DNA Center virtual

Hi

Is it possible to let the DNA Center run on hypervisors like Hyper-V or ESX?

Re: DNA Center virtual

As for today it is not possible to run DNA-C other than on the DNA appliance (DN1-HW-APL)

Re: DNA Center virtual

I've been told no - and I've railed about the stupidity of releasing a non-virtualized product in this day and age too.

Apparently some business unit that sells physical servers is still trying to stay relevant for another few months with the usual weak responses about "guaranteeing performance".

Please try again next year...

Re: DNA Center virtual

I attended an SDA seminar today at my local Cisco office and "guaranteeing performance" is definitely the battle cry. They are afraid that the customer will go cheap on the server resources making DNA Center perform poorly, or load up the server with contending apps, and then blame Cisco for all their troubles. I would not look for this to change anytime soon.

Just my two cents. Of course with inflation it's probably only worth .2 cents.

CCW tool doesn't recognize sku  DN1-HW-APL Does anyone know what is official sku from GPL?

Re: DNA Center virtual

I get that decision. I come from the partner ecosystem and have seen the management appliance for “competing vendor” installed virtually, with customers trying to get away with 16GB of RAM instead of 32GB, and attendant terrible performance. The very modest requirement of 32GB and 4 vCpu was a stretch for many of my customers.

 

By contrast, the smallest (and to date only) Cisco DNA Center hardware appliance sports 256GB of RAM, 44 cores/88 threads, and 8TB disk. Two 10GB interfaces and a couple gig, and yes it does need the 10GB bandwidth once it starts clustering.

 

In most environments, if you ask for those kind of compute and network IO specs from your virt team, you’re going to get laughed out of the room. That is essentially one entire host. Which is what Cisco DNA Center is: Under the hood, it’s Kubernetes containers all the way. 

 

I can’t speak to future product direction, but I do get what Cisco is doing here.

 

Edit: If you're unhappy about the price of the hardware appliance, talk to your partner about the FREE-DNAC-OFFER SKU. Still going as of the date I am posting this. If that doesn't fit you, try SDA-W-LABKIT (wired) or SDA-WW-LABKIT (wireless), those have additional discount on them.

Re: DNA Center virtual

Good luck with the adoption rate.  Until Cisco offers this as something other than a locked and loaded piece of hardware the adoption will remain low.  Not everyone needs 44 cores...  Or are you, with a straight face, going to tell me that this appliance configuration is required and will perform essentially the same for customers that have 10 or 1,000 or 10,000 devices?  Ludicrous is the first thing that comes to mind.

 

This is a virtual world Cisco.  The BU needs to get with the program corporate has been preaching. Even the bloatware known as ISE is available as a virtual appliance.  As a Cisco partner and enthusiast for decades I will not present this solution to my customers until the "one size fits all" mentality is gone.

Re: DNA Center virtual

Tchenry has hit the nail on the head.  It's hard to imagine that a customer with 10-20 switches is going to want a DNA appliance with the throughput of 44 cores and 256G of DRAM.  That's probably more than their entire compute platform put together!

The one thing I see over and over - and DNA Centre is another example of this - is the expectation that a customer will need to buy, design, build and maintain massive amounts of infrastructure in order to dip their toe in the water and try the technology out.  The product may well be very good but there's no way those smaller customers (and Cisco's idea of small is closer to my idea of medium-large) will ever spend the money to even take a look at it.  Some of those small customers become big customers one day too - start them on the food chain early on and then they will buy as they grow.

I'm also puzzled as to why Cisco doesn't release node-limited "Express Virtual" versions of this sort of software in order to get customers using it and interested in it.  The upgrade path is then to a full blown system after the customer has achieved some scale, has the money to spend and can see the benefits of using it.  This would also open the door to engineers like myself who can run the technology up, get some experience with it and then encourage our customers to buy it.

Re: DNA Center virtual

APIC for DC runs on virtual machine. Not able to digest the logic of not having virtual option as it was the case with APIC-EM. by restricting to hardware the option of hosting the DNA-C in a cloud is gone.

A new product like this could have made it look like a Gen X solution with a cloud option. The complementing component such as the ISE is still running on VM (or can).

get real by getting virtual :-)

Re: DNA Center virtual

Has there been any recent updates to this? Can we run on a 3rd party VM yet?

Cisco Employee

Re: DNA Center virtual

There is no update or roadmap information for the Cisco DNA Center Virtualization.  At this time, the Cisco DNA Center will only be supported on a hardware appliance.

Re: DNA Center virtual

Looks like it's possible to install DNA Center on VMware ESXI but as mentioned and stressed out in the video, "True horse power is needed" in terms of CPU & RAM

Re: DNA Center virtual

This is good info, thank you!  How do I order/obtain the DNAC ISO, is that something that can be ordered directly?

Cisco Employee

Re: DNA Center virtual

Hello,

 

Please observe that the linked YouTube video has not been published by Cisco. As of this moment (5/Feb/2019) Cisco does not support installation of DNA Centre as ESXi VM. The ISO is available only to customers that need to rebuild their physical Cisco DNA Center appliance. TAC will provide a special access URL to the ISO if during troubleshooting it is determined that a customer's Cisco DNA Center needs to be re-imaged.

 

Regarding a lab VM, it is well understood that there is a strong demand in the field for such a thing. If you require a lab VM then please open a dialogue with your sales team to discuss your requirements and possible immediate and future options.

 

Best regards, Jerome
