The IBM Services Virtual Summit is an end-to-end digital conference with Technology Stands, exclusive Networking Opportunities and Keynote Presentations on how to reinvent your business with AI and Hybrid Multi-Cloud. Join this unique learning experience today and enjoy a full virtual event from the comfort of your desk. Intel® Optane™ persistent memory (PMem) has some similarities with DRAM in the following ways: Packaged in DIMMS, resides on the same bus/channels as DRAM, and can act in the same way as DRAM storing volatile data. Where Intel® Optane™ persistent memory (PMem) differs with DRAM is that it offers many new and exciting features.

The Zing Or, you have selected values that are too aggressive using the wizard or directly in the pmem.conf&n The machine types include both Compute Engine virtual machines (VMs) and Bare Metal Solution bare-metal machines. Except where noted in the table, SAP Apr 1, 2019 drive to form a virtual memory pool along with the host system's DRAM. IBM, and Microsoft, and scale-out memory-centric architectures like checker or increase yarn.nodemanager.vmem-pmem-ratio to a relatively larger value. That page had a link to a very useful page from IBM: And although huge amounts of virtual memory being allocated isn't the end of the Boost Performance with Data Persistence.

Likewise, the capability known as Virtual Persistent Memory (PMEM) is also exclusive to POWER9. Update 01/18/2020: Added IBM POWER9 PMEM support and updated table to reflect RHEL for SAP HANA has been grandfathered by RHEL for SAP Solutions. Update 01/27/2021 : RHEL 8.2 for SAP Solutions (Virtual PMEM) for SAP HANA on IBM Power Systems Over the next two to three years, there will be a broad range of new memory technologies that are designed to disrupt the industry, providing persistence characteristics with a range of performance and cost advantages to benefit in-memory 2020-05-03 PMem can be consumed in one of two methods: Virtual PMem (vPMem) - In this mode, the GuestOS is actually PMem-aware and can consume the physical PMem device on the ESXi host as standard, byte-addressable memory. In addition to using an OS that supports PMem, you will also need to ensure that the VM is running the latest Virtual Hardware 14 2019-05-16 PMem-aware VMs can have direct access to persistent memory.

Virtual PMEM will significantly reduce the shut down and start-up time of the database compared to disk-based reloads from storage. This significantly improves serviceability for SAP HANA and Linux software maintenance, in particular for large-scale databases.

If a current memory usage or average memory usage value that is shown in the system table is displayed in a red box, the value exceeds a configured threshold. What is Virtual Persistent Memory? This is an enhancement in advanced Virtualization platform (PowerVM) available only on IBM Power Systems for SAP HANA that introduces the ability to configure persistent volumes using the existing DRAM available on the system. IBM has introduced a new capability called Virtual Persistent Memory (PMEM) in the virtualization platform (IBM PowerVM) of IBM Power Systems. This will address the following business requirements that clients have shared with us: DRAM backed Persistent Memory or Virtual Persistent Memory (vPMEM) volumes for faster partition restarts With this support (FW940 is required), you can carve part of memory as virtual persistent memory volumes and assign it to partitions which can leverage PMEM for faster restarts. Virtual PMEM does not preserve memory across server power down. But it will preserve the data if you reboot your HANA, Linux OS Specific deployment ratio needs to be followed between DRAM and PMEM when configuring HANA database.
