We use dual E5-2660 V2 with 56 6T and performance has not been an issue. It will easily saturate the 40G interfaces and saturate the spindle io. And yes, you can run dual servers attached to 30 disk each. This gives you lots of density. Your failure domain will remain as individual servers. The only thing shared is the quad power supplies.

Can you please explain it in more details? I think he means that the 60 bays can be zoned, so you end up with physically 1 JBOD split into two 30 logical JBOD's each connected to a different server. What this does to your failures domains is another question. > > And again - is dual Xeon's power enough for 60-disk node and Erasure Code? I would imagine yes, but you would mostly likely need to go for the 12-18core versions with a high clock. These are serious $$$$. I don't know at what point this becomes more expensive than 12 disk nodes with "cheap" Xeon-D's or Xeon E3's. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
