Device to convert 2 port link aggregation to 1 port?


Recommended Posts

Hey guys,

 

A quick one. I have two NAS devices. My first NAS has 2x 1Gb ports that I would like to setup in link aggregation to improve throughput a little. My second NAS has 2x 10Gb ports but I would like to utilise only one of the 10Gb ports. Is there a device that will essentially convert a 2x 1Gb port link aggregation setup and then send it down just the one cable to the 10Gb Port. I have done a lovely paint illustration to explain a little better. 3e69776a06ee.jpg

 

 

 

Thanks in advance !

You would need a switch that supports it and also for the NAS itself to support it as well.

 

Are you just looking to improve throughput during backups form one NAS to another?

 

Is NAS1 or NAS2 the main one?

 

 

 

I would personally prefer to have the two separate 1 Gb links, one for access to the NAS from computers, then the other direct to the backup NAS.

 

So I would likely have a triangle arrangement where both NAS's have a line to your main switch/router for management access but NAS2 would be set up where you only have read-only access on that link, not sure what level of configuration you might have in that sense.

 

Then on the direct link between the NAS's (static IP and gateway) the NAS1 would have Write/Read access to NAS2 to backup without affecting traffic to either NAS from the main network link.

Hey bud.

 

My main NAS is NAS 2. NAS 1 is my backup.

 

The main purpose of the plan was simply to increase throughout when NAS 2 starts its sync job to NAS 1.

 

It looks like it would make more sense just to get a small switch which supports link aggregation to get this job done.

 

As the link aggregation enabled switch will be linked up with my main switch, NAS 1 will still get internet access and by extension management access. So unless I am missing something a link aggregation enabled switch will do the trick ?

Ah okay, so NAS 2 has two 10 Gigabit links both to your main network, one for network access, the other to NAS 1 replication?

 

In that case, yeah, you would just need a switch in between the NAS's that supports link aggregation the same as the NAS 1, but since it would connect to your main network, can probably just do a single switch for the all 4 connections (2 from each NAS). Here is a decent /r/homelab Reddit thread: https://www.reddit.com/r/homelab/com...k_aggregation/ that has some options.

 

 

I haven't looked in to that much, but from what I remember about my research in to aggregation on my UnRaid server was that having multiple 1 Gigabit links didn't increase throughput to a single client, only allow more connections at a time. So for NAS 2 to have increased throughput (over 1 Gigabit) to NAS 1, you would have to have to separate connections/transfers but even then they might still try to use the same link and only get 1 Gigabit speeds.

 

Personally I just setup multiple NIC's with different Static IP's and kind of map different appliances to different IP's. For example, my secondary UnRaid box has a Quad Intel NIC in it:

- Nic #1: Management/RDP/VNC

- Nic #2: Connections from within VM's for file transfers/download

- Nic #3: Plex and Web Services (external access)

- Nic #4: Network wide file access

Great thanks for confirming ! I thought that was the case. Thanks for sharing your NIC setup as well, gives me some good ideas. Now to just find an affordable 10Gb Switch with approx 8 ports that support link aggregation. Any thoughts ?

Just saw this, what do you think ?

Will see if I can find something cheaper but looks like that would do the job right off the bat.

Honestly haven't looked in to switches other than the Unifi ones I have that support it, but looking at the specs, that switch seems to check all the boxes you want. The dual SFP+ ports are nice for using fibre to get to other switches if you have long distance to get to.

Nice thanks, I looked at it and it certainly seemed to check the boxes ! Will make this one a future upgrade
