Can C9300-NM-8X SFP+ 10G ports be used as downlinks in a C9300?

[Red999]

We're planning to buy C9300 modular switches and adding C9300-NM-8X modules to get 8x SFP+ 10G ports.  Can these ports be used as downlinks to connect to our NAS and hypervisors?

Also, can the C9300 switches handle the bandwidth of having all 24 Multigigabit ports in use while the module has all 8 SFP+ ports in use and while stacked with one or two other C9300 switches which also have all 24 Multigabit ports and 8SFP+ ports in use?

Can be done but make sure to enable QoS (and regularly tune QoS).

Catalyst series switches are not designed for storage, servers and VM connectivity. If you have not purchase the equipment yet, take a look at the Nexus series for this type of use.

agree with @Reza Sharifi , these are enterprise switches ( Lan access) - this can be used for your requirement, but not designed as mentioned.
