Thread-topic: [Xen-users] iscsi/nfs/aoe SAN storage for Xen
I wholeheartedly agree - there's nothing technically wrong with them.  They are 
very solid, high performance units with great interfaces, and fantastic 

But I had a very poor marketing experience with them (and I know others who 
have, as well), and so I can't recommend them.  The same goes with the Coraid 
units - they may well be excellent units, but I (and, I am sure, many others) 
find their marketing to be deceptive and insulting - and I completely refuse to 
support any company attempting to tell me that an AOE switchport costs a penny 
more than an iSCSI switchport, when I have both technologies in production, on 
the same switching equipment.

Maybe Equilogic's marketing was changed in the Dell acquisition - in which 
case, I now know what company their marketing people have moved to.  :)

Thank You,

There's a lot of bad marketing out there for sure--Coraid doesn't have a lock 
on that by any means.  There's nothing technically wrong with Equallogic units; 
we have one of those too.

My advice is:  Try each out for yourselves.  We did exactly that.  What 
eventually sold me on Coraid is that they "Just Work" and I could get perhaps 
10 of those for the price of a single competitor's unit.  Plus they are easy to 
stack for growth and reliability.

I'd be happy to share our experiences further (off list) to anyone interested.

Really though, I don't understand why AoE isn't more popular.  The main 
drawbacks I can tell is that it isn't a standard and has somewhat limited 
driver support.  But AoE works perfectly well with Linux and Xen, which are 
mainly what we use today.
