Hello -- frequent listener, first time caller. If this should be redirected to another freebsd-* mailing list, please let me know. I've been experimenting with multiple dual port Mellanox adapters in a system, to see if the entire solution would be suitable for a router replacement project I'm doing. In general, I've been impressed with the Mellanox drivers and their responsiveness, however, I have encountered a few issues where the cards seem to 'fall asleep' or, when I'm playing with the sysctl settings for the mlxen drivers, I panic the kernel. Of course, before I finish spec'ing out a solution to be purchased, I should solicit real-world feedback on the available 40GbE adapters and drivers. >From what I've gleaned, Mellanox, Emulex, and Chelsio all support the development of FreeBSD drivers for their 40GbE cards. Are there any other vendors I should be considering? If anyone else has tried 40GbE cards, I am most interested in your experiences -- especially in stability, performance and performance tuning. Thanks in advance! -- John Jasen (jjasen@gmail.com)
