    The latter manages to combine four of the processors with up to 512GB of RAM for a 128-core, 512-thread monster.
    16 x 4 != 128

    Although 16 x 4 x 8 == 512, so I assume it is just a typo

    Each core is capable of 8 simultaneous threads so 4 processors x 16 cores x 8 threads = 512 threads!

    Yes, hence my statement that 16 x 4 x 8 == 512. My point was that a 4 processor server would have 64 cores, not 128 as stated in the article

    Is that all - sheesh!

    IBM Power 795 = 8 processor books, each with 32 cores - so that's 256 cores. And with their simultaneous multi-threading that's up to 4 threads per core. So that's potentially 1,024 threads! Oh, and these puppies run at 4GHz rather than 1.65GHz that the T3's reach.

    Details are given in http://www.redbooks.ibm.com/abstract...4640.html?Open if you're interested.

    Okay, the 795 probably costs as much as half a housing estate, and is a full rack to itself rather than slotting alongside other kit like the T3 kit will. On the other hand, the IBM gear IS pretty neat - the RAS and virtualization stuff especially - and it runs Linux too if you want (RHEL and SLES fully supported!). And best of all ... you don't have to deal with Oracle.

    Apologies for bigging up Big Blue, but I've got to give 'em credit where due. Even if they are the main competitor to my employer!

    Career status: still enjoying my new career in DevOps, but it's keeping me busy...
