Sparc T4-4

Anyone got any experience with these at all (business related not for crunching! though I wish)

They have up to 4 cpu's with 8 cores each and 8 threads per core.

I've had some quotes from people at work for one of these where they carve it up into VM's but for a Production DB server (oracle) it is only a single core with 128Gb Ram and for app servers, 1 core with 16Gb ram.

Now traditionally in the past I would have used a single CPU perhaps for an app server with 8 cores or at least 4 cores and double for the DB server, but I'm just not sure on the threading efficiency of these things.
