Maximum Disk Shelves per Controller Configuration
When determining how many disk shelves a controller configuration supports, it is
important to remember that each disk shelf chain can support up to six disk shelves,
and some controller configurations are limited to a specific number of total disk
shelves. The following table details the number of supported disk shelf chains per HBA
type.

As of software release OS8.7.0, 4x4 port SAS-3 HBAs and 4x4 port SAS-2 HBAs can
be used together in the same system. Controllers cannot simultaneously use 2x4 port
SAS-2 HBAs and 4x4 port SAS-2 HBAs. Sun Disk Shelves are not supported in any
system that includes a SAS-3 HBA, or a combination of SAS-3 and SAS-2 HBAs.
The following table shows the maximum number of HBAs per controller, and the
maximum number of disk shelves supported per controller configuration. Both
standalone and clustered controllers support the same maximum number of disk
shelves.
