Maintain Power5

Third-party maintenance, replacement parts, and used hardware sourcing options for organizations that need more runway on Power5 before migrating.

If a full migration isn't happening this budget cycle, third-party maintenance (TPM) is how most organizations keep Power5 hardware running in the meantime. It should be treated as a bridge, not a permanent answer: parts for hardware this old are a diminishing supply, sourced from decommissioned units rather than manufactured new.

What third-party maintenance actually covers

Hardware break-fixOn-site or depot repair when a component fails, typically with a contracted response-time SLA

Parts sourcingReplacement components pulled from decommissioned Power5 systems; supply shrinks over time

Multi-vendor consolidationMany TPM providers bundle Power5 coverage with other aging data center hardware under one contract

What it does not coverNew IBM microcode updates, IBM i OS-level security patches, or any work IBM itself still performs

The honest math

At this point in the hardware's life, TPM cost curves typically bend upward as parts get scarcer, while a Power5 system's actual compute capacity is a fraction of what a current-generation Power server delivers per core. For most shops still on Power5 in 2026, the maintenance conversation and the migration conversation should happen at the same time, not sequentially.
