Connecting ESX Host to SAN switches.
I would like to know how you set up SAN Switch for ESX Hosts. I believe the VLAN where the ESX hosts are on, for instance VLAN 10, should also exist on SAN switch.
How do you configure SAN switch (Cisco) for each VLAN matching the VLANs on ESX Hosts. I have heard about Zoning, then heard about the recommendation to have ESX Hosts in each VLAN map to the same VLAN on SAN switch. Now it is like I am confused which one should be done? Zoning or VLAN to VLAN mapping, or they are 2 different tasks?
Zoning is a Fibre Channel term.
When setting up storage you want the storage network to be completely isolated, and ONLY carry iSCSI traffic.
This could be done with VLANs, if you are short of physical network ports.
So you would then create a unique VLAN, e.g. 580
The only ports which need to be on this VLAN, are the iSCSI VMKernel Portgroups on the Host.
No other VLANS need to be configured on the host.
