VA 7400/7410 Redundancy Groups
The VA 7400 and VA 7410 have two redundancy groups (RG1 and RG2). See
Figure 15
and
Figure 16
.
■
Controller 1 manages Redundancy Group 1 (RG1), which consists of all
disks in odd numbered slots (D1, D3, D5, D7, D9, D11, D13, D15) in the
controller enclosure, and in all disk enclosures (JA0-JA5).
■
Controller 2 manages Redundancy Group 2 (RG2), which consists of all
disks in even numbered slots (D2, D4, D6, D8, D10, D12, D14) in the
controller enclosure, and in all disk enclosures (JA0-JA5).
On the VA 7410, Redundancy Group are independent of both back-end FC
loops. Management of the redundancy group disks is independent of which
disk enclosure LCC the array controller is connected to. For example, array
controller 1 can be connected to LCC 1 or LCC 2 and it will still manage the
disks in the odd numbered slots.
The array controllers are connected via an internal N-Way bus, which used for
controller-to-controller communication and loop failover.
