Setup takes about 72 hours and their support isn't half bad (not as good as Dacentec but a lot better than Commercial Media).
The IPv6 is a /64 but you need to open a ticket requesting it (mine was issued in less than 24 hours over the weekend).
Keep in mind that the RAID is hardware RAID also which makes the deal even better (but since it's a blade you're limited to 2 drives in RAID0 or RAID1).
