Connect to your host via SSH

# Run this command to find additional peripherals and devices:
lspci -vvv

NICs I was able to identify.

  • Broadcom Corporation NetXtreme BCM5719 Gigabit Ethernet
  • Mellanox Technologies MT26448 [ConnectX EN 10GigE, PCIe 2.0 5GT/s]
# If you know what you are looking for...
lspci | grep Mellanox
# Verify the driver's version that is installed
esxcli software vib list | grep nmlx

Download the latest native ESXi drivers from here.

Copying the installation package to a datastore....

# Install new drivers...
esxcli software vib install -d /vmfs/volumes/<datastorename>/Mellanox-nmlx4_3.19.70.1-1OEM.670.0.0.8169922-offline_bundle-17262032.zip
# Perform reboot...
reboot
# Check if the nic is available....
esxcli network nic list

Apparently the NIC is no longer supported.
However, I have found several statements on this.

Hier wird auch ein Workaround präsentiert.

I have tried it and cannot confirm that it works.
I will now try another NIC.
I will write another BLOG entry about this.

  • Intel X520-DA1 10Gbps PCI-E SINGLE PORT Network Adapter

It appears to be compatible.

You can get it quite cheaply via Ebay....
I'll report back as soon as I have more information.
