Which one of the following provides a fault-tolerant storage system
containing five disks and a
single controller that will function if a single disk fails?
A. A striped set array without parity
B. A RAID 10 (Redundant Array of Independent Disks) array
C. A striped set array with parity
D. A duplexed RAID 01 (Redundant Array of Independent Disks)
Answer: B
:The most popular of the multiple RAID levels, RAID 01 and 10 combine
the best features of striping
and mirroring to yield large arrays with high performance in most uses
and superior fault tolerance.
RAID 01 is a mirrored configuration of two striped sets; RAID 10 is a
stripe across a number of
mirrored sets. RAID 10 and 01 have been increasing dramatically in
popularity as hard disks become
cheaper and the four-drive minimum is legitimately seen as much less
of an obstacle. RAID 10 provides
better fault tolerance and rebuild performance than RAID 01. Both
array types provide very good to
excellent overall performance by combining the speed of RAID 0 with
the redundancy of RAID 1
without requiring parity calculations.
Hard Disk Requirements: An even number of hard disks with a minimum of
four; maximum
dependent on controller. All drives should be identical.
