Some specific servers like SANs go direct 10GE, particularly if you&apos;re going to have 1-2 SAN interfaces and a bunch of clients (so you can use the 10GE uplink ports for it).&lt;p&gt;Enough things are CPU/memory/etc. bound that the &quot;cheap&quot; building block of a 1-2CPU server with 4GE, RAM, and some local disk is still more appropriate than buying a Xeon E7 with 10GE HBAs, in most cases.  There might be an exception if you have per-host vs. per-core licensing for expensive stuff, or other artificial complaints, or a specific component (database?) which doesn&apos;t horizontally scale.&lt;p&gt;I predict $5k 40-port 10GE switches and commodity server on-board 10GE NICs in a couple years, though.  Although at that point, you need something crazy to uplink the switches.  40GE is emerging, or you could use a non-ethernet option.  SANs are the big application for 10GE now since you can comfortably fit all the clients and servers on a standard 10GE switch and don&apos;t need to uplink most of the traffic.  Part of the issue with the higher speed ethernets is lack of a copper cabling option, particularly one which works with existing cable plants.  (less of a concern within racks).</text><parent_chain><item><author>jbooth</author><text>Even without crazy fabric setups, how have we been stagnating at 1GbE for like 10+ years now?
