You are listing maximum power Patrick, but do you also have some data for idle power consumption between the Intel and AMD platforms that you tested?

Well, politics aside, I did solve that issue for myself though. Of course by choosing server hardware that uses less powerhaving photovoltaic and batteries installed :rolleyes:. Brings the effective price (if I consider the opportunity cost of not delivering a kWh to the net as actual costs) to...

Technically, yes, that would fit right with the European grid at 230V. The fact that we pay EUR 0.30 - EUR 0.80 / kWh means that at 1 kW 24/7, that would be a cool EUR 2.5k - EUR 6.5k in electricity per year :eek:

When the Unifi USW Flex 2.5G 8 PoE ("USW-Flex-2.5G-8-PoE") was announced, there was some noise on the net about these switches not supporting Port Profiles; according to the reports, you could select the untagged VLAN as well as any set of tagged VLANs you wanted, but not select a...

As I wanted to learn working with RDMA, I got myself a ConnectX-5 (MCX512A-ACAT; 2x25GBe); a second one will follow soon. Now, in addition to doing RDMA (and zero-touch RoCe in particular), these chips also have extended eSwitch functionality that is exposed using the Linux switchdev module. I...

I believe that is supposed to be called NOTWORK.

"Yes"

Angry European noises I wish we had outlets like that over here; I would have been in for a few of those.

These switches (along with their 4 x QSFP28 variants) do not support the 802.1 bits for RDMA, however, the ConnectX 4 and up do support something called zero-touch RoCe that should work even on not fully compliant switches. Has anyone had success using zero-touch RoCe on the Mellanox/NVidia...

This is good news indeed. Do be aware of the fact that your network-interface names in the kernel may change, so that you definitely need physical or IPMI access to your server when upgrading. See the discussion on this forum here.

FWIW, using the mechanism in https://pve.proxmox.com/pve-docs/pve-admin-guide.html#network_override_device_names worked well for me on another server.

I just upgraded two of my servers from Proxmox VE 8.1 to 8.2, and although there is just of good stuff, as outlined in the video , the upgrade to kernel 6.8 (although good in itself) changes the network-interface names in the kernel. In my case, on an Intel X710-DA2, the names changed: From...

That is one way to go. Personally, I have Caddy handle the SSL certificates and HTTPS work. Then, I use Authelia to only have authorized people (me) be able to even access the IPMI web pages.

"Lies, damn lies, and benchmarks" Whenever one defines success metrics, some will game the system for the sole purpose of achieving said metric. Another way of putting that is: "Any metrics that starts being used as a performance evaluation stops being a useful metric at precisely that time."...

I understand that this is Asus' 14th generation of product, but man, would SI3NA have been a great match, name wise :)
