There is a direct correlation between the size of memory and the size needed for a page file while running applications. If the system drive storage is SSD you can leave the page file residing there, and set the starting size of the page file base on the amount RAM x 1.5. 2. However, today’s SSD are rated to transfer 20 GB+ of data daily for 5-years and often have a MTBF of 1,000,000 hours, which is well beyond what the average user does on their computer. [email protected] ". And all you think is correct, there are people that suggest using an HDD as a second drive for a page file, reducing the overall read/writes done to the SSD, and extending the life of the drive.

I would spend more time on making sure the components of the application are installed optimally than worrying about the pagefile (unless you plan to underconfigure the memory). We will install SAP in the Guest Server, according to SAP Guide, we need to assign at least 48GB Page file in the Guest Server, 5. Program files, i.e. I don't think it hurts having a page file just in case. My monitoring shows that the pagefile has been at 4GB since the VM was created in April, it has never increased beyond 4GB nor has it decreased.
