Sun StorEdge 3500 Series Architecture

All members of the StorEdge 3500 series arrays share the same architecture elements.
This section discusses those elements, making note of the few differences in how the
architecture was implemented differently in the StorEdge 3510 FC and 3511 SATA
products.
The Sun StorEdge 3500 series RAID controllers have six FC channels. RAID
controller channels 0, 1, 4, and 5 are normally designated for connection to hosts or
Fibre Channel switches. RAID controller channels 2 and 3 are dedicated drive
channels that connect to disks. Each channel has a single port connection except the
Sun StorEdge 3511 SATA array which has two extra ports (two connections for
channels 0 and 1).
In a dual RAID controller configuration, the architecture of the loops within the
chassis provides both RAID controllers the same host channel designators. Each host
channel of the top RAID controller shares a loop with the matching host channel on
the bottom RAID controller. For example, channel 0 of the top RAID controller
shares the same loop as channel 0 of the bottom RAID controller. This provides four
distinct loops for connectivity. The individual loops provide LUN failover without
causing HBA path failover in the event of a controller failure.
A single RAID controller configuration is slightly different. The lower I/O board has
drive channels but does not have host channels. Overall, the same number of loops
are available, but with only half as many host channel ports.
Sun StorEdge 3510 FC Array. RAID controller channels 0, 1, 4, and 5 are normally
designated host channels. Any of the host channels can be configured as a drive
channel. In a dual controller configuration, each host loop includes two ports per
loop, one port on the top controller and one port on the bottom controller.
