Question

What are the improvements available to VHDX?

Answer 1

- Because disk sizes may increase dramatically, a VHDX supports 64 TB, whereas the older VHD supports only 2 TB. - The disk structure is improved to reduce the chances of problems when a host server suffers a power outage. - The VHDX features much better storage alignment when used with large sector sizes. - The VHDX allows a larger block size for dynamically expanding and differencing disks, which provides better performance for these workloads.

Answer 2

Step 1. In Server Manager, select Tools > Hyper-V Manager. Step 2. In the Actions pane, click New > Hard Disk. Step 3. On the Before You Begin page of the New Virtual Hard Disk Wizard, click Next. Step 4. On the Choose Disk Format page, select VHD or VHDX or VHD Set and then click Next Step 5. On the Choose Disk Type page, choose Fixed size and then click Next. Step 6. On the Specify Name and Location page, enter a name for the virtual hard disk, specify a folder to host the virtual hard disk file, and click Next. Step 7. On the Configure Disk page, select one of the following options: Create a new blank virtual hard disk of the specified size: Select this option for a new disk of any size and any purpose. Of course, the disk is empty of contents. Copy the contents of a specified physical disk: Select this option to replicate an existing physical disk on the server as a virtual hard disk. The fixed-size hard disk will be the same size as the disk that you have replicated. Replicating an existing physical hard disk does not alter data on the existing disk. Copy the contents of a specified virtual hard disk: Select this option to create a new fixed-size hard disk based on the contents of an existing virtual hard disk.

Answer 3

New-VHD and -Fixed

Answer 4

Step 1. Ensure that the target hard disk is offline. Step 2. Use the Hyper-V Manager to edit the existing virtual machine’s properties. Step 3: Click an IDE or SCSI controller, click Add, and then click Hard Drive Step 4. In the Hard Drive dialog box, select Physical Hard Disk. In the drop- down list box, select the disk that you want to use as the pass-through disk.

Answer 5

- You can link multiple differencing disks to a single parent disk. - When you modify a parent disk, all linked differencing disks fail. - You can reconnect a differencing disk to the parent by using the Inspect Disk tool; this tool is available in the Actions pane of the Hyper-V Manager. - You can use the Inspect Disk tool to locate a differencing disk’s parent disk.

Answer 6

This is a “point in time” image of the virtual machine. A production checkpoint can be restored later in a way that is supported by all workloads. A production checkpoint uses a backup technology inside the guest VM to create the checkpoint; note that this is an alternative to saved state technology.

Answer 7

This is a checkpoint that captures the state, data, and hardware configuration of a running virtual machine. Standard checkpoints are intended for use in development and testing scenarios; for example, you might use a standard checkpoint to re-create a specific state of a virtual machine so that you can further troubleshoot a scenario.

Answer 8

- It permits fairness improvements between VMs using the same file cluster. - It allows policy-based minimum and maximum performance goals to be configured in units of normalized IOPs. - It prevents single virtual machines from consuming all storage resources. - You can view performance details of all running virtual machines and the configuration of the Scale-Out File Server cluster from a single location. - It provides consistent performance to virtual machines, even in dense and overprovisioned environments.
