Question No. 4

A customer has experienced a high rate of drive failure and loss of data in its environment and is considering IBM XIV to replace the existing storage.

Which IBM XIV benefit should the technical specialist hightlight to the customer?

Show Answer Hide Answer
Correct Answer: B

When an IBM XIV disk fails, all disks in the system participate in the rebuild. The outcome? It takes less time for theXIV system to restore full redundancy. For example, if a disk on a fully used 1 TB drive system fails, XIV restores full redundancy in an average of 30 minutes or less, and without a significant performance penalty. Traditional RAID systems might take up to a day to restore data reliability, with performance compromised during rebuild. The fast XIV rebuild time means that your data spends less time that is exposed to risk. In this way, the XIV system actually protects your data more than traditional enterprise storage systems can.
