[Gluster-devel] really interesting interconnect

[Christopher Hawkins]

Wow, I didn't know it was that inexpensive. I've looked before and I don't
recall ever seeing deals like that... Guess I need to look harder.  ;-)
However, I would still offer the following points:  Gig-e is *already* built
into every server. A low latency ethernet translator might be an elegant
software solution to what has always been a "hardware" problem. If you can
solve the problem in software instead of relying on specialized hardware,
shouldn't you?

Well I guess I don't see why it is needed, I mean, infiniband does not cost
much at all on the used market. I just bought 16 dual 10 gig cards for an
avg cost of $83 including shipping from ebay and 25 port and 4 10 gig
switches cost me $1350 each. I don't think that is a lot to pay get 8
servers with 2 switches in two pops. The only downside is that gluster is
just not ready for production network, so I am now looking at lustre.
