I know that CCISS is the name give to a RAID device that comes from COMPAQ/HP, but why this name? Does it have any meaning?
Compaq Command Interface for SCSI-3 Support
It probably had a meaning inside of HP/Compaq years ago (I imagine deep within the Storage Systems Engineering group), but as far as I can tell, it's never been published.
I've wondered that myself.
"Card-Controlled Integrated System Storage"?
