To set up a multipath enclosure on the PERC H965e card:
On the controller, port 0 and 1, or port 2 and 3 must be used together. Interleaving of controller ports for multipath configuration is not supported.
To connect a single enclosure, cable the ports so that the enclosure is connected to port 0 and 1, or port 2 and 3 on the controller card.
To connect multiple enclosures, connect a set of ports on the controller to the first enclosure as mentioned in the above bullet point. Connect cables from the first enclosure to the second enclosure. Then, continue to connect 2 cables from the last enclosure in the chain to the next enclosure you want to include until you have up to 4 enclosures, or 8 enclosures with 4 enclosures per stack. See Figure 6 and Figure 7.
NOTE:The PERC H965e adapter card can detect and use redundant paths to disks contained in the enclosures. With redundant paths to the same device, if one path fails, another path can be used to communicate between the controller and the device.
NOTE:Max enclosure support for multipath: Eight (8) MD2412 and MD2424 enclosures or four (4) MD2460 enclosures.
NOTE:It is recommended that the wait-time for hot-removing or hot-inserting enclosure data or power cables is 2-3 minutes for 24 drives in a single MD24xx series disk-attached storage enclosure and up to five minutes for maximum enclosures configuration.
