This is the kind of content we've been looking for from your new venture. Please keep up this kind of stuff.
Thank you so much for this video. I had tried a ton of stuff with SMB and for some reason I was getting either no results or wonky results. The content that you and Level 1 are producing is top notch and I am really excited to see your future
Thanks for the video, Wendell. I appreciate the ability to break down the subject you're speaking about into layman's terms.
Thank you so much for making this video. I have been having trouble with SMB for a long time.
KZread needs more videos on network like this, thanks for the work.
Thank you for these videos, Wendell! II'm a developer at an MSSP Company, but I also touch a lot of network and Linux system troubleshooting and maintenance, and I LOVE to learn new things. Your channel provides me with the knowledge I wouldn't get anywhere else. Thank you! As a special request, I would love to see more content about Linux advanced functionalities, processes, commands, troubleshooting techniques, etc etc. :)
Thanks for actually going into detail on this. Not many do. If I had any PCIe lanes left, I'd totally throw a big card in my rig, but for now I'm stuck. :)

Thanks for producing all the content that you do, this was very interesting.
More of this (networking in general), awesome stuff, thank you! Love the great tips in this.
Network stuff is like Japanese to me but watching videos like this is helping me learn a lil bit.

Like all things (including learning languages) it is all about immersing yourself. Work at it and learn about new things every day and eventually it will all start to 'click'. Keep going and you'll soon realise you know way more than you think!
I don't care about SMB or Windows networking but this confirmed my intuitions about dhcp and lan dns and I'm glad I listened.
oh my god this is a huge rabbit hole. good on ya for going through all of this
This video is SUPER important for modern nerds. Thank you so much. This information is very hard to come by.
This was pure gold even though I'm a Linux user, I sincerely hope you'll keep your eyes on the Linux side of this.

M Hagentoft on Linux if you bond the NICs, then it just works with things like NFS. Depending on the load, this can be a minor to a huge throughput difference. I don't touch Windows, so not sure how filesharing can be best handled as an NFS client is hard to find. In case you cared :)

I agree. Setting Plex and PlexPy up on FreeNAS 9.10 is still super easy, but once 10 hits in a month or two you will have a superior GUI and docker abilities.

I just set up my FreeNAS with Plex, did it successfully, I just found that their old video while good was very outdated, it would have been very helpful to have an updated one but if 10 will bring such large changes then waiting for 10 is probably the best bet.

Right now I'm running FreeNAS in ESXi (with the SAS controller passed through) and then a separate Fedora server that just hosts docker containers. As soon as FreeNAS 10 comes out I'm going to run it bare metal because it honestly will do everything that ESXi is doing for me now. I'm really excited for it. I also love the hell out of docker.
Wendell you are THE man, Logan played on your ubernerd to get a more technical side to Tek Syndicate that is now gone and leaving the Crit tv channel LACKING in so many ways! I hope you have abundant growth of you channel over the many years to came!!!

Great video, thank you so much. I had a supermicro board with both i217 and i210 and disabling RSS on the i210 worked great for me.
Hi Level1 guys. Just watching your video with Linus and I heard you talking about this one. Love love love the content you guys put out. Just thought I would post here letting you know that I have a casual interest in SMB multichannel. Well, to be fair, I think I just love nerding out on all of this stuff. You guys do a great job of taking an esoteric subject and making it very approachable. Am I going to go implement anything like this? Actually, I just may. Didn't think I would, but these videos make it look really cool. Thanks again for the awesome content!
it's awesome you did a video about this. I just got an ASRock fatality pro i7 x99 and I've been wanting to mess around with the dual NIC. so far in my testing I like how the 211AT NIC seems to perform, but the other one is a 218. I'll watch this again. I've known about MSI, but I never connected the dots between MSI and RSS. oh, I have a drobo 5n Nas but he isn't anything to do with this, I just like to mess around to learn. and since I have 3 computers plus a Nas and 4 phones and a printer in my network, network stuff is kinda fun.
Yo wendell I would be super happy if you could make a 101 video on networks and how networking protocols run... Like everything from the OSI model to TCP/IP and everything. I have been following you for years and your insight is super valuable to the community! Thank you for all your work :)

We've finally got a real tech channel on KZread
Thank you, thank you, thank you!!! Your troubleshooting guide is amazing, now it all makes sense :)
Absolutely awesome information!! You have earned my subscription.
Love all the details. I feel like replacing all my nics with 10GbE and just run with that on all my computers instead.
Fantastically informative video!
I got a FreeNAS box now thanks to you. I would love a video on some more of the advanced features of it.
Enjoy your vids, like the Surface on your desk ;). Just one nitpick, 1607 was "Redstone 1" (RS1), not a "Threshold" update (the last TH release was TH2, or 1511). Otherwise, good explanation of a somewhat complicated technology in accessible terms. Really great.
I did a review on that switch on the forums last year. Just search "confessions of a 10Gb newb" Thanks Wendell this is why we are here!!
oihh just thank you smb multichanel was such a headache ... you gave so much info! thank you!!!
First off, absolutely loved the video! I'm pretty new to all of this and have been on a hard-core path to learning as much as I can about FreeNAS and pFsense. I'm going to be doing a FreeNAS build in about a month or two. I'm so far planning on using a X11SSH--F from Supermicro. Do you for see any issues or limitations I may encounter with the 2 onboard gigabyte NIC's? I'm trying to maximize my throughput using some kind of link aggregation.
OMG! What an awesome opening line!
Love the channel.
You should include Amazon store links to the hardware you're using or recommend in each video. It's a great reference for curious viewers and a way for you to get a few kick backs.
You are awesome! Thank you! Love this stuff!
This is an awesome video. Even though I'm a Linux person, I loved the video.
Remember if you are managing servers and using SMB multi-channel you need to use SMB constraints to reserve one of the NIC's for management tasks. This ensures that you don't have degraded, over the network, control of your server due to link saturation.
very well explained
Wanting quad on my windows 10 pro machine and one on my freenas. Any tips on that. Getting quad ibm i340 for my freenas. Might just get another for my pc.
I can't find a dual or for that matter quad ethernet NICs for a low price. Would putting 2 or more NIC cards in my server work as well? Or do the interfaces need to be on the same NIC?
hey what happened to the peanut butter cup, on the martenee class?
another gooder. keep it up boys. and krista
awesome job
I'm curious, if you have multi-nic pc's, servers, and the patience to run a second layer of networking cabling to connect all the two. If you wouldn't fair better using the second physical network ( organized by subnet or vlan or ??? ) as a storage layer, and the primary layer for usual traffic ( more inline with the traditional fibre channel or iscsi topographies). Rather than ganging or bonding all the interfaces. If you were to do some high level network analytics.. is there that much benefit, ignoring all the teething pains you mention ?
Fantastic comrade.
I wonder if it will be possible to composite two NIC with different speed such as 1Gbps and 2.5Gbps to get 3.5Gbps speed.
Can i use this SMB MC on a Windows Server inside QEMU/LIBVIRT VM and 2 or 3 Nic in passthrough ?
Gday Do they have an opensource solution to replace Terminal server + Active directory so you can get the same thing but under Linux?BSD ?
Wow... I got a 802.11AD bond to a AC5300 which has support. I was wondering why NFS was going slower then CIFS, when the regular result is normally the inverse. Totally forgot about how they may be utilizing the bond.
I would love some more basics like that. I going to setup my first server config with around 50 windows computers for a small business and looking for some basic server hardware.
No idea how Logan has more subs than this guy. This guy was obviously the brains behind the success.
do you have any advice on how this would work on an amd based system versus just an intel system?
I have no idea what you are saying but I just like listening
You should do a video on FreeNAS in a mixed OSX/Windows/Linux with a single shared network drive.
Is SMB Multichannel, Microsofts attempt at Intel's Pro teaming function that you had an intel pro nic and a few other nics and used the teaming function to use 2-4 nics together
So there's no way to bring SMB 3.0 in Windows 7 Ultimate for my 2 gb/s LAG to work between my NAS and 2 other Win 7 machines even if it's set to LACP in the Intel NIC config page?
I work with Mikrotiks very frequently, and I, for one, would love to see review of that 24 port MT!!! *fingers crossed* :D
hahaahah oh man that opening made my freaking day, thanks wendell
*Very* damned informative, thanks!!
Hey Wendell have you tried running SMB multichannel while using LACP load balancing? It seems to boost speed for me, but only in one direction.

Thanks for the video,but personally im mixing linux and windows in my network so this will have to wait for me, however i have a strange bug/problem with samba in linux ; i have a server running ubuntu server, on my main pc i dualboot W7/Linux, when i copy files from or to my W7 install, i max GB, but when i copy linux to linux i get 30-40mb/s, same hardware same pcs just different OS, have you encountered this in your network Wendell ? (iPerf linux to linux says 950mb/s or so, so the nics can handle GB, the OS on main Pc is Ubuntu based, Linux Lite or Linux Mint mainly.)
I would love if you guys do a video about HSMM-MESH NET (the wifi of doom) since you cover all topics very well.
Hey, this was an awesome video so thanks for the input and referral to the forum. My team and I are currently dealing with an issue where SMB Multichannel RSS seems to break when a load balancer in Azure. One connection is seen via the load balancer however the other multichannel connections go directly to the real server. Ever heard of something like this? I will join the forum and post there too. Thank you for the insight 3 years later.
i need that aperture science handheld portal device.
What SR are you in OW?
Finally seeing some Mikrotik products. Use them at home, and alot at work(work at ISP). Works like a charm, and cheap AF. Do some mikrotik reviews and projects. Also check out mikrotik/routerboard wireless products. No so good for AP, but cheap and reliable PTP over long distances.
Good Information. :-)
Very good video. Definitely need a video on just RSS.
Hope Samba will get this soon too. Still trying to get hostnames working with my Linux router (currently using dhcpd and dnsmasq on Arch). 8:15 Well, my Networks all start with 10.0. (/16) and then have a few subnets from there.
Awesome way of improving network speeds without spending hundreds on 10gbe. Wish I had known about this when Windows 8 was released. Only set mine up last month.
what if you're using IPv6 autoconfig instead of a DHCP server?
Thanks! Turning off the RSS on the one adapter that supported it made the smb 3 work properly.
Finally, Mikrotik on Wendell's table :)
good video
Can we dump a multiport NIC in a PFsense router and use SMB? I would be very interested in a follow up video on that for people who want the extra network transfer speeds but don't have a NAS... like me :p
This cool, but my network is a mutt mix of OS's. lol Three on W10, fileserver on FreeNAS, pfSense, and some Arch for good measure. Plus random VM's I run to play with other stuff. I have found SMB to be a mixed back. I am using SMB to share a couple data sets to my network. One thing I have noticed is that if I try to delete files on the server from the over the SMB share on my main machine via windows, it's super slow to to the delete. But, if I go into the web UI and open the shell and do it, pretty quick. I am talking about a near 1tb folder. It can take a couple hours from the Win machine. But the CLI command is a few minutes at best. Not sure if it's an SMB issue or something else.
Will this work on an unmanaged switch.
Can i upgrade SMB port 1 to SMB port 3 in N2800.. if it is how
could a mixed windows linux enviroment be used in multichannel using nfs instead of cifs? or virtualization?

I don't think NFS supports multi-threading. Multichannel is a samba feature, not a network feature.

So if I smash one of those Intel I210-T1 cards off amazon into my system with onboard I211-AT, I should be fine? (I'll work on other decives on my network later, just want to make sure I'm on the right track first)
Mikrotiks/RouterOS are amaze been using mine for over a year now to manage my entire network awesome units and software, also does IPSec/PSK over L2TP server for nice little VPN server setup all on a the unit, so no more open ports to the internet :D! Setup up couple for clients and for a school to manage with opendns routing just for school computers and staff computers have limited to full access bypassing. there so much this units can do.

You can use any drives. The raid is on a different level, so any raid level will work. I don't think smb has a file size limit, but look at your filesystem.
Glad to see those goth dudes have left the channel. Keep up the good work!
16:29 workaround core affinity?
Bonding (linux, BSD), NIC Teaming (Windows Server), NIC Teaming (Intel and Broadcom drivers), LACP, Load balancing and failsafe modes - you should make whole video about these stuff.
How-To Desktop PC converts into a HOTSPOT System with voucher / ticketing system?

Its simply not fully implemented yet on opensource SMB.

Update video 2021 pleaseee so frustrating it is to co figure multichannel on Ubuntu. Works one way not the other, windows shows only two ports support rss
We want you on the WAN show!
I wouldnt mind an hour long video not even a two hour long as long as it had some actual instructions and useful explanations (also timestamps with the topics discussed wouldnt hurt :P )
forget going to college, i can come on youtube and just watch videos like this FOR FREE!
Would not mind multiple hour long videos on different aspects of networking.
