And this give you the possibility to have a fully feature OS.
What kind of hardware would you use to build up a switch?

Hard to beat the Quanta T3048-LY2, 48 10 gig, 4 40 gig.

Hi Christian,
When you say 10 gig infiniband, do you mean QDRx4 Infiniband (usually
flogged as 40Gb/s even though it is 32Gb/s, but who's counting), which
tends to be the same basic hardware as the 10Gb/s Ethernet offerings from
Mellanox?
A brand new 18 port switch of that caliber will only
I've done this two ways in the past. Either I'll give each machine an
Infiniband network link and a 1000baseT link and use the Infiniband one as
the private network for Ceph, or I'll throw an Infiniband card into a PC
and run something like Vyatta/VyOS on it and make it a router, so IP
traffic

IPoIB is more common, but I'd assume that IB-Ethernet bridges

But that won't give you redundancy if a switch fails, see below.

First, thank you for your reply
TRILL ( http://en.wikipedia.org/wiki/TRILL_(computing) ) based switches
(we have some Brocade VDX ones) have the advantage that they can do LACP
over 2 switches.
Meaning you can get full speed if both switches are running and still get
redundancy (at half speed)
Thank you for your reply,
We use a stacked pair of Dell Powerconnect 6248's with the 2*12 Gb/s
interconnect and single 10 GbE links, with 1 GbE failovers using Linux bonding
active/backup mode, to the four OSD nodes.
I'm sorry, but I just have to ask, what kind of 10GbE NIC do you use? If
Thank you for your reply,
I really would think about something faster then gig ethernet. Merchant
silicon is changing the world, take a look at guys like Quanta, I just
bought two T3048-LY2 switches with Cumulus software for under 6k each.
That gives you 48 10 gig ports and 4 40 gig ports to
