This post is a follow up to a previous post "Virtualization-Vmware-Clusters and Blade Servers" where we discussed limitations with HA in previous versions of VMware.
In vSphere 5.0 the concept of 5 primary/secondary hosts has been eliminated and the concept of master/slave exists. A single host is the master and all other hosts are slaves, if the master fails then an election process is kicked off and a new master is elected.
This eliminates issues in previous versions of VMware where the primary/secondary concept existed and we needed to consider
- Number of hosts in a cluster
- Managing the role of the host
- Number of consecutive host failures
- Placement of hosts across blade chassis and stretched clusters
- Partition scenarios likely to occur in stretched cluster environment
By the way Dave thanks for the link
