    I love NIM. I rely on NIM when I'm doing new server builds, and it's also my go-to for installing the VIO server.

    Other Options for Volume Group Backups

    How do you backup your volume groups? These days we're often dealing with snapshots on a SAN, but there are still occasions when you want to backup to a local tape drive, a file, or a NIM server. The specifics depend upon the amount of data and the type of infrastructure we're dealing with. (Obviously moving terabytes across a 100mb network isn't the best way to go.)

    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). The E980 is the follow-on to both the E870 and E880, and delivers 1.5X the performance. 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.

    Techspeak Explained

    You don't need me to tell you that there are a lot of acronyms in tech. But it never hurts to be reminded that more and more workers are entering the world of AIX and IBM Power Systems from non-UNIX and/or non-IBM backgrounds. As a consultant, I regularly meet people who are new to IBM systems and unfamiliar with many IBM-specific terms--e.g., PMR, APAR, NIM, WPAR, VPD and SEA--that we take for granted.
