Hello,
I am really new to 10gbe switches, so I appreciate your patience. Heres is the issue:
- Copying/reading files from my file server (unraid) to my PC (Mac or Windows) gets very mixed speeds ranging from (0.5G to 5G at best)
- When the 10Gbe NICs are connected (no switch) directly they get full-speed (10gbe, sometimes even 10.5+ which is nice.) the tests were performed using iperf3 (below are screenshots)
- I tried to use RouterOS and followed a few tutorials to setup everything from routing, dhcp…etc but the OS was just very just very unstable so now I’ve switched completely to SwOS, as it can be very overwhelming on RouterOS. (note: i am using both stable versions of the OS’s, not LTP and with the latest firmware)
- The speeds on the ‘Link’ page on SwOS show as 10g for the PC’s and 1G for my internet router (which is correct)
- Speeds seem to be variable but very similar when tested in Unraid/Ubuntu/Windows/Mojave or Catalina (I wanted to make sure it wasnt a driver issue)
The Setup:
- CRS305-1G-4S+IN
- 2x Ipolex 10G-SFP-T (https://www.amazon.com/ipolex-10GBase-T-Transceiver-SFP-10G-T-S-Supermicro/dp/B01M5LIUK5)
- CAT7 cables (5-10 feet) ← tried different cables I had, with similar results
- TN9510 10GBase-T/NBASE-T Ethernet PCIexpress (http://www.tehutinetworks.net/?t=LV&L1=3&L7=142) (on both OS’s the MTU is set to 9000 with jumbo enabled)
- Computers have really good cpus (9900k and 6700k both with 32gb ram, testing is done through /ram or high speed SSDs)
Connections:
Ethernet Port: Airport Extreme router (gets internet through wan port) functions as a bridge
SFP1: macOS/Windows
SFP2: Empty
SFP3: Unraid
SFP4: Empty
Q1: Are the Transceivers to blame? is my switch faulty? or are my NICS to blame? Did I forget to set something up in SwOS?
Q2: Is it possible that because I am getting my DHCP (I have static IPs on with the from the router, through the bridge the cause of the issue/s? (SwOS is set to DHCP with fallback)
Q3: also, is there a guide I can follow to try to get RouterOS to work on my setup? I’ve tried a couple but a lot of them seem to use models/setups that are very foreign to my setup.
Thank you!
