How RAID (Redundant Array of Inexpensive Magnetic Disks) Works

Tags:
raid,
disk,
disks,
parity

Overview RAID is a method of making magnetic disks fault tolerant. RAID uses an ECC (Error Correcting Code), know as Parity, to recover from single point of failure errors. That is, the failure of a single magnetic disk.

RAID commonly uses from 3 to 7 magnetic disks. One of the magnetic disks is used for the parity information, and is not available for storing data. (In this example, the disks are numbered 1 through 5 with 5 being the parity disk).

Quocirca's Straight Talking: Storage meets business

If so, high-value data could be stored on top-end disks, low-value data on low-end tapes, and so on. Spawned from the idea that there is more to storing data than, well, storage, the thinkers set about making it work better.

EMC rewinds on tape stance

When it comes to storing data, disks just aren't enough anymore, EMC claimed this week. The maker of disk-based storage systems announced that it will resell tape-based devices from Advanced Digital Information as a way of giving customers a less...

Longhorn Server will 'fix itself on the fly'

The system can fix itself on the fly if there is a bad sector on a hard disk or even a processor that is showing a high rate of self-correcting errors, the software maker said. Essentially, "self-healing" means Microsoft's defrag and chkdsk, or...

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change.

Telecom 2.0: Mind over matter

ntl:Telewest Business believes that the role of the telco is evolving. Gone are the days when it was enough to simply focus on circuits and minutes, customers now need a far higher degree of interaction and look for suppliers who will talk business solutions with them.
