    I like the cards. Rich for my taste though. Would be good for someone with a 10gb copper switch.

    This is blazing hot inferno if you use pfsense or freenas and copper.

    The T420 certainly does, though I highly recommend chelsio's driver rather than VMware's

    For ZFS nas/fileservers with out of the box drives included in freebsd based distros like nas4free or freenas.

    It's more that FreeBSD doesn't support the more common Mellanox Connect-X 2 cards which are a popular choice round here for cheap 10G

    My Connect-X2 card worked out of the box with my stock NAS4Free install?

    Support for Mellanox cards was added in FreeBSD 10.

    Are you kidding me? Now that I just purchased two ConnectX-2 cards, SFP+ modules and fiber patch cord, this comes around?

    SFP+ is still way better, 20 times lower latency and uses only a third of the power.

    Wow. I'm impressed with these cards. Need to pick up a couple of XS708Ts (or ES-16-XGs if they ever get fixed) and I'll be set.

    Win10 test box w/T420-BT (QOS disabled) -> 10 ft CAT6 patch cable -> Monoprice CAT6 tool-less keystone -> approx. 90 ft (guesstimate) run through my 2 storey house walls/attic of STRANDED "CAT6E" 600MHz cable -> Monoprice CAT6 tool-less keystone -> 10ft CAT6 patch cable -> Win7 test box w/T420-BT (driver signing disabled, QOS disabled)

    I followed zero "best practices" in my home environment. Monoprice recommends tool-less jacks to use solid CAT6 and punch-down with stranded.

    I was thinking about picking up a couple of the cheap mellanox cards, what is the benefit of these chelsio cards? I have a few server 2016 end points and a couple windows 10 machines, would there be any benefit to using the chelsio cards? I use hyper-v pretty heavily if that makes a difference.

    Thanks!

    Will probably be cheaper to go with the Mellanox cards as getting switches with SFP+ ports on them is considerably cheaper that ones with 10gb Base-t ports

    I agree, I misread the first post and assumed it was a chelsio sfp+ card, oops! I plan on purchasing the new ubiquiti switch that has both sfp+ ports as well as four copper ports but will use sfp+ whenever possible. So I suppose my question is how do the mellanox sfp+ cards compare to the chelsio sfp+ cards? There is a huge price difference, are the chelsio cards noticeably better? I would like something that handles sr-iov and rdma, at least for the server 2016 nodes.

    Thanks!
