- Failure to set up a full tunnel mesh for VM in a tier shall result in VM deployment failure.
- Failure to setup one or more bridge of the VPC, in full-connected mesh topology shall result in logical router to be disabled
Convergence time
Following are the events that require state update of configuration and corresponding latency:
- Latency to replicate configuration is proportional to (n*(n-1))/2 * m where n is the number of hosts on which VPC spans and m is the number of tiers in the VPC. n*(n-1)/2
Architecture & Design description
...
- list of hosts on which VPC spans
- state(enabled/disabled) of logical router on a host for the VPC
- state of tunnels between the hosts for a tier in the VPC
Convergence time
Following are the events that require state update of configuration and corresponding latency:
- on first VM launch/ last VM destroy on a host need setting up/destroy tunnel mesh for each tier's bridge with rest of the hosts. Latency to replicate configuration is proportional to (n*(n-1))/2 * m where n is the number of hosts on which VPC spans and m is the number of tiers in the VPC. n*(n-1)/2
