Thanks Adam, glad to know I'm on the right lines in terms of what others
are using

We're about to deploy 3750X ... As per Dell, whose SANs we are 
deploying, this switch has been tested and is considered up to snuff by 
them.

Real world experience ... none yet.

and have always tried to err on the side of caution when choosing
switches and usually go for models with meaty buffers and was
considering for this deployment the 4948E. I was also considering the
3750X but not sure how the buffers stack up against the 4948 as the old
3750 models were poor in this regard.

available on this group can guide me
