RAID – Redundant Array of Inexpensive DISK tutorials

 

SPANNED

Strip set

 

RAID 0

Mirror

 

RAID 1

Strip set with parity RAID

(5)

RAID 10

MIRROR + STRIP SET

 

is a dynamic volume that content space from one disk upto 32 disk. It write data on one disk till it is full, then it write to other

No fault tolerant & No data redundancy It spreads data in blocks across multiple disks, better Performance. if one disk fails, all data is lost.

disk mirroring, all data is duplicated or ‘written to' a second hard disk. If one of the disks fails, the data still available on the second disk. Full fault tolerant

excellent fault tolerance & good performance. It stores parity information across all disks in the disk array and provides concurrent disk reads & writes

It starts as Mirror RAID-1 of 2 disks. Additional mirrors are added and then striped RAID 0. For each addition of disk, it must be added as PAIR of disk as mirror.

Spanned Volume

 

  • Spanned Volume is a dynamic volume that content space from Two disk upto 32 disk.

  • It writes data on one disk till it is full then it writes to other disk.

  • It gathers free space from many disks and allocates one Volume name.

  • You can create a spanned volume either by extending a simple volume to unallocated space from second disk & multiple disks.

  • There is no fault Tolerance.

  • You can shrink a spanned volume without losing data. In such a case number of disks involved may decrease.

  • You can extend a spanned volume maximum upto 32 disk, include unallocated areas from all disk and this way you can extend Capacity of volume.

  • As you notice in this example of spanned volume, all data is written on disk zero, that is data block number from 1 to 10, after space on disk drive 0 is full, it write data on second disk i.e. disk 1.

  • Biggest Drawback:- There is No Fault Tolerance for Spanned Volumes . Remember that from combine group of any disk, if any disk fail, All Data on Whole Volume could be lost.

  • Personally, I will never recommend implementation of Spanned Volume in live production, without considering Proper data backup and disaster recovery plan.

 

Striped Volume – RAID 0

  • RAID stands for Redundant Array of Independent Disks, originally Redundant Array of Inexpensive Disks

  • Striped Volume is also known as RAID 0 or Strip set without Parity.

  • A striped volume combines unallocated area from multiple hard disks from 2 to 32 into one volume.

  • Data is written alternately on each disk. So first block is written on 0th disk, 2nd on 1st disk, 3rd block on 0th disk and 4th on 1st disk.

  • It provides improved and faster performance for Reading and Writing, by distributing I/O across all disks configured as part of one set.

  • There is no Fault Tolerance.

  • You can delete a striped volume, but you can’t Shrink or Extend volume.

  • Biggest Drawback:- There is No Fault Tolerance for Striped Volumes . Remember that from combine group of any disk, if any disk fail, All Data on Whole Volume will be lost.

  • Striped volume could be used for PAGEFILE.SYS, it gives improved performance. While implementation of Striped volume in live production for data, consider your plan well in advance for proper data backup and disaster recovery.
