RAID limitations – an interesting read

Posted on 02 October 2009

I was doing some reading the other day and came across several blogs about the limitations of RAID and in particular RAID 5.  Since I use RAID 5 on a number of systems at work, this of course gave me some pause.  On my larger SANs I’m using RAID 50 which should mitigate most of the potential issues.  I’m not saying these blogs are gospel, but they are worth thinking about next time you configure new storage and definitely worth reading.

Limitation of RAID 5 in large storage systems (>12 TB) (note the blog entries are dated 2007 so a bit old)

Interesting bit on Suns RAIDZ which overcomes RAID 5 limitations.  Good if your running sun gear.
