I am looking at Lustre 2.4 currently and have it working in a test
environment (actually with minimal shouting and grinding of teeth).

Taking a holistic approach: What does ZFS mean for HPC? I am excited
about on the fly data compression and snapshotting however for most
scientific datas I suppose dedupe is a bit pointless.

Are raid controllers a thing of the past?

how often to bits flip anyway? What impact does this have? Does
checksumming save our data?
