64GB is the maximum RAM physically supported by current Sun hardware (in
the UE10k).  I expect this to improve substantially in the next
generation.

16EB is 16 Exabytes, or 2 ** 64 (the exa prefix is 10 ** 18).  With 64-bit
pointers in the kernel this is the maximum possible memory that can be
addressed.  Not much of a limit at this point.
