My main issue with that kit is that the linux drivers are very basic, lack most management capabilities and fail often with obscure issues.
We certainly don't see a high frequency of obscure-cciss-issues. But since no place and/or work-load is the same I guess this difference isn't too unexpected.
And, as Peter pointed out already, they are not really exposing a proper scsi interface, but modeled around a really old ata stack.
One thing HP has attempted to do with all their smartarray cards is maintain RAID volume set compatability, so you can move a raid set from a failed server to another raid controller that has the same interface even if its a different controller..
This is far from always true, for example, raid6 sets are incompatible between quite similar controllers according to HP documentation.
