Creating an initial estimate of your database storage needs

Here's a way that you can do an initial but rough guess of your recommended storage needs. For a more detailed estimate, please refer to Guidelines for determining hardware configuration.

  • 1 MB per minute per Windows session with nominal activity

    You could need considerably more storage than this if sessions will include flash animation, video replay, and so forth.

  • Use a ratio of users to number of systems
    • For example, you could have 50 users for 1000 systems, which would be a 5% ratio; you would then multiply the number of users with the above estimates.
    • 50 Windows users would require 50 MB/minute, or 120 GB/week, or 1.5TB/quarter.
