Keepalive limitations on ACE 4710 & module

Question

I wanted to find out how many times can I apply a healthcheck in a single context. I have 50 farms that are using the same port and instead of creating 50 different healthchecks, I want to just create 1 healthcheck for the 50 farms and apply it to each farm. I also need to know if the same limitations (whatever they may be) is the same for the 4710, ACE20 and ACE30.

Answer 1

It's doncumented in the "Configuring Health Monitoring" of the configuration guide "server load balancing".
For ACE4710 running A3 :
The ACE supports  1000 unique  probe configurations, which includes ICMP, TCP, HTTP, and other  predefined health probes. The ACE can execute only up to 200 concurrent  script probes at a time. The ACE also allows the opening of 2048 sockets  simultaneously.
You can associate the same probe with multiple real servers or server  farms. Each time that you use the same probe again, the ACE counts it as  another probe instance. You can allocate a maximum of  4000 probe  instances.
