This is THE BEST explanation of RAID parity explanation hands down. The youtube algorithm works in strange ways though. Thanks Alot anyhow 🙏

The music is a disadvantage ,that's a relaxing music which can make one sleep very easy

One of the best explanantions on raid terminology out there, unfortunately bit of a misleading low quality intro though!

My colleagues want to marry with DellEMC and VxRail. Is it a good idea, considering that it is NOT commodity hardware and we will become locked-in to a single vendor ? Also HCI doesn't look as a greener technology given that the CPUs which used to be offloaded from PIO IOPS (programmed input-output), now will be tasked to convert every single I/O into TCP/IP packets to make possible the software-defined storage of the HCI (unless vendors add a proprietary magical black box to act as a filesystem accelerator).

Please leave out music. It is beautiful but sometimes disturbing expecially when you need to repeat and concentrate. Besides a great explanation Thank you!

your voice is sweet oh dear

The complex subject is broken down into simple one. Thank you.

thank you so much for sharing these videos.

The volume is too high.. Please reduce it

Best introduction to Object Storage I’ve found. Thank you!

Only portalone....

What a short memo explaining the concept the VDI

Ask questions what is the concept in VDI

thanks

This is by far the most clear explanation I have been provided with ever. Thank you!

thank you so much to keep it short and straight

Excellent video. Would love to watch more of such videos of yours.

Good article of this here! downloadchan.com/category/geek-blog/

Learn how to install type 2 hypervisor (Virtualization) practically from the following link: ruclips.net/video/FCUf8yxHy9A/видео.html

Jumped right into the deep water with FF as 255 with no explanation of how that is.

Well, the video quite explains the comparation between tradicional architecture and Hyper converged infrastructure (HCI). There are some assumptions that are in part accurate. HCI systems does not need to grow in compute anytime you want to grow in storage. One of the main advantages of HCI system is that you can Scale up (add disks to existing nodes) of scale out (add nodes, thus compute+storage). Obviously to scale up you need to have free disk slots in your servers. On the other hand, storage array (at least midrage ones) are compound by 2 controllers, and you cannot add more. So the only way to grow is adding disks in new enclosures, but you are limited to 2 controllers. High range arrays (Dell PowerMax ie.) can grow bot in disks and controllers. About networking, well, the bottleneck would be your switch not the HCI nodes. HCI nodes already can use 25GbE NICs, so you can aggregate and create a 100GbE link to your Top Of Rack switch. Don't think the network could suppose an issue here, although it is true that has to be carefully configured to get all the performance. To finish, HCI is not intented for all kind of workloads. It works great for VDI environments, migration from already virtualized enviroments, even big data, but it is true that it not intented for extreme compute (HPC) or huge data set processing. Regarding to the cost, you are having into account only CAPEX, but you are not talking about operations (OPEX). HCI systems are MUCH easier to manage, to set and the lifecycle management it quite simple. So the provisioning and service delivery is faster and more granular, saving time and reducing error posibility, thus saving OPEX.

Thanks.

Doesn't map the over but give a high-level digestible overview...I got allot out of it

wonderful

My professor said my computer had to be connected to a VDI. I had no idea what that meant, so here I am. 🤷🏾🤷🏾🤷🏾

clear as water, tx

Thoroughly enjoyed this. Thanks. Much appreciated.

You might need to explain Prescriptive analytics more

Correction: in DellEMC’s VxRail HCI Solution you can grow storage without growing compute. There are typically many drive slots available across a 4 node cluster. You can also grow compute without growing storage. When both need to grow you add a node.

Well presented & easy to understand. Thanks.

very excellent

This video is great, But now has become outdated a bit. Some of those buts are no longer valid. Nutanix for example has Storage only nodes, so you can scale storage without "compute"(its not perfect but it does exist), and also Supports Physical Workloads through ABS. And since they are market leader, most of the time at least, This represents a large amount of the HCI deployments. Also Nutanix has data locality and Vsan has a lighter version of it, So network is not really an issue, Not saying a network issue doesnt exist. But I would argue that a SAN's Network is just as much a bottleneck. Also Vsan has the ability to attach a SAN to it, and the vms running on the nodes can chose between the vsan datastore of the SAN's datastore no problem, which is pretty unique. And Simplivity can be used as the storage target for non HCI servers if needed. I do think there are reasons why HCI would not always be a good fit, As i often face those issues. But each year its becoming less and less as new features are being added, and the size of disks grow. The main one i face is when a customer just has a mass amount of storage compared to compute needs, HCI would be incredibly expensive in those cases. Some of the previous things that use to be a showstopper, Databases now have tons of support, as mentioned there is physical workload support on Nutanix. File Services are amazing, completely competes with enterprise NAS's. And running the systems is incredibly easy, Its basically storage for dummies with just as much capability. One of the biggest issues with HCI however is the cost, Its usually a much higher upfront cost. Without doing Proper TCO/ROI calculations, it appears to be more expensive than 3 tier. But it actually is cheaper. SAN manufacturers completely rip off customers with their 3/5 year renewals, basically forcing them to upgrade. SAN networks are insanely expensive, and outgrowing your SAN, which is happening more and more today, Means a lot of rip and replace. HCI is truly scalable.

good video, thank you for the efforts

This video is trash you can hands in the wgat? I leanre nothing from this

How do Nutanix stack up in this group now?

If I am understanding this correctly then that means Thin Provisioning is the same as Dynamic Storage?

Thank you very match , for the presentation and the advice

Thanks understood more in details.

Great explanation . Thank You

Nice and great explanations thanks

The "But's" are not all true.

helpful. thank you.

So we are returning to mainframes :), nothing new here. A device with local storage, CPU, memory and a network switch.

Wow, so clarifying. Thanks a lot.

Beautiful

i have a question that who invented server virtualization? is it microsoft,linux,oracle,vmware or citrux
