Methods and apparatus for provisioning servers to clients

1. A method of provisioning a server to a client, comprising:

pre-booting a server of a server pool using a client-neutral operating system image, before the server is provisioned to the client;

provisioning the pre-booted server to a virtual network of the client; mounting client storage volumes to the provisioned server;

and processing a client-specific configuration file;

after pre-booting the server, but before provisioning the server to the virtual network of the client, hibernating the pre-booted server;

wherein provisioning the server to the virtual network of the client comprises awakening the server on the virtual network of client;

disabling I/O elements of the server and enabling an I/O element re-find upon server awakening.

2. The method of claim 1 , further comprising, prior to pre-booting the server, associating the client-neutral operating system image with the server.

3. The method of claim 1 , wherein the pre-booting begins a boot process that is continued by processing the client-specific configuration file.

4. The method of claim 1 , wherein processing the client-specific configuration file comprises killing processes that were started during the pre-boot of the server, but which are not required by a client-specific configuration specified in the client-specific configuration file.

5. The method of claim 4 , wherein processing the client-specific configuration file comprises starting client-specific processes that were not started during the pre-boot.

6. The method of claim 1 , wherein processing the client-specific configuration file comprises configuring processes that were started during the pre-boot of the server.

7. The method of claim 1 , wherein the pre-booting comprises starting all services that can be started in a client-neutral environment.

8. The method of claim 1 , wherein the pre-booting comprises starting all operating system services that i) can be started in a client-neutral environment, and ii) are believed to require more than a predetermined amount of time to start.

9. The method of claim 1 , wherein the pre-booting comprises starting client-dependent services using client-neutral data, and wherein processing the client-specific configuration file comprises replacing the client-neutral data with client-specific data.

10. The method of claim 9 , wherein the client-neutral and client-specific data comprise passwords.

11. The method of claim 9 , wherein the client-neutral data is replaced with the client-specific data during a SCSI bus pause.

12. The method of claim 1 , wherein the pre-booting comprises starting a web server.

13. A method of provisioning a server to a client, comprising:

pre-booting a number of servers in a server pool, before the number of servers are provisioned to one or more clients;

each of the number of servers being pre-booted using a client-neutral operating system image that has been associated with the server;

provisioning a first of the pre-booted servers to a virtual network of a first client;

mounting client storage volumes to the provisioned server;

and processing a client-specific configuration file of the first client;

after pre-booting the server, but before provisioning the server to the virtual network of the first client, hibernating the pre-booted server;

wherein provisioning the server to the virtual network of the first client comprises awakening the server on the virtual network of the first client;

disabling I/O elements of the server and enabling an I/O element re-find upon server awakening.

14. The method of claim 13 , wherein:

during the pre-booting of the number of servers, the servers are logged into via a client-neutral administrator login; and

after provisioning the first of the pre-booted servers to the virtual network of the first client, the client-specific configuration file is processed via a client-specific login to the provisioned server.

15. The method of claim 13 , wherein:

different servers of the server pool are pre-booted using images of different operating systems; and

if the first client needs a server configured with a particular operating system, provisioning the virtual network of the first client a server that has been pre-booted with the particular operating system.

16. A data center comprising:

a server pool;

a storage pool;

a utility controller;

network edge equipment; and

machine executable instructions that, when executed by the controller, cause the data center to:

form a number of virtual networks and, via the network edge equipment,

provision the virtual networks to one or more clients of the data center;

pre-boot a number of servers in the server pool, before the number of servers are provisioned to one or more clients of the data center;

each of the number of servers being pre-booted using a client-neutral operating system image that has been associated with the server; and

in response to needs of the client(s), provision the pre-booted servers to one or more of the virtual networks,

wherein each pre-booted server is provisioned by i) mounting client storage image volumes maintained in the storage pool to the pre-booted server and

ii) processing a client-specific configuration file;

wherein the machine executable instructions further cause the data center to, after pre-booting the servers, but before provisioning the servers to the one or more virtual networks of the client(s), hibernate the pre-booted servers;

wherein provisioning the servers to the virtual network(s) of the client(s) comprising awakening the servers on the virtual network(s) of the client(s).

17. The data center of claim 16 , wherein the machine executable instructions further cause the data center to, prior to pre-booting the servers, associate the servers with the client-neutral operating system image.
