What specification servers are required will depend very much on your use case. The numbers of documents you want to process at once, their size and content type (an OCR requirement in particular will add considerable processing time for the ingest step) and the number of operations you want to run on those documents. The testing we've done that is commented on below should suffice to give an indication

The testing we've done that is commented on below should suffice to give an indication of what specification you might need given budget constraints versus desired performance.
The S&D demo servers are low level KVM VMs running in the same datacentre, with the Ingest server running 2 vCPUs and 1G RAM and the frontend server running 2vCPUs and 2G RAM, with host servers running multi-core Xeons. In our tests of bulk operation (which is via the CLI tool as documented here https://git.law/newroco/searchanddisplace-core/src/branch/master/demo-cli/README.md) using those demo servers we got the following results.
