I have some topics to be discussed regarding HA. Basically I have below questions about HA
1). How does HA works in mixed ESxi cluster environment, Say I have 4.1 ESxi and 5.0 ESxi clustered together. As 4.1 uses AAM and 5.1 uses FDM , which agent will be used in this cluster? Does Master/Slave method or Primary/Slave method is used?
2).What has changed with 5.1 and what has not changed with 5.1 with regards to HA in VMWare when compared with 4.1.
1) In your Scenario the FDM will apply . All the Hosts will be upgraded with the latest HA Agents.
2) The host agent is only changed in 5.1 and all the other below hosts nothing else will be imapcted.
These 2 blog are must to read for you in order to clear your doubt:
Thanks for the replay.
I am just curious, what has changed in 5.1 HA when compared with 4.1 HA. Does the working remains the same? its only the agent which got changed?
