Great, right? HA kicked in? That\u2019s good \u2026 right!?!?!<\/p>\n
Ummm maybe not. Let me ask you a question. Which is worse:<\/p>\n
For most people, option A is more favourable and this is why Microsoft is giving us Cluster Compute Resiliency.<\/p>\n
With this new feature, a cluster will become more tolerant (and this is configurable) to transient network errors. In the event of a heartbeat timeout, the host will go into isolation. This will allow VMs on that host to continue executing and prevent additional VMs being placed onto that host. If the host becomes responsive within a certain time frame then it comes out of isolation. If the host does not become responsive then VMs are failed over to other hosts.<\/p>\n
Note that if a host is determined to be \u201cflapping\u201d then it will be put into Cluster Quarantine.<\/p>\n","protected":false},"excerpt":{"rendered":"
