Interesting link for info  there.  I found [1] and at the bottom of the
page there is like tidbits of info in PDFs of the different models.  Any
idea where I could get more info than that, like data sheets and case
studies.

My main problem is bandwidth and workload.  Another problem is I am
being told there is such a thing as Triple Disk Mirroring.  Then I am
being told that there is not and all it is only Raid 1 with just
Replication to another Volume Set, sorta like a LVM Snapshot so to
speak.  Last thing is I am told GE is just rebranded Brocade.  Thanks
for the info & link.
