4.5 RAID Functions
RAID Denions
In a RAID 0 system data are split up in blocks that get
wrien across all the drives in the array. By using mulple
disks (at least 2) at the same me, this oers superior I/O
performance. This performance can be enhanced further by
using mulple controllers, ideally one controller per disk.
Features and Benets
• Drives: Minimum 2, and maximum is up to 6 or 8. Depending on the plaorm.
• Uses: Intended for non-crical data requiring high data throughput, or any environment
that does not require fault tolerance.
• Benets: provides increased data throughput, especially for large les. No capacity loss
penalty for parity.
• Drawbacks: Does not deliver any fault tolerance. If any drive in the array fails, all data is
lost.
• Fault Tolerance: No.
• Total Capacity: (Minimal. HDD Capacity) x (Connected HDDs Amount)
Data are stored twice by wring them to both the data disk
(or set of data disks) and a mirror disk (or set of disks) . If
a disk fails, the controller uses either the data drive or the
mirror drive for data recovery and connues operaon. You
need at least 2 disks for a RAID 1 array.
Features and Benets
• Drives: Minimum 2, and maximum is 2.
• Uses: RAID 1 is ideal for small databases or any other applicaon that requires fault
tolerance and minimal capacity.
• Benets: Provides 100% data redundancy. Should one drive fail, the controller switches
to the other drive.
• Drawbacks: Requires 2 drives for the storage space of one drive. Performance is impaired
during drive rebuilds.
• Fault Tolerance: Yes.
