ReadyNAS Pro / 802.3ad teaming / Hash option / Smart Switch
Hi there,
I recently upgraded my ReadyNAS Pro Business Edition from RAIDiator v4.2.9 to RAIDiator v4.2.19
After an overall check of the new features, I see the "hash" option when we use a teaming configuration.
On the NAS, I use a 802.3ad LACP teaming. By default, the hash option is "Layer2", but we can select "Layer2+3" or "Layer 3+4"
I've read the documentation about the differences between all theses options, and I got a question.
In front of the NAS, I use a GS724TPS Smart switch. I've configured a LAG witch LACP to connect my NAS. This works well, but I don't have any option to select the corresponding Hashing method into my smart switch. (This seems to be available on layer3 manageable switches only)
My question is: What kind of hashing method should I use in the ReadyNAS as I can't select any of these method in my smart switch ?
From my point of vue, I've tested "Layer2" option and "Layer3+4" option, and both worked. Is there an option better than the other ?
Actually I use the "Layer3+4" option but I wonder if this is really the good choice ... my switch is a layer2 switch only ...
Thanks for your help

- I'd like an answer to this too. The documentation is vague.
I've recently purchased a NetGear GS110T in ordet to make sure it's ultimately compatible with the new ReadyNAS Pro6 and Pro4 we aquired.
I set up the ReadyNAS Pro to use 802.3ad and LACP teaming, with a hash option of layer 2, the default.
After a day the ReadyNAS Pro drops off the network and my Hyper-V and fileserver boxes go balls up.
Should we switch it to Layer 3+4 for the hash option? It looks to be required.
In the GS110T there is no way to set an associated hash option.
Please confirm. - There are some known network hanging issues with 4.2.19. Can you try the new 4.2.20 (http://www.readynas.com/RAIDiator_x86_4_2_20_Notes) firmware which should resolve this issue.
