Abstract

In an approach for provisioning a server utilizing a virtual consistency group, a processor receives a request to provision a first server utilizing a first application consistency group, wherein the first application consistency group is a virtualized consistency group. A processor defines a storage consistency group. A processor assigns the first application consistency group to the storage consistency group. A processor provisions the first server. A processor assigns to the provisioned first server, storage specified by the first application consistency group.

First claim

What is claimed is:

1 . A method for provisioning a server utilizing a virtual consistency group, the method comprising:
receiving a request to provision a first server utilizing a first application consistency group, wherein the first application consistency group is a virtualized consistency group; defining, by one or more processors, a storage consistency group; assigning, by one or more processors, the first application consistency group to the storage consistency group; provisioning, by one or more processors, the first server; and assigning, by one or more processors, to the provisioned first server, storage specified by the first application consistency group.

2 . The method of claim 1 , further comprising:
receiving a request to provision a second server utilizing the first application consistency group; provisioning, by one or more processors, the second server; and assigning, by one or more processors, to the provisioned second server, storage specified by the first application consistency group.

3 . The method of claim 1 , further comprising:
receiving a request to provision a second server utilizing a second application consistency group; determining, by one or more processors, the storage consistency group has available storage for the second application consistency group; assigning, by one or more processors, the second application consistency group to the storage consistency group; provisioning, by one or more processors, the second server; and assigning, by one or more processors, to the provisioned second server, storage specified by the second application consistency group.

4 . The method of claim 1 , wherein the first server is selected from the group consisting of a virtual machine and a bare-metal server.

5 . The method of claim 1 , wherein the first application consistency group includes storage across multiple storage tiers.

6 . The method of claim 1 , wherein the step of defining a storage consistency group is supported by a storage virtualizer.

7 . The method of claim 1 , wherein assigning the first application consistency group to the storage consistency group enables unilaterally provisioning computing capabilities.

8 . A computer program product for provisioning a server utilizing a virtual consistency group, the computer program product comprising:
one or more computer readable storage media and program instructions stored on the one or more computer readable storage media, the program instructions comprising: program instructions to receive a request to provision a first server utilizing a first application consistency group, wherein the first application consistency group is a virtualized consistency group; program instructions to define a storage consistency group; program instructions to assign the first application consistency group to the storage consistency group; program instructions to provision the first server; and program instructions to assign to the provisioned first server, storage specified by the first application consistency group.

9 . The computer program product of claim 8 , further comprising:
program instructions, stored on the one or more computer readable storage media, to receive a request to provision a second server utilizing the first application consistency group; program instructions, stored on the one or more computer readable storage media, to provision the second server; and program instructions, stored on the one or more computer readable storage media, to assign to the provisioned second server, storage specified by the first application consistency group.

10 . The computer program product of claim 8 , further comprising:
program instructions, stored on the one or more computer readable storage media, to receive a request to provision a second server utilizing a second application consistency group; program instructions, stored on the one or more computer readable storage media, to determine the storage consistency group has available storage for the second application consistency group; program instructions, stored on the one or more computer readable storage media, to assign the second application consistency group to the storage consistency group; program instructions, stored on the one or more computer readable storage media, to provision the second server; and program instructions, stored on the one or more computer readable storage media, to assign to the provisioned second server, storage specified by the second application consistency group.

11 . The computer program product of claim 8 , wherein the first server is selected from the group consisting of a virtual machine and a bare-metal server.

12 . The computer program product of claim 8 , wherein the first application consistency group includes storage across multiple storage tiers.

13 . The computer program product of claim 8 , wherein program instructions to define a storage consistency group are supported by a storage virtualizer.

14 . The computer program product of claim 8 , wherein program instructions to assign the first application consistency group to the storage consistency group enable unilaterally provisioning computing capabilities.

15 . A computer system for provisioning a server utilizing a virtual consistency group, the computer system comprising:
one or more computer processors, one or more computer readable storage media, and program instructions stored on the one or more computer readable storage media for execution by at least one of the one or more processors, the program instructions comprising: program instructions to receive a request to provision a first server utilizing a first application consistency group, wherein the first application consistency group is a virtualized consistency group; program instructions to define a storage consistency group; program instructions to assign the first application consistency group to the storage consistency group; program instructions to provision the first server; and program instructions to assign to the provisioned first server, storage specified by the first application consistency group.

16 . The computer system of claim 15 , further comprising:
program instructions, stored on the one or more computer readable storage media, to receive a request to provision a second server utilizing the first application consistency group; program instructions, stored on the one or more computer readable storage media, to provision the second server; and program instructions, stored on the one or more computer readable storage media, to assign to the provisioned second server, storage specified by the first application consistency group.

17 . The computer system of claim 15 , further comprising:
program instructions, stored on the one or more computer readable storage media, to receive a request to provision a second server utilizing a second application consistency group; program instructions, stored on the one or more computer readable storage media, to determine the storage consistency group has available storage for the second application consistency group; program instructions, stored on the one or more computer readable storage media, to assign the second application consistency group to the storage consistency group; program instructions, stored on the one or more computer readable storage media, to provision the second server; and program instructions, stored on the one or more computer readable storage media, to assign to the provisioned second server, storage specified by the second application consis
