To Hanccoka: thanks for all your input on my questions! Would be great if you could give input on this question too.

Since the patch on my NAS (by Synology) solved a lot of problems, I tried again configuring my ISCSI's according your link:
http://www.experts-exchange.com/Software/VMWare/A_9250-HOW-TO-Add-an-iSCSI-Software-Adaptor-and-Create-an-iSCSI-Multipath-Network-in-VMware-vSphere-Hypervisor-ESXi-5-0.html

Now I see I have 2 things different then in your manual:
-when I want to bind the vmkernel iscsi network I also see the management vswitch (not in your screenshot)
-I added the dynamic links manually (added both ip addresses of my NAS x.x.x.x)

Furthermore I see events in my ESX (only one configured, in standby mode now):

Now, pracital questions:
------------------------
-please advise if you see any incosistencies in my config
-please advise if you would configure trunks (I will make vlans -new ticket I will create for migrating to vlans -bought a Sonicwall firewall-)

Note: for now (15 minutes) everything is working fine, however no vm's are running on it.

Thanks!
J.

Yes, in my article, I've setup a new vSwitch.

Check the number of paths to the NAS, there should be two paths per iSCSI LUN.

also you can login to ESXi via SSH or Console, and use ESX top, and check the traffic on the NICs, this is iSCSI traffic.

logs look normal and refer to local SATA devices (maybe) or it's a CDROM - mpx.vmhba1:C0:T1:L0
