    Hi,

    Someone could answer the Sizing for those criteria bellow and if the SMG is capable to do messages analisys :
    Number Of User : 5,000
    Number (average) of inbound email received / day: 300,000
    Number (average) of outbound email sent / day: 100,000
    Estimate % of spam received / day: 90%
    The SMG will be the MX in this organization
    The Organization will use the quarantining for Spam and suspect spam
    Only one Site receive the inbound email
    They require redundancy and high availability
    For 5 year the forecast volume will be increased, about 5% each year.

    Regards,

    Alexsander

    Hello Alexsander,

    Symantec provides to its employees and partners a sizing tool that can estimate the necessary number of SMG appliances (either physical or virtual) based in some criteria. Here are some of the information needed, for example:

    - Number of users

    - Average number of incoming / outgoing messages per day

    - Estimative of the percentage of Spam received

    - Estimative of increase in email volume per year

    - High Availability and / or Disaster Recovery needs

     

    Based on the figures you have posted, it's fairly easy to SMG to handle this email volume. As a result from inputing them in our sizing tool, it comes out with the following recommendation:

    - One (1) Control Center, Virtual Edition, with 4 CPU Cores, 8Gb of RAM. Please allocate at least 300Gb of Virtual Hard Disk. You should plan the space needed for the Virtual Disk based on quarantine usage/retention, log retention, frequency of backups. All backups are created locally and then transfered to a location out-of-the-box.

    - Two (2) Scanners, Virtual Edition, with 4 CPU Cores, 4 Gb of RAM. Please allocate at least 90Gb for each scanner. This will be enought space to handle local queues, logs and updates.

    Please let me know if you have further doubts.
