Question

A hardware compatibility list recommends striping with double parity as storage for an application. In a test environment, a technician realized that a different RAID level can be used to compensate for a limited number of available disks. Which of the following is the closest RAID level the technician should deploy while minimizing the number of disks and maintaining fault tolerance.

Answer 1

Answer:

RAID level 5 can be used to compensate a limited number of available disks.

Explanation:

There are two type of RAID

• Software RAID
• Hardware RAID

Software RAID

deliver services form the host.

Hardware RAID

provides hardware services.

RAID has levels

0, 1, 5, 6, and 10

RAID 0, 1, and 5 work on both HDD and SSD media,

4 and 6 also work on both media.

RAID 0 :Striping

In this level minimum of two disks,RAID 0 split the file strip the data.Multiple hard drive are used to split the data.

RAID 1 : Mirroring

In this level Minimum two disk require and provide data tendency.

RAID 5 :Stripping with parity

Parity is a binary data.RAID system calculate the value which system used to recover the data.

Most RAID system with parity function store parity blocks.

RAID 5 combines the performance of RAID 0 with redundancy of RAID 1.

RAID 5 level should minimize the fault tolerance.
