I have recently purchased the following
Synology DS1817 NAS (not the + version, this version has 2 x built in 10GB NIC's & 2 x 1GB NIC's)
2 x Intel X540-T2 NIC's
1 x DLink DXS-1210-10TS 10GB switch

I installed the 2 x  X540-T2 in our Windows 2012r2 Hyper-V host. Each card has two ports. I have configured
all 4 ports as a team and connected each to the DLink DXS switch. All 4 connections are 10GB as expected - perfect!


Connecting the Synology DS1817 NAS I only get a 1GB connection. Local 2m CAT6 cable.

I raised a support case with Synology. Synology support got me to connect the 2 x 10GB NIC's together with a CAT6 patch lead
and connect the NAS to the DLink switch via one of the 1GB ports. Synology confirmed that the were getting 10GB communications
between the 2 x 10GB and concluded that the issue lay "somewhere else" on the network!

I have used tested 2m CAT6 cables from both 10GB NIC's to the Dlink DXS switch - both connect at 1GB
If I set the switch ports to 10GB I loose communication with the NAS.
All ports on the DXS are 10GB.

Anyone have any idea why, if the Synology DS1817 NAS is working correctly, I am not getting a 10GB connection to the DXS10 switch?
 
Thanks in advance
