Storage virtualization is a way to combine physical storage devices into what appears to be one data pool. This is achieved by aggregating the storage capacity of various devices and present them to the server as one entity, thereby removing redundant hardware and improving the efficiency of storage.
A VDR (virtual data room) can be used to streamline the process of due diligence or to raise funds from investors by allowing several parties to collaborate in a safe and secure environment. VDRs also provide a broad array of tools that can simplify project management and ease collaboration. However they can be costly and lack some advanced features available in cloud storage solutions.
Cloud storage services allow users to store and retrieve data remotely from browsers, which eliminates the need for expensive hardware redundancies. However, they do require confidence that your company’s data is protected by a third-party.
Block storage virtualization, which is a software program, creates a barrier that separates the physical disk drives from the operating system. This allows the drives to be accessed more quickly than if the data was directly read from the drive. It also eliminates the need for an additional hardware platform such as RAID to manage storage devices and simplifies the storage architecture.
File virtualization concentrates on NAS storage architecture. This enables enterprises to optimize their storage usage by consolidating servers, as well as perform non-disruptive file migrations. It does this by eliminating the dependency on the physical directories and file systems and delivering advanced functionality like caching, tiering, and replication at the storage virtualization layer.
