    Description

      I am currently working on sizing a mongodb cluster. I am taking into the following considerations for sizing. Please let me know if i missed any:

      1) Anticipated Size of the data(Number of documents * Size of documents * Number of users)
      2) Expected size of data to be replicated
      3) Size of Indexes(for each collection,5% of data size if default "_id" index, 5% for each additional index on each collection)
      4) Size of the working set(to determine size of RAM)
      5) Data archival requirements

      Let me know if there are additional things i need to consider.

      Also, is there a guideline on the number of shards to be designed for a cluster?

      Thanks,
      Yash
