High Read data transaction rate

Disk failure has a medium impact on

 

 

Medium Write data transaction rate

throughput

 

 

 

 

 

Good aggregate transfer rate

 

 

 

Most versatile RAID level

 

 

 

 

 

 

Recommended applications for RAID 5:

•File and Application servers

•WWW, E-mail, and News servers

•Intranet servers

RAID 10

Advantages

Disadvantages

 

 

Implemented as a mirrored RAID

Very high disk overhead – uses only

Volume whose segments are RAID 0

50% of total capacity

RAID Volumes

 

High I/O rates are achieved thanks to

 

multiple stripe segments

 

 

 

Recommended applications for RAID 10:

•Imaging applications

•Database servers

•General fileserver

Spare Drive

A spare is a disk drive that has been designated to replace a failed disk drive in a RAID Volume. In the event of the failure of a disk drive within a RAID 1 or three- drive RAID 5 Volume, the spare drive is activated as a member of the RAID Volume to replace a disk drive that has failed.

A spare drive cannot replace the failed drive in a RAID 0 Volume because of the way in which data is written to the disk drives under RAID 0.

A spare drive is not available for a RAID 10 Volume because RAID 10 requires all four disk drives in the SmartStor enclosure. However, when you replace the failed disk drive, the SmartStor will automatically rebuild the RAID Volume using the new disk drive.
