Abstract
One or more techniques and/or systems are provided for configuring a storage environment. In particular, the storage environment may be configured with a symmetric frontend and an asymmetric backend. That is, an owner storage controller may be granted read/write access to a storage device owned by the owner storage controller, while a non-owner storage controller may be granted merely read access. In this way, the owner storage controller may execute, log, and/or commit a write command to the storage device, while the non-owner storage controller may merely execute, but not log and/or commit, a write command. Write buffers, log memories, and/or file system metadata may be synchronized between the owner storage controller and the non-owner storage controller, such that the non-owner storage controller may efficiently take ownership of the storage device in response to a failure of the owner storage controller.
