Before you order EJ1M

The drive bay and controller setup decides how many drives the server can hold and how they are protected. Changing it usually means planning downtime, so check it against your machine type first.

Not sure which Power 9 you have? The Power 9 machine types page shows how to check. Collecting several parts for one quote? Use the Power 9 quote checklist. Or look up another feature code.

Source: IBM Docs: PCIe3 x8 cache SAS RAID internal adapter 6 Gb (FC EJ1D and EJ1M; CCIN 57D8); REDP-5497 section 2.6.4. Always confirm against your server's own configuration before you order.

Your 4 next moves with a Power 9

Every Power 9 owner lands on one of these. You can mix them, too. Keeping or upgrading buys time while you plan a replacement.

  1. Keep it running

    Your Power 9 does not stop working when IBM support ends. Third-party maintenance can cover parts and repairs, often for less than IBM charged.

    Best when the server is stable and you need one or two more years.

    Compare third-party maintenance

  2. You are reading about this move

    Upgrade the server you have

    More memory, bigger drives, or a faster network or Fibre Channel card can buy real time without a new server. Every part has an IBM feature code, so the upgrade starts there.

    Best when you are running out of room, not out of support.

    Browse Power 9 upgrades

  3. Buy a used or refurbished Power 9

    A matching used Power 9 makes a cheap spare, test box, or short bridge. Match the machine type first, because an A model and a G model carry different support dates.

    Best for a spare, a test system, or a stopgap of two years or less.

    Compare new, used, and refurbished

  4. Replace it with Power 10 or Power 11

    If you need IBM i 7.6, or want five or more years of IBM support, price a replacement. IBM i 7.6 does not run on any Power 9.

    Best when the server has to last past 2027 or the software needs a newer release.
