WAL is 1G (you can allocate 2 to be sure), DB should
always be 30G. And
this doesn't depend on the size of the data partition :-)
DB should be either 3, 30 or 300 depending on how much you can spare on the
fast devices. 30 is probably good in this case though.

Some say using 2x (ie, 60 in this case) helps when temp space is needed for
compaction, and since the 960G will only see WAL/DB for 6 drives for now,
it would only consume
180G, so you might aswell go for 60G WAL+DB, and still be able to fix 2x as
many data drives in using the same sized WAL/DBs too.
