Copy offload for disparate offload providers

摘要

Aspects of the subject matter described herein relate to offload technology. In aspects, a source offload provider may transfer bulk data to a destination offload provider even if the offload providers are different and independent from each other and have no prior knowledge of each other. In preparation for transferring bulk data, trust may be extended to the offload providers. After authentication, the offload providers may transfer all or a portion of the bulk data over a secure channel without the data traversing the initiator of the transfer.

主权项

1. A method implemented at least in part by a computer, the method comprising:
sending, by an initiator, a request for a token that represents immutable data as long as the token is valid; in response to the request, receiving the token from a source offload provider; providing the token to a destination offload provider with an instruction to copy at least a portion of the immutable data from the source offload provider to the destination offload provider, the source offload provider and the destination offload provider being independent of each other; and extending trust of the initiator to the source offload provider and to the destination offload provider such that the source offload provider trusts the destination offload provider as the source offload provider trusts the initiator and such that the destination offload provider trusts the source offload provider as the destination offload provider trusts the initiator.
