I have a netapp f760 clustered running 6.01R3 with the following slot assignments:
slot 9 nvram slot 8 cluster interconnect slot 7 redundant fiber loop slot 6 intel fiber gig card slot 5 intel 100mb card slot 4 primary fiber loop
One 7 x 18gb fiber shelf, one volume.
I can't seem to get more than 10MB througput a little worse than on the 100mb card. The cpu numbers drop but so far the gig card isn't a big win.
I've tested from a sun 420 with a syskonnect fiber gig card in the fast pci slot. I've played with about every combo of negotiation, etc. Tested with a cisco 6408 gig card in a cisco 6509 switch and also tested card to card with just a fiber cable.
Here is sysstat:

1) is it better to have the primary loop in slot 8 and move the cluster interconnect? 2) how is everybody elses netapps laid out? 3) do i need more disk to get better performance?
