Design help for high TPS application
Feel free to point me to posts that answer my question if this is somewhat redundant. We are deploying a 2000+ TPS (transactions/second) applicaiton that is loadbalanced by a pair of BIG-IPs. We have to maintain some level of persistence, keeing sessions pinned for 10 minutes, so on the virtual, "persist hash" has been used.
A monitor exists to check for a status HTTP page on each system.
monitor someapp {
defaults from http
recv "someapp"
send "GET / HTTP/1.1\nHost:x.x.x.x\n etc.etc.\n\n"
}
The problem comes that if a member of the pool that has sessions pinned to it goes down, the time that it takes to mark the member offline can result in 500 or more failed transactions. Any design ideas or helps would be appreciated.
Thanks,
Keith
