Abstract

A GUID partition table (GPT) based Hidden Data Store (HDS) system includes first computing systems that include networked storage devices and that are coupled to a second computing system through a network. The second computing system include local storage devices that provide a GPT having a GPT entry that identifies local HDS elements that provides an HDS and that are included on the local storage devices, and networked HDS elements that provide the HDS and that are included on the networked storage devices. The second computing system also includes an HDS engine that receives the GPT entry and authorization credentials, determines that the authorization credentials allow access to the HDS and, in response, provides access to the local HDS elements that are included on the local storage devices, and provide access to the networked HDS elements that are included on the networked storage devices.

5. The GPT based HDS system of claim 1 , wherein the HDS engine is configured to:

receive a request to create a redundant storage for a primary storage subsystem and, in response, create the HDS including the at least one local HDS element that is included on the at least one local storage device, and the at least one networked HDS element that is included on the at least one networked storage device;

create and store the GPT entry in the GPT; and

periodically update the at least one local HDS element and the at least one networked HDS element with data provided on the primary storage subsystem.

receive a request to access the data in the primary storage subsystem; and

determine that the primary storage subsystem is unavailable and, in response, automatically provide access to the data included in the at least one local HDS element and the at least one networked HDS element.

7. The GPT based HDS system of claim 1 , wherein the second computing system includes:

a remote access controller that is configured, when an operating system for the second computing system is unavailable, to:

receive the GPT entry and the authorization credentials;

determine that the authorization credentials allow access to the HDS and, in response, provide access to the at least one local HDS element that is included on the at least one local storage device, and provide access to the at least one networked HDS element that is included on the at least one networked storage device.

8. An Information Handling System (IHS), comprising:

a communication system;

at least one local storage device;

a processing system that is coupled to the communication system and the at least one storage device; and

a memory system that is coupled to the processing system and that includes instruction that, when executed by the processing system, cause the processing system to:

receive a GPT entry and authorization credentials;

determine that the authorization credentials allow access to a Hidden Data Store (HDS) and, in response, access a Globally Unique Identifier (GUID) partition table (GPT) that includes the GPT entry that identifies: (1) at least one local HDS element that provides the HDS and that is included on at least one local storage device included in the first computing system, and: (2) at least one networked HDS element that provides the HDS and that is included on at least one networked storage device that is coupled to the communication system; and

providing access to the at least one local HDS element that is included on the at least one local storage device, and providing access to the at least one networked HDS element that is included on the at least one networked storage device.

9. The IHS of claim 8 , further comprising:

a local HDS element database that associates the at least one local HDS element identified by the GPT entry with the at least one local storage device; and

a networked HDS element database that associates the at least one networked HDS element identified by the GPT entry with the at least one networked storage device.

10. The IHS of claim 9 , further comprising:

a remote access controller that is configured to utilize the networked HDS element database to provide access to the at least one networked HDS element that is included on the at least one networked storage device.

11. The IHS of claim 8 , wherein the memory system includes instruction that, when executed by the processing system, cause the processing system to:

receive a request to create a redundant storage for a primary storage subsystem and, in response, create the HDS including the at least one local HDS element that is included on the at least one local storage device, and the at least one networked HDS element that is included on the at least one networked storage device;

create and store the GPT entry in the GPT; and

periodically update the at least one local HDS element and the at least one networked HDS element with data provided on the primary storage subsystem.

12. The IHS of claim 11 , wherein the memory system includes instruction that, when executed by the processing system, cause the processing system to:

receive a request to access the data in the primary storage subsystem; and

determine that the primary storage subsystem is unavailable and, in response, automatically provide access to the data included in the at least one local HDS element and the at least one networked HDS element.

13. The IHS of claim 12 , wherein the memory system includes instruction that, when executed by the processing system, cause the processing system to provide an operating system, and wherein the IHS further comprises:

a remote access controller that is configured, when the operating system is unavailable, to:
