    The POWER9 System Roll-Out Continues

    Today IBM is announcing two new POWER9-based enterprise systems: the E950 (9040-MR9) and the E980 (9080-M9S).

Rather than have two high-end machines, as was the case in POWER8 (and going back to POWER7 with the 770/780), those systems are collapsed into the E980. As for the E950, with its available cores and memory, it packs quite a punch for a 4-socket server, as you'll soon see.

    AIX Implementation Best Practices Updated for POWER9

    An updated version of AIX implementation best practices for commercial workloads was released in May. This should not be confused with the POWER9 performance best practices document I referenced three weeks ago. In this case, I'm talking about the latest in Fredrik Lundholm's popular series of presentations.
