VMware NSX Overview

[@freebk161]

This is a fantastic video explaining why and how NSX is evolved which gives us deep insight into the virtual network technology unlike others jump right into NSX. Moreover, the casual and informal way to explain with 'writing on a whiteboard' is very much appreciated instead of going over PPT's , just like a friend going over the new things over a beer !!! Keep up the good work. Your video is published in 2016. But I am learning it now because I am leveraging NSX in our product. Subscribing now... Thank a bunch Rob !!!

[@RobRikerTechChannel]

Thank you! Glad you found it useful!

[@markrobson7444]

Thanks Rob, I continuously come back to this video to refresh my NSX skills. Great vid ;-)

[@thomaspinto8964]

Well explained. Helps a person with little to basic network understanding. Thank you Rob!

[@ppvshenoy]

Thanks for taking the trouble in explaining NSX functions well - the nuts & bolts. Much appreciated.

[@rajdhingra00]

It was indeed informative on high level. Please cover the traffic patterns seen in real world to understand the use cases like bare metal to virtual, role of ESG, where does the ESG sits i.e. one on each host or somewhere on a central server, how to size the servers hosting the DLRs, ESGs, NSX Manager etc. how to use & integrate the external L4 to L7 services... How do we do IP addressing, is it done manually or dynamically... There are lot of questions going over my head right now. Thanks

[@cmatthews718]

This was extremely helpful and well explained. I jumped around to different sites and documents and still had a hard time making this click in my head, but now I get it after watching this video. Thanks!

[@EoeSantinny]

Best explanation I've seen so far for NSX integration with current infrastructure. Felt all the other videos didn't convey the idea of how NSX ties in to your current infrastructure. Job well done! NSX starting to make a lot of sense now! thank you!

[@RobRikerTechChannel]

Thanks EoeSantinny, I appreciate that!

[@aquabat104]

best nsx explanation on youtube

[@nihalmaharana3762]

Thanks Rob for this great overview of NSX

[@srinraoa27]

Thanks a lot Rob for Excellent presentation and explanation. 👍

[@alitquanmallick5241]

Wow this is a brilliant video. Excellent diagrams and examples.

[@uv777gr]

Needed this today, thanks for the 101, subscribed!

[@ace260374]

Fantastic explanation of how NSX works :) appreciate that !!

[@windyruss]

Great explanation. Easy to follow and well explained plus contains the words of wisdom "Well, sorry for ya, but you gotta fix your crap.."

[@RobRikerTechChannel]

Thank you!

[@hareessh100]

Good Job..helped me understand the overall picture as to how NSX plays..

[@vishalreddy3975]

Good overview rob. Hope to see more nsx stuff from your channel.

[@DavixXx972]

Dude your video was a blow of fresh air into my brain.

[@hazorli]

very interesting.The claim in 27:15 is not true, you have a lot of vendors doing overlay with VxLAN in the hypervisor. you actually can do it with opensource like openstack and ovs + SDN controller to setup vxlan tunnels from the virtual switch.

[@Calphool222]

Yeah, overlay networking is entirely independent of vendors. You can literally run flannel on bare metal if you want.

[@veereshsurwar6977]

Interesting one Rob...Thank you for detailed explanation.

[@lpon9757]

Really nice perspective, looks like it makes it really 'easy' to manage what should be a nightmare otherwise

[@iqbaldotme]

Thanks for sharing this! very informative!

[@munnaaug502]

Excellent explanation on NSX. Thanks

[@netzstriker]

Hey Rob thanks for the high level overview. In our small nexus, esxi, ucs environment we will be rolling out vxlan, probably next year, as a possible fit for inter datacenter vm motion. . NSX, is something we will be looking as well too. Thanks for the high level , good for me to start getting my feat wet now.

[@gagankumarsharma]

Thank you very much. Now I have the basics of virtual networks

[@friday6426]

I watched your video today to learn about VMware NSX. It is a good high level view. Thanks for your teaching. I am assuming N2K TOR, N5K EOR, N7K L3 are all physical switches, right? But I'm not familiar with those types of switches. Which vendor is providing those kinds of products? When you scale the network, do you scale N2K, N5K and N7K simultaneously, or you can scale N2K, and if needed, then scale N5K, then last, scale N7K? I'm guessing N7K is much more expensive then N5K and N2K.

[@bitwrecked]

Very well done! I have watched this a few times and each time I got something else out of it. I assume this will be the case the next time I view it (in a few months).... Keep up the great work!

[@RobRikerTechChannel]

Awesome! glad it helped out

[@SachinSharma7]

Good work Rob. Thanks for making this.

[@lynleyagsam4636]

Bar far, the best video for NSX.

[@RobRikerTechChannel]

Thanks! Glad you liked it!

[@lynleyagsam4636]

Ron, do you have another video on how to bridge between exiting vlans to vxlan? We are migrating from our existing cluster to a new cluster with NSX. Once again, thank you for sharing this video.

[@saurav0110]

very nice study for people like me who needs to learn concept in less time...

[@zackscaringello313]

TOR= Top of Rack. EOR= End of Row. You had them flipped and referred to them as Top of Row and End of Rack.

[@amaruzunovic3126]

Tnx for the perfect presentation..

[@rickmcgee9262]

Really liked your video thanks for sharing. Nice CCIE plague in the background.

[@ManjariRajashree]

thnk u so much for making thiz video.very much helpful for understanding nsx concept.

[@lunhamegenogueira1969]

Am a bit late for the party, but thanks for the overview, very enlighting.

[@MustafaAli-mn2ko]

awesome Video, really appreciate the way you explain

[@nesmarey]

Amazing Video, Thank so much, it is quite clear; and I like you deployment perspective that you use during the whole explanation

[@RobRikerTechChannel]

Cool, glad you liked it.

[@j_r0dusmc168]

Question: the “controller VM” u mentioned that would link between the DLR’s and the Physical L3 GW’s, wouldn’t that be the ESG?

[@RobRikerTechChannel]

It's the control plane VM of the ESG, but not the ESG itself.

[@vkankata79]

great video Rob

[@LewisBowerbank]

Thanks for covering this

[@robertperez7647]

Nice explanation. Thank you very much!

[@srikanthvoleti2588]

Hi Rob, thank you for the video. Could you please make a video elaborating the details on the traffic flows by quoting more examples, which could really help us.

[@PRPravee]

Very Nicely explained

[@stavrospineios3800]

Nicely done mate...

[@zeeshanmahmood8627]

good stuff mate, learnt a fair bit

[@mk12347]

very well explained, got one question. when you use NSX and you create virtual VLANs on several hosts, can vms on different vlans talk to each other if virtual routing is enabled without the need to add thoses VLANs on the physical switches OR any virtual vlan created on vmware should exist on physical switches?

[@RobRikerTechChannel]

The whole point of VXLAN is for the hosts to have several VLANs created and for the physical infrastructure to not have to learn about the VM environment. If a VM on host A wants to talk to a VM on host B and they are not in the same VLAN, DLRs and logical switches could be used to make that happen.

[@adrianbosshard3371]

well done explained, thanks men!

[@truesaeedco]

Thanks Rob, Great Job

[@Niche_skills]

The host seems to be connected to a single TOR switch, This way the switch will become a single point of failure. there should have been two TORs and host should be getting a link from each one of those for better redundancy. Correct me if I am wrong..?

[@sreenislg]

Awesome video....

[@alexdanke133]

Great video man!

[@nuruddinbohari5769]

Great job!, thank you.

[@247jokes8]

Very good Thank you

[@Mcephin]

Thanks, this is super helpful :)

[@mikrobinamtv1]

You don't need Enterprise+ licence for VmWare to have NSX. The distributed switch "comes" with the NSX.

[@georgiangelov9036]

Quality!

[@Ayahuaska8]

Thank you!!

[@noobsniperxx]

So this is basically VMWare’s version of ACI?

[@RobRikerTechChannel]

This is NSX V, which is end of support/life, so NSX T is the next generation. They are similar, but not the same. Once you learn one, they definitely correlate quite well.

[@torprodwit]

Thanks!

[@thereturnofcobra]

thank you

[@HARI420000]

How to get the VM details from NSX ?

[@RobRikerTechChannel]

not sure what your asking

[@HARI420000]

@@RobRikerTechChannel let's say we have PA VM 300 configured along with NSX inside a vcenter. Do we have any API or CLI which can give us that VM details from NSX env.

[@whummer98]

Based on your need for segmentation, there is a better solution and would actually do what NSX is doing but at the hardware level. It would then reduce the complexity of the VMware network design as well. TZ's are not considered any more secure than a VLAN and that is from VMware. They are not considered secure enough in truly secure environments.

[@RobRikerTechChannel]

Never heard of TZs. The NSX nodes deployed are deployed at the kernel level, which is effectively the hardware level. The design is a bit tricky to get but is well documented and deployed.

[@whummer98]

@@RobRikerTechChannel Sorry, TZ is short for transport zone. Even at that level it is not considered secure. In any case, there are far better ways to solve this issue via implementing open standards. You could even layer NSX in multicast over routed networks with NSX in multicast mode only. No need for controller nodes then. The only benefit would be routing happening at the host level. Also, what I meant at the hardware level is the switch hardware level.

[@srikandiduduk]

Does NSX same as neutron in openstack ?

[@RobRikerTechChannel]

srikandiduduk it appears to be an equivalent, dont much about the technology but they appear similar

[@siggyfpv5625]

Thanks man, that is simply awesome! Very educational indeed;-)

[@TamerAlzambely]

Excellent video , however VXLAN can be explained in a better way ,,i think Thanks

[@ashlord8190]

Top of Rack and End of Row isn't it?

[@ashlord8190]

just saw other comments mentioning the same.

[@ussamabarakat4258]

too much of repeated sentences, this video can be only 20 min

[@Ramipineappl3]

you are talking extra waste few of my minutes still good.

[@pavankalyanvskp123]

worst

[@RobRikerTechChannel]

Pavan kalyan care to be more specific?

[@garlandcurley6376]

Good explanation

[@maparo1313]

Very Good done!
