A virtual dataroom (VDR) lets you 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 tools and other document sharing applications. They also concentrate on security, making VDRs a better option for business data that is sensitive than consumer cloud services that have low security measures.
Storage virtualization is the software abstraction layer between physical storage devices and applications. It enables the more efficient and flexible use of storage resources by reducing redundancy requirements, easing data migrations and streamlining advanced storage management functions like snapshots and replication. It also reduces costs by removing the need to anticipate long-term storage needs and pay for all necessary 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 Fibre Channel (FC) or Internet Small Computer System Interface (iSCSI) storage area network (SAN), and presents it to applications and servers over the network. It makes use of redundant arrays independent disks technology (RAID) to enhance performance and protect data in the event that a single drive fails. However, the physical location of the disk and the individual hardware are kept from the users and applications.
Array-based storage virtualization is the next step, using the storage controller to blend the storage of various http://www.virtualdataspace.biz/what-is-a-bolt-on-acquisition/ arrays and display it as a single pool to applications. This allows enterprises to use more cost-efficient storage tiers that may include solid-state drives and hard disk drives of various capacities, and hide the physical location of these different types of storage from the servers and users.
