NSA4600 SFP back to back connection

BSNrick46037

I have 2 buildings that are next to each other sharing a parking lot. We've run fiber between the 2. Each building has a SonicWALL NSA 4600. I've plugged them into each other via the X14 ports using a SFP connector. I SHOULD be getting about 1gb of thru put or at least 700mb - 800mb (really). But I'm only getting 300mb between them. Any ideas? Please HELP!!

Hi@ BSNRICK46037,

Thank you for visiting SonicWall Community.

Could you please check if the SFP module used by you is as per the Supported List from SonicWall?

Let us know how exactly you are trying to measure the speed between the SFP links.

The part is 01-SSC-9790 and it is on the list. I'm testing with iperf, using an iperf server on one side and an iperf client on the other. Getting about 350mb where I should be actually getting somewhere around 700mb - 800mb.

Thanks for your confirmation @BSNRICK46037. Have you tried around with other SFP ports just for testing? If so, then we may need to perform real-time troubleshooting to diagnose the issue.
