We run diskless clusters these days and so we don't get a choice. :-) Seems to be fine - we use Slurm's cgroups support to constrain memory usage and don't overcommit memory. Java's been the only issue (defaulting to trying to allocate 1/4 the RAM of the node on startup) but Java 8 finally fixes that problem and so it'll now start in our default allocation of 2GB per core without any extra command line options.
