The exclamation point was used to denote incredulity and frustration, not excitement. ;) 99% of 10 GbE deployment is switch stack interconnection, i.e. backbones. It's used very little in HPC environments--Infiniband dominates there. Very few servers today have 10 GbE connections. When they do they're used for dedicated iSCSI SAN traffic, not user traffic. Statistically zero desktops/workstations today are using 10 GbE connections. If they do it's for a specialized dedicated application such as satellite data stream processing, etc. In short, you likely won't be seeing 10 GbE outside the datacenter or internet POP/hotel any time soon. 10 GbE can transfer 1.25 GB/s in both directions. That's one quarter of a single layer DVD per second in each direction, 4 seconds to transfer the whole DVD. Very very few individual servers are capable of such sustained throughput. Thus, 10 GbE is used almost exclusively as an aggregation pipe, or backbone. -- Stan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
