Abstract

Methods and systems for managing the allocated and unallocated server farms in a desktop virtualization system are provided herein. A server farm management device may store and maintain one or more unallocated server farm thresholds for the desktop virtualization system. The current number of unallocated server farms may be determined in response to a trigger or according to a predetermined schedule. When the number of unallocated server farms falls below a threshold, one or more new unallocated server farms may be created using the available servers in the desktop virtualization system. Thresholds may relate to overall number of unallocated server farms in the desktop virtualization system, as well as to the numbers of unallocated server farms of certain types or having certain characteristics.

Claims

1. A server farm management device for a desktop virtualization system, comprising:

a processor; and

memory storing computer readable instructions that, when executed by the processor, configure the server farm management device to;

retrieve a first threshold of unallocated server farms for the desktop virtualization system;

determine a current number of unallocated server farms in the desktop virtualization system;

compare the first threshold of unallocated server farms to the current number of unallocated server farms; and

based on the comparison, create one or more unallocated server farms in the desktop virtualization system.

2. The server farm management device of claim 1, the memory storing further computer readable instructions that, when executed by the processor, configure the server farm management device to:

detect an assignment of a tenant to a previously unallocated server farm in the desktop virtualization system; and

based on the detection of the assignment, trigger the comparison of the first threshold of unallocated server farms to the current number of unallocated server farms.

3. The server farm management device of claim 2, the memory storing further computer readable instructions that, when executed by the processor, configure the server farm management device to:

change a status for the allocated server farm stored at the server farm management device to indicate that the server farm has been allocated; and

decrement a number stored at the server farm management device corresponding to the current number of unallocated server farms in the desktop virtualization system.

4. The server farm management device of claim 2, wherein creating one or more unallocated server farms comprises:

determining one or more characteristics of the server farm allocated to the tenant of the desktop virtualization system; and

creating a first unallocated server farm having the same one or more characteristics of the allocated server farm.

5. The server farm management device of claim 4, wherein the one or more characteristics of the allocated server farm are selected from a group comprising:

a number of servers in the allocated server farm;

an isolation mode of the allocated server farm;

a set of applications available in the allocated server farm; and

a load balancing or election policy of the allocated server farm.

6. The server farm management device of claim 4, wherein creating the first unallocated server farms comprises:

identifying one or more available servers in the desktop virtualization system; and

retrieving and executing a server farm configuration script on the one or more available servers,

wherein at least one of the server farm configuration script or a set of parameters provided to the server farm configuration script is based on the one or more characteristics of the allocated server farm.

7. The server farm management device of claim 1, wherein comparing the first threshold of unallocated server farms to the current number of unallocated server farms comprises:

determining that there are zero unallocated server farms in the desktop virtualization system.

8. A method comprising:

retrieving, at a server farm management device, a first threshold of unallocated server farms for a desktop virtualization system;

determining, by the server farm management device, a current number of unallocated server farms in the desktop virtualization system;

comparing, by the server farm management device, the first threshold of unallocated server farms to the current number of unallocated server farms; and

based on the comparison, creating one or more unallocated server farms in the desktop virtualization system.

9. The method of claim 8, further comprising:

detecting an assignment of a tenant to a previously unallocated server farm in the desktop virtualization system; and

based on the detection of the assignment, triggering the comparison of the first threshold of unallocated server farms to the current number of unallocated server farms.

10. The method of claim 9, further comprising:

changing a status for the allocated server farm to indicate that the server farm has been allocated; and

decrementing a stored number corresponding to the current number of unallocated server farms in the desktop virtualization system.

11. The method of claim 9, wherein creating one or more unallocated server farms comprises:

determining one or more characteristics of the server farm allocated to the tenant of the desktop virtualization system; and

creating a first unallocated server farm having the same one or more characteristics of the allocated server farm.

12. The method of claim 11, wherein the one or more characteristics of the allocated server farm are selected from a group comprising:

a number of servers in the allocated server farm;

an isolation mode of the allocated server farm;

a set of applications available in the allocated server farm; and

a load balancing or election policy of the allocated server farm.

13. The method of claim 11, wherein creating the first unallocated server farms comprises:

identifying one or more available servers in the desktop virtualization system; and

retrieving and executing a server farm configuration script on the one or more available servers,

wherein at least one of the server farm configuration script or a set of parameters provided to the server farm configuration script is based on the one or more characteristics of the allocated server farm.

14. The method of claim 8, wherein comparing the first threshold of unallocated server farms to the current number of unallocated server farms comprises:

determining that there are zero unallocated server farms in the desktop virtualization system.

15. One or more computer readable media comprising computer readable instructions that, when executed, configure a server farm management device to perform:

retrieving a first threshold of unallocated server farms for a desktop virtualization system;

determining a current number of unallocated server farms in the desktop virtualization system;

comparing the first threshold of unallocated server farms to the current number of unallocated server farms; and

based on the comparison, creating one or more unallocated server farms in the desktop virtualization system.

16. The computer readable media of claim 15, comprising further computer readable instructions that, when executed, configure the server farm management device to perform:

detecting an assignment of a tenant to a previously unallocated server farm in the desktop virtualization system; and

based on the detection of the assignment, triggering the comparison of the first threshold of unallocated server farms to the current number of unallocated server farms.

17. The computer readable media of claim 16, comprising further computer readable instructions that, when executed, configure the server farm management device to perform:

changing a status for the allocated server farm stored at the server farm management device to indicate that the server farm has been allocated; and

decrementing a number stored at the server farm management device corresponding to the current number of unallocated server farms in the desktop virtualization system.

18. The computer readable media of claim 16, wherein creating one or more unallocated server farms comprises:

determining one or more characteristics of the server farm allocated to the tenant of the desktop virtualization system; and

creating a first unallocated server farm having the same one or more characteristics of the allocated server farm.

19. The computer readable media of claim 18, wherein the one or more characteristics of the allocated server farm are selected from a group comprising:

a number of servers in the allocated server farm;

an isolation mode of the allocated server farm;

a set of applications available in the allocated server farm; and

a load balancing or election policy of the allocated server farm.

20. The computer readable media of claim 18, wherein creating the first unallocated server farms comprises:

identifying one or more available servers in the desktop virtualization system; and

retrieving and executing a server farm configuration script on the one or more available servers,

wherein at least one of the server farm configuration script or a set of parameters provided to the server farm configuration script is based on the one or more characteristics of the allocated server farm.
