Re: When to increase number of ports on standard vSwitch?

I have a question about the number of ports needed on a standard vSwitch. I have a cluster of 6 hosts; each host has 2 10G NICs (each host is ESXi 5.1 - not U1). On each host I have a standard vswitch defined for use only  by the VMs (i.e., the management network and the vMotion network each has their own separate NICs, an active and a standby, and standard vswitches). The cluster has 128 VMs and templates in total. Each of these vswitches is defined with the default of 120 ports. This should be enough, correct? Unless I do something completely idiotic, like trying to run all the VMs on only 1 host, I should have enough ports available. Right now, I am averaging about 20-25 VMs on a host at any one time. All the VMs have only 1 NIC installed. So each individual switch should only have 20-25 ports in use at any one time.

 

Is that correct?

 

Correct.

 

If I do decide to increase the number of ports, I would just need to change the configuration and choose a higher value (say 248), and then migrate off all the VMs, put the host in maintenance mode, and reboot the host, in order for the changes to take effect.

 

Correct
