iSCSI & NFS Gimme

I am a HBA Fibre man but more times I'm being asked for iSCSI and NFS. Just one question -

Will these two storage connectivity methods support;

HA DRS VMotion

iSCSI definitely supports vmotion, drs and ha. I have it running in my test enviroment against a netapp 3020 filer.

I don't have any experience with nfs. But a quick search would probably give you the answer.

Hello,

Performance goes SAN > iSCSI > NFS usually. To use NFS you need to tune your NFS settings on the NFS Server and the ESX server. NFS is very slow if this tuning does not happen. There is a post about tunning NFS on one of the forums. I can not remember which forum however.

Saying that "Performance goes SAN > iSCSI > NFS" is like saying "Performance goes: Ferrari > BMW > Voltswagen". It's just a stupid statement, specially for a writer...

"To use NFS you need to tune your NFS..." What are you talking about? Are you saying that you have to tune all NFS systems, or are you saying that you don't have to tune SAN/ISCSI. Either way you would be wrong.

Hope your book isn't full of all this wonderful insight.
