How Do I Add Shards to a Cluster DCS Redis Instance Without Changing the Memory?
After a Proxy Cluster or Redis Cluster instance is created, you can reduce the capacity of each shard and add more shards without changing the total memory.
For example, if an 8 GB instance has 4 shards and each shard is 2 GB, you can reduce the shard size to 1 GB and increase the shard quantity to 8.
A shard size of 1 GB cannot be changed.
Procedure
- Log in to the DCS console.
- Click in the upper left corner to select a region and a project.
- In the navigation pane, choose Cache Manager.
- Choose More > Modify Specifications in the row containing the desired DCS instance.
- On the displayed Modify Instance Specifications page, specify Shard Size and Instance Specification.

- Click Next, confirm the details, and click Submit.
The modification takes about 5 to 30 minutes to complete. After the modification is successful, the instance status changes to Running.
