Subject Re: C* on Fusion IO

I've heard of people running dense nodes (8+ TB) using fusion I/O, but with 10GBe connections.
I mean why buy a Ferrari and never leave first gear?

As far as saturating the network goes, I guess that all depends on your workload, and how
often you need to repair.

to scale out vs scale vertically.  But these boxes are priced aggressively and honestly I
think that cassandra would be able to saturate the gigabit ethernet port on these machines.
