Abstract

A deployed logical server is created by importing specifications, including a first network identity, of a first real server so that the logical server is stored in a logical-server database. The initially deployed logical server is released from the real server, and a second network identity is assigned to the first real server. The logical server is redeployed on a second real server so that it continues to be associated, in the logical-server database, with the first network identity and respective compute, storage, and network requirements.

Claims

1. A method comprising:

creating a deployed logical server by importing specifications of a first real server so that said logical server is stored in a logical-server database, said specifications including a first network identity of said first real server, said logical-server database storing plural logical servers, said database associating each of said logical servers with a respective network identity and compute, storage and network requirements, said logical servers having alternative deployed and undeployed states, said logical servers, when deployed, serving as management abstractions for workload containers in the forms of real physical servers and real virtual servers;

releasing said logical server from said first real server so that said logical server is undeployed;

assigning a second network identity to said first real server; and

redeploying said logical server to a second real server so that said logical server continues to be associated, in said logical-server database, with said first network identity and respective compute, storage, and network requirements.

2. A method as recited in claim 1 wherein said first network identity is a World Wide Name (WWN) or a Media Access Control (MAC) address.

3. A method as recited in claim 1 wherein said first and second real servers are different but both meet the compute, storage, and network requirements for said logical server.

4. A method as recited in claim 3 wherein one of said first and second real servers is a hardware server and the other is a virtual-machine server.

5. A method as recited in claim 1 wherein, while said logical server is deployed to said second real server, said second real server effectively adopts a network identity formerly associated with said first real server.

6. A method as recited in claim 1 wherein, between said releasing and said redeploying, storing said logical server in a dormant state.

7. A system comprising non-transitory computer-readable storage media encoded with code to, when executed by a processor:

create a deployed logical server by importing specifications from a first real server so that said logical server is stored in a logical-server database storing plural logical servers, said specifications including a first network identity of said first real server, said database associating each of said logical servers with a network identity and compute, storage and network requirements, said logical servers having alternative deployed and undeployed states, said logical servers, when deployed, serving as management abstractions for workload containers in the forms of real physical servers and real virtual servers;

release said logical server from said first real server so that said logical server is undeployed;

assign a second network identity to said first real server; and

redeploy said logical server to a second real server so that said logical server continues to be associated, in said logical-server database, with said first network identity and respective compute, storage, and network requirements.

8. A system as recited in claim 7 wherein said code first network identity is a World Wide Name (WWN) or a Media Access Control (MAC) address.

9. A system as recited in claim 7 wherein said code is further to store said logical server in a dormant state in said database in association with its network identity and its compute, storage, and network requirements.

10. A system as recited in claim 7 further comprising said processor.

11. A system as recited in claim 7 wherein one of said first and second real servers is a hardware server and the other is a virtual-machine server.
