Hello everyone,
We have an environment that consists of more than 100 VMs with a significant amount in TB in total. Analyzing the documentation https://documentation.commvault.com/2023e/expert/1661_hardware_specifications_for_virtual_server_agent.html, it only informs the sizing of the VSA and its capacity for FET.
We have implemented 1 VSA with the Medium specification, however, when running some Jobs, we noticed that only 5 VMs at a time are executed and this is the number of Data Readers for VMs Groups for all hypervisors standard, as mentioned in the documentation: https://documentation.commvault.com/2023/essential/107675_default_number_of_data_readers_for_vm_groups.html
Also, the transport mode is mixed, some VMs are using nbd others are using hotadd.
Because of this, we are concerned that the backups of this environment will take too long to protect the entire environment. So, thinking about this scenario, I was left with doubts about the number of VSAs needed to implement in the environment, in addition to its Sizing.
Note: We only have 1 MediaAgent at the moment, based on what is also stated in the documentation about its Sizing.
Thanks,
Antonio.
