Just a note: this three-phase PDU is metered but not "managed" like the single-phase one which the post was started about. I don't know which features are omitted on "metered" PDUs - possibly it's not switched? And possibly it's not metered-by-outlet? Eaton's website is unfortunately difficult...

As long as they actually work, I wouldn't need a warranty or anything. Just a guarantee that they aren't DOA.

I'd buy them from you, but not for the insanely high price they market for :-) (they're useful to us, but marginally so - more power efficient than a K40/M40, and only waste a single slot, but really slow at DP, which we use, so it's a trade-off).

What size 15k hard drives?

Why does it need to generate 1.8TBW to write 100GB?

Yeah this is sadly going to make buying used enterprise SSDs a very risky proposition :/ Crypto is literally destroying all the good things. Put another way, crypto seems to be Capitalism's Achilles heel.

Agreed and to my viewpoint, it's really all disadvantages except using less copper - except in exceptional circumstances, I'd prefer 240V for higher PSU efficiency. But those exceptions do exist - e.g. in my building we have 480V input like you mentioned, and if I wanted to add more power to my...

I think you mean 120V three phase (not 208V three phase)? 208V is what you get when you combine the hot wires from any two of the three 120V phases. I guess we should speak technically because that's simpler - something like 208Y/120V.

I suspect all of these with a QSFP28 port are the exact same physical hardware card, so cross-flashing should work if it is permitted (like it is in Mellanox firmware tools). I wouldn't be too shy about just literally grabbing 100% of the 100G firmware and flashing that without double-checking...

Hi All, Does anyone know whether recent QLogic drivers are able to work on Windows 10? Typically drivers are fairly compatible between Windows 10 and Windows Server 2016/2019 (e.g. Mellanox drivers work fine) - but QLogic appears to fail to start in qebdrv: Device...

Since actual computer power supplies run on single phase, 3-phase is really only "good" for a few things for an end-user: 1. Saving on wiring - you can run more current through a smaller gauge wire / less copper. 2. Redundancy - if you lose just one phase you still have some operational...

I don't think it's a good deal at all. Even at this highly discounted price, the performance and power usage are both worse than two socket Epyc systems and similar to older 4 socket Xeon systems, both of which cost less.

I have DL380 G9 rails if you haven't located any yet.

These aren't just any old CPUs...

This is exciting (though have also invested heavily in Tesla/etc. cards in the meanwhile when this was not possible, so it's less exciting than it would have been a couple of years ago!)
