No Fault Tolerance (RAID 0)

RAID 0 does not provide fault tolerance. This level of RAID stripes data across

all the drives in the array, but it does not incorporate a method to create

redundant data. Therefore, if you choose this RAID option for any of your

logical drives, you will experience data loss for that logical drive if one physical

drive fails.

However, because none of the capacity of the logical drives is used for

redundant data, RAID 0 offers the best processing speed and capacity. For this

reason, you may consider assigning RAID 0 to drives that require large capacity

and high speed but do not contain critical data.

Before choosing the RAID 0 option, consider the following:

■ Disk failure will result in data loss for all RAID 0 logical drives.

■ You cannot assign an online spare to an array containing a RAID 0

logical drive.

Online Spare

During configuration, consider assigning an online spare to further improve

your system’s fault tolerance. An online spare (sometimes called a hot-spare) is

a drive the controller uses when a drive failure occurs. If a drive fails, the

controller rebuilds the data that was on the failed drive onto the online spare.

The controller also sends data that it would normally store on the failed drive

directly to the online spare.

The online spare improves the overall system fault tolerance by automatically

replacing a failed drive and quickly restoring the system to full RAID fault-

tolerance protection. During the time the system is operating in the interim

recovery mode with the failed drive, the system is vulnerable to an additional

drive failure.

You can install up to four online spares for each Smart Array 3200 Controller.

To provide an online spare, you must have at least one installed but unassigned

physical drive and the system must be running some type of fault-tolerance

method (RAID 1, RAID 4, or RAID 5).

Spare drives are assigned automatically to all volumes in an array and can be

assigned to multiple arrays connected to the same controller.
