The first thing that I noticed is that it is very difficult to find examples of the SAN/iQ UI. On the other hand Equallogic screenshots are all over the place. I stole this equallogic pic from here

So in the search to find out what the lefthand SAN will look like this is the first hit on youtube.
http://www.youtube.com/watch?v=z4BJtTZx8z4 I could not make this up if I tried, ok don't watch that it actually doesn't show the interface. That presentation puts me to sleep (not produced by lefthand to be fair) I wish both of these vendors had more information out for what their stuff looked like.
Ok, after some heavy googling I ran across some screen shots for the LeftHand SAN

I hope that can sort of give you a taste of what the different UI's look like. Maybe some Equallogic or Lefthand people will reply with screenshots of common interface tasks. (To be fair I should probably download the LeftHand virtual machine and get some screen shots from it, maybe in a future post)
