What would be the advantage of having two servers with external iscsi stroage running vmware vsphere essentials as opposed to two servers with their own on board storage? iscsi storage is more complex and expensive than just purchasing the two servers with on board storage. So is external storage really necessary? What do I lose? If a server goes down, I'll be able to load the VM to the other server from backup quickly, correct?
Even though essentials doesn't include vmotion and HA, going virtual will still help reduce downtime, increase availability and performance, correct? If so How?
