Abstract: Systems and methods are disclosed for reducing interdependency among control plane on a block storage system. Embodiments described herein can implement a key-value data store on the data plane servers. In one embodiment, the key-value store stores data regarding placement constraints and enables the block storage system to make placement decisions without control plane dependencies. In another embodiment, the key-value store persisted by the data plane enable the block storage system to migrate volumes while maintaining performance settings.
