RAID Striping

Better protection and performance

• Circumvents drive failures
• Spreads I/O across multiple spindles
• Off loads RAID 0 & 1
• Supports popular RAID devices in pool

RAID (or Redundant Arrays of Inexpensive Disks) is a common way to gain better performance and protection by spreading I/O’s across multiple disk spindles. Virtual disks may be intentionally striped across several physical drives or simply mapped to a logical RAID drive supplied by the underlying disk subsystems.

Thin provisioning takes advantage of striping to dynamically allocate more disk space when the initial set of drives runs out of room.
