I was working at <big server OEM> back in 2009, and they were just preparing to introduce a new massive 8-way server that had 64 RAM sockets. Loaded on up with (then-brand-new) 32 GB DIMMs - for 2 TB of RAM. Only had 64 GB of storage! (One 64 GB SSD.)
Our memory order from Micron was over $1 million. They threw in a USB flash drive. :-D (I seem to recall the DIMMs were somewhere north of $2000 each, and we ordered a few servers' worth.)
Indeed this is the right place for this antiquated photograph.
My new workstation can take upto 2TB of RAM and using far fewer slots than shown above.
That board supports 2TB in 16 slots. I dont think I've seen 128gb dimms.
Was this Xeon 7500 (Nehalem-EX)?
It was indeed! We were prepping them for full production, and my team was in charge of getting some pre-production systems ready for demos, sending to software OEMs for testing, etc. So of course we had to do a "completely full" system, out of sheer curiosity.
