Although Shawn is right about us not being able to answer properly, sometimes we can give qualified suggestions and guesses. At least to the direction you should be looking. The quality of the guesses goes up with the amount of information provided and "1TB" is really not much information. - Are you indexing while searching? How much? - How many documents in the index? - What is a typical query? What about faceting? - How many concurrent queries? - Expected median response time? > I'm building a SolrCloud cluster that may have approximately 1 TB of > data spread across the collections. We're running a 22TB SolrCloud of a single 16-core server with 256GB RAM. We've also had performance problems serving a 100GB index from a same-size machine. The one hardware advice I will give is to start with SSDs and scale from there. With present day price/performance, using spinning drives for anything IO-intensive makes little sense. - Toke Eskildsen
