NAS I/O requirements
Larry needed more dbspace storage for IDS 10.0 on a Sun V880 and asked whether NAS works and what I/O specs to look for. No documented NAS I/O requirements were produced. Respondents advised preferring SAN or iSCSI over NAS: IDS works with all three, but SAN gives better performance/intelligence, raw devices on SAN LUNs work fine while many NAS boxes don't support raw. Art Kagel cited test figures (raw ~25-40% faster than cooked filesystem chunks, only ~3-10% with DIRECT_IO), and Bob suggested keeping LUNs small (e.g. 4-disk RAID 10) since each LUN has its own queue. Advice only, no formal resolution.

Has anyone had any experience with IDS and dbspaces on network attached storage? We have filled up our internal disk storage and are now looking into adding more storage using NAS. Is there any documentation on specific requirements for I/O speeds on using NAS (switcher and disks)? We have a Sun V880 running IDS 10.0.FC5. Larry
I prefer SAN disk over NAS. Thanks, Ernie Knox Sears Holding Co.

Larry, IDS works with NAS as it does with SAN based storage and iSCSI storage. I would go with iSCSI or SAN before NAS. The former for its simplicity and the latter for the added intelligence and performance available. Art Art S.

I don't think that the difference is that large anymore between RAW and COOKED; however, our current dbspaces are using RAW. I would just like to keep things the same across board if possible.

My experience is that every LUN on a SAN has it's own queue. Keep the LUNs as small as possible (4 disks in RAID 10) to make maximum use of IDS threading. Putting 8 disks in a large RAID 10 LUN and then having to put 3 dbspaces on that one LUN just defeats the purpose; especially when the read and write queues for that LUN get backed up. Of course, if the smallest disk that your SAN comes with is 300GB, well, you've got a 600GB (mirrored) LUN to work with. Or just stick with mirroring if you want for 300GB LUNs.
