Hi

I have just deployed the vSAN Free and my network interfaces on the proxmox hosts are 10GB, however the Vsan appliance only shows 1GB links.

I am deploying it on a two node Proxmox and using the below interface:

Settings for ens5f0np0:
Supported ports: [ FIBRE ]
Supported link modes: Not reported
Supported pause frame use: Symmetric Receive-only
Supports auto-negotiation: No
Supported FEC modes: Not reported
Advertised link modes: Not reported

Advertised auto-negotiation: No
Advertised FEC modes: Not reported
Speed: 10000Mb/s
Duplex: Full
Auto-negotiation: off
Port: Direct Attach Copper
PHYAD: 0
Transceiver: internal
Supports Wake-on: g
Wake-on: g
Current message level: 0x00000007 (7)
drv probe link

Any ideas?

This issue relates to how the network is configured inside the StarWind VSAN VM.
Please see if VIRTIO or VMXNET3 are used.

I have this issue also. I spotted the VMXNET3 driver being used in the guide and changed mine from VirtIO, but still shows as 1Gbps.

Any help much appreciated.

That's an issue with the driver on the Proxmox side.
Test the network performance with iperf3 to clear this concern.

Sorry for any inconvenience.
