I believe there is still a limit of 24 with DP.  Not positive though.

Don't forget there is double parity RAID on 6.5 and later.

Sure, just keep your raid group size at a reasonable level, to avoid double disk failures, and use multiple raid groups.  I had a semi-large volume running RAC for about a year which had 6 groups of 12, so 72 spindles in the volume.   (I certainly wouldn’t use a raid group of 72 though!)

Does anyone on the list have experience with RAID group size limits?

 

I seek to convert my qty 5 small volumes for Oracle into qty 2 volumes (one big, one little) for oracle and use lots of spindles. In fact, I’d like to just do a big, giant volume on my filer and put everything in qtrees shared/exported.

 

Anyone out there done this yet? Hit any RAID size limits?

 

Thx;
