How is CPU/Memory shared across Virtual Servers?
Greetings, Suppose we have two websites, example1.com and example2.com, both exposed to the internet through an F5 Big-IP. Now, let’s imagine an attacker launches a DDoS attack targeting example1.com. How does the F5 allocate resources in this scenario? Does it dedicate all available resources to manage the attack, potentially making example2.com unavailable as well, or is there a mechanism to limit resource allocation—for instance, capping at 70%—to ensure the other website remains operational? This might seem like a straightforward question, but I haven’t been able to find a clear answer. Thank you!

hi ,we plan to migrate to new r-series F5 (v15.1.x) from i-series legacy appliance v13.x.x. We will create the same vlans and IP address config, but the physical interfaces will be different. The new r-series appliance is already licensed. What is the best practice for this migration? option1: import the whole UCS file to new r-series appliance. after importing the ucs to new appliance, what are the next steps to complete the whole migration? option2: copy the config for every module, for example to copy ltm config first, then gtm, final AFW ...... can someone please advise, thanks in advance!
should set hostname first on new F5 appliance before running setup utility?
