Maintaining the Sun Blade Storage Module M2
The following illustration shows a block diagram of the Sun Blade Storage Module M2 components.
The storage module components include:
Support for up to eight front accessible SAS-2 hard disk drives. For a list of supported drives, refer to the Maintaining the Sun Blade Storage Module M2 in Sun Blade Storage Module M2 Service Manual.
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.
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. For more information, refer to the Assigning Storage to Hosts in Sun Blade Storage Module M2 Administration Guide.
Note - The storage module does not contain a Service Processor. The chassis CMM monitors the storage module and assigns host-to-storage access within the chassis SAS-2 domain.
