Abstract
Techniques for recovery and redistribution of data from a virtual disk storage system are described herein. In one or more implementations, a storage scheme derived for a virtual disk configuration is configured to implement various recovery and redistribution designed to improve recovery performance. The storage scheme implements one or more allocation techniques to produce substantially uniform or nearly uniform distributions of data across physical storage devices associated with a virtual disk. The allocation facilitates concurrent regeneration and rebalancing operations for recovery of data in the event of failures. Additionally, the storage scheme is configured to implements parallelization techniques to perform the concurrent operations including but not limited to controlling multiple parallel read/writes during recovery.
