PowerProtect Data Manager 19.12 Deployment Guide

The following table indicates the default amount of memory assigned to the PowerProtect Data Manager virtual machine in a standard environment. The default values are the minimum recommended values.

The recommended number of cores is 14. Also consider the following:

• Depending on the environment, increasing the amount of memory can increase performance.
• If low-memory alerts are seen, increase the amount of memory.
• Do not increase the amount of memory beyond 32 GB of RAM. PowerProtect Data Manager is not designed to support more than 32 GB of RAM.
• If you are deploying PowerProtect Data Manager to a virtual machine in a cloud Marketplace environment, it is automatically assigned 32 GB of RAM. This amount of memory should not be changed after it is deployed.
• Most of the services from PowerProtect Data Manager are memory intensive. When the available physical memory drops to a certain threshold value, these services start leveraging swap memory. If swap memory resides on a slow disk, then there can be significant impact on the Java Garbage Collection activity from each of these services when memory that has not been recently used needs to be swapped into physical memory.

  Therefore, it is highly recommended to configure swap memory on a solid-state drive (SSD). During deployment of the PowerProtect Data Manager server, use the SSD data store to avoid the high latency disk impact from swap and metadata operations.

Memory and updating from an earlier version of PowerProtect Data Manager

Features in the current version of PowerProtect Data Manager might require more memory than required in previous versions. When updating from an earlier version of PowerProtect Data Manager, ensure that you increase the amount of assigned memory as necessary.
