Heck, Dell will sell you a 4U rack-mount with 3T in it.  Got probably a half-dozen
of them across the hall from my office for the HPC people.  And we probably got
a hundred or so nodes with 512G of RAM across the various clusters.

And IBM will sell you a System/Z Z14 with 32T of memory, and crazy amounts of
I/O capability (Imagine the equivalent of 320 PCI slots....)

And yes, it will run Linux, it's a s390 architecture box.
