Introduction to RAID
RAID (Redundant Array of Independent Disks) allows multiple disk drives to be
combined together into a RAID Volume. You create a RAID Volume on your
EdgeStore when you perform the setup procedure, either in the NAS Setup
Wizard or the EASM Setup Wizard.
The benefits of a RAID can include:
•
Higher data transfer rates for increased server performance
•
Increased overall storage capacity for a single Volume
•
Data redundancy/fault tolerance for ensuring continuous system operation in
the event of a disk drive failure
Different RAID levels use different organizational models and have varying
benefits. Also see "Choosing a RAID Level" on page 106. The following outline
breaks down the properties for each RAID level supported on the EdgeStore:
