To verify the current state of an OST client, you can check these two sources:

• DR Series system CLI, using the ost --show --clients command
• DR Series system GUI, displaying the Clients page

These sources display information about the connected and configured clients. For example, when a system is connected to multiple times, these sources show the number of connections to that client and the mode. You can also change the mode from dedupe to the other supported modes. When this is done the displayed mode will change, but any active connections will remain. There are essentially two possible modes: Dedupe and Passthrough. To verify the current mode of an OST client, you can check these two sources of client statistics:

• DR Series system CLI, using the stats --container --name command
• DR Series system GUI, displaying the Container Statistics page

In the Container Statistics page, click the Client Statistics tab (under Connection Type: OST) to display the Client Statistics table. If the Network Savings level in this table displays some savings and the displayed Bytes Ingested value is different from the displayed Bytes Transferred, this indicates that the OST clients are working in the Dedupe mode. If not, this indicates that the OST containers are working in the Passthrough mode.
