Physical Set up of ESX Host

Physical Set up of ESX Host

When setting up a new ESXi Host in Vmware Network, what kind of wiring you are supposed to use. I mean you connect a wire to the Storage Switch and another wire to the Network switch, so does each connection need an IP address? I know the connection to the network switch needs IP address which is called the Management Interface , what about the connection to the storage switch ?
I also want to know when you set up the redundancy, for instance you connect the ESX host to 2 Network Switches ( will you need 2 IP addresses on the Host ?)
The same for the connection to Storage switch :can we connect ESX host to 2 storage switches, or we can just connect the Storage switches to the Network Switches , and this will take care of the connections of ESX host to the storage device?

Any clarification will be very much appreciated.

Thank you

What you are referring to is HOST VMKernel Portgroups, and their resilience, and for resilience we can use two VMKernel Portgroups and two IP Addresses, or we can use TEAMING and a single IP Address.

Storage depends on the iSCSI or NFS storage you are using as to how you provide that resilience, as teaming is not support or recommended for iSCSI.

Answered above.

Usually 1 IP for Management Network - Teamed.

Usually 2 IP for iSCSI Network - Not Teamed (depends on SAN)

Usually 1 or 2 IP for NFS Network - Teamed or Not Teamed (depends on NAS)

When we refer to storage, we refer to paths to storage!

if we use two vmkernel portgroups and use teaming with single IP address, can we still  connect the ESX host to 2 different Network switches
for redundancy. if one Network switch goes down, the ESX host will still be able to use the other Network switch to stay up in the network.

regarding Storage terminology, I know we have SAN and also NAS. I believe SAN is more expensive and faster than NAS. So NFS is used with SAN and iSCSI is used with NAS ?

Also, can we connect the Storage switch to Network Switches (on which ESX hosts are already connected to) instead of connecting ESX hosts separately to Storage switch and to Network Switch ?

yes, but you only need a single IP Address, which is teamed using two physical network interfaces, to two different physical switches.

Quite simple iSCSI is Block Transfer e.g. it's a SAN. - Storage Area Network

NFS is File Transfer it's a NAS. - Network Attached Storage

As for which is fastest, iSCSI or NFS - depends.... what has confused the industry, as you now have Hybrid SAN/NAS, which can do FC, iSCSI and NFS, and CIFS all in the same unit. These units can be more expensive, or less expensive than SANs or NAS

Also, can we connect the Storage switch to Network Switches (on which ESX hosts are already connected to) instead of connecting ESX hosts separately to Storage switch and to Network Switch ?

Yes, but in an ideal world, or best practice, recommended you would have separate storage network!
