Um, having had more than a few recent discussions with folks around 
disk capacity addressing limits and OpenVMS, no.

More than a few of the folks have found the OpenVMS volume addressing 
limit... surprising.

Cool.  I didn't see that HGST was offering small disks.

The web searches turned up for that string were capacities way past 2 
TB and variously out past 10 TB.

And I checked the p812 specs and docs again, and don't see any 
indication that the p812 supports storage partitioning.  Based on the 
specs and the doc, the logical drives are all seemingly as big or 
bigger than the constitutent drives. Lots of support for "bigger" and 
for adding and swapping spindles in arrays, but unless there's 
something buried in the advanced features or some other add-on, I don't 
see anything akin to the FC SAN virtualizing controllers and their 
pools of sectors.  Did I miss that?

More generally...  VAFS and NVMe and TRIM and AF 4K and other hunks of 
modern I/O support can't get here fast enough.
