Memory Use, Meta-Data Caches

If you are planning to make a substantial change, such as loading databases with a large number of indexes from another server, use sp_helpconfig to calculate an estimated metadata cache size. sp_helpconfig displays the amount of memory required for a given number of metadata descriptors, as well as the number of descriptors that can be accommodated by a given amount of memory. An index metadata descriptor represents the state of an index while it is in use or cached between uses.
