c-Class device bay numbers:
Switch port numbers:
As shown in the previous tables, each 3Gb SAS BL Switch is organized in two sets of connections.
These two connection sets are based on the two SAS expanders housed in the switch. Each SAS
expander provides four external SAS ports and is connected internally to eight blade bays. This
design creates the restrictions on configuration best practices.
The VSM interface displays the following warning message if a configuration is attempted that
disregards these recommendations. All such configurations are unsupported by HP.
