Virtualization Engine Description
The virtualization engine supports the multipathing functionality of the Sun
StorEdge T3+ array. Each virtualization engine has physical access to all underlying
Sun StorEdge T3+ arrays and controls access to half of the Sun StorEdge T3+ arrays.
The virtualization engine has the ability to assume control of all arrays in the event
of component failure. The configuration is maintained between virtualization engine
pairs through redundant T Port connections by way of a pair of Sun StorEdge
network FC switch-8 or switch-16 switches.
