POWER 9 Hardware at a Glance

Beginning in late 2017, IBM unveiled new Power Systems servers that utilize the POWER9 processor. The AC922―the only model with built-in GPUs―is designed for enterprise AI workloads.

Other offerings support Big Data analytics workloads (models LC921 and LC922) and Linux-only workloads (each of the L Models, including the L922), and smaller, mission-critical workloads and private clouds (models S914, S922, S924).

The H models (H922 and H924) share the same hardware as the S922 and S924 but are marketed specifically for SAP HANA installations.

And, of course, enterprise-class systems with increased capacity, features and reliability, availability and serviceability (RAS) characteristics (models E950 and E980) are also available.

All of this technology supports the diverse needs of Power Systems clients. Check out the specs for all of the POWER9 hardware in this handy photo guide.
