General rule is 176 for 15K and 150 for 10K, IOPS per data SCSI disk. I believe SSD would be 48000 per data disk. ... View more

I believe you can do an ifconfig command with the new MTU size on the filer. You can verify it with ifconfig -a. I suggest making sure the network MTU size is greater than 9000 first. I would also make sure you can do this on both ends quickly, it can cause high processor utilization on some network equipment to support both MTU sizes. ... View more

Do you have DFM? I believe that 176 IOPS for 15K per data disk should be a reasonable number to use ( 28 data disks * 176 = 4928 IOPS for the aggr). You may want to look at disk IOPS instead of just IOPS, some request such as GETADDR does not go to disk, if you have PAM it will be cache so you can have much higher IOPS. ... View more

As long as the switch is set to higher than 1500 the switch shouldn't be part of the problem. I would do a traceroute from end to the other and see what there is between there, can all of connection points handle 10g, you could over loading the firewall if it has a 1G connection. I would also run a packet trace on both ends, make sure you are seeing packets of 1500. Is the connection encrypted? We found problems with the packet size of 1500 for VPN, we set it lower. We have two 10G connections from coast to cost, we are able advantage of the 10G.  Just my opinion,  it appears something is being overloaded when you went from 1G to 10G. ... View more

I don't think you can use LACP without a switch. You could setup two direct connections from the controller to controller, use two IP addresses. Chang the snapmirror.conf file to send half the volumes over one IP address and the other volumes would go over the 2nd IP address. ... View more

What is the MTU size on the 10G interface on the NetApp side? Do you have a firewall between the DC and how much bandwidth can it handle? We found a problem with jumbo frames on one end, it caused 100% CPU on the switch, changing from 9000 to 1500 packets. Most people use throttling when they have limited bandwidth between the DC, it doesn't seem to apply in your case. ... View more

I suggest a multimode vif with LACP (if your switch supports it). I would also control the bandwidth in the snapmirror.conf file, kbs=. You will have make sure the destination IP address is routed through this vif. ... View more

We have the same problem on a FAS6280, we can SSH into the SP port but cannot RSH or SSH into the e0M port. We moved the cables to another port on the same switch same problem, we moved to another switch and it worked. We are working with Brocade to find the problem, it appears to be a problem with the MAC address. The SP and e0M have different MAC addresses. ... View more
