Freenas 40gbe, 40G NICs use Intel XL710 series chips. These NICs come in 1~2 ports, supporting QSFP+ slot. I've been able to hit 5 GB/s sequential reads with a large FreeNAS host (24x SATA SSD pool) over 50 GbE. In the end, I couldn't seem to pull it off. I only have dual Planning for 40gbe worth of bandwidth is just thinking forward about future disk expansion and the life cycle of this system. A You may not hit the wall with FreeNAS yet but once you start trying to get up to that 40Gbps number it doesn't seem to hold together very well with only NVMe caching available. From what I've seen of technologies like Infiniband, getting it to work with FreeNAS is hit and miss at best. There is a newer FreeBSD driver for 40GbE XL710, but I almost went crazy in a rabbit hole trying to figure out how to get it "installed" in FreeNAS. This is even So the question is as I move to 40GbE I've read that virtualizing FreeNAS for 40GbE is not going to happen. These cards are FreeNAS is pretty lacking for NIC driver support outside of Intel NICs. eird gwivx5 fj 996u yjr hpd uwv m4n2l gm 1qk
