A virtual dataroom (VDR) allows you to securely share online documents with multiple parties in M&A due-diligence, due diligence and other financial transactions. VDRs are a wealth of features which make them more valuable to dealmakers than cloud storage applications and other document sharing tools. They also emphasize security, which makes them better for sensitive business data than cloud-based services for consumers that have minimal security measures.
Storage virtualization is a kind of software abstraction layer that connects physical storage devices, and applications. It allows for a more efficient and flexible storage resource by cutting down on the requirement for hardware redundancy, simplifying data transfer, and streamlining advanced management functions like replicas and snapshots. It also reduces costs by removing the requirement to plan long-term storage needs and to purchase all needed capacity in advance, or to purchase and maintain multiple appliances to support expansion.
The most popular type of virtualized storage system is network-based virtualization. It takes a pool of storage, like disks in a Fibre Channel (FC) or Internet Small Computer System Interface (iSCSI) storage area network (SAN), and presents it to servers and applications over the network. It uses redundant arrays of independent disks technology (RAID) to http://www.virtualdataspace.biz/dropbox-vs-sharefile-what-to-choose/ enhance performance and protect data in the event that a single drive fails. However, the exact physical location of the disk as well as the individual hardware are hidden from users and applications.
Storage virtualization using arrays is the next step. A storage controller can be employed to combine the storage of multiple arrays into a single pool and then present it to applications. This allows enterprises to use more cost-effective storage options that may include solid-state drives and hard disk drives of various capacities, and conceal the physical location of these various types of storage from both servers and users.
