8 Sun StorEdge T3 and T3+ Array Configuration Guide • August 2001
Configuration Guidelines and
Restrictions
Workgroup Configurations:
■ The media access control (MAC) address is required to assign an IP address to the
controller unit. The MAC address uniquely identifies each node of a network. The
MAC address is available on the pull-out tab on the front left side of the array.
■ A host-based mirroring solution is necessary to protect data in cache.
■ Sun StorEdge T3 array workgroup configurations are supported in Sun Cluster
2.2 environments. Sun StorEdge T3 and T3+ array workgroup configurations are
supported in Sun Cluster 3.0 environments.
Enterprise Configurations
■ Partner groups can be connected to more than one host only if the following
conditions exist:
■ The partner group must be connected to the hosts through a hub.
■ The configuration must be using Sun StorEdge Traffic Manager software for
multipathing support.
■
The configuration must be a cluster configuration using Sun Cluster 3.0
software.
■ You cannot use a daisy-chain configuration to link more than two controller units
together.
■ You can only connect arrays of the same type model in a partner group.
■ In a cluster configuration, partner groups are supported using only Sun Cluster
3.0 software. They are not supported with Sun Cluster 2.2 software.
Caution – In an enterprise configuration, make sure you to use the MAC address of
the master controller unit.
