Yes, there is a significant performance difference between Infiniband and GigE. Infiniband's latency is 1us and bandwidth is 20Gbps (40 Gbps capable already) . GigE's latency is between 30 to 100us at 1Gbps. Infiniband has become affordable. For example, Flextronics 8-port Infiniband switch costs $2,824. Flextronics 24-port Infiniband DDR switch costs $7,609. Cisco, Voltaire IB switches are slightly more expensive, but still way too cheaper than 10GigE. Here is a good summary: http://www.mellanox.com/applications/IB_performance.php When you use Infiniband, GlusterFS uses RDMA (remote direct memory access) for communication. Meaning, TCP/IP and local/remote CPUs are bypassed. 10GigE is still not mature and very expensive. Hope this helps. -- Anand Babu Periasamy GPG Key ID: 0x62E15A31 Blog [http://ab.freeshell.org] The GNU Operating System [http://www.gnu.org] Z RESEARCH Inc [http://www.zresearch.com] Jean Spirat wrote: > Hi, > > I have seen the benchmarks on the gluster website and i wondered if > there is a big difference between infiniband and tcp/ip performances. > Anyone can share some stats on this i do not know the infiniband > technology at all. > > regards, > Jean. > > > > > _______________________________________________ > Gluster-users mailing list > Gluster-users at gluster.org > http://zresearch.com/cgi-bin/mailman/listinfo/gluster-users >
