Talk:RAID

I have revised the article and added more information. What still needs to be done:

• Only the most common RAID levels/level combinations are listed; there are some that are either not standard (because there is just one vendor with a closed-source solution), or not common (some people use 3 levels of RAID. If anyone is interested these should be added
• We probably need to link more words.
• I am bad at spelling things.

Ideally, this should become a GA sometime. --Eptalon (talk) 12:45, 14 August 2008 (UTC)

RAID PVGA

Hi Eptalon, you may (or may not!) have noticed I've made a few edits to RAID. I've got plenty to offer (it's an area I know a little about) so I'll be glad to help push this to VGA if you'd like a collaboration? The Rambling Man (talk) 14:48, 16 August 2008 (UTC)

Yes, that would be very welcome. I think there is ample room for work:

• The non-stadard RAID levels (see en:Non-standard RAID levels, but thats probably far too much)
• The nested levels: Currently we only list the most common ones; we could extend to listing more, but perhaps need to make it a higher-level section (see: en:Nested RAID levels)
• More references (also to scientific papers)
• More detailed desc of the benefits and drawbacks of the different levels.
• Better desc. of (historical) RAID 2. AFAIK there are no implementations at the moment, even though doing something like this would be pretty easy in software--Eptalon (talk) 15:02, 16 August 2008 (UTC)

Todo list

The following should be done:

• Proofread and edit to avoid saying things over and over again
• Link and explain words that are difficult to understand
• Remove/reformulate those phrases that sound like aren't English.

As it did not make VGA, we now have time to do this.--Eptalon (talk) 10:48, 13 September 2008 (UTC)

Does it have RAID file system?

Greetings!

The article says that RAID has a file system:

"A RAID array has one file system. This Creates a single point of failure".

Why does RAID to have a file system? That seems confusing, do not see the point. It was my understanding that RAID is independent of the file system, RAID merely translates the addresses of a virtual hard disk (RAID) to physical disk addresses. Not have to have a file system

(This was translated using the goole translator I am Hispanic) — Preceding unsigned comment added by Alexvillalb159 (talk • contribs)

What I tried to say there is: If you have a RAID volume, the whole volume has one filesystem; the RAID system itself (itependently of whether this is Hardware-RAID, Hardware-Assisted-RAID, or Software RAID) will translate addresses, and have some logic for building/re-building/recovering data. The Operating System will see one "block device". To be able to reasonably use that block device, you will need to create a file system on it. Yes the file-system layer is a layer on top of the RAID layer. Compare with DVD: the drive provides the logic to read (and perhaps write) DVDs, but to be usable the disks themselves have a file system (which is UDF, most of the time). The same holds for Compact Discs that contain data...--Eptalon (talk) 13:19, 4 June 2013 (UTC)
