Maintain Power8
Third-party maintenance, replacement parts, used hardware sourcing, and firmware and backup planning for keeping IBM Power8 running past IBM's own support window.
Every current IBM Power8 model is past IBM's own end-of-support date ... but that does not mean the hardware stops working, and it does not mean you have to migrate immediately. A large, established third-party maintenance (TPM) industry exists specifically to keep Power8 systems running with vendor-backed support after IBM walks away. This page covers what that actually involves.
Third-party maintenance (TPM)
Once IBM's standard support ends, IBM stops providing hardware maintenance, machine code updates, and security patches for that model ... but independent TPM providers step in with parts, break-fix support, and monitoring contracts. Providers active in the IBM Power space include organizations like Service Express, Curvature, Evernex, and OSI Global, alongside AS/400 and IBM i-focused resellers such as Midland Information Systems that combine parts sourcing with support.
This is the critical limitation of TPM: it keeps the physical hardware running, but it does not restore IBM's software and firmware patch stream. A TPM contract buys you time on the hardware side of the equation, not the software side.
Replacement parts and used hardware sourcing
A healthy secondary market exists for Power8 hardware: resellers such as ALTA Technologies, Midland Information Systems, Essential Technologies, and Flagship Technologies carry used and refurbished S812, S814, S824, and enterprise-tier systems, along with pulled parts for repair. If you are extending the life of an existing system rather than replacing it outright, sourcing spare processor books, memory CDIMMs, or drive backplanes from the used market alongside a TPM contract is a common combination.
Memory and storage upgrades
Within the ceiling of your specific model (see your model's directory page for its exact memory maximum), adding memory or internal storage capacity is still possible using the same DDR3/DDR4 CDIMM and SAS/NVMe components IBM originally shipped for that model. These parts are sourced from the same used-hardware and TPM-adjacent resellers, since IBM no longer sells new components for Power8.
Firmware considerations
IBM's own firmware (system microcode) updates for Power8 stopped at each model's end-of-support date. Any firmware-level security vulnerability disclosed after that date will not be patched by IBM on Power8 hardware ... this is a real, not theoretical, exposure. See our end-of-support and risk page for what this means in practice.
Backup, HA, and DR on Power8
If you are extending Power8's life, treat backup and disaster-recovery posture as non-negotiable, not optional. With IBM no longer shipping parts or firmware fixes, an unrecoverable hardware failure is a real business risk, not a hypothetical one. At minimum: verify your IBM i save strategy (full system saves, not just library saves) is current and tested; confirm any PowerHA or logical replication setup does not depend on a second unsupported Power8 system as its only failover target; and keep an offline, verified backup path that does not assume the primary Power8 system will always be reachable.
If your maintenance plan is 'keep it running for now,' pair it with a firm internal decision date. Open our end-of-support and risk page for what staying past that date actually costs, and our migration options page when you are ready to plan the replacement.
