Server CPU and RAM requirements
Power Management software needs to be installed on dedicated machines, so that other non-Power Management software applications do not consume machine resources.
When selecting server hardware, carefully review the PassMark® score and CPU Clock Speed. The required processor is defined according to an average CPU mark given by PassMark Software. To check CPU performance, for example a Core i3 CPU, type "PassMark Core i3" in the search engine of a web browser. This will return the CPU's calculated performance as compared to other similar well-known processors.
CPU and RAM recommendations for various system architectures
- The requirements listed in this topic are minimum requirements; we recommend that you consider doubling the RAM requirements listed.
- Power SCADA Anywhere server must have a CPU with SSE2 instruction set support.
Power Operation server (medium and large systems)
The following table lists the number of CPU cores and RAM required for a Power Operation system.
NOTE: Use the tag or device number that is higher of the two numbers. For example, if you have a system using 120,000 tags with 300 devices, use six CPU cores and 16 GB of RAM.
NOTE: These are minimum requirements. We recommend that you consider doubling the RAM requirements listed.
| Use the larger figure below | CPU PassMark Score | # CPU Cores | RAM (GB) |
|---|---|---|---|
| 1,500 tags or 50 devices | 2,000 | 2 | 8 |
| 15,000 tags or 100 devices | 4,500 | 4 | 16 |
| 50,000 tags or 200 devices | 8,000 | 6 | 16 |
| 100,000 tags or 400 devices | 8,000 | 6 | 16 |
| 150,000 tags or 600 devices | 8,000 | 8 | 32 |
| 200,000 tags or 800 devices | 10,000 | 8 | 48 |
| 250,000 tags or 1,000 devices | 10,000 | 12 | 48 |
| 300,000 tags or 1,200 devices | 10,000 | 16 | 64 |
| 350,000 tags or 1,400 devices | 10,000 | 20 | 64 |
| 400,000 tags or 1,600 devices | 10,000 | 24 | 96 |
| 450,000 tags or 1,800 devices | 10,000 | 24 | 96 |
| 500,000 tags or 2,000 devices | 10,000 | 30 | 96 |
Power Operation and Power Monitoring Expert on the Same Machine
The following table lists the number of CPU cores and RAM required for a Power Operation and Power Monitoring Expert system on the same machine.
NOTE: Use the tag or device number that is higher of the 2 numbers. For example, if you have a system using 120,000 tags with 300 devices, use 16 CPU cores and 28 GB of RAM.
NOTE: These requirements are based on product testing at the factory. They are intended as recommendations on system sizing. However, some customers may find that based on their system's design or usage they require more or less resources than what is recommended by this guide.
| Use the larger figure below | CPU PassMark Score | # CPU Cores | RAM (GB) |
|---|---|---|---|
| 50,000 tags or 200 devices | 8,000 | 14 | 40 |
| 100,000 tags or 400 devices | 8,000 | 16 | 48 |
| 150,000 tags or 600 devices | 8,000 | 18 | 64 |
For systems greater than 150,000 tags or 600 devices, we recommend a distributed architecture with separate physical machines for Power Operation and Power Monitoring Expert.
Power Operation and Power Monitoring Expert on separate machines
