44 Sun StorEdge T3 and T3+ Array Configuration Guide August 2001
Dual Hosts With Two Hubs and Eight Controller
Units Configured as Four Partner Groups
FIGURE 4-9 shows two application hosts connected through FC-AL cables to two hubs
and eight Sun StorEdge T3+ arrays forming four partner groups. This multi-initiator
configuration can be used for footprint and I/O throughput.
This configuration is a recommended enterprise configuration for RAS functionality
because the controller is not a single point of failure.
Note – There are no hub port position dependencies when connecting Sun StorEdge
T3 and T3+ arrays to a hub. An array can be connected to any available port on the
hub.
When configuring more than one partner group or a single array to share a single
FC-AL loop, as with a hub, array target addresses need to be set to unique values.
Assign the array target address using the port set command. These target
addresses can be any number between 1 and 125. At the factory, the array target
addresses are set starting with target address 1 for the bottom array and continuing
to the top array. Use the port list command to verify that all arrays have a
unique target address. Refer to Appendix A of the Sun StorEdge T3 and T3+ Array
Administrators Guide for further details.
The following two 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 Administrators Guide
Host-based multipathing software is required for this configuration.
