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. [1] http://www.3par.com/library.html John
