ISCSI target from ESXi host LAN port

Hi there

I have an ESXi host with virtual machines on it, and the management network is on LAN port 1 on the physical server.

I wish to expand the storage by using an ISCSi initiator on a virtual machine, looking at a NAS device presented as an ISCSi target on LAN port 2.

How can I do network addressing and configuration on the ESXi host in order to achieve this successfully?

Thanks

BH

first, you can't present NAS as ISCSI, the NAS msut support iSCSI to do that, otherwise you will not be able to do that.
if it supports iSCSI, just load the iSCSI initiator that comes with the windows and connect to the iSCSI target.
from networking, create a new vSwitch and PG and tie it to NIC 2, no IP configuration needed on the ESXi NIC.

Sure - I'm aware the NAS needs to be iSCSI.

Thank you. What sort of network addressing should the new interface have in order not to mess up the existing NIC 1?

new subnet will be highly suggested.

there is no requirement to give your physical nic2, a IP Address.

But make sure your iSCSI NAS and VM, have a different IP Address range to your LAN

e.g. 10.10.1.x

So for example if the LAN is 192.168.0.x, what would be a good range for the VM and NAS? Would I need to use a crossover cable?

Yes, to directly link Server and NAS (with no switch) you will need a crossover cable, but you might want to try a standard cable, because some devices are now auto switching. (auto-crossover!)

192.168.1.x or 10.10.1.x
