Nimbostratusabout the module AsM
Dear all,
i have F5 2200 LTM, iwould like to know if i activate the module AMS how many percent can reduce teh perfermance of the f5 ltm?
who have some statistic about the consumption for the mo...

NimbostratusAFAIK, activating the ASM module itself won't add much if any load. The load increase will occur after you've built a policy and begin applying it to your VS's, also dependent upon the traffic level of those VS's. You can keep an eye on exactly how much ASM is adding under Security -> Reporting -> Application -> CPU Utilization. We are running BIG-IP 5000's and I have ASM enabled for over 200 VS's. ASM accounts for between 25-30% of cpu utilization. Total throughput on a single unit is between 350 Mb/s to 400 Mb/s currently.

NimbostratusI'm not certain I understand your question. Are you asking at what point will the load from ASM module decrease the appliance's SSL TPS offload performance? That would be a better question for F5 themselves I think, but there would likely be a overall CPU usage threshold beyond which performance would begin to decline.
