I'm looking at several mid-range storage products and am interested in
anecdotal experience that people in this group may have had with these
products.  This storage will provide storage for email (unix mail app),
database (oracle), vmware, and file serving applications.  Our
implementation will have two arrays - a primary and a DR array and
we'll be using snapshotting and mirroring software to provide various
levels of data replication between the two arrays - some synchronous
and some asynchronous.  We have around 6TB of DAS storage that will
move to these arrays.  Projections are for our storage needs to top out
around 20TB spread between the two arrays - the DR would host some
tape-recoverable data.

Here are the products under consideration:

EMC CX3-20
HP EVA4000 w/DL 380G5 storage servers for file sharing & iscsi
Network Appliance FAS3020

I'd appreciate any thoughts on the good, bad, and ugly features of
these product lines.

Thanks.
