What is RAID
In this post, we are able to try and explain the principles of RAID technology, broadly used for crucial records operations, where not an unmarried little bit of information can be misplaced because of factors together with mechanical or electrical screw-ups in garage disks.
As we recognize, for companies or professionals,
the loss of data can suggest brilliant damages. RAID era, already consolidated
and used for some years, is a very efficient way of shielding records and,
within the case of companies, making certain the permanence in their business.
From this point, we can recognize the standards of this era.
What is RAID?
RAID is the acronym for " Redundant Array of
Independent Disks. " Its definition in Spanish would be "Redundant
Matrix of Independent Disks". It is an era that mixes numerous tough disks
(HD) to form a single logical unit in which equal facts are saved on all disks
(redundancy). In different words, it is hard and fast hard drives that feature
as one.
This type of implementation lets in to have an
excessive tolerance *& in opposition to screw-ups because if one disk has issues,
the others retain to feature, with the person having the statistics at his
disposal as though nothing occurred. The RAID era has been mounted for decades,
having emerged from the University of Berkeley in California (USA) in the late
1980s.
To make up the RAID, you must use at least two
tough drives. The working machine, in this case, will blend the disks as an
unmarried logical power. When facts are recorded, it's far disbursed most of
the RAID disks, constantly depending on the level of RAID adopted, as we will
see underneath.
By implementing RAID, similarly to making sure
records availability in the event of a disk failure, it's also possible to
balance get entry to information so that there aren't any " bottlenecks.
"
RAID levels
RAID technology works in several ways. These are known as "RAID levels." In total, there are six basic levels
