Failover of a virtualized server
Assume that a virtualized server running five virtual machines has a hardware failure that takes the physical device down, in an active to active failover enviroment of multiple nodes do all the virtual machines failover to the same node in a cluster or could each virtual machine go to a different node? If a single machine in [...]

Active to active failover assumption
Is it assumed that in an active to active failover involving two or more nodes that there will always be a node that can receive the failover? What happens if there isn’t a node that can receive the failover because the other nodes are all maxed out? I can understand why in an active passive [...]

What is the maximum size of nodes?
The following is the definition of from Wikipedia for “high-availability cluster” High-availability clusters (also known as Failover Clusters) are implemented primarily for the purpose of improving the availability of services that the cluster provides. They operate by having redundant nodes, which are then used to provide service when system components fail. The most common size [...]
