on setting these parameters, refer to the Sun StorEdge T3 and

T3+ Array Administrator’s Guide.

Host-based multipathing software is required for this configuration.
