What file sizes / access patterns are you planning on using? Smallfile and stat / metadata operations on Windows / Samba will be much slower than using glusterfs or NFS mounts.

I would expect 40-60 MB / sec writes and 80-100 MB / sec reads over gigabit with sequential workloads. Over 10G I would expect ~200-400 MB / sec for sequential reads and writes. Glusterfs and NFS mounts will perform better but it sounds like you need samba for your windows hosts. > > > > About the hardware I am not confident. One thing is the 10GBe card.

You will need a 10G switch if you want the clients to access the servers over 10G. If you don't need more than 120 MB / sec you can use gigabit, but if you need more then you will have to goto the 10G NICs. > > > > Could someone give me some advice? > > > > Thanks. > > > > Gao > > > > > > > > > Any help?
