Before you order EN0A

Fibre Channel cards connect the server to a storage network (SAN) or tape. Low profile cards fit the shorter 2U servers. Full height cards fit the taller 4U servers. If a card has a twin code, the twin is the same card in the other height.

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.

  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.

  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.
