System and method for data storage in distributed system across multiple fault domains

A method for storing data in a data storage system, comprising:

• obtaining, by an accelerator pool comprising memory and persistent storage, a data storage request for first data;
• storing a copy of the first data locally in the memory;
• in response to storing the copy of the first data and prior to the first data being stored in more than one fault domain and prior to any copies of the first data being stored in the persistent storage:
• sending an acknowledgement to a requesting entity that generated the data storage request;
• and
• after sending the acknowledgement, storing at least one second copy of the first data in data silos,
• wherein the acknowledgement indicates that the first data is redundantly stored in at least two different fault domains.

A non-transitory computer readable medium comprising computer readable program code, which when executed by a computer processor enables the computer processor to perform a method for storing data in a data storage system, the method comprising:

• obtaining, by an accelerator pool comprising memory and persistent storage, a data storage request for first data;
• storing a copy of the first data locally in the memory;
• in response to storing the copy of the first data and prior to the first data being stored in more than one fault domain and prior to any copies of the first data being stored in the persistent storage:
• sending an acknowledgement to a requesting entity that generated the data storage request;
• and
• after sending the acknowledgement, storing at least one second copy of the first data in data silos,
• wherein the acknowledgement indicates that the first data is redundantly stored in at least two different fault domains.
