Abstract
Resiliency techniques for a virtual disk are described that enable user control over storage efficiency and recovery time. Configuration parameters for a virtual disk are obtained that indicate a number of available storage devices and a specified tolerance for storage device failures. A default configuration for the virtual disk that designates a default amount of redundancy data to store with client data to balance storage efficiency and recovery time is derived based on the configuration parameters. Options may then be provided to specify a custom configuration that changes the amount of redundancy data to customize the level of storage efficiency and recovery time. The virtual disk is configured and data is stored thereon in accordance with the default configuration or the custom configuration as directed by the user.
