To configure Intel Optane Persistent Memory with the SAP HANA platform on VMware ESXi, follow the steps outlined in the "intel Optane Persistent Memory and SAP HANA Platform Configuration on VMware ESXi User Guide." Here is a summary of the steps:
1. Configure the server host for Intel Optane PMem using the BIOS. The exact steps will vary depending on the OEM vendor. Refer to the documentation provided by your vendor for specific instructions.
2. Create App Direct interleaved regions and verify their configuration for VMware ESXi use. This can be done through the OEM UEFI or BIOS menus, or using the VMware web client or esxcli command.
3. Create a VM with hardware version 19 (VMware vSphere 7.0 U2) with NVDIMMs and allow failover to another host.
4. Edit the VMX VM configuration file to make the NVDIMMs NUMA-aware. This step ensures optimal performance by aligning the VM and allocated Intel Optane PMem in the same NUMA node.
5. Create a file system on the namespace (DAX) devices in the guest OS. This step involves configuring the SAP HANA platform to use the persistent memory file system.
6. Restart SAP HANA to activate and start using Intel Optane PMem.
For detailed instructions and additional information, refer to the "intel Optane Persistent Memory and SAP HANA Platform Configuration on VMware ESXi User Guide.
