As I replied to another post, I think it's unfair to say that HP storage is 
broken. We have roughly:
 30 p400 (mostly 2x raid1)
 50 p800 (mostly 12x1T raid6)
 <10 other cciss

and the only problems we really suffer is:
 * performance is not great
 * /dev/cciss is not a scsi dev (which is a minor annoyance in linux at times)
 * 1T seagate drives fail at many times the rate of hitachi
