snapmirror and multiple path to increase transfer data rate

Hello,

I was reading about snapmirror and got a question that i would like to share with you all.

From the Online backup guide:

"Multiplexing mode—SnapMirror uses both paths at the same time, essentially load balancing the

transfers. If one path fails, the transfers occur on the remaining path. After the failed path is

repaired, the transfers resume using both paths."

So, for instance if I have a VLAN dedicated to transfer SM data from one filer to another, lets say VLAN 2, if I assign two IPs to each filer on the same vlan and use them in multiplexing mode on a SM replica, will the multiplexing mode increase the transfer to twice (kbps=2000 on each channel) kbps = 4000?

filer 1              filer 2

           VLAN 2

IP1  ---2kbps--- IP1

filer 1              filer 2

           VLAN 2

IP1  ---2kbps--  IP1

IP2  ---2kbps--- IP2 (configured as an alias on the same vif)

name=multi(filer1-vif0,filer2-vif0)(filer1-vif0_alias,filer2-vif0_alias)

On source and destination filers I have vif configured with LACP with switches supporting this config.

Thank you

Miguel

I have no direct experience with this but this link looks helpful: see pages 6-7
