Hardware
The hardware requirements of the OPC Classic extractor depend on the configuration and server size.
Memory
The extractor replicates the entire server in memory, and will buffer up to a few minutes of data points and events at a time. Running the extractor against a small server should take no more than 100 MB of memory, while running against a larger server (>100k tags) might take as much as 2-3 GB. If the server is relatively small, a VM with a single core and 1 GB of memory should be sufficient.
CPU
For most cases, a single CPU core is sufficient for the extractor.
Software
The extractor must run on a Windows machine with COM+ enabled.
Storage
The extractor writes log files to disk. This should usually not take up much space.
