What Are Virtual Data Rooms and Storage Virtualization?
A virtual dataroom (VDR) allows you to securely share documents online with multiple parties in M&A due-diligence as well as other financial transactions. VDRs come with a variety of features that make them more beneficial to dealmakers than cloud storage apps and other document sharing tools. They also place a premium on security, which makes them better for business data that is sensitive than cloud-based services for consumers that are not secure.
Storage virtualization is an abstraction layer that is positioned between physical storage devices, and applications. It enables more flexible and efficient use of storage resources by reducing hardware redundancy requirements, making it easier to manage data migrations and streamlining complex storage management features like snapshots and replication. It can also lower costs by eliminating the need to forecast the future storage requirements and to pay for all the necessary capacity upfront, or purchase and maintain multiple devices to accommodate expansion.
Network-based storage virtualization is the most popular form of virtualized storage. It takes a pool storage, such as disks in a Fibre Channel (FC) or Internet Small Computer System Interface (iSCSI) storage area network (SAN) and then exposes it to servers and other applications over the network. It makes use of redundant arrays independent disks technology (RAID) to improve performance and safeguard data in the case that one drive fails. However, the physical location of the disk as well as the individual hardware are hidden from users and applications.
Storage virtualization with arrays is the next step. A storage controller can be utilized to integrate storage from multiple arrays into one pool and present it to applications. This lets enterprises use more cost-efficient storage tiers that might include solid-state drives or hard disk drives of varying capacities, and conceal the physical location of these different kinds of storage from servers and users.
