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. (SAP Note 2786237) No ratio restriction applies using Virtual PMEM Intel Optane versus IBM Virtual PMEM –Major With the Virtual Persistent Memory solution the clients will have the ability to add persistency layer on their existing memory (DRAM), that will allow them to restart their environments by ~17X (based on IBM Internal testing) faster in case of any planned or unplanned maintenance work like HANA related patching, upgrades, OS related patching TID 7024300 “Hot plugging/unplugging of pmem memory having a size that is not in multiples of a specific size can lead to kernel panics” Summary. Virtual Persistent Memory is the latest tool in a long line of IBM and SUSE innovations to help customers get the most out of their SAP HANA on Power environments. IBM’s Virtual Persistent Memory is an enhancement in PowerVM that introduces the ability to configure persistent volumes using the existing DRAM technology.

Virtual Persistent Memory isn’t a new type of physical memory but is a way to use the PowerVM hypervisor to create persistent memory volumes out of the DRAM that is already installed on Case in point, in the latest IBM Power release – Virtual PMem is one of the key new features. With this feature customers can achieve fast restart of a workload – whether for planned downtime or unplanned outage without compromising ongoing performance during normal use.

On the one hand, TIMI means there already is a virtual layer between IBM i and hardware. Caching on PMEM: an Iterative Approach.

Virtual PMEM is included in all system and pool memory amounts. You can click the () icon next to some columns in the tables to change the contents of the columns. 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.
The firmware level that is used is AL730_087 for the IBM POWER7
At the same time, users need access to that data to drive business results. With IBM InfoSphere® Virtual Data Pipeline, users can instantly provision virtual database copies to work with near real-time data for data analytics, application testing, AI model training and testing, and data virtualization.
