With this card you really need multiple cpus and multiple threads sending data through the card in order to fill the 10Gb pipe. Single connections will not fill the pipe. The server is a Sun X4600 with 8 x dual-core CPU's, setup with 64 NFS-threads. The other end of the fiber goes into a switch with gigabit ports connected to 48 dual-core cpus. The test was done doing a dd on a 4.5GB file from the server to /dev/null on the clients. A single file transfer will not fill the pipe using this card, no matter how many cpus you have :-) The card is designed such that multiple parallel data streams over different connections result in the greatest throughput. Should this setup not be able to fill the pipe?
Nope, not with this card. | ||||||||||
