Fujitsu had already built SuperSPARC-based supercomputers, and Oracle recently ported their Red Hat clone to AArch64 (no legacy 32-bit or Thumb) and produced an ISO for the PI-3.
The link I posted was Fujitsu's new ARM server, which bundles 32GB of RAM and over 30 cores on a single die. These are deployed in dual-socket blades attached to the "tofu" routing that they scavenged from their SPARC supercomputer.
Fujitsu is saying that their ARM implementation is the fastest server processor available, ahead of Intel.
