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. For information
on disk compatibility, see the Oracle Systems Handbook.
