1-3-4 Storage Virtualization Explained

Key Concepts

Storage Virtualization

Storage Virtualization is the process of abstracting physical storage devices into a logical entity. This allows for easier management, scalability, and utilization of storage resources. By virtualizing storage, administrators can treat multiple physical storage devices as a single, unified storage pool. Think of it as combining multiple bookshelves into one large library, making it easier to find and manage books.

Virtual Storage Area Networks (VSANs)

VSANs are virtualized storage networks that consolidate physical storage resources into a single logical storage unit. VSANs enable efficient data sharing and management across different physical storage devices. They are particularly useful in data centers where multiple servers need access to shared storage. Imagine VSANs as a virtual bridge that connects different storage islands into a single, accessible network.

Storage Resource Pools

Storage Resource Pools are collections of physical storage devices that are grouped together and managed as a single entity. These pools can be dynamically allocated to different applications and users based on demand. Storage Resource Pools provide flexibility and efficiency by allowing storage to be allocated and reallocated as needed. Think of it as a flexible storage container that can be resized and reshaped to fit different storage needs.

Data Deduplication

Data Deduplication is a technique used to eliminate duplicate copies of repeating data. This reduces storage overhead and improves storage efficiency. Deduplication is particularly useful in environments with large amounts of redundant data, such as backups and archives. Imagine data deduplication as a process that removes duplicate pages from a book, reducing the overall size while retaining all the necessary information.
