Running 8.1 Cluster in FAS 3040 iSCSI and NFS

Hi guys, an year ago we upgrade our 3040 to 3240, so now we going to use this old 3040 for lab and other IT operations.

i upgrade it to 8.1.4 Cluster, the lastest Ontap that support 3040, and i design to use iSCSI because i like it's MPIO, whihc NFS doesn't do.

now i am running some branchmark in it mutiple VMs under either single NFS or single iSCSI Lun, i found iSCSI are slower then NFS a lot under load. this is a bit supprise me.

i would expect an even or iSCSI faster.

i know that 3040 running in cluster 8.1.4 does not support SAN at all.

but i wounder anyone out there tested 8.1.4 iSCSI and NFS performance in their lab?

which could give me a light on which i should use? and why?

thanks

Regards

Jeff Fung
