iSCSI Cabling to uplink switches

Hi,

Thanks for your question.

It should work. Which model are you using? https://dell.to/3tKQatJ and https://dell.to/3RUvXd0 and https://dell.to/3RPVX9A may help.

Let us know if you have any additional questions.

Hi

In this scenarios

I am not sure how server on this diagram will be able to see  Storage Network 1 which is in LACP bond since it is not connected to it

Hi,

Thanks for your question.

The server will connect through the iscsi network and not the storage network in that example.

Let us know if you have any additional questions.

If i have 3 storage networks and 3 VLANs for example

Storage network 1 192.168.10.0/24

Storage Network 2 192.168.20.0/24

Storage Network 3 192.168.30.0/24

This server doesnt have path on iSCSI network to connect or somehow Powerstore does the routing

Storage Network 2 and 3 have full connectivity but storage network 1 I cannot see connection to that network

Port 0 is Storage network 1 Port 1 is storage network 2 but where would connection come to Storage Network 1

Why are you needing it to connect to storage network 1? Storage resources should be able to be reached from the other networks. You may want to do the networking procedures on solve SolVe (https://dell.to/4cbCYQ4) and https://dell.to/4cbCZU8

We will configure VMkernel with particular IP addresses so the kernel in esxi host has to connect to something

What I am basically connecting to.

In iscsi communication and it was for at least 15 years in ESXi if i have vmkernel for example 192.168.128.15/24 storage adapter will connect to this storage network and for a path

Unless something is different now

Can you point the vmkernal to storage network 2 and 3? https://dell.to/3wOJAng and https://dell.to/3PjoLH7 may help.

yes I can they connect directly 

from this diagram if i go via iscsi switch they connect

Storage Network 2 one subnet

Storage network 3 another subnet

Just wondering how to get to Storage network 1 where would be connection if storage network 1 is 3rd subnet

Since SN 1 is not directly attached I am not seeing a way to make it reachable. https://dell.to/3TxqgUr seems to indicate you only do 2 storage iscsi paths.

My proposition would be something like this to get 4 paths. I would like to avoid Port 0 and 1 on 4 port embedded card. Each NIC from the server has access to each Node to satisfy node affinity rule. This way I have 4 active I/O paths to each LUN

Try it and let's see if it works the way you want.
