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 !

[@TechEnthusiastInc]

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.

[@aman2688]

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..?

[@TechEnthusiastInc]

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.

Hi how does the scaling work. I believe it will be by nodes and that's where the problem of under utilization props up. Also client demand a fully flexible consumption based pricing that is not possible in hyperconverged models

[@TechEnthusiastInc]

Hi, Ajay! Yep, scaling has traditionally been one of the downsides of HCI. However, with many solutions you can actually upgrade nodes internal storage and compute capacity. Start small, scale as you grow. If you need totally independent scalability, check out "HCI 2.0" of which good example is HPE Nimble Storage dHCI. With dHCI you can scale compute and storage independently but still manage the entire stack like any HCI. I'm not sure what you mean by "consumption based pricing is not possible in HCI models". Consumption based pricing and infrastructure choices are conceptually two different things. First you choose the hardware you want to run the workloads on, then you start monitoring resource consumption and finally you charge the customer based on consumption. HCI can very easily be used for this approach.

[@ajay7724]

@@TechEnthusiastInc what i mean is the service provider has to add an additional node when the consumption goes up but the client may not be ready to pay for the entire node but only to the extent of volume consumed. Thus the service providers cost will be more than what they bill because of under utilization of node resulting in incurring a loss. Let me know if there is any solution to this.

[@TechEnthusiastInc]

I know what you mean but there will never be a solution that perfectly aligns with the customer consumption. Consumption based models are based on the service providers risk and that's what the service provider is charging for. Most, if not all, hyperscalers' data centers are build on HCI concept too and they have the same dilemma...the better they are able to forecast the customer consumption, the better they profit. But they too will always have to overprovision just to add that extra headroom because the worst that can happen is for them to run out of capacity. Now, adding an additional HCI node is comparable to adding a drive shelf or a whole new array, right? At some point every (sub)system maxes out. It's a question of how often you need to do that and how much does it cost for you to add new hardware. With HCI your building blocks can actually be very small these days, you can go for 1U, 1 CPU nodes and add them very gradually. This all depends on the scale of business and customer requirements. With some cases traditional 3-tier might be the right way to go but with many cases HCI can be a better solution than traditional approaches.

[@murtadhaghanim7263]

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,

[@TechEnthusiastInc]

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.

[@manojkumar-lt6wk]

So multiple X86 servers are placed like an array in one data center? If this is the case, do multiple processors work together?

[@TechEnthusiastInc]

From compute perspective it's 100% a hypervisor cluster. So, one VM/container can only utilize vCPUs from one physical server at the time. They can move around in the cluster but there's no common pool of CPU cycles, unfortunately...that would be cool! Like HP-UX does it with vPars. 😉 The storage, however, is one big common pool consisting of all the accumulated capacity in all the nodes in the cluster. Different HCI vendors have different mechanisms to implement this but the principle is the same.

[@omkarnalawade97]

@7:48 how does that work?

[@TechEnthusiastInc]

I was specifically talking about HPE SimpliVity's Data Virtualization Platform and it's feature called global deduplication. Instead of sending the whole hydrated data over the network source cluster first tells the target cluster what data it is about to send over, target then replies what data it already has so source only needs to send the missing data over the network. This alone dramatically increases performance and eases bandwidth requiremens. Additionally, since all clusters are part of the global federation, all data that is sent over the network is deduplicated and compressed. All of the above eliminates the need of dedicated WAN optimisation. Incidentally, I am getting a SimpliVity node pair from HPE shortly and will definitely touch this topic again so stay tuned! 🥳

[@vaytess]

Please if you can help explaining the difference between HCI and Private Cloud concepts

[@TechEnthusiastInc]

Good question! Let me take a bit longer route with this. First of all, to me cloud is an end user experience, it's not about a location nor infrastructure. It's all about running your apps as worry-free as possible. Underlying infrastructure is irrelevant to the end-user as long as your apps are running and you are only charged for the resources you actually use. Public cloud providers have built insanely massive data centers and sophisticated automation layers (backend orchestration software + websites etc) on top of the infrastructure to hide all the traditional complexity from the end-user and deliver that cloud experience to the global masses. However, and most importantly, cloud experience is not public clouds' prerogative! If you have the automation layers, simple-to-use end user portal, flexible infrastructure and all the required financial processes in place, you can provide that same cool cloud experience with your own DC. To build a private cloud as such, underlying infrastructure needs to be as flexible, scalabe and easy to manage as possible. You CAN use whatever servers, storage and networking as you wish as long as your automation layer can fully manage them. However, some modern infrastructure approaches are easier to use with these kinds of situations and hyperconverged infrastructure (HCI) is one of them. HCI is build for easiness, full API remote management and hardware consolidation in mind. That's why HCI is so popular as the base building block of a private cloud infrastructure. However, you don't have to have a "private cloud" to take advantage of HCI, it is a very appealing way for all organisations to build an efficient and easy to manage private DC, small or large, "cloud" or not. Furthermore, finally now in 2020 all major providers (traditional infra vendors like Dell, HPE and NetApp and public cloud service providers like AWS, Google Cloud and MS Azure) agree that the future of IT is and will be hybrid: some apps run in public cloud, some of them run in private data centers and some computing is done at the edge. It will be super interesting to see who will master this hybrid cloud experience best. My crystal ball is quite undecided, it can go whatever way at this point. ;) Hope this helps?

If you put the storage inside the server, how do you scale storage? By adding more servers? What if I want only more storage?

[@TechEnthusiastInc]

That's a very good question, George! The short answer is: difficultly. 😬 The longer answer is that while this is one of the caveats of HCI in general, there are ways around it. For example, with most HCI solutions you can actually start with small internal capacity and add more DAS drives as your needs grow. When you run out of nodes internal capacity, then you need to add another node. Some HCI vendors (like Nutamix and NetApp) also allow capacity-only nodes, with limitations. Then, there's HCI 2.0 of which HPE Nimble Storage dHCI is a brilliant example. The compute capacity is provided by standard HPE ProLiant DL servers and HPE Nimble Storage provides the storage capacity. Nimble capacity can be scaled totally independently of compute capacity but you still manage the entire stack as you'd manage any HCI stack. Hope this helps?

[@thexavier666]

[@TechEnthusiastInc]

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.

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 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.

[@TechEnthusiastInc]

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.

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... 😉

I'm working for a Riverbed Partner we have a solution call branch Converged infrastructure, it's not for Datacenter but they merged Servers, Hypervisor VMware, Storage, and Backup obviously WAN optimization because riverbed is the leader.

[@TechEnthusiastInc]

Very cool! So, is it a software solution that I can install on any x86 server?

This is a very great explainaison !! great job. And how do you write and film on the transparent whiteboard ?

[@TechEnthusiastInc]

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 KZbin 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. ;)

[@DarudeSandstormVEVO]

do you have to write in mirror writing all the time??

[@TechEnthusiastInc]

Hehe, I wish I was that talented. ;) But in reality, the magic happens in post production where I flip the image horizontally. That process makes me look like a leftie, tho...but you can't get everything. ;)

[@elroyjain]

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?

[@TechEnthusiastInc]

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.

[@razadaza9651]

any thoughts on vendor redundancy?

[@TechEnthusiastInc]

Hi Raza! What do you mean by that?

[@razadaza9651]

@@TechEnthusiastInc so if a particular vendor is incapacitated or has a system outage or vulnerability where they cannot resolve an issue… what do you do then?

[@TechEnthusiastInc]

Based on your question I assume we are talking about a highly critical environment and so in these environments there are multiple ways to secure this doesn't happen: 1) If your production is working, don't touch it. 2) Only update firmware if the new features are absolutely crucial to you or the update is marked as critical by vendor. 3) Update firmware only after it's been available for a while so that you can see reactions from other users and the vendor. 4) Update firmware first in a test environment and thoroughly stress test it to detect problems. 5) Reserve proper window or upgrading the firmware in production to tolerate possible problems. After implementing these measures properly, there's an extremely low possibility for any malfunctions. Independent of vendor. Of course, you should still do external backups to secure the the data in the event of a total disaster. There are multiple ways to do this with different solutions. And oh, individual node outage doesn't bring down any HCI system, redundancy is built deep into all HCI systems. Generally, all major HCI systems are super robust. So in 99% of the cases you don't have to worry about any extra measures as long as you follow vendor guidelines setting up the systems. If you still want to bring other vendors in the HCI mix, it's going to be replication since you can't use, say, Nutanix and Simplivity as one system but of course you can copy data between them. However, if you ask me, that kind of mixed environment most of the time leads into more problems than solves them and creates complexity that is most probably unnecessary.

[@razadaza9651]

@@TechEnthusiastInc thank you for your detailed response. Any thoughts on vendor redundancy with a production outage with significant downtime where there is no way the vendor can remediate within SLA? Or even of Vendor obsolescence overnight say due to administration etc… Vendors getting hacked etc… Sorry if these are silly questions… it maybe difficult to have a multi vendor setup? Maybe a different vendor at a different site to back each other up?

[@TechEnthusiastInc]

If/when your environment obviously is highly business critical, if not mission critical...you should only consider vendors that have the capability to provide high levels of 24/7/365 instant support and on-going monitoring and preferably have a dedicated support person/team only for you. Most enterprise vendors offer very high levels of support and SLA guarantees so there are ways to almost 100% guarantee that systems work at all times. And if they don't, they are responsible or accountable (depending on the contract) to compensate the damage. Even better, many vendors are offering Everything-as-a-Service consumption models these days where the infrastructure is running in your premises but the vendor will take care of running it. This would be the best solution to make sure everything will run as expected. Long story short, I would avoid mixing vendors unnecessarily in this case and solve the problem with support and services.

[@DinushaMadusankaChandrasinghe]

Good Work. SAN Switches also include into the network Layer

[@TechEnthusiastInc]

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.
