- I've always quite frankly been almost annoyed by the complexity of data centers. There are various kinds or servers, different storage devices, switches, gateways, power and cooling, different types of cables and dozens of protocols....the list is endless. And don't even get me started with the management complexity!
All this just feels...overwhelming and wrong to me. There must be a better, an easier way. And my prayers have been answered! For a few years now, "hyperconvergence" has been disrupting the enterprise IT markets with it's extreme simplicity. Old-fashioned solutions are being challenged all over the enterprise world by a new breed of intelligent technologies like hyperconvergence. And I, for one, welcome the future with open arms!
Let me me explain what hyperconvergence is and why I think future of data centers is hyperconverged.
My previous video "Private Cloud Rules!":

My pleasure! Glad to hear you found it useful, Vishakha. 👍
Great presentation! simple, down to earth explanation which make sense! thank you
Thank you, mraperish! Appreciated.
Simple and excellent explanation. I've been in IT for 20 years and very old school, and all these explanations were annoying and overly marketed and I still didn't have any idea what HCI was. Thanks for that. PS. You look like a European DJ who should be fake mixing in Vegas for a million dollars per set =)
Thank you, Felix! Appreciated.
Hahaha! Thanks for the tip. I'll start warming up mixing moves for my next trip to Vegas. 😎🕺
Brilliant - 🙏 for your clear mind and teaching style :)
amazing explanation about HCI bro. Thanks a lot. I would like to watch more of your videos. Please do post.

Awesome! Keep talking about private cloud and HCI! 💪😎
Learning from this video I understand now that HCI is not for me and my customers (I'm an IT admin). Thank you for taking the time to explain.
My pleasure. Absolutely right, HCI is not for all use cases. Like is no other solution.
@@TechEnthusiastInc Agree. Also, just because its the latest tech doesn’t mean it’s “the best”. As I’m mastering the “old way” of 3Tier, I’ll just skip this development cycle. Thanks for sharing.
Excellent Demo and explanation. 👌
Thank you! 👏
Man you should establish an online course platform......a concept well explained and understood is foundation of any studies and you are really good at explaining things
Glad to hear, Inusah! Funny that you mention...we are actually currently developing online courses, it's called "Tech Enthusiast Academy" and have already developed the first experimental courses but it's not quite ready just yet. Keep following us here and in LinkedIn to stay updated! :)

Great presentation. Well done.
The whole HCI 'stack' is very much what SUN/IBM (Sun is intentional, Oracle lost their way) were doing for decades. Things like the old x4600 series kit with huge CPU/Memory allocations, 47 internal disks. Running LDOMs as the virtualization/hypervisor layer. All managed from the same interface (albeit CLI). Same hardware & software vendor so 'one throat to choke' when/if it went sideways...
We're doing the same thing now, just on x86 kit instead of SPARC/Power# (likely for less $$$ of course. Both IBM and SUN charge like a wounded bull!)
The wheel turns it seems....
Very interesting, thanks for that, Calin. Only few things are actually completely new in this world these days. Everything tends to be a reiteration or remarketing of something old. :)
Again Great Markus
Expecting to next level of videos .... Happy in learning
Awesome, Ranjith! Stand by for more soon! 😋
@@TechEnthusiastInc I will be going to work on this.... Could u please direct me from scratch ?
Also for HCI is there any certification available ?
What would you like to know, Ranjith?
There are quite a few vendor specific HCI certifications but I'm not aware of generic HCI certifications. If anyone knows of some, sharing is caring! 😊
@@TechEnthusiastInc ok... Could u plz list the vendor specific certification for HCI
Here's a few. But remember that they are not general HCI nor objective, they are their own HCI product certifications.

Superb explanation, thank you
Thank you, Gopi!
Well explained. The drawings were clean and awesome. Like about True Appliance concept. We have DELL EMC and Nutanix software - its real pain to deal with 2 vendors when ran into issues. Thanks! Subscribed.
Hi Beopa! Thanks for the comments. Yep, support is very, VERY important with business critical hardware like HCI. Mixing multiple vendors has a toll on support experience. Always. No matter how good vendors are alone.
Great video, thanks for making this
Thanks! My pleasure.
Very Insightful. Thanks a lot!
Thanks, Premkumar! 👍
thank you so much , I learn a lot that will prepare me to deploy nutanix in the company I work for
You are welcome, Mohamed! Awesome! Nutanix is one of the best HCI solutions out there. Good luck with the deployment. :)
Nutanix - $25-50K worth of clustered hardware for $55k- 110k!
Greatly explained👏👏👏
Thank you, Ronald! Appreciated. 💪
The drawing is so.. satisfying.
Thank you, Michael! That's the highest form of compliment to me. 😂
Awesome video, very well done. May I know what software/hardware tools you use to create those drawings. I've seen this before but don't know what it is.
Hi Aditya! Thank you. The method is called "lightboarding", you'll find a lot more information with that keyword. Basically it is a big thick LED-illuminated glass in front of me, then I film drawing on it from the other side and flip it horizontally in the post production.
Great Explanation.. Impressive
Thank you! 👍
excellent presentation!
Thank you, Amir! :)
So Clean .......Amazing !!!!
Nicely Explained !!
Thank you, Coco!
Another fantastic video x
Glad to hear you liked it!
Thank you very for this video I never seen anyone who is explain the topic like you. I want some videos on Hyper converse like Nutanix.
Great to hear, Amit! Hyperconvergence is one of my favourite topics and I will definitely try to make more videos of HCI in the future. Stay tuned and subscribed! ;)
best HCI video I have seen so far!
Thanks, eapradius! 👍
Hi Markus, very clear and informative video. Will you have a video talking about Scale Computing HCI solutions? Thanks a lot!
Thanks, Reno! Appreciated. I would definitely love to do something around Scale but at the moment I don't have any plans. Though, if they happen to send a demo kit my direction, a Scale Computing video will be coming ASAP. 😋 Thanks for the request. See you around!
Nice Explanation !
Thanks a lot, Balaji!
I watched all of your videos. Those ware fantastic. As a beginner is there any other way to learn more from you! That will be helpful for my carrer
Hi Ariful! Glad to hear you liked my videos. Thanks for asking, I am planning to add more content to the Tech Enthusiast Academy (academy.techenthusiast.com) when I have a bit of extra time. How do you like that format? And what topics would you like me to cover there?
This is a very great explainaison !! great job. And how do you write and film on the transparent whiteboard ?
Thank you, Siks! I am happy to hear you liked my video. :)
The method I use is "lightboarding". You will find lots of information from Google and CZcams with that keyword. Basically I add a big clear thick glass between me and the camera, install bright LED strips around the glass (illuminating into the glass) and write on the glass using neon markers.
Then, I flip the image horisontally in the post production to make the writing appear readable to the viewer. Makes me look left-handed, though, but that's a minor detail. ;)
@@TechEnthusiastInc Wow, you rock! Some people would rather give a cryptic answer. You are truly a Master on Training, as I just learnt how to pull that off with your explanation.

Hello Sir,
I hope this message finds you well, and I want to express my gratitude for the insightful video you shared. It's truly appreciated. May you continue to be blessed in your endeavors.
I have a question regarding your discussion on Hyperconverged Infrastructure (HCI). In an HCI environment, do we virtualize the memory and servers in the same way we do in traditional virtualization practices, or are these components simply compartmentalized into separate physical units within a different space?
Thank you for clarifying this for me.
Best regards,
Hi Murtadha! Thanks for the feedback. Glad to have you around!
Technically HCI is very comparable, even identical, to what hypervisors do. For example, you can create a technical HCI solution only with VMware software, namely vSphere, vSAN and VNX. Actually VMware offers a HCI software stack to be use with OEM server vendors (like Dell, HPE and Lenovo) in order to offer complete VMware HCI solutions. They call these vSAN ReadyNodes.
Where the difference to just server/storage virtualization come from is the way the whole hardware/software stack is managed and how warranty+support work. A true HCI solution is managed with a single user interface - you don't have to manage server, storage and networking separately from their own separate UIs. Also, the whole HCI node is under the same warranty and support contract. No need to call server, storage, network and software vendors separately in case of an issue.
Hope this helps.
Very well explained.
Thank you very much for the feedback, Jonny! Glad you liked it. :)
Good Work. SAN Switches also include into the network Layer
Yes, SAN switches are technically networking devices but topologically they are usually separated from LAN/ethernet networking because of their role to only support specific (storage) traffic. However, it is a bit blurry how SAN fabric should be illustrated with HCI since basically all HCI solutions still need some sort of "SAN" to connect the nodes as a cluster. Anyway, storage network is greatly simplified in HCI solutions compared to traditional SAN.
What I would LOVE to see from vendors is a complete fabricless design where nodes are direct connected together, only multi-cluster environments would need (low-bandwidth) networking. Technically - and especially with the help of technologies such as VMware NSX - this should be no problem.
You’re a born teacher.
Thank you very much, John! 💪
Great explanation tanks a lot
Thank you! My pleasure.
Fantastic explanation, keep up the good work
This is awesome. where do i begin from to implement HCI. What sofware can i buy. I have a few x86s
Apologies for not replying, this one went totally unnoticed. :( Well, the easiest way would probably be VMware. There are also open source options like OpenStack and Harvester.
Perfect explanation
Glad you liked it, AKHIL!
Thank you so much for that Video
My pleasure, Ikram!
Great, Stunning .. The best ever ..
Thanks, mohamed! 💪
Great video! Any reason why the network is not converged with the compute and storage?
Hi Sumitro! Thank you. Well, even with HCI you still need physical LAN networking. With some HCI solutions you can virtualize a part of the networking but not all of it. Today, that is. There are a few interesting initiatives around that have a potential to truly converge LAN in the HCI stack. One of these is VMware Projects Monterey. But until those solutions become generally available, LAN networking is not really part of the HCI stack.
thanks ...had to go through many materials do undertand this
My pleasure, Akash!
Very very helpful
Glad to hear, DG Petroni!
thank a lot , your video is great
Thank you very much! 👏
Hello Markus, I love watching your videos. can i know how you make these cools videos. and the transparent board ?
Hi, pharelwawi! Thank you very much, I appreciate your feedback! Ah, you mean lightboarding? ;) That's a very cool and simple method. You'll need a big thick and clear glass (with bright LED strips around it) in front of you, then you place a camera on the other side of the glass (about 3 meters away from you) and start drawing on the glass with fluorescent neon markers. Lastly, you need to flip the footage horizontally in post-production to make the drawings look correct to the audience. MAGIC! ;) You will find a lot more about this by googling "lightboard" or "lightboarding". :)
@@TechEnthusiastInc Thanks. this is awsome
@@TechEnthusiastInc Hi Markus and what camera model do you use to film
I am using Panasonic GH5 currently. Amazing camera! Highly recommended. Not a new model anymore but still very valid and price is very affordable these days.
Hi Tech Enthusiast.. Wanted to understand if network is also covered in HCI?.. I saw collapse of server and storage layer but not network in the session..?
Hi Aman! That's a really good point. If you ask HCI vendors, they will tell you that networking is also collapsed in the process but truthfully, in my opinion, it's not. At least not in the same way as compute and storage. It can be dramatically simplified using virtual networking like VMware NSX and the number of physical switches can be reduced but using these traditional approaches networking is not collapsed.
Having said that, there are interesting emerging concepts like VMware Project Monterey and smart NICs from Pensando, that have a potential to truly collapse the networking bit in the HCI stack but as they are rather new solutions, it's a bit early to tell yet.
Very interesting presentation.. One question please, how can HCI solution implement such a big ratio data reduction (50:1) ? Given that the traditional 3 tier infra is probably already using some data compression techniques I suppose.
Thanks again and keep up the excellent work.
Thank you, Mohamed! :)
That's a good question that I get a lot. It boils down to two things:
1) more efficient data deduplication and more importantly
2) combining primary and secondary storage (using one deduplication domain to be precise). Firstly, having more data to work with, data deduplication ratio improves. Secondly, most of the backup data just a lot of copies of the primary data (same data duplicated) so that data deduplicates very efficiently! This method increases deduplication ratio dramatically. To my knowledge, HPE SimpliVity is the only solution on the market to do this currently. Check this video for a brilliant (deep technical) explanation of HPE SimpliVity data virtualization process: czcams.com/video/DpXcyVMgK44/video.html
Hope this helps?
@@TechEnthusiastInc Brilliant :)
Thanks for your responsiveness Markus.
Keep going and your awesome videos and knowledge will surely keep on reaching to more audience ;)
Thanks Mohamed! I surely will do. :) Have a great day and stay safe, my friend.
Spot-on, Mark! HCI will always be more expensive than individual components. I always use a comparison of PC vs iMac. The extra cost comes from packaging the complexity into one appliance which brings ease of ALL aspects of ownership. Just like with iMac. There is a plethora and increasing number of customers out there who see the benefits of this approach and are more than happy to pay the premium. Just like with iMac. 😋
Subscription/consumption based models is a bit different topic, though. You can get started with HCI with or without subscription, independent of vendor.
If you break down the building blocks of HCI, you're right, it's nothing new that hasn't been done before (20+ years is a stretch, though). Like most things in the world are not. It doesn't mean you can't get excited of a Tesla even if electric motors, four-wheel driving and LED screens have been invented ages ago, right?
Based on my experience and talking to various different customers I am personally convinced that HCI is the best solution for most on-prem environments. Having said that, by no means I am against "legacy" 3-tier data centers - quite on the contrary. I am fascinated by all the storage arrays and server infra, more these days than ever. Some customers will always be better off with more control over their infrastructure and so all options should always be considered. Thankfully, haven't met any of those "HCI-only system engineers", by the way... 😉
thank you smart professor !
thank you for this explanation, where I work we now have the Hyperconvergence of Nutanix and There is nothing to compare to Traditional virtualization like VMware or Hyper-V.
My pleasure, Israel!
Our organisation is looking in to doing just that. Moving away from Compellent and VNX to Hyperconverged Nutanix.
Go for it! You'll love your new HCI setup. 😉
Is it possible to achieve #1(As hyperconverged as possible) and #2 (True appliance) at the same time? and what would be a typicall customer use case for choosing #1 vs #2? and could you also explain how 50TB becomes only 1 read TB in the hyperconverged disk?
Sry if it's a stupid question !
Hi Li! Thanks for the good questions. Absolutely it is possible to achieve #1 and #2 at the same time. Actually, if you think about it, they go pretty much hand in hand. The more components and aspects of data center infrastructure you converge, the more difficult it becomes to bolt them together. It will be much easier to converge components if you have total control of the R&D, engineering and support. And to your second question, if you decide to go for HCI, I don't see any reason not to try to have both #1 and #2 always, with every case. Since if you take it to halfway and use some HCI solution that is not "all the way HCI", you will not get the full benefits of HCI. So, maybe better to consider traditional 3-tier approach at that point?
That 50 to 1 terabyte is a result of some HCI solutions' data reduction algorithms like compression and deduplication. No data is lost, it is just compressed and duplicates removed. it is highly dependent on the type of data you are storing. Some data can not be reduced much, maybe some 4:1, while some data can be heavily reduced, maybe 200:1 or more. These techniques are not exclusive to HCI though, many storage arrays have similar features.
Thankyou for the educational video. As a student I had some trouble understanding what HCI actually ment, and everyone seems to be telling me just fractions of it, but you summarized it quite point on.
My pleasure, Lynx of Finland! I am happy to hear you found my video useful. Cheers! 🇫🇮😊
This is a great video and explanation, but I"m still a littel confused on where all of the data, networking, and compute sit in. Do these components sit in the cloud? Or do they sit on, let's say a Nutanix node locally?
Thank you, Elroy! If you mean the hyperconvergence nodes, they are installed in any data center like normal servers and data is stored on their local DAS drives. HCI is an alternative to traditional 3-tier data centers etc.
Also, let's not forget that "cloud" is someones data center too. In fact most hyperscalers (public cloud service providers) use some form of HCI approach too.
Good shit. Perfect explanation.
Thanks, bidhan giri! I am glad you liked my sh*t! 😂
Hahaha. Legend. Cheers.
Awesome!! but still could not understand the 50:1 data ratio.. is there any real life example?
Hi Rajesh! Sure, there are plenty of examples. These data efficiencies can't realistically be achieved with primary data only but when you store backup data on the same device, deduplication ratio gets dramatically better. This way it's not unheard of to reach 100:1 or even much higher. To my knowledge HPE SimpliVity is still the only HCI solution on the market that can provide this capability.
