Previously, it was reported on the official website that the NVME testing environment with 11 nodes reached its maximum speed, but now it is gone. The world's first NVME RAID card, how to test environments with more than 3 nodes? Is there any relevant introduction?
Does Starwind support more than 3 Nodes？

The mirror is done over a maximum 3 nodes. It simply does not make sense to sacrifice the storage resources of so many nodes.
For more nodes, StarWind VSAN devices can be configured as a grid (see more at https://www.starwindsoftware.com/resour ... hitecture/). That's how the system was configured for this series https://www.starwindsoftware.com/hyperc ... high-score.

Is there a detailed explanation? I didn't understand
Does starwind support distribution?how to do?thanks

Please have a look at a GRID concept https://www.starwindsoftware.com/resour ... hitecture/. In a nutshell, you create a set of 2-way-mirrored devices and split them across multiple nodes. Say, there are nodes A, B, C, and D, with the devices called 1, 2, 3, and 4.
GRID implies that 1 is replicated between A and B, 2 is between B and C, 3 is replicated between C and D, and 4 is between D and A.
StarWind VSAN allows for active-active replicated storage. Replication implies that there is an identical data set on each replication partner. In other words, you sacrifice storage for data redundancy. That is why a mirror between 11 nodes does not make sense.
You still can connect the storage replicated between 2 nodes to any other node in the cluster.

Which version supports the operation you mentioned? A, B, C, D and operations such as 1, 2, 3, 4. Does CVM15469 support them?

All StarWind VSAN versions support this use case. 15469 does support it.

Thanks

If deployed in this way, I would like to know the read and write patterns of the disks connected to the client? How are reads and writes allocated to each machine

Data is accessible from both nodes and its access partners are vastly determined by MPIO and path availability as paths from each node are connected to the initiator.
I would suggest booking a demo with one of our techs here https://www.starwindsoftware.com/v17-request-live-demo or reaching out to the person who provided you with the key to book it.
