Orca™ eMail Archiver model OEABF1000 will last our example client approximately 7 years and 10 months.
  • Calculate Client's Usage Rate
    1. Client's mail server has 250 users
    2. An average user gets 140 emails per day
    3. Average email size is 25KB(0.0000238 GB)
    4. This client will use (users * emails per day * email size bytes * 0.30 compression&de-duplication factor * 365 days/year), or 91 GB of storage per year
  • Calculate Storage Available for Emails
    1. Total storage space = 1,000 GB
    2. OS/filesystem overhead = 11% or 110 GB
    3. Available storage from factory = total - overhead = 890 GB
    4. 20% of each Orca™ eMail Archiver is dedicated to DB entries and message indexing
    5. Truly available storage = storage from factory - message indexing or 712 GB
  • Calculate Time Until Machine is Full
    1. (available storage / storage per year) = 7.792 years or 7 years 10 months until full
