SSO in HA mode with LB

Hi All,

I read about SSO in HA mode and realized that we need to have load balancer in place. This is needed when SSO A goes down then it can switch over the requests to SSO B.

For this to happen we need to point the SSO components like Admin server - STS and others to this Load balancer -- the Virtual IP.

What if -- if the Load Balancer goes down then will someone be able to login to the Virtual Infra.

Please correct if I am wrong

Thanks
