Re: raid level
These are RAID1 and RAID5 consisting of several numbers of disks (2d+2d = mirrors, 7+1 = raid 5, consists of 7 data and 1 parity disk and so on ...) - these terms are used related to XP and P9000 disk arrays.
Hope this helps!
Regards
Torsten.

Re: raid level
As the XP / P9500 are based on Hitachi gear you might find more details if you search for HDS/Hitachi.
For example.
This blog (with broken .bmp pictures..) http://gestaltit.com/all/tech/storage/devang/hitachis-hds-raid-6/
has some more information.
