You are implementing a RAID storage system and have found a system with eight 100 GB drives. How much storage space will you hav

asambeis [7]

Answer:

The space available will vary between 800 GB (100%) and 400 GB (50%) of the total disks, depending on the RAID level.

The OS will handle the RAID as a single disk.

Explanation:

Each RAID level implements parity and redundancy in a different way, so the amount of disks used for this extra information will reduce the space available for actual storage.

Usual RAID levels are:

RAID 0: does not implement any redundancy or parity, so you will have available 100% of the total storage: 8 x 100 GB = 800 GB

RAID 1: Duplicates all the information in one disk to a second disk. Space is reduced in half: 400 GB

RAID 5: Uses the equivalent of 1 disk of parity data distributed evenly on each disk, meaning the space available is $\frac{n-1}{n}$ of the total disks: $\frac{7}{8}$ of 800 GB = 700 GB

Writting and reading the information on a RAID storage is handled by a raid controller, either implemented in hardware or software. The OS will "see" a single disk and will read or write information as usual.

}

Explanation:

Inside the action performed method, pass the strings in text box.
check if the value has been modified then do the relevant conversions inside the conditional statement.
When the user clears, it will not do to the inch conversion.
