    Hard-disk space 200GB for database 600 GB 1 TB SATA hard disk
    Operating System 64 bit 64 bit 64 bit


    Please note that change in flow rate will lead to change in system requirements as below: 

    Rate of Flow/Second Processor RAM Disk space for Aggregate Data (Forever) Additional Disk space for RawData (Optional) Server Type

    0 to 3000

    2.4 GHz Quad Core Processor 4 GB
    200 GB 75 GB/Day -

    3000 to 6000

    3.2 GHz Quad Core Processor 6 GB 200 GB 150GB/Day 64 bit

    6000 to 9000

    3.2 GHz Quad Core Processor 8 GB 200 GB 225GB/Day 64 bit

    9000 to 10000

    3.2 GHz Quad Core Processor 16 GB 200 GB 250GB/Day 64 bit

    100k (With Raw Data)

    2 x 3.2 GHz Quad Core Processor 48 GB+ 350 GB 1.5TB/Day 64 bit

    * HighPerf addon is recommended if the number of flows is >10k.
    * Aggregated data is calculated based on the top 100 records.


    For the device exporting NetFlow, ensure that the NetFlow export version format is exactly the same as the Cisco NetFlow version 5 or version 7 or version 9 format. For information on Cisco devices and IOS versions supporting Netflow, consult the Cisco NetFlow Device Support table.
