RAID – Just a Bunch of Disks

The RAID is nothing but a simple combination of the several storage media. The storage media are necessarily the hard disk drives that are used for the storage of the data. The technology and the implementation of RAID are quite useful for the servers. The disk drives used for the purpose of the implementation of the [...]

Software Vs Hardware RAID

Software RAID:

There are some disadvantages in implementing RAID in software. First of all the problem is with portability. Since a software implementation will definitely have Operating System specific components, these components should have to be rewritten for each Operating System to be functional. The second major problem is that it uses kernel mode software developers. Unlike [...]

Hardware RAID by a controller

The physical implementation of the RAID is almost similar to the implementation of any other normal computer. The RAID may not be essentially any hardware that is used for [...]

Redundant Array of Independent Disks – RAID

The abbreviation for the RAID is Redundant Array of Independent Disks. This RAID by definition stands for the subsystem for the disks. The expectation for using this is the increment in the performance and the value added [...]

Possible approaches to RAID

Hardware RAID

The hardware based system manages the RAID subsystem independently from the host and presents to the host only a single disk per RAID array. This way the host doesn’t have to [...]

The different RAID levels

RAID-0
RAID Level 0 is not redundant, hence does not truly fit the “RAID” acronym. In level 0, data is split across drives, resulting in higher data throughput. Since no redundant information [...]

What is RAID

What does RAID stand for ?

In 1987, Patterson, Gibson and Katz at the University of California Berkeley, published a paper entitled “A Case for Redundant Arrays [...]
