Abstract
Embodiments of a distributed virtual array data storage system and method are disclosed. Storage nodes made up of relatively unsophisticated disks with associated processors are scalable to store very large amounts of data. The storage nodes communicate with servers directly over a network through, for example, an Ethernet connection. Control of the storage nodes and access to the storage nodes is handled entirely on the server side of the system by distributed virtual array (DVA) software running on the server side and employing a particular protocol over the standard network connection. In an embodiment, server-side virtual machine (VM) hosts host application VMs that are associated with vDisks. The DVA software distributes data for the vDisk over the storage nodes. In the case of failure of one or more of the storage nodes, the DVA software reconstructs the data, for example by reading redundant data from surviving storage nodes.
