Abstract

The present invention is a method of creating and assigning a class of storage that is defined by the customer at initialization, such that specific object code is assigned to and used by the devices in a class of storage and such that the devices themselves are grouped according to class of storage. This method provides the customer with greater system design flexibility over conventional naming standards and also provides greater data integrity and security. The method of the present invention includes the steps of assigning a class of storage label, storing the class of storage label, determining whether the device is the correct class of storage for the assigned sub-device group, delivering an error message if the class of storage is incorrect, and assigning the device to a sub-device group, if the class of storage is correct.

Claims

1. A method for classifying each of a plurality of networked devices, comprising:

creating a plurality of classification categories to describe the properties of each of the plurality of networked devices;

assigning a classification label to a device of the plurality of networked devices, the classification label referencing one or more of the plurality of classification categories;

storing assignment data on the network controller; and

grouping the device with other similarly assigned devices of the plurality of networked devices.

2. The method of claim 1, wherein the step of creating a plurality of classification categories is performed at a terminal remote from the network controller.

3. The method of claim 1, wherein the step of assigning a classification label is performed manually by a user.

4. The method of claim 1, wherein the step of grouping the device further comprises ensuring that the device is not already a member of a group of other devices of the plurality of networked devices.

5. The method of claim 4, wherein an error signal is generated if the device is either already a member of a group of other devices of the plurality of networked devices or if the device is assigned a classification label that differs from the classification label of the other devices of the plurality of networked devices.

6. The method of claim 1, wherein the network controller is a redundant array of independent disks (RAID) controller, and the plurality of networked devices are storage devices in a RAID system.

7. A system for classifying each of a plurality of networked devices, comprising:

a plurality of networked devices;

a network controller configured to store a plurality of classification categories that describe the properties of each of the plurality of networked devices;

a remote user configured to both assign a classification label to a device of the plurality of networked devices, the classification label referencing one or more of the plurality of classification categories, and to group the device among other similarly assigned devices of the plurality of networked devices; and

communication means to allow transmission of signals between the remote user and the network controller, and between the network controller and each of the plurality of networked devices.

8. The system of claim 7, wherein the assignment of a classification label is performed manually by the remote user.

9. The system of claim 7, wherein the remote user further ensures that the device is not already a member of a group of other devices of the plurality of networked devices.

10. The system of claim 9, wherein the network controller generates an error signal if the device is either already a member of a group of other devices of the plurality of networked devices or if the device is assigned a classification label that differs from the classification label of the other devices of the plurality of networked devices.

11. The system of claim 7, wherein the network controller is a redundant array of independent disks (RAID) controller, and the plurality of networked devices are storage devices in a RAID system.
