Thank you! Proud to be a systems engineering student

Your background noise is too high

Great video but the background music seems too high.

loved your explanation bro.

Awesome, clear explanations!

Very clear & easy to understand 👍

Thank you for doing what you keep doing. You're very clear and explain it in such a simple way it's easy to understand.

Please do one with more info on iscsi :)

Hey Charles! Watching this video a few years later. Where's the follow up video? 😂

Your channel is so underrated… great content!

I respect the points you’re making, but they are very much not reflecting the reality of what is happening out there. As a VMware partner, I can tell you that while organisations don’t want to move, they have to and very much have been. You give an example cost increases of 1.5%, you need to stick a few zeros on that. Take education or a charity, a renewal was a partner price of around €37. Now, €3950. So no, bundles do not make any sense when it pushes the price up that much. Small businesses, education and charity simply can’t afford that. You also mention the sleeping partners. What about distributors. Our one and only distributor in Ireland has been dropped. We now have to buy through the UK. I could write an essay about the disruption this has caused. I’m on the ground representing a few hundred customers, this is anything but a bump in the road.

Cuz young people realised u can work until u die and be poor but there are people who never work in their whole life and are millionaires/billionaires

I feel what you are going through Charles 🙂 cos' I'm grinding through the process and as Mr. Beast advised, don't look at the #of views, or #of subscribers. Focus on good quality content and how to improve on your next video, and soon enough, we will get there. Jiayou together! Actually I'm quite excited to see you back on TH-cam haha!

I understand your feelings of your ups and downs. It is never easy but thanks for the hard work you have put in. Yeah, I can relate to the early fixation to stats, but the right way to keep things easy is to share your knowledge and experience and expect little in return. You are right that even if your channel has made a difference for one person, that would be a job done well. I kept my blog going for 13 years now, and at one point, releasing one blog per week for 4+ years, consistently. It is my love for the technology industry I am now that I kept on going. So, well done and keep it coming!

You said it very well. I was born in 2004, therefore I am a so-called "gen-z". It is like you said, it is not the individuals' fault, but the way society has developed today.

Suck ups mad that the hopeless don't care

Wow checking the stats every hour hoping for something to change I FELT that 😜

nice explanation

Do you need to understand more about storage performance? Iops, latency and throughput? Check out this video.th-cam.com/video/JUrU_DOq6YM/w-d-xo.htmlsi=8UQCuSlG9OL5EJaj

Interesting video and thoughts. Separate topic, how can you put Starbucks instant coffee into a Nespresso mug? Oh no..... :P

Hey Charles nice video, somehow I can relate very well to this story as if I was there :), interesting to see it from your side. Thanks for sharing

Appreciate for sharing your point of view, each one of those makes sense.

Charles, I enjoy all your videos, its simple and easy to understand for anyone. Thank you,

Good discussion Charles. Agree!

To me, staying at a job for decades just shows me that you only like to do what you're comfortable with. You're afraid to get out of your comfort zone. And anybody can do your job it doesn't make you special just because you stayed at one job for long. I actually believe that the more experience you get in different jobs, the better of a worker you are because you like to learn new jobs, new skills, new perspectives. Job hopping is the true talent. Sitting at one job for over 10 years makes ppl want to kill themselves

I am undergoing a bad patch at work and come across your content. Thank you to your wisdom and experience, i feel much better understanding how can i perform in future in my company.

Hi, I have about 9 years of experience in IT, currently working as a cloud engineer, like to move to enterprise storage domain. Please suggest a path.

Fantastic explanation of the upper per VMDK and per node limits of vSAN, and why traditional benchmark tests tend not to paint it in a positive light. In the spirit of full disclosure, I work for NetApp and fell into the trap of assuming vSAN would offer the same traditional SAN/NAS benefits I have come to take for granted in my 18+ year tenure as a Solutions Architect. For instance, in my first single VM single VMDK test I achieved over 2000 MB/s to the NetApp NAS device over NFS (25GbE), and only ~70MB/s to the vSAN doing a very standard fractional block (sub 1K) billion file write test of AES generated random data. A real-world workload without a doubt (from a telco customer of mine who had a customer service app that wrote many small files), just not a workload that vSAN could ever handle (unless the app were re-factored to run across many VMs or containers vs a few monolithic VMs). By the time I got to 4 VMs running a more reasonable block size 64K at closer to 70/30 RW mix, the performance of vSAN achieved fully 3/4 of what the NAS/SAN array could do. Bottom line, vSAN can be a great fit for certain I/O profiles and is evolving nicely to fill many spaces where SAN/NAS might be unnecessary. The important thing is to profile your workloads, and plan to stay ahead of that point where single VM performance becomes a limiting factor for your real-world application. The great news is that vSAN and NAS/SAN devices can operate side by side even on the same cluster, so for situations where the application cannot be re-factored or optimized to break the workloads into more optimal blocks of work, an external NAS can plug right in and offload that noisy storage workload before it grows to be a problem! Both VROps and NetApp Cloud Insights do an excellent job of graphically illustrating the potential choke points in your VM performance (exactly as you showed in your graph of IO vs latency) to help optimize your storage and make wise storage back-end choices. Thanks again for this video and for pointing out HCIBench as a nice overlay to VDBench and fio. Very understandable and helpful in framing conversations about which VMware clusters will benefit from external storage versus which will not require it.

Personally, I've always considered snapshots to be a "System Restore" solution. Great for recovery in case of issues with updates (highly recommended when using rolling release distributions). But not a backup solutions. This is why my snapshots are configured to only create a new snapshot when I install, remove or upgrade software. It also makes sure there are no more than 10 snapshots available on my system, by removing the old ones daily at 7 P.M.

Well done, Sir

Can this be mounted in 10" rack? Are there brackets for it?

Pls Reduce Volume of you background Music..

Excellent video! I learned a lot. BTRFS was designed for massive enterprise installations. It is slow on home desktops. DJ Ware did an excellent comparison of file systems. F2FS shines on home desktops with SSDs and is what I use on all my systems. Snapshots can lull people into thinking of them as a real full backup. It is much better to create a full system image or functional clone, plus extra backups of irreplaceable files in Home, configs in etc, and the like.

Please remove this music!

Can you please update or remove this video?

So much better it had been without that background noise! (music?)

The market trend can turn around very quickly. In fact, the indexes often switch from a bear market to a bull market when the news is at its worst and the mood of investors is at its lowest point. I read an article of people that grossed profits up to $150k during this crash, what are the best stocks to buy now or put on a watchlist?

Looping the same sound over and over again on a rather high volume is no sign of intelligence

Man, you've helped me a lot with this video.

I've been thinking it's quite like this indeed. I've been using snapshops like before bigger system changes that could result in undesired concequences. But I still try to do like weekly backups.

why the needs of music while teaching?

Hello Charles! Thank you for the video is so informative! I have a question. Could you remove an intermediate snapshot and keep one from long ago? The objective would be to have like some kind of "backup" once a month (with snapshots) allowing time travel to check how the data was 1 year ago and also like for example the last 2 days. If this is possible you would delete a lot of data that we don't need. But I'm not so sure that if I "break the chain" of the snapshots I will be able to access to data from long time ago.

Fantastic video! I learned a lot. Thank you. I always feel like the abstraction of data storage and accessibility/interface options have just become overwhelming. Maybe I'm dealing with FOMO haha. After a deep breath I'm just glad to see that rsync is will being used in industry and home labs! Finally a tool that hasn't been supplanted.

bro the music - stop
