What Are Virtual Data Rooms and Storage Virtualization?

A virtual dataroom (VDR) lets you securely share online documents with many parties in M&A, due-diligence and other financial transactions. VDRs offer a variety of features which can make them more valuable to dealmakers than cloud storage tools and other document sharing applications. They also concentrate on security which makes them more suitable for sensitive business data than consumer cloud services with minimal security measures.

Storage virtualization is the software abstraction layer that connects physical storage devices and applications. It enables more efficient and flexible use of storage resources by reducing redundancy requirements, making it easier to manage the process of moving data and streamlining more advanced storage management functions, such as snapshots and replication. It can also cut costs by eliminating the requirement to forecast the future needs for storage and pay for all the required capacity up front or purchase and manage multiple devices to keep pace with the growth.

Network-based storage virtualization http://virtualdataspace.biz/box-vdr-main-features is the most well-known form of virtualized storage. It provides a pool of storage to applications and servers via the network, like disks within the Fibre Channel storage area network (SAN) or Internet Small Computer System Interface storage area network (iSCSI). It usually uses redundant array of independent disks (RAID) technology to improve performance and safeguard data in the event that one disk fails, but the specific physical location of the disk as well as the specific hardware used are hidden from users and applications.

Storage virtualization using arrays is the next step. A storage controller is employed to combine the storage of multiple arrays into a single pool and then present it to applications. This allows enterprises to use storage tiers at lower costs that could include hard disk drives and solid-state drives with various capacities. They can also hide the physical storage location from servers and users.
