Network speed requirements
vSAN supports the following configurations:
- Hybrid vSAN configurations have options for 1 GB or 10 GB Ethernet for network uplinks. The amount of activity on the vSAN might consume a 1 GB network, and could be the constraint in an I/O-intensive setup as follows:
- Rebuild, replication, and synchronization operations
- Critical and intensive real-time disk operations, such as cloning a VM
- Large environments with more VMs
- All-flash vSAN configurations are supported only with 10 GB Ethernet network uplinks. An all-flash configuration consumes good network bandwidth because of the increased speed of the disks in the configuration with improved performance.
A 10 GB network is needed to get the best performance (IOPS). ...
