Virtualization and server imaging system for allocation of computer hardware and software
View Patent ↗A system for improving resource utilization across a cluster of interconnected symmetric multiprocessor (“SMP”) servers is provided. The system includes single system image (“SSI”) software that represents the cluster of SMP servers as a single virtual SMP server and virtualization software that partitions the virtual SMP server into virtual servers. The system may also include virtual infrastructure management software that is used to partition the virtual SMP server into the virtual servers. A method for using SMP servers is further provided. The method includes representing the SMP servers as a virtual SMP server and partitioning the virtual SMP server into virtual servers. The method may also include allocating and reallocating processes across the physical SMP servers.
1. A system, comprising:
a plurality of interconnected symmetric multiprocessor (“SMP”) servers;
single system image (“SSI”) software that represents and manages the plurality of SMP servers as a single virtual SMP server, wherein the single virtual SMP server comprises a single entry point to the plurality of SMP servers, a single file hierarchy, a single control point, a single memory space, single job management, and a single process space; and
virtualization software that partitions the virtual SMP server into a plurality of virtual servers, wherein each virtual server of the plurality of virtual servers comprises a virtual machine and an operating system executable on the virtual machine, and wherein the virtualization software performs translations to execute the operating system on at least one of the plurality of virtual servers.
2. The system of claim 1 , wherein each SMP server of the plurality of SMP servers executes an operating system kernel.
3. The system of claim 1 , further comprising virtual infrastructure management software, wherein the virtual infrastructure management software is used to partition the virtual SMP server into the plurality of virtual servers.
4. The system of claim 1 , wherein the SSI software dynamically allocates and reallocates processes of the plurality of virtual servers across the plurality of SMP servers responsive to changes in system resource availability.
5. The system of claim 1 , wherein the SSI software automatically reallocates a process of a virtual server of the plurality of virtual servers from one SMP server of the plurality of SMP servers to another SMP server of the plurality of SMP servers responsive to a change in system resource availability.
6. The system of claim 1 , wherein a virtual server of the plurality of virtual servers is guaranteed a minimum amount of system resources of the virtual SMP server.
7. The system of claim 1 , wherein a virtual server of the plurality of virtual servers is given more system resources of the virtual SMP server if the virtual server can effectively use the additional system resources.
8. A method for using a plurality of symmetric multiprocessor (“SMP”) servers comprising:
representing and managing the plurality of SMP servers as a single virtual SMP server, wherein the single virtual SMP server comprises a single entry point to the plurality of SMP servers, a single file hierarchy, a single control point, a single memory space, single job management, and a single process space; and
partitioning, by virtualization software, the virtual SMP server into a plurality of virtual servers, wherein each virtual server of the plurality of virtual servers comprises a virtual machine and an operating system executable on the virtual machine, and wherein the virtualization software performs translations to execute the operating system on at least one of the plurality of virtual servers.
9. The method of claim 8 , wherein each SMP server of the plurality of SMP servers executes an operating system kernel.
10. The method of claim 8 , further comprising:
executing a process of a virtual server of the plurality of virtual servers on an SMP server of the plurality of SMP servers; and
automatically reallocating the process to another SMP server of the plurality of SMP servers during execution responsive to a change in system resource availability.
11. The method of claim 8 , further comprising:
dynamically allocating and reallocating system resources of the virtual SMP server across the plurality of virtual servers responsive to changes in availability of the system resources.
12. A system, comprising:
a plurality of interconnected symmetric multiprocessor (“SMP”) servers;
a virtual infrastructure that executes on the plurality of SMP servers, wherein the virtual infrastructure is provided in part by virtualization software; and
a plurality of virtual servers that execute on the virtual infrastructure,
wherein the virtual infrastructure manages the plurality of SMP servers as a single virtual SMP server and dynamically allocates and reallocates system resources of the virtual SMP server across the plurality of virtual servers;
wherein the single virtual SMP server comprises a single entry point to the plurality of SMP servers, a single file hierarchy, a single control point, a single memory space, single job management, and a single process space;
wherein each virtual server of the plurality of virtual servers comprises a virtual machine and an operating system executable on the virtual machine; and
wherein the virtualization software performs translations to execute the operating system on at least one of the plurality of virtual servers.
13. The system of claim 12 , wherein each SMP server of the plurality of SMP servers executes an operating system kernel.
14. The system of claim 12 , wherein the virtual infrastructure automatically reallocates a process of a virtual server of the plurality of virtual servers from one SMP server of the plurality of SMP servers to another SMP server of the plurality of SMP servers responsive to a change in availability of the system resources.
15. The system of claim 12 , wherein the virtual infrastructure provides a virtual server of the plurality of virtual servers a minimum amount of system resources of the virtual SMP server.
16. The system of claim 12 , wherein the virtual infrastructure provides a virtual server of the plurality of virtual servers more system resources of the virtual SMP server if the virtual server can effectively use the additional system resources.
17. The system of claim 12 , wherein a virtual server of the plurality of virtual servers is defined to require a minimum amount of system resources of the virtual SMP server and a maximum amount of system resources of the virtual SMP server, and
wherein the virtual infrastructure guarantees the minimum amount of system resources to the virtual server during execution and provides additional system resources to the virtual server up to the maximum amount if additional system resources are available.
