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.
|Model||Processor offerings||OS support||Maximum memory capacity||I/O|
|AC922||Two sockets with 16 or 20 cores per socket||Linux||2 TB||Four PCIe Gen4 slots|
|LC921||One or two sockets with 16 or 20 cores per socket||Linux||2 TB||Four PCIe Gen4 slots|
|LC922||Two sockets with 16, 20 or 22 cores per socket||Linux||2 TB||Six PCIe Gen4 slots|
|Multiple OS boxes|
|E950||Two or four sockets with 8, 10, 11 or 12 cores per socket||AIX and Linux||16 TB||Ten PCIe Gen4 slots; one Gen3 slot|
|E980||Up to four nodes with 4 sockets per node; 8, 10, 11 or 12 cores per socket||AIX, IBM i and Linux||64 TB (max of 16 TB per node)||Max of 32 PCIe Gen4 slots (8 slots per node)|
|S924||Two sockets with eight, 10 or 12 cores per socket||AIX, IBM i and Linux||4 TB (2X the S824 memory capacity)||Five PCIe Gen4 slots; six PCIe Gen3 slots|
|S922||One or two sockets with four, eight or 10 cores per socket||AIX, IBM i and Linux (Note: The four-core model doesn’t support IBM i. All other S922 models support IBM i with a limit of four cores per partition.)||4 TB (4x the memory capacity of the S822)||Five PCIe Gen4 slots; four PCIe Gen3 slots|
|S914||One socket with four, six or eight cores per socket||AIX, IBM i and Linux||1 TB||Two PCIe Gen4 slots; six PCIe Gen3 slots Limitation: The four-core model doesn’t support PCIe expansion or internal disk drawers. Note: The S914 has a tower model that includes 110 VAC.|
|L922||One or two sockets with eight, 10 or 12 cores per socket||Linux with PowerVM only; bare metal and other KVMs not currently supported||4 TB (4x the memory capacity of the S822L)||Five PCIe Gen4 slots; four PCIe Gen3 slots|
|SAP HANA boxes|
|H924||Two sockets with eight, 10 or 12 cores per socket||Linux; AIX and IBM i limited to 25 percent core activations||4 TB||Five PCIe Gen4 slots; six PCIe Gen3 slots|
|H922||One or two sockets with four, eight or 10 cores per socket||Linux. AIX and IBM i limited to 25 percent core activations||4 TB||Five PCIe Gen4 slots; four PCIe Gen3 slots.|
