My BlueField-2, finally I managed to get it flashed. Between the rshim driver's console being broken on my CachyOS install, and the card running custom SecureBoot. So many close calls. But finally, after the last hail mary of trying the default UEFI password […] [Original post on furry.engineer]

I fought very hard for this one log line. But I finally have end-to-end RDMA/SMBDirect between my NixOS NAS and my CachyOS workstation. On an SR-IOV VIF of the card, without running VMs.

Except from dmesg showing a couple log lines, the important one being "VFS: RDMA transport established"

There. Now I can keep track of how much noise my gear makes in my homelab :3

PSA: Check the thermal paste on your LSI HBAs. Mine just died so I took the heatsink off and the thermal paste was more a thermal solid. Repasted the replacements I got immediately and the paste situation was similarily terrifying. Took a lot of scraping to get it off even.

Let me show you: The Cisco CPU PnP tool, which is, of course, required to swap CPUs on your Xeon E-2600 based server. I especially highlight a specific excerpt from the beginning of the manual.

A photo showing the Cisco CPU PnP tool in front of its instruction manual, which covers a full 8 pages describing how to remove and replace the heatsink and CPU on a standard server socket.
The tool is also shown together with 3 different adapters for specific revisions of the LGA 2011 socket. The tool looks like a big stamp with a round, bulbous button on top and alignment arrows on the corner.

A second photo of the same tool, this time showing the device from its side, revealing it to be a fairly complex construction with springs and mechanical latches triggered by what looks like a big bulbous button on top.

Close-up of the manual for the device. The first paragraph reads:

You will use these procedures to move a CPU from one server to another, to replace a faulty CPU or to upgrade from one CPU to another.

After this, there is a second paragraph within a "caution" labelled section:

The CPU pick and place tool shown in Figure 2 and Figure 4 is required to prevent damage to the connection pins between the motherboard and the CPU. Do not attempt this procedure without the required tool, which is included with each CPU option kit.

Quick question: Is there a floppy drive "emulator" (like the Gotek or such) that works for *slimline* floppy drives. Picture for reference of exactly what type of drive I mean.

This might not be a good design, or an efficient design. But it is my design. And it gets the job done (Chorus Fruit). And I like the way it looks, too, which is a requirement.

Once I actually get usable fiber adapter for this thing (already on order), this will be a whole lot of silly fun. Definitely not useful fun :3

Somehow, in a certain way, there's nothing as relaxing as listening to records. The impulse to constantly skip tracks suppressed by the inability to do so. And in a way I feel this is actually helpful to me. Picture related, it's my setup :3
