Implementing a heterogeneous storage tiering regime for high-performance failure recovery

A method for using network accessible volumes in failure recovery operations, the method comprising:

• configuring a computing cluster having at least two nodes, the at least two nodes hosting virtualized entities that are configured to access a common storage access address space, and the at least two nodes having respective one or more node-local non-volatile storage devices, wherein the respective one or more node-local non-volatile storage devices are configured into a first storage tier that stores node-local data;
• attaching additional cloud-provided storage to the at least two nodes having their respective one or more node-local non-volatile storage devices, wherein the additional cloud-provided storage is configured into a second storage tier that stores one or more replicas of the node-local data;
• responding to a node failure event by:
• attaching the additional cloud-provided storage to a replacement node;
• and
• rebuilding, on the replacement node, rebuilt first storage tier data based on the one or more replicas of the node-local data that are stored in the second storage tier of the additional cloud-provided storage.

A system for using network accessible volumes in failure recovery operations, the system comprising:

• a storage medium having stored thereon a sequence of instructions;
• and
• a processor that executes the sequence of instructions to cause the processor to perform acts comprising,
• configuring a computing cluster having at least two nodes, the at least two nodes hosting virtualized entities that are configured to access a common storage access address space, and the at least two nodes having respective one or more node-local non-volatile storage devices, wherein the respective one or more node-local non-volatile storage devices are configured into a first storage tier that stores node-local data;
• attaching additional cloud-provided storage to the at least two nodes having their respective one or more node-local non-volatile storage devices, wherein the additional cloud-provided storage is configured into a second storage tier that stores one or more replicas of the node-local data;
• responding to a node failure event by:
• attaching the additional cloud-provided storage to a replacement node;
• and
• rebuilding, on the replacement node, rebuilt first storage tier data based on the one or more replicas of the node-local data that are stored in the second storage tier of the additional cloud-provided storage.
