Storage virtualization integrates physical storage devices into what appears to be one data pool. This is accomplished by aggregating the storage capacity of various devices and connecting them to the server as a single entity, thereby removing redundant hardware and boosting the efficiency of storage.
A VDR (virtual data room) can be used to simplify due diligence processes or fundraising from investors by allowing different parties to work in a secure setting. VDRs provide a range of tools that help simplify project management and allow for collaboration. However they can be costly and lack some advanced features that are available in cloud storage solutions.
Cloud storage services permit users to store and retrieve data remotely using browsers, which eliminates the need for costly hardware redundancies. It does, however, require a confidence that your company’s data is kept safe by a third party.
Block storage virtualization is a program that creates a barrier between the physical disk drives and the operating system, which allows them to be read faster than being read directly from the drive. It also eliminates a separate hardware platform, like RAID that manages storage devices.
File virtualization is primarily focused on NAS storage architecture. This enables enterprises to optimize their storage use, consolidate servers, and conduct non-disruptive transfers of files. It does this by removing the dependency on the physical directories and file systems, and providing advanced features such as tiering, caching and replication at the storage virtualization layer.
