# System Requirements

The following table provides the minimum and recommended hardware specifications for running Media Server. The recommended specifications are only a guide, because actual requirements depend on the data that is being ingested and the processing tasks that you configure.

Component | Minimum | Recommended
--- | --- | ---
CPU | The minimum number of CPU cores can be calculated as follows: Number of concurrent `process` actions x (1 core for ingest + 1 core for continuous encoding + 1 core for each analysis task ) + 1 Continuous encoding is defined as encoding every frame, for example to a rolling buffer. To ingest video from four cameras simultaneously, run three analysis tasks on each stream, and encode video from each camera into a rolling buffer, the server should have a minimum of: 4 x (1 + 1 + 3) + 1 = 21 cores. To ingest video from four cameras simultaneously, run three analysis tasks on each stream, but encode only result images, the server should have a minimum of: 4 x (1 + 0 + 3) + 1 = 17 cores. | OpenText recommends Intel Xeon CPUs, because Media Server has been optimized for Intel processors.
Memory | 4 GB | 16 GB
GPU |  | See GPU Requirements
Disk space | 6 GB for the Media Server installation. The common speech-to-text resources are approximately 13.5 GB. Additional legacy language packs are approximately 500MB each. Speech-to-text resources are available as separate downloads and are not included in the Media Server package. | A large amount of free disk space is required to encode images or video to disk.

If you deploy multiple Media Servers across multiple machines, ensure that all of the machines synchronize their clocks with a time server.

## Software Dependencies

When you start Media Server, the `libs/torch` directory must be on the `PATH` (Windows) or `LD_LIBRARY_PATH` (Linux). OpenText recommends installing Media Server as a service. On Linux `LD_LIBRARY_PATH` is set by the service configuration or start script automatically, so if you install Media Server as a service no further action is required. On Windows, set the `PATH` environment variable for the user that runs the Media Server service, such that it includes the `libs\torch` directory.

Java is required by File Content Extraction to ingest some file types on Linux platforms. You can use Java 8 to 17.

## Antivirus Recommendations

If you are running antivirus software on the Media Server host machine, you must ensure for performance reasons that it does not monitor the Media Server directories.

Some advanced antivirus software can scan the network and might block some Media Server traffic, which can cause errors. Where possible, exempt the Media Server processes from this kind of network traffic analysis.
