Forgot to say, love the channel as I've been reviewing a few things today. Very informative. Your sign off does make me chuckle a tad as I'm from England....

This is amazing, just followed your instructions and boom. fair play rexy nice one.

Been using smb multichannel with synology since 6.2 days and still works amazingly for me. With quad gigabit + sata ssds i've gotten speed tests in the 400MB/sec range (write consistency of that speed is highly dependent on the SSDs themselves but read speads tend to be consistent). I've even managed to get 1.5GB/sec with dual 10Gbe multichannel (again, sata ssd volume, 3 ssd's in SHR), two 10Gbe links on synology and two 10Gbe links on a windows client.

Would this still work without a switch? I have my 423+ plugged into my router, then the router running to my PC. Would it still work if I run another cable from the NAS to the router? or would I still need to run a 2nd network cable into my computer as well?

I have 2 Ethernet connections with different subnets. In order to take advantage of SMB multichannel I need to plug in 2 more Ethernet cables 1 to each subnet correct?

Thanks for this great video again ! Just tried with my DS920+ and my internet box switch (one 8 gbits link and four 1 gigabit links ). My Windows PC is connected to the 8 Gbits with a 10 gbits PCIe interface. Activating SMB multichannel works but i'm still stuck to 1 Gbits tranfert speed (113 MB / sec). Any idea ? Do i have to activate something in Windows ? Thanks again Edit : I found the solution, my 10 Gbits SFP+ network card wasn't compatible, i had to add my internal ethernet to the game, and now everything's ok. Synology : SMB3 Multichannel can be enabled if both the client and server have multiple network adapters. However, if you have a single network adapter, you can still enable multichannel as long as the adapter supports RSS. Note that if you use a single adapter without RSS, there is no difference in the SMB performance

I know this sounds like a dumb question I'm looking at getting our first nas the one I've been looking at looks like a pretty solid unit got 10 bays compatible with 18tb a piece for a total of 180 tb capacity it's got Four ports on the back Two 10 gig Two 2gig Mainly looking to store video files from our video production either 1080P or 4K and hopefully soon-to-be 8K video so very large files so this multi-stream application for us would be perfect

Sorry but im confused, didnt get how you were connecting your hardware. Is your NAS connected directly to your PC with two ethernet cables and in that case why? Im using a switch and am wondering now what the best choice for connecting it all would be.

As an FYI, the option for SMB Multichannel is not present in a DS418. My feeling is, what ever is not a + unit will not have the option.

❤🎉Tank You for another amazing feature explained. Combining this with other upgrades to speed up our outdated 920+ NASes You’ve mentioned (like2,5Gbps adapters etc) do You think it’s possible to expand 2LAN connections with extra lines created from USB ?? So theoretically we could output at least 3LAN “channels” from single NAS (with 1Gbps adapter)? Do You think this might work?? 🧐😅😅

I am using a Synology DS723+ with 2 cables plugged into my Router, so no switch. Those connections were set up as a link aggregation but, in an attempt to double my speed, I deleted the link aggregation and turned on SMB as per your instructions. Unfortunately, there was no overall speed difference and both of those still add up to about 120 MB/s with each of them fluctuating between 50 and 70 while adding up to a total of 120 MB/s. So it didn't seem to work in my case on a Windows 11 Pro machine. Do I need to turn on SMB on my computer like you did on your Mac?

It works fine on MacOS to my Synology connected to its 2.5Gbps USB interface which I added on previous before I tried multichannel.

Only one connection is being used, it ignores the other two. 3 x 1gb connected on 1813+, into a 2.5gb switch, which itself connects to a 10gb switch, then into my Mac Studio with a 10gb connection. Using `'smbutil multichannel -a", one server NIC is shown as "state connected", the other two as "state idle".

I'm going to guess the most common setup everyone has would be as follows. A PC with 1x 2.5Gbps port. A switch with multiple 1Gbps ports. Synology NAS with 2x 1Gbps ports. Im guessing there would be no increase to throughput in this scenario, because the PC is connected to the switch at 1Gbps (so would be better off setting up Link Aggregation). If the switch was upgraded to 2.5Gbps, then I assume SMB3 Multichannel would work and should see a throughput to the PC of 2Gbps (2x 1Gbps from the NAS)? I am also confused with Synology's documentation. The forum shows a picture with the client having 1x 2.5Gbps network card and NAS with 4x 1Gbps connections and states "When the client is using a single high-speed connection (10GbE) and the server is using multiple lower-speed network connections (1GbE) or the other way around". But on their Documentation/website it says "SMB3 Multichannel can be enabled if both the client and server have multiple network adapters"', so what is it? Do BOTH need to have 2 or more network cards for this to work?

take my views with a grain of salt but I'd say that 99% of "clients" have a single NIC card and therefore will not benefit from SMB multi-channel. by comparison, link aggregation's goal is not to benefit a single client but rather to split multiple clients across the NAS's multiple NICs. It's true that clients with multiple NICs will gain greater throughput when using Multichannel to a NAS but only if other clients aren't already saturating these links. For this reason, I think Multichannel is great for some use cases but in most SMB cases the benefits of Link Aggregation are still probably more appropriate.

Mr. SpaceRex, as always thanks for the FANTASTIC video. Can you clarify a few things? In your video you have TWO 1 GB Ethernet adapters on your MacBook. Does this work equally well when the Mac has ONE 2.5 GbE adapter [and Synology has two 1 GbE connections]? For instance, I have just gotten the $40 Anker A8316 PowerExpand USB-C to 2.5 Gbps Ethernet Adapter. And I would love to be able to double my speeds to my DS1813+. Would this work plug and play once the SMB Multi channel is enable on 1813+? Also, I have always thought that when you have MULTIPLE Ethernet connected to a NAS.. Let’s say a 10GbE and ALSO a 1 GBe [for WOL], that you would have to connect to NAS via the IP address of the 10 GbE connection? But, it seems in your video, I misunderstood and if I enter a CONNECT to server of smb:DS1821/Videos that it would AUTOMATICALLY pick the fastest connection. So, MacBook has WiFi and 2.5 GbE connections it will always connect via the FASTEST… automatically… Is that correct?

You have to have at least 2 NICs on each system*, and preferably the same number on each. For example, 3x 1Gbe NICs connected to 2x 1Gbe NICs actually reduces throughput to 1.5Gb total. * There is a potential boost to CPU core utilization if a system with 1 NIC which supports RSS is connected to a system with 2 NICs. However, this is relatively marginal, and does not increase throughput.

That can be a benefit if the server has 2x 1Gbe NICs, but would be simpler and faster to have 1x 2.5Gbe on both ends. RSS is only a benefit to CPU core utilization if connecting a system with 1x NIC to a system with 2x NICs. And in that case, it isn't actually providing multichannel across the link, only to the CPU of the system with 1x NIC

I don't like 2 (or more) ip x device however, there must be another way (maybe)

Would this help plex server ?

What would be GREAT is to find a Switch that supports 2.5gb & 10gb that has LACP and/or LAG for under $100, can't seem to find one for under 2.5x that... Probably should have just held out for the DS923 instead of my DS920.... grrrrr

Can someone please tell what is the first sentence he said? Can’t figure it out after watching so many of his videos.

its amazing but my machine (MacBook Pro) if go to sleep and wake up its back to one Chanel 120mb

I have a NAS with x2 Ethernet ports. On my PC Do I need to install x2 1GB ports on my PC? Or can I buy a Single 2.5GB port? You mention it’s not recommended for video editors. What about still RAW photos in Lightroom and Photoshop? Would this make it possible in theory to use something like a cheaper NAS such as a 220+ to edit photos directly from the NAS?

Yes on PC you will need to 2 x 1GB Nics , a 1 2.5Gbe will not help for the speed,

Your setup WILL work if you plug the 2x 1gbe ports into a switch that also has a 2.5 gbe switch!

Synology released a package update to SMB for DSM 7.1 users over the last couple of days. Installed via Package Manager. Installed it yesterday. I am limited to a single 25G connection to each of my two Synology NASes however, so I don't expect to see any difference.

I don't think you will see any differences, to See difference you need 25GB 2 Nics in Synology and 2 25GBe in Computer, In theory 50GBe you should get but most likely bottle neck will be the the DSM will not be fast enough or your computer not fast enough, Did you mean 25GB or was it 2.5GBe ? Different Discussion if this is the case

Yes! This was just a 1 GbE switch

this is awesome.

I think most peoples scenario is a 2.5 GbE or 5 GbE or 10 GbE nic on a computer connected to a switch of same speed (10/5/2.5/1 GbE) and a synology with 2 or 4 pcs 1GbE nic´s. connected to that same switch. I have 2 computers, one with a 2.5 GbE and one with 10 GbE nic. A 10/5/2.5/1 GbE switch (NETGEAR XS508M) . A DS1520+ SMB multichannel enabled and connected with nic 1 and nic 2. My speed only went up from 110 MB/s to 125 MB/s. I use cat6a and cat7 on quite short distances. Maybe the switch is not capable of handeling this, but its not impressive!

From my understanding your computers need to have 2 nic to be able to take advantage smb multichannel if you only have one NIC on your computers you'll only use one NIC on the NAS

I don't understand your remarks that contrast SMB multichannel to link aggregation by saying that the former somehow goes against networking standards, Rex. I don't see how these standards could possibly forbid a client from establishing simultaneous TCP connections to multiple IP addresses that just happen to be different interfaces on the same machine. (Or in fact, even to different IP addresses on the same physical machine-VM networking does this...)

For VM’s it’s totally fine because they are routed to a different host. It’s summed up in this forum post: www.truenas.com/community/resources/multiple-network-interfaces-on-a-single-subnet.45/

Just don’t edit from the NAS and you’re golden!

To bad slow file copy problems over SMB still exist in 22H2 Windows 11.

I have to disable Link Aggregation to enable SMB3 Multichannel. Now I feel bad. I bought a switch just to enable that link aggregation. Heh.

can you do it for me? i well pay
