We give users access to local disk space on nodes (spinning disk for older
nodes, SSD for newer nodes), which (for the most part) GE will address with
the $TMPDIR job environment variable. We have a "ssd" boolean complex that
users can place in their job to request SSD nodes if they know they will
benefit from them.

We also have labs that use non-backed up portions of their network storage
(Isilon for the older storage, DDN/GPFS for the newer) for scratch space
for processing of pipeline data, where different stages of the pipeline run
on different nodes.
