Strictly speaking, there is no such thing as an official "3390-27" (or "3390-54") - they are just colloquial terms for large 3390-9s with approximately 3x and 6x capacity.
The size of each device can vary depending on the way your disks have been setup in the storage array. The only official "next" model number for disks after "3390-9" is the "3390-A" for EAV volumes. It is therefore slightly risky to assign "3390-27" and "3390-54" to a DASD volume by just using capacity metrics without applying local site knowledge.
