A virtual dataroom (VDR) lets you securely share online documents with several parties in M&A due-diligence, M&A, and other financial transactions. VDRs come with a variety of features which make them more valuable to dealmakers than cloud storage applications and other document sharing tools. They also are focused on security, which makes them the best option for sensitive business data as opposed to consumer cloud services that come with limited security measures.
Storage virtualization is a software abstraction layer that is positioned between physical storage devices and applications. It allows for a more efficient and flexible storage resource utilization by cutting down on the need for redundant hardware, easing data transfers, and streamlining complex management functions like snapshots and replicas. It can also lower costs by removing the need to anticipate the storage requirements for the long term and to pay for all the necessary capacity in advance, or to purchase and maintain multiple devices to support growth.
The most commonly used virtualized storage is network-based virtualization. It is a way to take a pool of storage, such as 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 utilizes redundant arrays of independent disks technology (RAID) to improve performance and safeguard data in the event that one drive fails. However, the physical location of the disk and the individual hardware are kept from the application and users.
Array-based storage virtualization goes to the next step, utilizing a storage controller to combine storage from different arrays and display it as a single pool to applications. This allows enterprises to use more cost-effective storage tiers that may include solid-state drives and hard disk drives of various capacities, and conceal the physical location of these different kinds of storage from servers and users.
