The 32 bit OS can address 2^32 = 4 GB, the 64 bit OS
version can address 2^64 = 16,777,216 TB of RAM.

For UFS file system, the maximum size depends on the
amount of available RAM (for fsck). On amd64, you
can assume 2^64 * 32 kB blocks = 512 ZB.

For ZFS file systems, 2^128 = 256 ZB per pool are
possible, and 2^64 pools per system.
