Why aren't you thinking about NFS?

I tend to put technologies in three buckets - small, medium, large. It's usually because one is bigger/faster/more expensive than the other and its a quick simple way to put things in context.
If I carve up Storage Area Networks (SANs) in those buckets.

Large - Fibre Channel (i.e. EMC Clariion)
Medium - iSCSI (i.e. Equallogic's PS100/PS300)
Small - NFS (i.e. NetApp)

Last week announcement by Autotrader, got me thinking why is NFS in the small bucket - it's 1 GB just like iSCSI so I decided to redo my mental ranking

Large - Fibre Channel
Medium - iSCSI/NFS
Small - DAS (traditional direct attached storage)

10 GB iSCSI and NFS's I/O vs. 8 GB Fibre Channel - that's could flip it again.

Large - iSCSI/NFS (1/10 GB)
Medium - Fibre Channel (1/2/4/8 GB)
Small - DAS (traditional direct attached storage)

I like this blog's view as well.

"in a few years, the world will realize that using iSCSI or FC SAN with vm-zen-ness is stoopid. "

No one wants to be stoopid.
