A virtual data room (VDR) is an online secure platform that allows you to share documents with multiple parties during M&A due diligence, M&A, and other financial transactions. VDRs come with a variety of features which make them more valuable for dealmakers than cloud storage tools and other document sharing apps. They also are focused on security which makes them an ideal option for business data that is sensitive as opposed to consumer cloud services that come with low security measures.
Storage virtualization is the software abstraction layer between physical storage devices and applications. It allows for more flexible and efficient use of storage resources by reducing redundancy requirements and facilitating the process of moving data and streamlining more advanced storage management features like snapshots and replication. It also helps cut expenses by removing the requirement to forecast the future storage requirements, pay for all required capacity upfront or buy and maintain multiple devices to meet the demands of growth.
Network-based storage virtualization is the most widely used type of virtualized storage. It presents a pool of storage to servers and applications over the network, for instance disks within a Fibre Channel storage area network (SAN) or Internet Small Computer System Interface storage area network (iSCSI). It uses redundant arrays of independent disks technology (RAID) to improve performance and safeguard data in the case that a single drive fails. However, the physical location of the disk and the individual hardware are kept from the applications and users.
Array-based storage virtualization is the next step, making use of an array controller to mix the storage of various arrays and display it as a single pool to applications. This lets enterprises use more cost-efficient storage tiers sharefile vs dropbox for business 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 users and servers.
