The smallest SPARC server that Sun/Oracle sells is the T5120. Those
have built-in encryption right on the CPU die, which I would hope
Symantec would take advantage of it by linking against libpkcs11.so.
Benchmarks have a single UltraSPARC-T2 doing 38.9 Gbit/s of AES-128:

Of course Fujitsu sells M3000, with SPARC64 processors, but they don't
have crypto AFAIK.
