IBM Power6 Midrange Server

IBM Power 550 (8204-E8A)

You have a Power 550 8204-E8A. Here's what that means in 2026: IBM's step-up midrange Power6 server, out of standard IBM support since March 2019.

Machine type: 8204-E8A Software tier: P10, P20

The Power 550 (8204-E8A) was IBM's step-up midrange Power6 server, scaling to 8 cores for commercial IBM i, AIX, and Linux workloads that had outgrown an entry-level Power 520 but didn't need the Power 570's multi-drawer scalability.
