When did RAID 5 debut?

Pages: << < (2/3) > >>

shmokes:

Pentium III or Pentium II. 

1999

Too much bulk and weight for the processing power if you ask me.

Oh, I'm not saying that compaq servers aren't built like a tanks and won't last forever, but the compaq brand SCSI drives/caddies that you'll have to use on an older compaq arrays, etc will be fairly expensive for the amount of storage you'll get out of it.

If it's a 1600, then it's pretty old and won't support large'ish drives.  I have an old compaq server (at work) that was "state of the art" back in '99 that has multiple raid5 arrays (one with 16 drives) but the drives are 18gigs each.....

We used to be an all compaq server shop (save for a couple of SGI racks we had for scientific stuff) until we got bought out and switched to IBM, so I'm very familiar with compaq servers

History

Norman Ken Ouchi at IBM was awarded U.S. Patent 4,092,732 titled "System for recovering data stored in failed memory unit" in 1978 and the claims for this patent describe what would later be termed RAID 5 with full stripe writes. This 1978 patent also mentions that disk mirroring or duplexing (what would later be termed RAID 1) and protection with dedicated parity (that would later be termed RAID 4) were prior art at that time.

RAID technology was first defined by a group of computer scientists at the University of California, Berkeley in 1987. The scientists studied the possibility of using two or more disks to appear as a single device to the host system. [1]

In 1988, RAID levels 1 through 5 were formally defined by David A. Patterson, Garth A. Gibson and Randy H. Katz in the paper, "A Case for Redundant Arrays of Inexpensive Disks (RAID)". This was published in the SIGMOD Conference 1988: pp 109–116. The term "RAID" was first introduced in this paper; it spawned the entire disk array industry.


Wow...that took me like 30 seconds to find.

Well yeah, but to be fair you probably have an attention span. ;)

If it had hit 31 seconds, I never would have made that po.....ooooooooo shiny!
