I assume nothing is going on at that point in time (mass snapshot deletion etc) and the time it slows doesn't follow any pattern?

Subject: Brief outages on the filer?

I am seeing brief outages where my VMs (NFS as the back end protocol) and SQL LUNs (FC) both complain of poor disk response time at the same time. I don’t think it can be the infrastructure since one is IP and the other FC. The LUNs are on a different set of spindles/different aggr then the NFS volumes as well, so I don’t think it’s a disk bottleneck. I’m on a 3070 and rarely do we hit 3500 IOPS (and 90+% of that out of cache) or go above 40% for the busiest CPU (normally we’re in the 15-25% range) so I am not sure what’s going on here, any suggestions on how to troubleshoot it?

We’re running 7.2.4, I want to wait for 7.3.1 to upgrade since we are using NFS for VMware and there are several fixes that will be beneficial to us.
