What Are Virtual Data Rooms and Storage Virtualization?



A virtual dataroom (VDR) allows you to securely share documents online with many parties in M&A due-diligence as well as other financial transactions. VDRs provide a range of features that make them more beneficial to dealmakers than cloud storage tools and other document sharing applications. They also are focused on security, which makes VDRs a better option for sensitive business data as opposed to consumer cloud services that come with limited security measures.

Storage virtualization is the layer of abstraction software between physical storage devices and applications. It allows for the more efficient and flexible use of storage resources by reducing redundancy requirements, easing data migrations and streamlining complex storage management functions such as snapshots and replication. It can also cut expenses by removing the need to forecast the future needs for storage, pay for all needed capacity up front or purchase and manage multiple appliances in order to meet the demands of growth.

The most common storage that is virtualized is the network-based virtualization. It uses a pool of storage, like disks in a Fibre Channel (FC) or Internet Small Computer System Interface (iSCSI) storage area network (SAN) and then presents it to servers and applications over the network. It uses redundant arrays of independent disks technology (RAID) to improve performance and safeguard data in the case that one drive fails. However, the exact physical location of the disk as well as the hardware that it is attached to are hidden from the applications and users.

Array-based storage virtualization is the next step, using a storage controller to combine storage from different arrays and display it as a single pool to applications. This allows businesses to use storage tiers that cost less, which may include hard disk drives and solid-state drives with various capacities. They can also hide the physical location from users and servers.
