Which of the following technologies provides an abstraction of physical drives within a storage array?

Fabric virtualization refers to the abstraction of the network connecting servers and storage (e.g., Fibre Channel fabric), not the physical drives themselves.

Disk virtualization, often implemented within a storage array's controller, pools physical hard drives and presents them as logical disk units (LUNs) to servers. This abstraction hides the complexity of the underlying physical storage, allowing for features like RAID, thin provisioning, and easy capacity expansion without directly managing individual drives.

SAN virtualization (Storage Area Network virtualization) typically refers to the aggregation and management of multiple storage arrays or the virtualization of the SAN infrastructure, which is a broader scope than just the physical drives within a single array.

Server virtualization abstracts physical servers, allowing multiple virtual machines to run on a single physical host, and is unrelated to the abstraction of physical drives within a storage array.
