Co-located journaling and data storage for write requests

A distributed storage system comprising:

• physical storage, including a plurality of physical storage devices provided by a cloud computing environment, wherein the plurality of physical storage devices are associated with respective logical storage units of a plurality of logical storage units;
• one or more processors;
• and
• a non-transitory computer-readable storage medium embodying instructions, which when executed by the one or more processors, cause the distributed storage system to:
• for each logical storage unit of the plurality of logical storage units, co-locate journaling and data storage by maintaining, within the logical storage unit, a journal partition and a volume partition, wherein the volume partition represents a volume contained within the logical storage unit or to which the logical storage unit corresponds;
• and
• distribute journaling of metadata associated with a plurality of incoming write requests received from one or more clients of the distributed storage system among the plurality of logical storage units by, for each write request of the plurality of incoming write requests:
• identifying a destination logical storage unit to which data associated with the write request is to be stored;
• and
• causing the data and metadata associated with the write request to be persisted to the physical storage by journaling the metadata and the data to respective portions of an active log within the journal partition of the destination logical storage unit.

A non-transitory computer-readable storage medium embodying instructions, which when executed by one or more processors of a cluster of virtual platforms collectively representing a distributed storage system, cause the distributed storage system to:

• for each logical storage unit of a plurality of logical storage units of the distributed storage system, co-locate journaling and data storage by maintaining, within the logical storage unit, a journal partition and a volume partition, wherein the volume partition represents a volume contained within the logical storage unit or to which the logical storage unit corresponds;
• and
• distribute journaling of metadata associated with a plurality of incoming write requests received from one or more clients of the distributed storage system among the plurality of logical storage units by, for each write request of the plurality of incoming write requests:
• identifying a destination logical storage unit to which data associated with the write request is to be stored;
• and
• causing the data and metadata associated with the write request to be persisted to physical storage by journaling the metadata and the data to respective portions of an active log within the journal partition of the destination logical storage unit.
