- In this video, we'll show you the easiest way to deploy Cisco's Official Virtual DNAC in your ESXi environment!
!!!!!!!!!! JUST 32vCPUs and 256 GB RAM !!!!!!!!!!!!!!!!
If you're looking for an easy and affordable way to deploy Cisco's Official Virtual DNAC in your ESXi environment, then this video is for you! We'll show you how to install the Cisco Official Virtual DNAC agent on your VMware ESXi server, and then configure it for use with your network. This video is easy to follow, and will help you get started with Cisco's Official Virtual DNAC in your environment!
In this video I will demonstrate how to deploy the Official Cisco Virtual DNA Center OVA in VMware ESXi. This image is rumored to be release in July and is the smallest footprint I have ever seen for the DNA Center appliance, but it is an official virtual image built for private cloud environments. This software release will make deploying a DNAC in an CCIE home lab or private sandbox much more affordable than it has ever been.
This is fantastic news! I honestly believed this wouldn't happen. Hats off to Cisco for following through ! I can't wait to deploy this in my CCIE EI lab. As always, thank you for being out in front with your work, Terry.
I felt the same way.
Amazing! Looking forward for the next video Terry! Thanks!
The OVA is now available from Cisco Software, thanks for putting this video together
Thank you for your deployment demo and for the News
Hi Terry,
I really appreciate what you do in this youtube comunity to explain some stuff as easier as possible to all understand and take their own steps to create home labs.
I would like to know if in some occasion will you show how to build it from beginning I mean Esxi > Server > vDNAC. >
I've been doing some test and study Esxi that I`ve never worked with.
Regards.
Sure David. I have wanted to do that for sometime.
Terry, thanks for making these videos. Does SDGeeks have a rack rental offering? I'm in need of hands-on practice with the latest versions of SDx that are present on the EI exam. At this time, I'm not convinced building my own server(s) is the best path forward financially. If SDG has rack rentals can you describe a bit how it works i.e. is scheduling require? How much "free reign" do students have within the lab? How long are sessions? Extra cost on top of membership etc? Any insights greatly appreciated!
Terry - Where does one acquire the OVA for this? I've looked through Software Center and have come up empty. Curious if you could provide some guidance on that. Let me know when you get a chance and thanks for all of your content! My friend Tim is a super fan and thankfully he pointed me toward all of your videos. Great stuff!
As I know for now you should support subscription (for 3 years) and now the name of it - Catalyst center
Hi Terry, thank you soo much for this amazing tutorial. Quick question, I'm building a new PC for my CCIE Lab and wanted to ask you if the 32-core AMD Threadripper 7975WX CPU with 512gb RAM would be sufficient to handle DNAC+ISE altogether? And a server isn't an option for me because of how noisy it is.
What kind of server hardware is needed to run a virtual instance of Cisco DNA Center?
Finally... thanks for the video
You are most welcome 🤗
Hi Terry,I t would be good if you could share the hardware configuration of your server hosting all these VMs...
Hello Terry, thank you for your fantastic explanation. Is there a date available for when Cisco will release a free VM version of Cisco DNAC?
No clue honestly. I made the video understanding that the image would be released in July-August time frame. Still nothing and its almost November. I have give up guessing, and just check daily. :(
Thanks a lot for sharing this kind of video.
I have some doubts about building my own lab... and I don`t know if you could help me with it.... or someone from the community.
Does server need 256 GbRam to install DNAC from beginning ??
Does server need 256 GbRam to run DNAC for lab purpose ??, I mean if I have less Ram it wont work.
Do you recommend installing SSD SATA 6GBPS or SSD SAS 12GBPS ??
Is there any DNAC Lite Version to install and practice ??
Regards,
To run the dnac you will need 256 GRAM if you want it to be stable and useable.I recommend using SSD with the fastest speed you can afford I use 12GPBS at 6TB total, but you don't need that much 1TB is enough for my unofficial virtual dnac install.
Hi Terry, thank you for providing such inspiration to the network engineering community. You've definitely inspired me for sure! I currently got couple of questions to run by you. (1) In this video, the VM settings have 3 HDDs (HDD1 - 100GB, HDD2 - 550GB, and HDD3 - 2350GB) but from your other video named "Building a "Virtual" DNAC for my Budget Centric CCIE EI Home Lab (Part 1)" there was only 1HDD only requiring 600GB SSD, so i just want to confirm whether 1HDD will suffice or it must be 3x HDD as specified here? (2) I'm looking towards purchasing a server with the following specs: [Dell PowerEdge R820 Server 3.30Ghz 32-Core 512GB 2x 500GB SSD + 2x 1.2TB 10K SAS 2.5" 6G]. Do you think these specs will have no problems to run the vDNAC home lab? I'm just concerned whether the storage component will be an issue since from reading a lot of the comments that having SSD is quite important but for my specs it will only provide 1TB SSD (whereas in this video the 3x HDDs combined has a total of 3TB). Your feedback is most appreciated and or if others can answer this then that would be fabulous also. Many Thanks!
good question, I am confused too. @Terry could you please answer?
They are two completely different things. The ISO installation from my budget homelab videos requires that volume one of the 3 volumes the system sets up is SSD. I just setup a single drive at 600GB "thin provisioned" and let the install wizard carve it up. The ova for the official DNAC is different. It will make 3 discreet volumes of the specified sizes you mentioned. I was experimenting with making it smaller and more "scaled down" but Cisco has failed to release the software like they planned so I have backed off, until such time there is an official release. Till then I am using both images. I actually prefer my ISO install on VMware to the official vDNAC. But 62 verses 32 vCPU is hard to walk away from. :D
Question, design workflow used in DNA is it greenfield or brownfield deployment ?
I have installed dnac-v2.3.7.5 as per your instructions but I cannot access it via GUI.
Can you guide me please
hi mr.terry , this tutorial was superb, thanks, how to get ova file of dna ?
I’m sure it will be posted software.cisco.com when they release it.
thank you so much !
hi what is the minimum hardware specs / requirement
can you share to us your server brand and model and harddisk - can i use SSDs only and not SSD?
planning to get this specs
dell PowerEdge R820 Server 3.30Ghz 36core / 654 thread 256gb ram 4x 600GB SSD + 2 x 300g - total of 3tb
thx
Would be awesome if it worked with an AMD 5950X with 128gb. Would be an affordable upgrade for people that already have AM4 setup without having to resort to the big server setups.
From your keyboard to God's ears.
Can you elaborate on the vmware network configuration and how it connects to your core...for example you set vnic0 to "dnacpg" is that a dummy vlan for the cluster link? Is it on a separate vSwitch?
I'll make a video on how I did it, but in a nutshell the "dnacpg" is a port group that is common between the DNAC and all devices in the shared services block (ISE, DNS, DHCP & IPAM). I am constantly trying to squeeze this into a single server because budget is king in building a home lab.
Excellent video ! "just" 256GB RAM, better beef up my server :-)
Well that's compared to 384GB RAM, but i have good news I am tweaking a second image and right now I have it working in 16 vCPU and 128 GB RAM. I want to put it through a Mock Lab to see how it performs. I'll make a video on that.
@@TerryVinsonCCIEx2 Lovely, looking forward to it !!
@@TerryVinsonCCIEx2 , that would be incredible if you get that working...
@@TerryVinsonCCIEx2 any luck with the mock lab with smaller resources?
@@Armurp01 sadly not at this time.
From where we can get the ova file ?
Hey Terry, Do we have a date to look out for this to be released?
Honestly no I don’t. Wish I did.
@@TerryVinsonCCIEx2 Thanks for the reply! Can't wait :)
I spoke with a Cisco rep and they've said it's currently planned for release sometime around August. Only way to get your hands on a copy at the moment is your company request a test copy which has to be used for testing only and non production.
@@Inkmice I was told sometime in July. So I guess sometime around August is a better way of saying it.
EFT in July/Aug, GA by end of CY. Reach out to your AT for EFT signup.
Does this vDNAC require 32 physical cores or 32 vCPUs?
Does the 32 vCPU and 256GB ram need to be dedicated or can it handle a little over-provisioning?
I'm thinking likewise to run vDNAC on the same host as my current EVE-PRO but I'll need to start swapping 16gb sticks for 32gb sticks to exceed 256GB ram.
Yes pretty much dedicated if you want it to be stable. I have tried to lower the specs with disastrous results.
@@TerryVinsonCCIEx2 Great thanks for letting me know. Time to buy more RAM then 😄
Why only 32 CPUv's? you had another video where minimum was 64, and anything less would led the dnac to become unstable?
Because it’s a purpose built ova optimized to use that foot print.
Do you think this will be possible to run in VMWare Workstation? I have everything else able to run in there (Except Prime which runs in my virtualised ESXi host). I've got an 8 core AMD processor with 64GB ram (Could upgrade to 128GB).
I very much doubt it; You've got 25% of the required CPU Cores and memory specified here as the minimum.
no.
Hi Terry, i am facing issue with ESXI DNAC or ISO file DNAC in Dell T7910 server, after successful installed, i am able to login and configure but once power down and power UP again DNAC services not starting, i waited for 2 hours but no luck. even though i am able to access via CLI. GUI not working even its shows ram incrementing very slow or some time its stop increasing. in normal scenarios, i observed if ram utilization reach 140GB then only GUI works, but in my case its stuck on 90GB and cpu utilization 40Gig Plus plus. please help me and guide me if i am missing anything.
What resources did you make available? ISO needs 64 vCPU and 256 GB RAM. OVA needs 32 vCPU and 256 GB RAM.
@@TerryVinsonCCIEx2 for ISO, i assigned 66 vcpu, ram 256, nvme ssd 3x 1.4 tb and for ova as per guideline. on both scenarios, same issue. i am using E5 2699 v3 x 2 CPU and 352 GB ddr4 ram
hi Terry, I install ova file like you but I have 64GB ram. after installation I am logging to web GUI via enterprise port. But I dont see anything expect the 3 menues. What is the minimum ram or CPU requirement for deployment. its only test deployment.
another quesiton is if my disk drive is not SSD, is it possible to install DNA to this server?
hi can please provide your email need some help for installation
i have never had much luck trying to lower those specs. It makes the image unstable and very slow.
The official vDNAC does not require SSD, just the ISO installed on VMware does for the first partition, but my baseline server build has 6TB SSD in a RAID. That's my standard not a cisco requirement.
I had a problem after installing OVA, error message "We encountered an error while attempting to upgrade the software." I can't download anything in Software management, error message is "System installed release not in stable state,Please make sure installed release is in deployed state and then retry again". do you know why??
hi peter , i need your help can we connect ?
@@mustafasayyad8089 Sure! How can we connect??
I have never had that problem. Did you get it solved?
Can we add DNAC in CML ?
No. It is to big.
how to get the DNAC-SW-2.3.7.ova which is OVA file?
When Cisco Released the software it will be available at software.cisco.com.
The updated time of release is around August.
@@TerryVinsonCCIEx2 can you able to share the software?
@@TerryVinsonCCIEx2 Any news on the release on CCO. I can't see it yet!
@@johnsmith44573 nothing at all.
@@TerryVinsonCCIEx2 Nothing from our Cisco SE either. Wonder if it's got issues, or due to rebranding to "Catalyst Center"?
