Can we connect VMware hosts directly on core switch?
Hi,
I have 10 ESXi hosts which are connected to a switch and the switch is connected to a core switch.
My question is, can we connect the ESXi hosts directly to the core switch? Is it recommended, if not why? What is the pros and cons?

Of course it is best to have as few switches as possible between two communicating devices, and VM hosts usually run VMs most devices will want to talk to. So yes, put them in the middle of all switches.
Agreed, check the config on the switches though, make sure you understand how VLANS are trunked, and port groups are setup etc, to avoid any networking problems.
As Qlemo points out, building network redundancy in is good design, In our DCs I cable ESX boxes to alternate top of rack cabinets is drives the DC staff crazy :)

So it is not recommended to plug VM hosts directly on the core switch?

I have 2 network core switches.
Then it's best to use redundant connections to both, as shown above. How you achieve redundancy for the core switches themselves does not matter.

I'm not network expert that is why I need different opinions and want to see what others companies and others experts have and think.
I understand the redundancy part and adding switches are required if I have others devices to connect: telephony, physical servers, printers, etc.
Im my case there are enough ports on the core switches (2 core switches x 16 ports). In case we need more port maybe adding a normal switches or purchase an extra core switch will be required.
