Upgrade to 25 Gbps Ethernet

[geerlingguy]

I purchased a PCIe Gen 4 SFP28 NIC with Intel E810-XXVAM2 on Amazon, and would like to install it in the server to get dual 25 Gbps Ethernet on the NAS.

Some of my other gear is starting to come online at 25G, and it would be nice to have a storage target capable of saturating the network!

Intel has a driver download page here: Intel® Network Adapter Driver for E810 Series Devices under Linux*

Interestingly, the SOL console in the BMC is spitting errors like:

And then the system won't continue booting.

[geerlingguy]

I think I'm running Ubuntu 20.04 on the HL15... it might be worth attempting upgrading to 24.04 :O

Otherwise maybe I can manually install later Intel drivers?

[geerlingguy]

On Ampere's recommendation, I'm going to try a ConnectX-5 Mellanox card, the MCX512A-ACAT, instead.

Now I have a spare E810, ready to go into one of my Windows PCs :)

[geerlingguy]

I have the X-5 installed, and it seems to enumerate correctly:

It's not getting an IP address automatically, though. Not sure why.

[geerlingguy]

Not detecting a link...

I'm using a 10Gtek 25G SFP28 DAC - 3m, 30AWG, Passive... I wonder if this DAC isn't able to work with the card? Weird.

When I plug in the DAC, I see the changes:

Supported FEC modes: None BaseR RS  # was 'Not Reported'
Advertised FEC modes: None  # was 'Not Reported'
Port: Direct Attach Copper  # was 'Other'

But it still says Link detected: no.

On the switch (Mikrotik 25G), I'm seeing the link as negotiated at 25G:

[geerlingguy]

Strangely, at some point this morning, it looks like the Intel interfaces were giving a bunch of errors:

[49658.032378] pcieport 0003:00:03.0: AER: Corrected error message received from 0003:03:00.0

[49658.051003] ixgbe 0003:03:00.0: AER:    [12] Timeout 

And the Mellanox driver is detecting cable hotplugs:

[58773.924177] mlx5_core 0004:01:00.0: Port module event: module 0, Cable unplugged
[58783.083281] mlx5_core 0004:01:00.1: Port module event: module 1, Cable plugged

Since this is 20.04, and I don't have NetworkManager present (so no nmcli), I ran:

sudo ip link set enP4p1s0f1 down
sudo ip link set enP4p1s0f1 up

And dmesg shows:

[59410.830394] mlx5_core 0004:01:00.1 enP4p1s0f1: Link up
[59410.833804] IPv6: ADDRCONF(NETDEV_CHANGE): enP4p1s0f1: link becomes ready

While ip a shows:

    link/ether 6c:b3:11:29:4d:43 brd ff:ff:ff:ff:ff:ff

So now it's getting IPv6, but not IPv4...

[geerlingguy]

Huh. Forcing a release/renew grabbed an IP for the interface:

sudo dhclient -r enP4p1s0f1
sudo dhclient enP4p1s0f1

jgeerling@nas01:~$ ip a
...
4: enP4p1s0f1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000

    inet6 fe80::6eb3:11ff:fe29:4d43/64 scope link 
       valid_lft forever preferred_lft forever

Now the question is, will the configuration persist across a reboot?

[geerlingguy]

Nope. But following this Stack Exchange answer, I did the following to make the new card's Ethernet interfaces persist with IPv4 DHCP across reboots:

$ sudo nano /etc/netplan/00-installer-config.yaml

# Add in the interfaces among the others and save:
    enP4p1s0f0:
      dhcp4: true
    enP4p1s0f1:
      dhcp4: true

$ sudo netplan apply
$ sudo dhclient -r enP4p1s0f1
$ sudo dhclient enP4p1s0f1

And now even after a reboot, I'm getting full 25 Gbps bandwidth, yay!

I guess the 00-installer-config.yaml is created at system install time, and since this card wasn't present, it doesn't show up there. Ah well. I could create 99-mellanox.yaml and tack it on that way, but as this hardware change is likely permanent(ish), I'm happy just throwing the config in the installer.
