40 GBit/s Infiniband
Tuesday, June 10. 2008
Mellanox made the silicon available for 40 GBit/s Infinimand: 40gig InfiniBand arrives. This is an interesting development as this gives Infiniband a nice performance advantage over Ethernet. In the race for the dominant interconnect for single fabric datacenter this really important.

Infiniband and Solaris? I can hardly think of anything more painful I tried this year!
Infiniband will never replace Ethernet. It is not designed for that, cant't be redundant and will burn CPU-power.

Try to use Mellanox Cards , their driver is stable and the documentation is up to date

Could you elaborate you findings with Infiniband and Solaris ? Iīve worked twice with it in the last months and didnīt find somethin especially painful ...
I think, used in conjunction with RDMA enabled protocols the load on CPU will me smaller than with a Ethernet. And of course cou can create redudant links into the fabric.
Of course it wonīt subsistute Ethernet for the campus network, but for the in-datacenter network this is a dofferent story.

Which cards did ypu use? SDR, DDR or even connect-X?
We tried several cards, but just the old crappy PCI-X cards from Voltaire worked with Solaris10U5/ Opensolaris.
What did you do with the IB-stuff? MPI? SRP?
Trying to avoid SPOFs with Infiniband like synchronizing 2 subnet managers on different networks it is painful! I don't think switches with integrates subnetmanager can be configured like this.

Okay, okay ... as several people have asked for it ... but you know my opinion.
