Power 9 Linux upgrades by current model

Your current Power 9 model and Linux workload

Power 9 meets the RHEL 9 processor baseline but not the Power 10 baseline for RHEL 10 or SLES 16. Canonical supports Power 9 in Ubuntu 22.04 LTS and later eligible releases.

Choose the exact catalog identity below for its planning notes. The list identifies assessment starting points; eligibility still depends on the installed edition and configuration.

AC922 8335-GTC: keep accelerator dependencies with the application

Record GPU or accelerator features and their driver/runtime versions. Confirm whether the workload requires NVLink, a specific CUDA build or a certified analytics stack. A newer general-purpose Power server is not automatically an equivalent accelerator platform.

The catalog’s storage and I/O context is Confirm drive and accelerator carrier configuration. Check the installed adapters and recovery devices against the destination; their presence on the source does not establish reuse eligibility.

Record the distribution’s full release and the output of uname -m. Then match the package architecture and boot arrangement to the Power Linux architecture guide.

Choose the destination from the application or appliance certification first. Request a model comparison after the required accelerator and software combination has been established.

Your installed Linux release on Power 9

Separate PowerVM servers from OpenPOWER, accelerator and Linux-only variants. The target’s boot firmware, hypervisor and application certification still control.

Find the installed release information.

Upgrade Linux or add capacity on Power 9

Start with the application result you need. A supported OS change can keep the existing server useful; a capacity change can address resource pressure. Neither establishes a supported release on hardware the vendor excludes.

• Compare processor allocations with measured Linux workload demand.
• Review memory capacity separately from processor demand.
• Review the Linux release guide for the installed level and desired destination.
• Ask Midland to compare an OS/capacity upgrade with replacement.

Migration from your Power 9 Linux system

Moving to another server is a separate task from updating the OS. The plan must qualify the destination, transfer the workload and prove the application works before the final switch.

1. Record the source configuration.
2. Choose a compatible transfer method.
3. Rehearse application recovery and acceptance.
4. Agree the rollback decision before new production transactions begin.
