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? -- Andrew Piskorski <[email protected]> _______________________________________________ Beowulf mailing list, [email protected] sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
