A system and method for providing storage virtualization (SV) is disclosed. According to one embodiment, a system includes a storage device having a tier 1 cache and a Tier 2 storage, an operating system and a file system having a Tier 0 memory cache that stores application data. The Tier 0 memory cache synchronizes the application data with the tier 1 cache and the Tier 2 storage.
A method and system for dynamic storage scaling based on automatically parallelizing access of names and data across multiple nodes or micro object stores (MOSs) is provided. A dynamic storage scaling device cluster is provisioned for a particular level of parallelism (e.g., N MOSs) when the cluster is created. The N MOSs may initially reside in a few physical servers (e.g., one server). When the data distribution causes peak resource usage of the physical servers, new server(s) can be added. Some micro object stores (MOSs) are moved to the new physical server(s) through a meiosis process. The storage devices associated with the moved MOSs are unmounted from the original servers and mounted to the new server(s). The meiosis continues until the cluster grows to full capacity. The scaling is dynamic and efficient since no data copy is involved in the meiosis and the initial resource cost is optimized.
