This is exactly my biggest concern, I don't know IB, IB hardware is hard to find from my distributor and currently is not useble for anything else except for storage. A 10GB ethernet (even better a 10GBaseT) would be used for everything, even for our local offices in case we need to change some parts. I can dismiss one 10GB switch from datacenter, replace it with a newer one and use the replaced one in our offices. The same would not be possible with IB as i'll have to redesign the whole office network or similiar. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
