SwiftStack sucks up $6.1m, leaps through curtains with 'Amazon S3-in-a-box'
Software-defined storage upstart Swiftstack has been given a fresh cash injection of $6.1m and has spoken out on its software-as-a-service offering, Swift. Software defined storage (SDN) is akin to the fabless semiconductor firm concept, except that in this case the firms provide software instead of chip designs. With software defined storage, you buy storage controller software to run in a server as an app, or as an app in a virtual machine, and give it some commodity disk drive or flash capacity. The storage software then presents it as block, file, or some other flavour of unified storage. Crucially, the control rests with the software rather than the underlying storage hardware.
