Raid and Server Technology Information

What is RAID?

RAID (Redundant array of independent of independent disks) in simple terms it is information storing virtualization machinery that encompasess several physical disk drive parts into one logical unit.


The main principle behind RAID was initially mentioned by the co-founders of Geac Computer Corporation; who are Gus German, and Ted Grunau. Who called it MF-100.It was later related to RAID after an invention of The term “RAID” was developed by David Patterson, Garth A. Gibson and Randy Katz.

Types of RAID

  • RAID 1; It entails information mirroring, without equality or striping. Information is written identically to two drives hence producing a “mirrored set.”
  • RAID 2; It comprises of bit-level strips with committed Hamming-code equality. All plate shaft pivot is synchronized, and The information is striped with The end goal that each successive piece is on an alternate drive.
  • RAID 3; it entails of byte-level strips with dedicated parity.
  • RAID 4; it entails a block level strips with dedicated parity.
  • RAID 5; This consist of block strips with distributed parity. But unlike the forth, uniformity information is spread among all drives such no data is lost upon failure of a single disc.
  • RAID 6; Consist of block strips with paired spread equality.

Functions of RAID

When used In conjunction with each one another, it delivers extra data protection from system threats derived from malicious users and accidental deletion or viruses. It also allows a system administrator to create a secure back-up of The active data-array.

What is a server?

The server is simply a program that provides services to other Computer programs. The machine that a server program runs is also frequently known to as The server.

Server types

  • Dedicated server; a machine that a server program regularly runs.
  • Client server; these are an application server that awaits and fulfills requests from client programs.
  • Web server; these are software that serves requested HTML pages or files.
  • Proxy server; This is a product that goes about as a middle person between an endpoint device, for instance, a PC and another server from which a customer or client is inquiring service.
  • Mail server; it’s an application that receives an incoming e-mail from local users.
  • Practical server; is a program running on a shared server.
  • Blade server; It’s a server chassis housing several thin, modular electronic circuit board known as ‘server blades.’
  • File server; This is a machine responsible for The central storage and management of data files.
  • Policy server; This is a security component of a policy based network that provides authorization services and facilitates tracking and control of files.

Functions of server

The duties of The server are spelled out clearly on The various types of The servers and their specific functions.

What is The relation between RAID and Server?

RAID is mainly used for storage and backup In a program while a server primarily participates In receiving information. The two programs serve important roles that are very helpful. With servers, RAID can bring more benefits and functions efficiently. A server-based RAID can have either software based or operating system based functionality. This correlation is executed In a storing system via a storing controller which is also known as RAID controller.

Any user of The two programs can note The benefits while In use and their downsides. Acquiring information on how to upgrade their functionality could help or look for The newest updated versions of The programs would assist to avoid frustrations or other problems that could originate from The program.
