I read that in the Venti paper[1]. I would not consider them UUIDs though, since the same data blocks will have the same sha-1 hash on both servers. If that doesn't cause a problem you're fine [1] http://plan9.bell-labs.com/sys/doc/venti/venti.pdf On 2/6/09, anoop.anoop@gmail.com wrote: > Hello All, > > I have a query regarding the scores in venti.
