There's nothing preventing you from r= unning everything on the same network=85(and more specifically, from di= fferent speed grades to different boxes, but keeping them all on the sa= me network). I mean using two cluster network and two pubic networks. 4 NICs in tota= l. Our cluster network will be 10GBe or Infiniband DDR/QDR, making a fully redundany cluster network (two nics on each server, two switches) will double our costs. -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
