I have 384TB of ECC DDR4 across two blades with 4 CPUs for a combined core count of 96.
It powers a fully populated 192 disk solid state SAN.
I was told it was old and in need of replacing, but apparently now it’s worth more than the GDP of the UK.
Can’t afford to run it (or hear my thoughts when in the vicinity)… but I can sit atop it like a fucking dragon.
And I will.
@SecurityWriter 384TB of RAM is a lot. Perhaps you meant GB?

Don't Breath Fire !!!! you evil dragon !!!
@moppi @SecurityWriter we're not all like that

Hmm true. Makes it quite unlikely.
However I want to push back on one thing. It would still be theoretically possible, as PCIe fabrics and such also exist.
But yea, probably not then. I didn't do the math for the space requirements....
@agowa338 Also worth noting 128 GB DDR4 DIMMs are almost universally “load-reduced”, or LR-DIMMs. Those have significantly higher latency than normally expected from RAM, though still lower than persistent storage. For low-latency RAM, you’re generally limited to 64 GB per DIMM, so double everything.
Then you have the PCIe cabling. Each card needs at least two dedicated lanes, otherwise contention wrecks your latency and you may as well use flash. That’s 768 or 1536 twinax bundles.
Lots of RAM is possible, but it takes *bonkers* amounts of space and some very exotic hardware.

@SecurityWriter I never thought about quantifying the perching potential of my computer hardware ...
I have a physical treasure trove, of a sort!

@SecurityWriter I'm not gonna lie, I'm a little turned on.....
More than a little even.
