- Storage-compute integration: 2048
- Decoupled storage and compute: The multi-VW technology is used to support up to 256 VWs, each with up to 1,024 DNs. It is recommended that you limit VWs to 32 or fewer and DNs to 128 or fewer per VW. The total number of DNs of all VWs cannot exceed 2,048.

- Decoupled storage and compute:
The multi-VW technology can increase the number of concurrent requests. As the number of VWs increases, the number of concurrent requests can be increased accordingly. The total number of concurrent requests in a cluster is affected by the GTM/CCN queuing. The maximum number is 32,768. It is recommended that the number be no more than 8,192 (default value).
