Unraid and 10Gbe switch connecting to 1gb router

Hi all! Apologies if this is in the wrong section. It appears I'm a little out of my depth although it's all a good learning experience.

 

I've built a couple of medium size file servers (one for physical backup) for the small business I work at as we drastically needed to expand our storage and storage speed from regular consumer/enthusiast NAS enclosures. I thought I'd have a crack at it myself with Unraid!

 

Here's my problem. The main server uses 2x 10Gbe SFP+ cards (bonded) connected to our new Netgear 28port 10Gbe ethernet+sfp+ managed switch (XS728T). (I wanted to see if I could bond all 4 ports to eliminate any bottleneck on that side)

Specs are as follows (roughly):

-4 core CPU

-32GB ram (probably overkill)
-Samsung 970 evo 1tb Cache

-4x Samsung 860 Evo 1tb (for our 'faster' share)

-6x 8tb Seagate HDDs for storage & parity

 

It all appears to be working OK however when I'm connected to the switch on my workstation I'm only getting roughly 100MB/s transfer speed from my own NVME drive to the unraid  NVME cache - this is wrong and leads me to believe that I'm essentially transferring from my PC, to the 1gb router and then back to the unraid server at 1gbe.

 

There's probably something I'm missing but the method I'm using is slightly different to the guides I've seen online. Is there any way of getting whatever goes through the switch to just go straight to the server via 10gbe? This is where my knowledge ends as I'm mainly just a PC building enthusiast with a bit of budget.

 

*edit:

I managed to get a much better speed as one of the NICs was in a much slower PCIe slot which was limiting. I did a few tests copying from my NVME c:\ drive to the Unraid server and it reached speeds of about 600MB/s max - much better. The issue I'm having now is that whenever I copy a large file it starts off very slow (around 2-3MB/s then steadily reaching its way up to the 5-600MB/s mark over about 5 or 10 seconds. Is there any reason for this?

 

Thanks in advance

Harry
