The following are the key requirements for this scenario:
Separate storage clusters for SSD, hybrid HDD, and HDD
Storage clusters should be on separate subnets
Storage should be distributed with High Availability and high scalability
For this scenario, each Proxmox node must have at least four network interface cards: three to connect three storage cluster subnets, and one to connect to Proxmox virtual environment. This example is for six virtual machines to have access to three different performing storages. The following table shows three Ceph clusters and their performance categories:
