- نبذة مختصرة :
Proposed are a method and a device for managing the performance of a storage apparatus which uses a combination of different types of drive devices which mutually have different limits as its storage medium so that measures can be systematically taken against problems that may arise in the future as a result of the drive devices reaching their limit. Based on a premise of being able to tier two or more types of storage mediums which have mutually different rewriting limits and response performances and migrate data between the respective tiers according to the response performance, a performance management device estimates a decrement of a storage capacity pursuant to each of the two or more types of storage mediums reaching a rewriting limit, estimates a performance influence on the virtual volume and a timing of occurrence, and displays information related to the estimated performance influence and the timing of occurrence.

- Claim:
1. A performance management device of a storage apparatus comprising two or more types of storage mediums which have mutually different rewriting limits and response performances, wherein the storage apparatus provides, to a host computer connected to the storage apparatus, a virtual volume configuring a virtual logical volume by using the two or more types of storage mediums, wherein, when a write request is issued from the host computer to write data into an unwritten address of the virtual volume, the storage apparatus writes data according to the write request in a storage area of a storage medium among the two or more types of storage mediums which is unused and which has not yet reached a writing limit, wherein, according an IO load of the host computer in each storage area of each of the two or more types of storage mediums, the storage apparatus migrates a storage location of data from a storage area of a storage medium with a lower response performance to a storage area of a storage medium with a higher response performance and which has not yet reached a writing limit, or from a storage area of a storage medium with a higher response performance to a storage area of a storage medium with a lower response performance and which has not yet reached a writing limit, and wherein the performance management device includes: a performance influence estimation unit which estimates a decrement of a storage capacity pursuant to each of the two or more types of storage mediums reaching a rewriting limit, and estimates a performance influence on the virtual volume and a timing of occurrence thereof; and a performance influence display unit which displays information related to the estimated performance influence and the timing of occurrence thereof.
- Claim:
2. The performance management device of a storage apparatus according to claim 1 , wherein the performance influence display unit displays a timing in which a response performance degradation of a volume will begin.
- Claim:
3. The performance management device of a storage apparatus according to claim 1 , wherein the performance influence display unit displays a timing in which a volume will no longer satisfy a target response performance.
- Claim:
4. The performance management device of a storage apparatus according to claim 1 , wherein the performance influence display unit displays a capacity of an expansion flash drive required for extending a target achievement period to a pre-set timing.
- Claim:
5. The performance management device of a storage apparatus according to claim 1 , wherein the performance influence display unit displays a target achievement period of a volume based on a capacity of a designated expansion flash drive.
- Claim:
6. The performance management device of a storage apparatus according to claim 1 , wherein the performance influence display unit displays a pool migration plan of a volume required for extending a target achievement period to a pre-set timing.
- Claim:
7. A performance management method based on a performance management device for managing a storage apparatus comprising two or more types of storage mediums which have mutually different rewriting limits and response performances, wherein the storage apparatus provides, to a host computer connected to the storage apparatus, a virtual volume configuring a virtual logical volume by using the two or more types of storage mediums, wherein, when a write request is issued from the host computer to write data into an unwritten address of the virtual volume, the storage apparatus writes data according to the write request in a storage area of a storage medium among the two or more types of storage mediums which is unused and which has not yet reached a writing limit, wherein, according an IO load of the host computer in each storage area of each of the two or more types of storage mediums, the storage apparatus migrates a storage location of data from a storage area of a storage medium with a lower response performance to a storage area of a storage medium with a higher response performance and which has not yet reached a writing limit, or from a storage area of a storage medium with a higher response performance to a storage area of a storage medium with a lower response performance and which has not yet reached a writing limit, and wherein the performance management method includes: a performance influence estimation step of estimating a decrement of a storage capacity pursuant to each of the two or more types of storage mediums reaching a rewriting limit, and estimating a performance influence on the virtual volume and a timing of occurrence thereof; and a performance influence display step of displaying information related to the estimated performance influence and the timing of occurrence thereof.
- Claim:
8. The performance management method of a storage apparatus according to claim 7 , wherein, in the performance influence display step, the performance management device displays a timing in which a response performance degradation of a volume will begin.
- Claim:
9. The performance management method of a storage apparatus according to claim 7 , wherein, in the performance influence display step, the performance management device displays a timing in which a volume will no longer satisfy a target response performance.
- Claim:
10. The performance management method of a storage apparatus according to claim 7 , wherein, in the performance influence display step, the performance management device displays a capacity of an expansion flash drive required for extending a target achievement period to a pre-set timing.
- Claim:
11. The performance management method of a storage apparatus according to claim 7 , wherein, in the performance influence display step, the performance management device displays a target achievement period of a volume based on a capacity of a designated expansion flash drive.
- Claim:
12. The performance management method of a storage apparatus according to claim 7 , wherein, in the performance influence display step, the performance management device displays a pool migration plan of a volume required for extending a target achievement period to a pre-set timing.
