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
It should be passive cooling and have Intel holograms. There is a problem with the cooling of these units, replacing the paste under the heat sinks help.
Using jumbo frames or setting the MTU to 9000 helps. I've had better success with mellanox nic's
