Want to run something other than Linux on a ARM 64-bit server? Soon you can: a small software company has shown FreeBSD running on a 96-core server.
Semihalf, which is based in Poland, demonstrated a beta version of FreeBSD running on a server board built with Cavium's ThunderX processors. That's the first hardware based on ARM's 64-bit processors to run FreeBSD.
FreeBSD is a flavor of the Unix OS developed by the University of California, Berkeley. The OS runs on a broad array of platforms.
