Abstract

Mass storage is allocated to a logical server. The logical server is deployed to a real server.

Claims

1. A method comprising:

allocating a mass-storage resource to an undeployed logical server so that, while undeployed, said logical server specifies mass-storage information identifying said mass-storage resource in association with a network identity of said logical server, said logical server being stored in a logical-server database, said database storing plural logical servers, each of said logical servers specifying a network identity and resource requirements for a real server, each of said logical servers being configured to serve as a management abstraction for a workload container in the form of a real server, said logical servers being deployable to but not being respective real servers, said real servers including physical servers and virtual servers, said logical servers having alternative deployed and undeployed states; and

deploying said logical server to a real server meeting said resource requirements when said mass storage resources are allocated to said logical server.

2. A method as recited in claim 1 wherein said network identity is an WWN and said mass-storage information specifies a storage-array and a logical-unit number (LUN).

3. A method as recited in claim 2 wherein said real server is a virtual-machine server.

4. A method as recited in claim 3 wherein said virtual-machine server adopts said WWN.

5. A method as recited in claim 2 wherein said real server is a hardware server.

6. A method as recited in claim 5 wherein said WWN is an abstraction WWN for a hardwired WWN of said hardware server.

7. A method as recited in claim 2 wherein said requesting involves a system administrator making a request to a storage administrator, said administrators being different people.

8. A method as recited in claim 2 further comprising:

prior to said allocating, creating said undeployed logical server; and

after said creating, requesting creation of said mass-storage resource;

after said requesting, creating said mass-storage resource corresponding to said mass-storage identity; and

while said logical server is undeployed, updating said logical server with said mass-storage information.

9. A method as recited in claim 1 further comprising, after said allocating, a system administrator receiving a request for a new server, said deploying occurring in response to said request.

10. A method as recited in claim 1 further comprising deploying said logical server at different times to a physical server and to a virtual server.

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

allocate a mass-storage resource to a logical server while said logical server is undeployed so that said logical server specifies a network identity for said logical server and mass-storage information identifying said mass-storage resource, said logical server being stored in a logical-server database, said database storing plural logical servers, said logical servers specifying respective network identities and respective resource requirements for respective real servers, each of said logical servers being configured to serve as a management abstraction for a workload container in the form of a real server, said logical servers being deployable to but not being respective real servers, said real servers including physical servers and virtual servers, said logical servers having alternative deployed and undeployed states; and

deploy said logical server to a real server meeting said resource requirements when said mass storage resources are allocated to said logical server.

12. A system as recited in claim 11 wherein said code is further to, before the allocating:

create said logical server with said network identity, said network identity including a world-wide name (WWN); and

request said mass-storage resource be allocated to said WWN.

13. A system as recited in claim 12 wherein said real server is a virtual-machine server.

14. A system as recited in claim 13 wherein said virtual-machine server adopts said WWN.

15. A system as recited in claim 12 wherein said real server is a hardware server.

16. A system as recited in claim 15 wherein said WWN is a abstraction WWN for a hardwired WWN of said hardware server.

17. A system as recited in claim 12 wherein said code is further to:

in response to said request, create said mass-storage resource specified by said mass-storage information, said mass-storage information including an mass-storage identity for a storage array and a logical-unit number (LUN); and

while said logical server is undeployed, update said logical server with said mass-storage information.

18. A system as recited in claim 11 further comprising said processor.

19. A system as recited in claim 11 wherein said code is further configured to deploy said logical server at different times to a physical server and to a virtual server.

20. A system comprising:

at least one processor;

a real server manager to manage physical and virtual servers in response to real-server instructions;

a logical-server database, said database storing plural logical servers, each of said logical servers specifying a network identity and resource requirements for a real server, each of said logical servers being configured to serve as a management abstraction for a workload container in the form of a real server, said logical servers being deployable to but not being respective real servers, said real servers including physical servers and virtual servers, said logical servers having alternative deployed and undeployed states; and

a logical server manager to;

create logical servers so that each logical server has resource requirements and at least one network identity assigned to it,

receive logical-server instructions for managing said logical servers from an administrator,

translate at least some of said logical-server instructions into said real-server instructions, and

deploy a first logical server at different times to a physical server and to a virtual server.
