That says that if you take 20 fairly high-performance each doing do
1.3 GB/s local disk IO, FhGFS scales linearly across them, giving you
about 25 GB/s total to your parallel application. Interesting.
What about the more bargain basement case? Say you have a cluster of
10 to 100 compute nodes each with only one or two SATA disks. Can you
usefully run FhGFS across those thin nodes? How well (or poorly) does
that work compared to using a smaller number of fat storage servers?
