Abstract

Servicing I/O operations in a cloud-based storage system, including: receiving, by the cloud-based storage system, a request to write data to the cloud-based storage system; storing, in solid-state storage of the cloud-based storage system, the data; storing, in object storage of the cloud-based storage system, the data; detecting that at least some portion of the solid-state storage of the cloud-based storage system has become unavailable; identifying data that was stored in the portion of the solid-state storage of the cloud-based storage system that has become unavailable; retrieving, from object storage of the cloud-based storage system, the data that was stored in the portion of the solid-state storage of the cloud-based storage system that has become unavailable; and storing, in solid-state storage of the cloud-based storage system, the retrieved data.

Dependent claims

A method comprising:

storing tracking metadata for at least some of multiple portions of data stored within a first tier of cloud storage, wherein the tracking metadata is stored outside of the first tier of cloud storage and the multiple portions of data correspond to multiple storage operations;
and
determining, after a data loss event among one or more storage repositories of the first tier of cloud storage and based on the tracking metadata, a consistent set of data among functioning storage repositories of the first tier of cloud storage, wherein each of the multiple storage operations corresponds to an identifier within a single time period identifier, and wherein a storage operation is committed based on storage of the tracking metadata.

Dependencies are inferred from the claim text.
