Explain the concept of "storage vMotion" in virtualization and its role in data storage management

Describe storage virtualization and its benefits for managing storage resources in data centers.

Data stored in memory may be retrieved in one of two ways: sequentially or directly. What are the advantages of direct access and why do modern key devices use it? How can data written to a device that only supports sequential access be converted so that it can be read by a device that only supports the direct access method?

Provide an overview of the concept of virtualization in storage systems, including software-defined storage and virtual SANs.

What are the key considerations when deciding between "thin provisioning" and "thick provisioning" in virtual storage management?

How does storage architecture vary from file architecture? Is there more than one method to explain this dissimilarity?
