What is the maximum host cluster size to run a VSAN?

The maximum host cluster size to run a Virtual Storage Area Network (VSAN) is indeed 64. This limitation is important for maintaining performance and manageability within a cluster. In a VSAN environment, each host in the cluster has a role in managing and serving the virtual storage resources, and having too many hosts can lead to increased complexity, management overhead, and potential performance bottlenecks.

Maintaining a maximum of 64 hosts allows for efficient distribution of storage and compute resources while keeping the cluster manageable. This number is derived from the architectural design of the VSAN technology, which is optimized to provide reliable and scalable storage solutions within this host limit.

Understanding the cluster size limitations is crucial for deploying a VSAN effectively, ensuring that it meets the needs of the workloads it serves without compromising on performance or operational efficiency.
