I need to calculate hardware for SQL Server. The application is business data-driven application with 500 requests per second. We plan to buy server with 4 intel Xeon CPU and 64 Gb RAM. Is it sufficiently?

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. See the FAQ for guidance on how to improve it.

The specifications you've come up with looks like a decent start for "some kind of database" that you don't know much about. But you can get a very nasty surprise, finding out that this doesn't work at all. It's impossible to tell with the amount of information given. A query is not a fixed cost. If it was 500 light queries per second - you could scale down significantly. If they are really complex queries, you might need a lot more than you've specified. If it's a poorly written application, it might need a rewrite to be able to run decently fast. To best be able to answer this, you need to establish a good baseline for the application; How much resources does it consume under realistic load? The developers of the application should have some knowledge about this as well. You should also keep storage in mind - which needs to satisfy the throughput required, and have at least a basic level of redundancy to avoid data loss. I'm assuming you've got backup and high availability-concerns covered. | ||||
