Vmware (virtual servers) - Assignment Example Question 25: The best disaster recovery for VMware is by making use of back-up process on the servers and replication of virtual machines in the network. This can be best deployed using storage where NAS is deployed for VMs and Servers in the network (Muller 123). Question 26: vMotion works by encapsulating VMs on shared storage and then the enclustered VMs allow multiple installations on an ESX server. The memory and execution state of the VMs is transferred to high speed network. This is done by copying memory and system states of the ESX server. To allow identity of the VMs, networks used by the VMs are also virtualized by the ESX server (Wolf 84). This transfer (vMotion) takes very few seconds. Question 27: A snapshot presents a complete copy of a virtual machine at any time and all the changes made. While a clone is the exact copy of the virtual machine during the cloning process. Any changes made on the parent of the clone are not reflected in the clone. Therefore using snapshots provide better functionality than clones. Question 28: Fault Tolerance in VMware works through the use of a technique known as Record/Reply. This technique provides continuous availability to the virtual machine in case the host fails. This works whereby if a VM goes down it is restarted in another host and the secondary host now becomes the primary host while a secondary host is being looked for (Muller
