[Solved] Lagg or bridge

#1

Post by ernie » 26 Jul 2015 15:32

Hello,
I have 2 rj45 port on my nas.

I would like to have more bandwidth.

I am noob and I don t know the difference between bridge and lagg (fast Ethernet channel).

Is there a difference of bandwidth or is it the same ?

What do you recommend me ?
I see only that lagg as also an option of failover.

And do I need to set up also the switch ? Or only the nas ?

Thanks for your help

a bridge is a device to separate one network into two collisiondomains (broadcasts from one dont go into the other)
a lagg is the bonding of 2 or more ethernet interfaces to one.

only lagg provides failover
and both the nas and the switch need to support and be set up to do it.
and it only improves the bandwidth for multiple clients.
with a single client you wont notice much improvement.

Thanks

What do you mean with multi client ?

Example: on my nas I have nas4free, one jail with owncloud, and 2 VM with phpvbox, and plex in full installation.
All these systems use the same port for the network. So if I use aggregated links for the 2 ports of my motherboard, I will have improvement, isn't it ?

if you have one server and one client you wont see much improvement.
you will need a lot of clients to take advantage of lagg.
