A great thought on the thumbnails, but the behavior exhibits even when using command-line tools.

Indexing is off for the entire drive, I can’t even begin to imagine what kind of mess that would make if it was on.

For anyone - including, apparently, this article’s author’s - who is confused about the form factor, this is the next generation to follow the Grace Blackwell “GB300-NVL72”, their full rack interconnected system.

It’s the same technology as the matching 8-GPU “HGX” board that is built into larger individual servers - which in this generation’s case is just called “B300” as it has the “Blackwell” GPU but not the “Grace” CPU - but not sold in smaller units than an entire rack.

Here are some pictures and a video of that NVL72 version (you can buy these from Dell and others, as well as direct from Nvidia):

The full rack has 18 compute trays, each with 2 of the pictured board inside (for a total of 36 CPUs and 72 GPUs), and 9 NVLink switch trays that connect every GPU together. PSUs and networking make up the rest.

“Fun” fact: if you think it’s slow normally (and to be fair, it is), NTFS seems to have a pathological performance regression when a directory contains more than 10,000 children, any operations on files in that directory slow down by around 95%.

I discovered this on our CCTV system at work (that runs on Windows Server 2022), which creates an inordinate number of small files (each containing at most a few seconds of video). It was causing some of its periodic maintenance tasks to fail, as they’d take longer to run than than the configured interval between them.

Windows also really doesn’t like dealing with half-petabyte filesystems, just like… at all.
