Cool result! I've done similar things in the past with previous company's units[1] using Mellanox cards. We worked quite a bit with Chelsio as well, and have shown nice results there. I am surprised on the spinning disk front though, as I was showing off about 5.5-6GB/s for previous company's 60 drive bay units 3 years ago[2]. This was a single PCIe gen3 x8 NIC, we were bounded by the IB network (56Gb) performance, and had about 2GB/s extra headroom on the pure spinning disk systems.

- kev009 9y agoLine-rating 100g DC networking is close to plug and play today with Chelsio's zero copy stuff inside a LAN/MAN. Single digit CPU util. The needs of long haul TCP are a bit harder. Check out the TCP RACK RFC and packet pacing to get an idea of how many timers you have firing off. Also HTTP and TLS vs block protos. Netflix numbers are very impressive with all that in light.
- shaklee3 9y agoCurious, do you know of anyone using chelsio in production? Their cards look awesome and have tons of features to put them on par with mellanox, but I haven't really heard of anyone using them.
- justincormack 9y agoMainly used in HFT, but I believe Cloudflare use them.
- hpcjoe 9y agoA financial *aaS provider whose infrastructure we built used them. The cards are very good, I am looking at them for current (platform) projects. Generally they are one of two choices for very high performance networking on multiple OSes. The other being Mellanox of course.
