The object and the value in which the targeted value is set are decided by the following procedures.
Extract the volume that the business application uses.
Decide the target response time (unit of millisecond) of the extracted volume.
Examples are as follows.
Configuration Example of Target Values of Business Application
This explains the introduction of automatic tuning with performance target values, in relation to the following environment that is operating business applications.
As a regular business, business application A is being operated on server Server_1.
The Tier pools that business application A uses are TrPool_1 and TrPool_2
FTV#0 and FTV#1 are present in TrPool_1, and business application A uses FTV#0 and FTV#1.
FTV#2 and FTV#3 are present in TrPool_2, and business application A uses FTV#2 and FTV#3.
Figure 5.1 Operation Model of Business Application
In relation to the above volumes, configure the target response time from the following perspectives.
Performance requirements of business application
Current performance value, interpreted from the performance graph
The target response time that each volume needs is decided from the performance requirement for business application A. In the example, it makes it to the target response time indicated in the following tables.
Tier Pool Name | FTV Name | Target Response Time |
|---|---|---|
TrPool_1 | FTV#0 | 10 msec |
FTV#1 | 20 msec | |
TrPool_2 | FTV#2 | - |
FTV#3 | 100 msec |
In accordance with the performance adjustments of the volumes to which target response times have been configured, the performance of other volumes sharing resources with these are also controlled.
The decided target response times are configured to the volumes and performance adjustments are conducted, and until the user determines that performance sufficient for the operation of business applications is reached, the configuration of target response times are repeated.
Command execution examples for Windows are described below.
A target response time of 10 msec will be configured in relation to FTV#0 present in TrPool_1.
>$INS_DIR\Common\bin\esfadm volume qosset -ipaddr 10.10.10.10 -volume 0 -resptime 10
A target response time of 20 msec will be configured in relation to FTV#1 present in TrPool_1.
>$INS_DIR\Common\bin\esfadm volume qosset -ipaddr 10.10.10.10 -volume 1 -resptime 20
A target response time of 100 msec will be configured in relation to FTV#3 present in TrPool_2.
>$INS_DIR\Common\bin\esfadm volume qosset -ipaddr 20.20.20.20 -volume 3 -resptime 100
