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.
RAID Controller Features of the PERC S110
Adapter
Boot Support for Degraded Virtual Disks
Enables the system to boot from degraded redundant virtual disks (RAID 1,
RAID 5, or RAID 10).
Cache Support for Virtual Disks
Supports these cache options:
Read Ahead/Write Back
No Read Ahead/Write Back
Read Ahead/Write Through
No Read Ahead/Write Through
.
The PERC S110 uses part of system memory for cache.
Checkpointing
Allows different types of checkpointing (background initialization,
consistency check, and rebuild) to resume at the last point following a restart.
After the system restarts, background checkpointing resumes at its most-
recent checkpoint.
