We are getting a transfer rate of about 6-7GBs per hour from source to destination (Austin-NewOrleans) over our 40MB pipe. Network team reports that the pipe is only utilized at 10% with no other traffic. We called NetApp support and was asked to run some perfstats. In the end, they said the bottleneck was the source filer (FAS2040). Support said we were limited to our disks and to either add more spindles or upgrade to SAS. We currently have 1 AGGR (22 disks) (2 RGs = each with 11 disks), SATA 7200rpm drive. The only thing running on this source filer is 5 virtual guests. When trying to smapmirror the volume (460GBs) its taking a long time.. much longer than anticipated.
