Server & RAID FAQ – A Short Introduction To RAID Systems
RAID data arrays are crucial for storage, advice and data protection strategies for small companies, large companies and personal computer users with considerable amounts of data to get and save. Almost all modern servers use some sort of RAID technology to save and handle data.
Question: Just what does RAID stand for?
Answer: Initially the “I” stood for Affordable, but nowadays it is become Independent.
Question: And what’s it?
Answer: A RAID array is actually a host of disk drives that are joined to your own pc system or server in such a fashion that every one of the drives work as just one storage component. This really is called data redundancy. Usually, RAID arrays are used as huge file servers which keep and handle data in the event of the hard-drive failure.
Question: What precisely are RAID levels?
Answer: The sort of RAID you select dictates the method the data will probably be saved across all of the disks which compose the set. RAID 0 is also commonly encountered but supplies no redundancy whatsoever, therefore an individual disk failure brings a whole RAID 0 system down. These are able to be fairly slow for writing substantial quantities of data for their drives but on the flip-side, RAID 5 provides a great number of fault tolerance, meaning your data can often be recovered with a data recovery company from many other drives inside the array if just one drive fails for any purpose.
Data is saved using numerous techniques including reflecting, striping and storing parity data. Reflecting is the process of making an exact replica of the block of data and preserving it on two separate hard drives.
Question: What are nested RAID levels?
Answer: Nested RAID levels are mixes of two different RAID configurations providing the benefits of both strategies.
Question: Are the any disadvantages to using RAID?
Answer: Additionally, if you want to enhance your RAID level, you must disassemble the array, back-up your personal data and start over. Some newer systems circumvent these problems, but have constraints in their own. Generally RAID is a strong way of enhancing functioning, storage capacity and data protection.
Question: Where might I get a Server?
Answer: All modern server systems, for your NAS boxes you can purchase within the main street for the company servers offered by HP and Dell are obtainable in a broad selection of RAID configurations.
