Hi all, We are planning the replacement/migration from StorSimple to Azure File Sync as it's going EOL next year. So I know that there's a well trodden upgrade path and nicely documented (thanks MS). So we need to replace the SS hardware with some other storage device. We need to leverage the local caching functionality on recently accessed data as a must. But what I'm struggling to figure out is this: How do we calculate local caching storage requirements? I need to figure out how much disk storage we'll need. TIA. Mark.
