Troubleshooting the Sun StorEdge
T3+ Array Devices
The Sun StorEdge T3+ array is a high-performance, modular, scalable storage device
that contains an internal RAID controller and disk drives with FC connectivity to the
data host.
In the Sun StorEdge 3900 and 6900 series, the Sun StorEdge T3+ array is used as a
building block, configured in various ways to provide a storage solution optimized
to the host application. The array is sometimes called a controller unit, which refers to
the internal RAID controller on the controller card. Arrays without the controller
card are called expansion units. When connected to a controller unit, the expansion
unit enables the user to increase storage capacity.
