In reply to James.

James – HPE’s HGX tray slides out to service on rails. Dell’s is perhaps the worst in the industry since it requires pulling the chassis out of the rack and disassembly to get to the HGX tray.

Speaking of ODMs and subcontracting; I was a little surprised by how prominently “CoolIT” was presented in the design. Do they have sufficient presence/reputation for not leaking/a de-facto standard for fittings at the rack level that customers specifically want them rather than whatever ODM HP feels like farming out to?

It’s obviously not uncommon for various supplier brands to not be entirely scrubbed(fan labels, PSUs, sometimes some embossing on a CPU socket or heatsink); but they tend not to feature quite as prominently as the CoolIT ones do here.

Slightly awkward sentence structure here:

“Unlike the Dell it requires one to pull the entire chassis out of the rack to replace GPUs, the HPE has a tray with liquid cooling blocks on each GPU.”

So is the Dell better, or the HPE better? Because it sounds like the HPE requires you to pull the entire chassis out, but then you go on to explain that the HPE has a tray for the GPUs.
