Capacity Planning for LTM + ASM

We hve pair of BIG-IP 6900 and I need to do some capacity planning for it. Is there any F5 tool or formula available to predict expected CPU/memory load on F5 by feeding following parameters.



Number of i-rules


ASM Policy for HTTP/XML


Active connections


New connections / sec (Client)


Throughput (bits)Client Throughput (bits)Server


Throughput (packets)


HTTP requests SSL trans/sec


Average Packet Size

  • I don't think there is an online tool that is available because, the CPU and memory utilization's are not only effected by the number of policies, rules, but also by the complexity of the policies/rules and the frequency at which they are utilized. I would suggest contacting your sales rep would be a better option as they know your environment better from the F5 capabilities perspective.
