The storage module components include:
Support for up to eight front accessible SAS-2 hard disk drives. For a list of supported disks, refer to Options and Replaceable Components.
Two internal LSI SAS–2 x36 expanders, which are crossbar switches that connect SAS devices, such as HBAs and drives. These expanders provide dual paths to each SAS device in the storage module. For dual path support, two SAS-2 NEMs must be installed in the chassis.
A World Wide Name (WWN) on the serial label and in firmware which acts as a unique identifier for the storage module. This is also known as the SAS address for the module.
Note - There are also a serial labels on the top and bottom of the storage module (viewable when the module is out of the chassis), and on one of the module ejectors (viewable from the front when the module is in the chassis).
Storage resources that can be divided among multiple server hosts. This assigning of resources per host is called SAS-2 zoning and is configured through the chassis CMM ILOM.
Note - The storage module does not contain a Service Processor. The chassis CMM monitors the storage module. Assigning host-to-storage access within the chassis SAS-2 domain is done through the Sun Blade Zone Manager feature of the CMM ILOM.
