    Dedicated 2.5GBASE-T SFP+ transceivers that run cooler than 10GBASE-T transceivers?

    My main switch (MikroTik CRS309-1G-8S+IN) is running very hot with 3 10GBASE-T SFP+ transceivers (even spaced in non-agacent ports). I did the popular fan mod but it was loud and only kept the closest port cool. I have a 10GBASE-T NAS, a 2.5GBASE-T WiFi Router (Multiple VLANS--untagged so it...

    Addition of Layer 3 benchmarks to switch reviews

    In shopping for switches for edge locations and I've notice that none of the vendors, except for Mikrotik publish L3 routing benchmarks, and almost all the review sites only test L2 switch performance. Especially for edge locations, Inter-VLAN routing and static routes are the most important...

    10GbE NIC in PCIe 2.0 x1 (x16 slot), Will this cause problem?

    Hi everyone, I want to upgrade my custom build TrueNAS to 10GbE. However, I find that the motherboard only remain a PCIe 2.0 x1 (in x16 slot). I accept the low bandwidth (5GT/s) but I would like to know if the card will fail to work in that slot. Any recommendations are welcome :) Thank you.
