Application-specific workload-based I/O performance management
View Patent ↗Techniques and mechanisms for establishing and implementing performance objectives for an application based at least in part on a workload type of the application. A system includes a storage system on which an application imposes a workload by utilizing storage resources of the storage system, and a performance level has been associated with the application. A workload type is associated with the application based on the type of workload, and a performance objective is determined for the application based on the performance level and the workload type of the application. The storage resources are manipulated to achieve the performance objective.
1. For a system including a storage system on which an application imposes a workload by utilizing storage resources of the storage system, wherein the storage resources comprise at least two physical storage devices of different types having different performance characteristics, and wherein a performance level has been associated with the application, a method comprising acts of:
associating a workload type with the application based on the type of workload, wherein the workload type includes storage system performance metrics and storage system data services associated with the application;
determining a performance objective for the application based on a combination of the performance level and the workload type associated with the application;
manipulating the storage resources to achieve on an ongoing basis the performance objective, wherein manipulating the storage resources includes dynamically allocating different types and amounts of physical storage resources allocated to a storage group associated with the application; and
allocating to the application an amount of storage from each of at least one of the at least two physical storage devices based at least on device type and the determined performance objective.
2. The method of claim 1 , further comprising acts of:
monitoring performance of the workload; and
adjusting the performance objective based at least on part on the monitoring.

monitoring performance of the workload; and
iteratively performing the act of allocating based at least in part on the act of monitoring.
4. The method of claim 1 , wherein the system comprises a storage group comprising one or more virtual storage units, and wherein the storage group is associated with the application, and
wherein the acts of associating a workload type with the application comprises associating the workload type with the storage group.
5. The method of claim 1 , wherein the workload type is based at least in part on one or more data services provided for the application as part of the workload.
6. The method of claim 1 , wherein the performance objective is a range of response time for I/O operations of the application on the storage system.
7. The system of claim 1 , further comprising:
fourth logic to monitor performance of the workload; and
fifth logic to adjust the performance objective based at least on part on the monitoring.
8. A storage system, comprising:
storage resources, wherein the storage resources comprise at least two physical storage devices of different types having different performance characteristics, and wherein an application imposes a workload on the storage system by utilizing the storage resources, and wherein a performance level has been associated with the application;
first logic to associate a workload type with the application based on the type of workload, wherein the workload type includes storage system performance metrics and storage system data services associated with the application;
second logic to determine a performance objective for the application based on a combination of the performance level and the workload type associated with the application;
third logic to manipulate the storage resources to achieve on an ongoing basis the performance objective, wherein manipulate the storage resources includes dynamically allocating different types and amounts of physical storage resources allocated to a storage group associated with the application; and
fourth logic to allocate to the application an amount of storage from each of at least one of the at least two physical storage devices based at least on device type and the determined performance objective.
9. The system of claim 8 , further comprising:
fourth logic to monitor performance of the workload,
wherein the third logic is operative to iteratively perform the allocation based at least in part on the monitoring.
10. The system of claim 8 , wherein the system comprises a storage group comprising one or more virtual storage units, and wherein the storage group is associated with the application, and
wherein the first logic is operative to associate the workload type with the application comprises by associating the workload type with the storage group.
11. The system of claim 8 , wherein the workload type is based at least in part on one or more data services provided for the application as part of the workload.
12. The system of claim 8 , wherein the performance objective is a range of response time for I/O operations of the application on the storage system.
13. A non-transitory computer-readable medium encoded with computer-executable instructions that, as a result of being executed by a computer, control the computer to perform, for a system including a storage system on which an application imposes a workload by utilizing storage resources of the storage system, wherein the storage resources comprise at least two physical storage devices of different types having different performance characteristics, and wherein a performance level has been associated with the application, a method comprising acts of:
associating a workload type with the application based on the type of workload, wherein the workload type includes storage system performance metrics and storage system data services associated with the application;
determining a performance objective for the application based on a combination of the performance level and the workload type associated with the application;
manipulating the storage resources to achieve on an ongoing basis the performance objective, wherein manipulating the storage resources includes dynamically allocating different types and amounts of physical storage resources allocated to a storage group associated with the application; and
allocating to the application an amount of storage from each of at least one of the at least two physical storage devices based at least on device type and the determined performance objective.
14. The non-transitory computer-readable medium of claim 13 , wherein the method further comprises acts of:
monitoring performance of the workload; and
adjusting the performance objective based at least on part on the monitoring.
15. The non-transitory computer-readable medium of claim 13 , wherein the method further comprises acts of:
monitoring performance of the workload; and
iteratively performing the act of allocating based at least in part on the act of monitoring.
16. The non-transitory computer-readable medium of claim 13 , wherein the system comprises a storage group comprising one or more virtual storage units, and wherein the storage group is associated with the application, and
