Question 1

Virtual Hard Disk (VHD) Architecture explained

Answer 1

A virtual hard disk (VHD) is a file that encapsulates a hard disk image. VHDs can be used in new and interesting ways. VHDs first were created to be the storage media for virtual machines (VMs). Today, VHDs are used to ship trial versions of software, used in backup solutions, used for bug triage (e.g. customers can convert a physical disk to virtual and share it), and even used to store multiple boot environments. VHDs are a very flexible storage container and are not tied to any single file system format. Since June 2005, Microsoft has made the VHD Image Format Specification available to third parties under the Microsoft Open Specification Promise (OSP).

Question 2

New-StorageSubsystemVirtualDisk

Answer 2

Allows the creation of a VirtualDisk object on a storage subsystem that does not support creation of storage pools.

Question 3

Private swith

Answer 3

Private

Private virtual networks are used where you want to allow communications between

Virtual machine to virtual machine on the same physical server
In a block diagram, a private network is an internal network without a virtual NIC in the parent partition. A private network would commonly be used where you need complete isolation of virtual machines from external and parent partition traffic. DMZ workloads running on a leg of a tri-homed firewall, or an isolated test domain are examples where this type of network may be useful.

Question 4

External swith

Answer 4

External

External virtual networks are used where you want to allow communications between

Virtual machine to virtual machine on the same physical server

Virtual machine to parent partition (and visa-versa)
Virtual machine to externally located servers (and visa-versa)
(Optional) Parent partition to externally located servers (and visa-versa)

Question 5

Internal swith

Answer 5

internal

Internal virtual networks are used where you want to allow communications between
Virtual machine to virtual machine on the same physical server
Virtual machine to parent partition (and visa-versa)
In a block diagram, an internal network is an external network without the binding to a physical NIC. An internal network would commonly be used to build a test environment where you need network connectivity into the virtual machines from the parent partition itself.
