Virtual desktops simplify management, but need to be properly planned to eliminate storage performance bottlenecks, ensure performance and meet growth needs. The storage subsystem can simplify VDI deployment, but without best practices, its costs will soar. In the first part of the four articles in this series, I will help you understand the storage restrictions brought about by virtual desktops and how to overcome bottlenecks.
Over the years, it has

Step 2: Clears the remaining space of the guest OS disk, that is, writes the value 0 to every byte of the space not used by the disk. This step is critical, because in the next step, all disk space containing only 0 values will be withdrawn. You can use sdelete, a command line tool produced by sysinternals. Run the following command in the guest OS command line:

referred to as virtual desktop devices or VDI, where users install virtual desktops from the data center, which has many advantages over traditional desktop models:
1. Security enhancement

storage is designed to resemble a backup device (disk/tape). With Microsoftvirtual backup Device Interface (VDI), Windows Azure BLOB storage is encoded as a "virtual backup device," and the URL format used to access Blob storage is considered a device. The main reason for supporting Azure storage as a target device is that it provides a consistent and seamless backup and restore process, similar to our current disk and tape.
