VMWare ESXi MPIO vs
I post my comment/question under HOW TO: Add an iSCSI Software Adaptor article.
Reading here
under Basic Requirements it is suggested to not use to use MPIO or MC/S with Link Aggregation
I am wonder what is recommended to set up on physical switch instead?
I implemented configuration where both NIC for Synology NAS are set up via LACP ethernet channel, and switch is configured with LACP and ports are bundled in port-channel.
On the ESXi side I below configuration creating MPIO,
and on the switch I have two ports bundled in port-channel.
How do you recommend the switch setup for that?
(I have separate vlan isolated from other traffic only for data storage.)

Note: It is not recommended to use MPIO or MC/S with Link Aggregation Network Links, please select one method (MPIO or MC/S) or use Link Aggregation. Using both, while technically possible, is not practical, and involves complicated network setup.

So I should disable on the Catalyst
and change:
and using Synology NAS could I still use Link Aggregation with 2NIC so I will have one IP connection to the iSCSI Target, or it is recommended to set NIC separately? (if yes how than add iSCSI Target in ESXi?)
You have mentioned set Round Robin
http://forum.synology.com/ wiki/index .php/How_t o_use_iSCS I_Targets_ on_VMware_ ESXi_with_ Multipath_ I/O
I should probably follow STEP 9 from Mounting the iSCSI Target on the ESXi Hypervisor
and change:
interface GigabitEthernet1/0/3
description ESXi VM-STORAGE
switchport access vlan 50
switchport mode access
channel-group 5 mode on
interface GigabitEthernet2/0/3
description ESXi VM-STORAGE
switchport access vlan 50
switchport mode access
no channel-group 5 mode on
tointerface GigabitEthernet1/0/3
description ESXi-2A VM-STORAGE
switchport access vlan 50
switchport mode access
interface GigabitEthernet2/0/3
description ESXi-2A VM-STORAGE
switchport access vlan 50

How are your vswitches configured? That would have a a lot to do with how your switching is configured
ASKER
My vSwitch for Storage is configured as shown at the bottom of this post
One vSwitch with two VMKernel Ports that is associated with one NIC per VmKernel Port witch IP address associated to each.

MPIO by default uses more than one nic (ensure you configure round robin on the datastore)
