Abstract

Example implementations relate to non-volatile storage of management data. In example implementations, a system is disclosed, the system including a plurality of computing devices, a management device, and a non-volatile memory including a plurality of management spaces corresponding to the plurality of computing devices. In example implementations, at least one of the plurality of management spaces is to be accessible by the management device and by the corresponding computing device, be inaccessible by computing devices other than the corresponding computing device, and store management data associated with the corresponding computing device.

First claim

What is claimed is:

1. A system comprising:
a plurality of computing devices;
a management device;
a non-volatile memory comprising a plurality of management spaces corresponding to the plurality of computing devices, wherein at least one management space is to:
be accessible by the management device and by the corresponding computing device,
be inaccessible by computing devices other than the corresponding computing device,
store management data associated with the corresponding computing devices; wherein:

the management data is encrypted with a public key; and
the corresponding computing device comprises a private key associated with the public key, wherein the private key is inaccessible by computing devices other than the corresponding computing device.

2. The system of claim 1 , wherein the management data is to be accessible by the management device at least when the corresponding computing device is powered off or is not operational.

3. The system of claim 1 , wherein the management data comprises state information indicating a current state of the corresponding computing device, and wherein the corresponding device is to:
detect a change in the current state; and update the state information based on the change.

4. The system of claim 1 , wherein:
the management data comprises upgrade data;
the corresponding device comprises at least one of a software component and a firmware component; and
the corresponding device is to upgrade the at least one of the software component and the firmware component based on the upgrade data.

5. The system of claim 1 , wherein the computing device comprises at least one management unit and at least one functional unit, and wherein the management space is to be accessible by the management unit and not to be accessible by the functional unit.

6. The system of claim 1 , wherein the corresponding computing device comprises a memory controller configured to map an internal address range associated with the management space.
