US Patent 10148751 Asymmetric active-active storage for hyper-converged system

A technique for providing active-active access to data over distance includes designating a first geographical site as a preferred site and designating a second geographical site as a non-preferred site. In response to a computing node at either site encountering a write request to write data to a storage object shared across both sites, the write request is handled by the preferred site, where the specified data is written to local storage at the preferred site and mirrored to local storage at the non-preferred site.
