Identity Data Management in a High Availability Network
First Claim
1. A network device in a high availability network, comprising:
- a removable first identity data storage module, the removable first identity data storage module including a TPM and associated with a first memory storage device, wherein identity data unique to the network device is written into the first memory storage device, wherein the removable first identity data storage module is installed in the network device the first time the network device is powered up; and
a removable first management module, the removable first management module associated with a TPM and a central processing unit, capable of running on only the first chassis, wherein the removable first management module is installed in the network device the first time the network device is powered up, wherein when the first network device is powered up, identity data from the first identity data storage module is migrated to the removable first management module.

Abstract
The present invention is a network device in a high availability network that includes a a removable first identity data storage module that includes a TPM and that is associated with a first memory storage device, wherein identity data unique to the network device is stored in the first memory storage device. The removable first identity data storage module is installed in the network device the first time the network device is powered up. The network device also includes a removable first management module, that includes a TPM and a central processing unit. The first management module is installed in the network device the first time the network device is powered up. When the network device is powered up for the first time, identity data from the first identity data storage module is migrated to the TPM of the first removable management module.

8. A method of sharing migratable data in a network device, including the steps of:
-
establishing that a first module and a second module are in the same chassis group so that identity information unique to the network device can be shared between a first module having a TPM and a second module having a TPM; and determining whether identity data unique to the network device should be migrated from a first module to a second module. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)

17. A method of defining a chassis group, where enrollment in the chassis group is defined at manufacture:
defining an identity for the chassis, the identity including identity information unique to the chassis, stored in a first memory storage device that is associated with an first identity data storage module, the first identity data storage module associated with a TPM, wherein the identity information is defined by and stored by the manufacturer of the chassis before shipment.
