IBM Support in Nigeria After End of Life

Core Banking on IBM Power in Nigeria, Long After the Support Date

A significant share of Nigerian core banking still runs on IBM Power under AIX. These are not legacy systems in the dismissive sense — they clear transactions for millions of customers every day and they do it reliably. What they are is unsupported, because IBM's withdrawal dates arrived years ago and replacing a core banking platform is a decade-long conversation, not a procurement cycle.

The catalogue defeats teams before availability does

The most common reason a Nigerian bank believes an IBM part cannot be sourced is that the FRU it is searching belongs to a different machine type. IBM's numbering is unforgiving, institutional knowledge leaves with the engineer who had it, and the vendor quoting the part has no incentive to correct the search. We start from the machine type and model, which converts most declared-obsolete requests into an ordinary order.

Lead time makes stocking the strategy

Delivery to Lagos, Abuja or Port Harcourt runs five to seven days per our published shipping times, with customs clearance adding one to three. For a platform clearing transactions, that is not an outage plan. We size an on-site spares holding against the specific frames in service — memory, power supplies, fans and disks — so the failures that actually occur are covered locally.

Knowledge leaves before the hardware does

The hardest part of supporting IBM Power in Nigeria is rarely the machine. It is that the engineer who understood the frame moved to another bank four years ago, the documentation was never updated, and the remaining team inherited a system they are responsible for but did not design. We work from what the machine reports about itself rather than from institutional memory, because the memory is usually gone.

Planning around the naira

Dollar-quoted parts and a moving exchange rate make open-ended maintenance uncomfortable for Nigerian finance teams. We quote firm, hold it for a stated period, and phase any stocking programme so the commitment is predictable. For a bank weighing a core replacement against another two years on the existing frames, that predictability is often the deciding factor.
