IBM Power7 HPC Cluster Node

IBM Power 755 (8236-E8C)

You have a Power 755. Here's what that means in 2026: a 750-derived HPC cluster node, out of IBM hardware support since 2019, and rarely found running IBM i workloads.

Machine type: 8236-E8C

The Power 755 (8236-E8C) is a 750-derived, high-performance-computing-optimized Power7 cluster node: 32 cores across 4 sockets in the same general chassis as the 750, but tuned for compute density and cluster deployment rather than general-purpose commercial workloads. It is far less commonly encountered running IBM i in production than the 710-780 line, and its used market is correspondingly thinner.

If you have identified your system as a 755 rather than a general-purpose 750, its migration path and support considerations are the same as the rest of the Power7 line -- see our end-of-support and migration comparison pages -- but its used-market value and buyer pool are narrower, being HPC-specific.

A niche HPC-oriented system with a thinner used market than the general-purpose 750. Sourcing is typically through the same used-Power resellers that carry 750/755 inventory.

What IBM Power7 End of Support Actually Means

End of support is not a shutdown switch. Here is exactly what changed -- and what didn't -- when IBM Power7 passed its own end-of-service dates in 2019 and 2020.

Can Third-Party Maintenance Keep Power7 Running?

Third-party maintenance can cover Power7 parts and break-fix service while you prepare a replacement. It cannot restore IBM i fixes or new IBM machine code.
