N-way parity for virtual disk resiliency

One or more computer-readable storage media storing instructions that, when executed by one or more components of a computing device, implement a storage system configured to perform operations including:

• ascertaining a designated number of units of redundancy data to store with client data on a virtual disk, the designated number being determined during configuration of the virtual disk from a range of options for resiliency made available for user customization of the virtual disk configuration, the range of options constrained by a lower bound placed upon values for the designated number of units of redundancy data that varies based on a number of physical storage devices for the storage system;
• configuring a storage scheme for the virtual disk in accordance with the selected number of units of redundancy data;
• obtaining client data for storage on the virtual disk;
• generating redundancy data for the client data to include the designated number of units of redundancy data;
• and
• storing the client data and the redundancy data across multiple physical storage devices of the virtual disk in accordance with the storage scheme.

A computing system comprising:

• one or more processing components;
• one or more computer-readable storage media storing instructions that, when executed by the one or more processing components, implement a disk manager module configured to perform operations including:
• ascertaining a designated number of units of redundancy data to store with client data on a virtual disk, the designated number being determined during configuration of the virtual disk based on a selection from a range of options for resiliency exposed in a configuration user interface for user customization of the virtual disk configuration, the range of options configured as a reduced set of options that excludes one or more possible options for the virtual disk configuration;
• configuring a storage scheme for the virtual disk in accordance with the selected number of units of redundancy data;
• obtaining client data for storage on the virtual disk;
• generating redundancy data for the client data to include the designated number of units of redundancy data;
• and
• storing the client data and the redundancy data across multiple physical storage devices of the virtual disk in accordance with the storage scheme.
