Question

An administrator is performing a migration of a physical cluster that uses boot from SAN into private cloud. The systems administrator needs to minimize the downtime required. Which of the following migrations is the BEST option for the systems administrator to use?

Options

  • AP2V with cold system cloning on the storage infrastructure.
  • BP2V with storage migration on the hypervisor.
  • CP2V with copy of the LUNs into data stores for hypervisor access.
  • DP2V with raw device mapping/pass-through LUNs on the storage system.

Why each option

The best P2V migration option for a boot-from-SAN physical cluster with minimal downtime involves copying LUNs directly to hypervisor datastores. This method virtualizes storage, providing flexibility and efficient integration into the private cloud.

AP2V with cold system cloning on the storage infrastructure.

P2V with cold system cloning requires the physical system to be offline for an extended period during the cloning process, which directly contradicts the requirement to minimize downtime.

BP2V with storage migration on the hypervisor.

P2V with storage migration on the hypervisor implies the virtual machine already exists; the question is about the initial P2V migration of a physical system, not migrating storage for an existing VM.

CP2V with copy of the LUNs into data stores for hypervisor access.Correct

To minimize downtime for a boot-from-SAN physical cluster P2V migration, copying the LUNs directly into datastores accessible by the hypervisor is the most effective method. This allows the hypervisor to manage the storage virtualized, providing flexibility and leveraging existing storage capabilities without requiring complex pass-through configurations or cold cloning which increases downtime. The process typically involves presenting the SAN LUNs to a P2V conversion tool or directly to the hypervisor, converting them to virtual disk formats (e.g., VMDK, VHDX), and placing them into the hypervisor's datastores.

DP2V with raw device mapping/pass-through LUNs on the storage system.

P2V with raw device mapping/pass-through LUNs on the storage system allows the VM to directly access physical LUNs but complicates storage management, snapshotting, and mobility within the virtual environment, and doesn't inherently minimize the initial conversion downtime compared to copying to a virtual disk format.
