Measures reported by CapacityOffloadTest

Atlantis ILIO In-Memory Storage Optimization Technology improves how VMs consume storage in the datacenter by inserting a transparent software layer between the VM and underlying storage infrastructure. Atlantis ILIO applies multiple storage optimization technologies to boost performance and increase the available storage capacity provided to the application. At the same time, Atlantis ILIO dramatically reduces application I/O traffic on the storage and network infrastructure. In large virtual environments where the Atlantis ILIO is deployed, administrators may wish to monitor the efficiency of the Atlantis ILIO i.e., the I/O and storage optimization of the environment after deploying the Atlantis ILIO.

The CapacityOffloadTest test exactly does the same! Using this test, you can monitor the actual disk utilization of the target environment when the Atlantis ILIO is deployed and the apparent disk utilization if the Atlantis ILIO is not deployed. This test also helps the administrators to calculate the disk space saved by the Atlantis ILIO and the percentage of space saved. Using the metrics reported by this test, administrators can actually perform a comparative analysis of the usage of the Atlantis ILIO, deduce the efficiency of the Atlantis ILIO and figure out any I/O and storage optimization issues when there is a sudden decrease in the efficiency of the Atlantis ILIO.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Apparent_usage Indicates the disk utilization of the virtual target environment when this server is not deployed. MB The efficiency of the Atlantis ILIO can be determined by frequently analyzing the value of these measures. The lower the Actual_usage when compared to the Apparent_usage, the higher the efficiency of the Atlantis ILIO server in the target environment. If the Actual_usage exceeds the Apparent_usage, it is a cause of concern which requires further investigation.
Actual_usage Indicates the actual disk utilization of the virtual target environment when this server is deployed. MB
Capacity_off Indicates the total amount of disk space that is saved by using this server in the virtual target environment. MB A high value is desired for this measure. This value is the difference between the Actual_usage and the Apparent_usage measures.
Capacity_off_util Indicates the percent of disk space saved by using this server in the virtual target environment. Percent A high value is desired for this measure. The lower the value of this measure, the lesser is the impact of the Atlantis ILIO in the target environment i.e., the lesser is the efficiency of the Atlantis ILIO in the target environment.
