Capacity Offload Test

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 IO 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 storage optimization of the environment after deploying the Atlantis ILIO. The Capacity Offload 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 identify the efficiency of the Atlantis ILIO and figure out any storage optimization issues when there is a sudden decrease in the efficiency of the Atlantis ILIO.

Target of the test : An Atlantis ILIO server

Agent deploying the test : An internal agent

Outputs of the test : One set of results for the Atlantis ILIO server that is to be monitored.

Configurable parameters for the test

Parameter	Description
Test Period	How often should the test be executed.
Host	The IP address of the host for which this test is to be configured.
Port	The port at which the specified Host listens. By default, this is NULL.

Measurements made by the test

Measurement	Description	Measurement Unit	Interpretation
Capacity usage without ILIO	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 Capacity usage with ILIO measure when compared to the Capacity usage without ILIO, the higher the efficiency of the Atlantis ILIO server in the target environment. If the Capacity usage with ILIO exceeds the Capacity usage without ILIO, it is a cause of concern which requires further investigation.
Capacity usage with ILIO	Indicates the actual disk utilization of the virtual target environment when this server is deployed.	MB
Capacity savings	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 Capacity usage without ILIO and the Capacity usage with ILIO measures.
Percentage of capacity saved	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.
