IBM POWER9 scale-out servers deliver more memory, better price performance vs. Intel x86
IBM recently began shipping its next-generation Power Systems servers incorporating its newly-designed POWER9 processor. These POWER9-based scale-out systems, including S914, S922, S924, H922, H924 and L922, provide leadership capabilities in non-accelerated compute spaces such as in-memory databases, advanced analytics and cloud environments.
POWER9 scale-out servers are cloud-ready and include built-in PowerVM virtualization capabilities, enabling you to deploy the cloud environment to meet your organization’s changing business needs. POWER9 scale-out servers for IBM i, AIX and Linux easily integrate into your organization’s cloud and AI strategy, while delivering the performance and RAS needed for your mission-critical workloads like Db2 and Oracle. IBM also offers POWER9 scale-out servers built and optimized for SAP HANA®, boasting a memory footprint of up to 4TB in a 2U form factor for gaining insights faster while delivering superior reliability and performance.
These new systems incorporate our latest I/O technology, including 25 GB/sec high-speed interconnect for CAPI and OpenCAPI along with embedded PCI-Express 4.0 connectivity which doubles the I/O bandwidth versus PCI-Express 3.0 .
POWER9 2-socket systems provide up to 4TB of memory, 33 percent more than compared Intel x86 Xeon systems , delivering additional benefit to in-memory databases such as SAP HANA.
POWER9 continues in the tradition of previous generations by delivering improved per core performance capabilities compared to its predecessor. When compared to similar POWER8 systems, POWER9 delivers 1.25-1.5X per core the performance capability, enabling clients to further reduce software spending on stacks that are licensed per core . This focus on core architecture and capabilities delivers over 2X the per-core performance over compared x86 systems across a wide range of benchmarks .
The focus has not been just on performance, but also delivering value to clients in the form of cost reductions. The L922 delivers 2.4X the price performance over compared Intel x86 systems in database and advanced analytics environments such as Db2 Warehouse .
