Scalability questions to consider:

  • Number of devices

  • Number of flows per second

  • Storage retention Period

  • Local attached storage an not Network attached

Notes:

  • Larger then 200k flows per second requires distributed netflow servers

  • The CPU and RAM needs to be reserved at top priority (all the cores and memory)

  • Bandwidth between devices and Arbitrators needs to capable of data flows

  • The CPU an RAM needs to be reserved a top priority (all the cores and memory)
