A virtual dataroom (VDR) allows you to securely share online documents with multiple parties in M&A due-diligence, M&A, and other financial transactions. VDRs provide a range 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 confidential business information than cloud-based services for consumers with minimal security measures.

Storage virtualization is the software abstraction layer that connects physical storage devices and applications. It allows for a more efficient and flexible storage resource utilization by decreasing the requirement for hardware redundancy, simplifying data migrations, and streamlining advanced management functions like replicas and snapshots. It also reduces costs by removing the requirement to forecast the future storage requirements and to purchase all needed capacity upfront, or purchase and maintain multiple devices to accommodate growth.

The most widely used type of virtualized storage is network-based virtualization. It uses a pool of storage, like disks in a http://virtualdataspace.biz/for-progressive-approach-use-board-room-software Fibre Channel (FC) or Internet Small Computer System Interface (iSCSI) storage area network (SAN) and exposes it to servers and applications over the network. It uses redundant arrays of independent disks technology (RAID) to enhance performance and protect data in the event that one drive fails. However, the physical location of the disk as well as the individual hardware are hidden from users and applications.

Array-based storage virtualization goes to the next step, utilizing storage controllers to combine the storage of various arrays and display it as a single pool for applications. This allows companies to utilize storage tiers at lower costs and may include hard disk drives and solid-state drives with different capacities. They can also hide the physical storage location from servers and users.
