ServeRAID-MR10M SAS/SATA Controller Characteristics

 

3.3.3

Fault Tolerance

Table 3.5

 shows the fault tolerance features of the ServeRAID-MR10M 

SAS/SATA Controller.

3.3.4

Power Supply Requirements for the ServeRAID-MR10M 
Controller

All power is supplied to the ServeRAID-MR10M SAS/SATA Controller 
through the PCI Express 3.3V rails and the 12V rail. Onboard switching 
regulator circuitry operating from the 3.3V rails and the 12V rail provide 
the necessary voltages. The following states determine the typical 
current consumption of the controller:

•

State 1: During a hard reset

•

State 2: During a disk stress test

Stripe Sizes

8, 16, 32, 64, or 128 Kbyte

Maximum Number of Concurrent 

Commands

255

Support for Multiple Initiators

Yes
