Using Encapsulation to Manage Virtual Hard Disk Data

Encapsulating the thousands of Windows operating system files into a single virtual disk file offers many benefits to an organization. As mentioned in this Tech Target report, managing a single file is substantially easier. With 10 VMs, for example, you have only 10 or so virtual disk files to manage.


The ability to encapsulate Virtual Hard Disk data has many making the jump to virtualization technologies.

"Additionally, managing a single file is substantially easier. With 10 VMs, for example, you have only 10 or so virtual disk files to manage. As a result, storing these files in a single location on your storage area network (SAN) allows multiple hosts to access them. This multiple-host configuration allows advanced technologies, such as Hyper-V's Live Migration, to function. Even without Live Migration, relocating a disk file from one host to another involves copying only one file rather than the thousands that make up an OS instance.

"Also, storing a single file is easy. A thin-provisioning configuration, for example, requires only as much storage as the file needs. Because the dollars-per-gigabyte cost of today's SANs are more expensive than traditional storage, thin provisioning on SANs and within Virtual Hard Disk files is the most efficient use of your available space."
