Wiring ESX Hosts.

Wiring ESX Hosts.

When Wiring ESX host to the Network and Storage. I wonder if we can do redundancy, for instance to Connect ESX host to 2 separate Network Switches and to 2 separate Storage Switches, which means the ESX will have 4 Nic Cards at least.
This is just my guessing, I am not sure if this is how they wire ESX hosts in Vmware Environments.


Thank you

Are we connecting to Network Storage ? e.g. iSCSI or NFS

Yes you can connect like that, and then setup Multipath and bindings as per my EE Article, if compatible with your Storage

Will NFS be configured the same way as you did for ISCSI ?

Another question came up to my mind. Should the Management port Group IP  be the same as  IP address of ESX host ?

No NFS is not configured the same as iSCSI, no bindings are required, and it can support normal teaming.

Are you referring to Management Network VMKernel Portgroup ?

Correct

Normally the ESXi IP Address would be the Management Network VMKernel Portgroup Address.

or is one and the same, you got different ?

But remember, you can tag/select any VMKernel Interface to be a Mangement Interface, and all VMKernel Portgroup must have an IP Address.

Should the Management port Group IP  be the same as  IP address of ESX host ?

it is the same, otherwise you would not be able to manage it...

it's a bit like asking, how do I RDP to a Windows Server, what's it's "management" IP Address.

We just do not use the term Management IP Address on Windows.

e.g. you could have a completely separate network just for Management, which some organisations have... e.g. all there out of band traffic for management, remote management of network switches, printers, SANs, NAS, VOIP, ESXi hosts, Linux hosts, SSH, Telnet, all goes across a Management Network for security, so no one can access back doors.....from the made Production LAN, which just carries e.g. Windows Share Traffic, no RDP etc

A bit like you will find on some SANs, Network devices they have a Management Network Port only for - Management and Admin only!
