raid size limit was 28 disks in previous version of ontap i'm not sure if it had or not change to 14 now with 36G disk, you can set a 14 disk raid size if you really want 28, you can consider using a double parity you should not experience any performance penality when using double parity : << Depending on the type of write, performance on RAID DP can be about 2% to 3% slower than that of RAID4.

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?
