Hi, this is very interesting!
Here's my Talos II Lite
- - 8< - - - - Cut

Seeing real numbers has finally gotten me motivated to clear out a disk, and test another distro.
Then I can also do some testing without full disk encryplion.
Will have to do some backup rotatoins first, thou

That is a pretty stark difference. What’s your storage configuration?

I have Btrfs on top of LUKS on top of Raw disk, no raid or stripe.

Hardware:
CPU --> PLX Technology PEX 9733 PCIe Gen 3 4x U.2 --> Western Digital Ultrastar DC SW630 NVMe SSD

I also have 2 other NVME-disks of different make and size, all are slow.

I always felt my disks are very slow, and now I have proof. In single thread, they are about just 10% of the others here. Even with LUKS, they should not be THIS slow, should they?

General CPU Discussion / Re: POWER9 water cooling kit

« on: October 07, 2020, 07:04:28 pm »

...
We're using an existing high-quality cooler (with different connectors where needed) with a custom-made high-pressure mount.
...

Hi, can I by one of these blocks with a custom mount  now?

Do you ship to Norway?

I am more or less going "all out" with this build. And custom water cooling loops is on the list of what I want to do :-)

...

The heatsinks sold by Raptor have IBM part numbers.  I wonder if they can get the water cooling blocks from IBM also.

That would be great, I want one too 

While it`s probably not too difficult to make a custom adapter for an off the shelves block. I fear it won't provide the proper pressure to ensure reliable contact on all the cpu pins over time.

Btw: My first post here, hello all! Great forum
