RAID Technology - Understanding Disk Arrays

and Virtual Disks

The Dell PowerEdge PERC S110 RAID Controller allows:

• SATA HDD, and/or SATA SSD physical disks to co-exist on a single

controller.

• Physical disks of the same type (SATA HDD, SATA SSD) but of different

capacities.

• Virtual disks to be at different RAID levels on the same controller, but not

supported on the same group of physical disks.

No Read Ahead/Write Through

The PERC S110 uses part of system memory for cache.

recent checkpoint.
