US 2025/0060911 A1 · Scalable Solid-State Storage System and Methods Thereof

Abstract

Methods and systems for solid state drives are provided, including assigning a first namespace to a first instance of a storage operating system and a second instance of the storage operating system for enabling read access to a first portion of a flash storage system by the first instance, and read and write access to the second instance; allocating a second namespace to the first instance for exclusive read and write access within a second portion of the flash storage system; generating, by the first instance, a request for the second instance to transfer a data object from the second portion owned by the first instance to the first portion; storing, by the second instance, the data object at the first portion; and updating metadata of the data object at the second portion, the metadata indicating a storage location at the second portion where the data object is stored.

Dependent claims

A method executed by one or more processors, comprising:

assigning a first shared namespace to a first instance and a second instance of a storage operating system for enabling write access to the first instance to a first zone of a first portion of a flash storage system, and write access to the second instance to a second zone of the first portion;
utilizing a first exclusive namespace by the first instance to store metadata at a first segment of a second portion of the flash storage system;
utilizing a second exclusive namespace by the second instance to store metadata at a second segment of the second portion of the flash storage system;
and
providing read only access to the first instance and the second instance to a third zone of the first portion using the first shared namespace.

A non-transitory, machine-readable storage medium having stored thereon instructions comprising machine executable code, which when executed by a machine, causes the machine to:

assign a first shared namespace to a first instance and a second instance of a storage operating system for enabling write access to the first instance to a first zone of a first portion of a flash storage system, and write access to the second instance to a second zone of the first portion;
utilize a first exclusive namespace by the first instance to store metadata at a first segment of a second portion of the flash storage system;
utilize a second exclusive namespace by the second instance to store metadata at a second segment of the second portion of the flash storage system;
and
provide read only access to the first instance and the second instance to a third zone of the first portion using the first shared namespace.

2 more elements

A system, comprising:

a memory containing machine readable medium comprising machine executable code having stored thereon instructions;
and a processor coupled to the memory to execute the machine executable code to:
assign a first shared namespace to a first instance and a second instance of a storage operating system for enabling write access to the first instance to a first zone of a first portion of a flash storage system, and write access to the second instance to a second zone of the first portion;
utilize a first exclusive namespace by the first instance to store metadata at a first segment of a second portion of the flash storage system;
utilize a second exclusive namespace by the second instance to store metadata at a second segment of the second portion of the flash storage system;
and
provide read only access to the first instance and the second instance to a third zone of the first portion using the first shared namespace.
