I think I may have spotted a bug in this version. On the LUN requirements page, the number of SCR targets (and from that the total number of recommended LUNs) is using the number of scr servers field, not the number of scr targets. ie. I have 2 mailbox servers with one target.  I am doing single-node recovery. You get a pictures that look like these (apologies for the formatting - I can't paste pictures)

Regards
