Raid concept - How to deal with RAID concepts in interview persective?
Raid concept - How to deal with RAID concepts from an interview perspective?
RAID (Redundant Array of
Independent Disks)
RAID 0 - RAID 1 -
RAID 5 - RAID 10
RAID 0 (Striping)
==============
Not fault tolerance
Data is striped across multiple
disks
The data will be lost if one of
the disk got corruped/destroyed.
RAID 1 (Mirroring and Duplexing)
============================
Fault tolerant
Data is copied on more than one
disk
Each disk has the same data
(data is safe)
RAID 5 (Striping with parity)
======================
Requires 3 or more disks
commonly used and It can store
large amount of data and raid 5 is fast
Data is 'striped' across
multiple disks along with parity (Parity is used to rebuild the data in the
event of disk failure.)
RAID 10 (RAID 1+0)
==================
Combines Raid 1 and Raid 0
Need to use minimum of 4 disks
Two disks is mirrored using raid
1 setup (Both sets of 2 disks are striped using raid 0 setup)
Benefits from the fault
tolerance of raid 1 and speed of raid 0
The disadvantage is - can only use
50% for data storage
(BTW, Fault tolerance refers to the ability of a system (computer, network, cloud cluster, etc.) to continue
operating without interruption when one or more of its components fail.)
