Upgraded Compute Power for IBM Spectrum Fusion HCI

Big news! A new and more powerful compute node is now available for the IBM Spectrum Fusion HCI product! This new compute node provides double the number of cores and quadruple the amount of RAM compared to the original compute nodes that were released a year ago.

CPU and Memory

Like previous Spectrum Fusion HCI compute nodes, the new compute node is built upon a 1U Lenovo SR645 server.  The difference is that the two processor sockets inside are each populated with an AMD EPYC 7543 processor.  The EPYC 7543 is a 32-core, 64-thread processor that operates with a base clock speed of 2.8 GHz and comes with 256GB of cache.  With two of these processors, the server has a total of 64 cores and 128 threads available for running applications on Red Hat OpenShift.

The AMD 7543 processor is part of the AMD EYPC 3 processor family, sometimes referred to as the "Milan" family.  AMD says that EPYC 3 brings a 19% improvement to its instructions per clock (IPC) performance over its predecessor EPYC 2 "Rome" family.  And as with EPYC 2, EPYC 3 has support for PCIe Gen 4.  PCIe is the technology that is used to connect together the processor, storage drives, network interface cards, and other peripheral devices within the server.  Version 4 of PCIe is twice as fast as PCIe 3 and so it represents a major improvement in system performance.
