Does anyone have performance stats, or opinions about performance, across the different disk configs available (250GB ATA, 300GB FC, 144GB FC, 72GB FC) on the FAS3050?
We are going to be bringing in a few FAS3050c's and I'm contemplating going with either 300GB FC or 250GB ATA. The plan is to put semi-archive data and active Windows user home directories on there. Currently we are using a FAS940c for the 10,000 home directories and it doesn't break a sweat outside of backups. I'm expecting about 12,000 active connections split between the 2 cluster nodes and about 9k-10k CIFS OPS, along with 1k-2k NFS OPS. I know the FAS3050 can handle it per specfs (and common sense), but of course I'm not going to 15K 72GB disks as they did in the benchmark. Would my users see a slight delay if I go with ATA? With ATA will the minra=off be a good idea even though my cache stats warrant it to be on per NetApp's recommendation? Will there even be that much of a cost savings with ATA considering RAID sets must be must smaller than with FC disks? (We use close to the max RAID size since these areas can deal with the 24 hour outage to recover the data). Thanks all, Jeff
