I am back to this video after a month, a great refresher on which disk performance metrics to look at. Thanks again John!

[@manishkaushik2506]

Thanks John for such amazing content, will really look to future deep dive videos on other Azure Services!

[@ivanshopov4477]

Amazing! Better than all the payed courses I have ever seen! Thanks !

[@prakashq2020]

Great content John, appreciate the efforts put in to explain things :) . Please keep posting !!!

[@diezam]

Thank you for all your hard work, your videos are fantastic

[@NTFAQGuy]

Glad you like them! Thank you!

[@kiraninam]

What a instructor. Sir please keep your concepts details and in-depth. You are different , skilled and respectful

[@NTFAQGuy]

I appreciate that!

[@karemallouji8123]

That is a very well made deep dive, and i learned so much today. Thank you

[@NTFAQGuy]

Awesome, thanks.

[@electroalon]

Dear John , thank you for all your videos !!! I am learning for AZ-104 and this is MEGA helpful !

[@NTFAQGuy]

Great to hear! Good luck!

[@iamdedlok]

Thanks John awesome video. Summary on Bursting: The Richer you are, the more Loan you can take. Amen.

[@NTFAQGuy]

Thanks!

[@timorolle5029]

Awesome job! Fantastic explenation which helps a lot for understanding and optimizing!

[@NTFAQGuy]

Thank you.

[@stevenross3577]

Great content...comprehensive but accessible...thanks John!

[@NTFAQGuy]

Glad it was helpful!

[@C-Swede]

Great content as usual John, thanks! I’d like even more understanding about Ultra disk, it has some quirks with what it can and cannot do. Would be great to hear you speak about how to use it in designs.

[@johnherlihy9907]

Thanks for this JS - I thought I already knew this stuff, but you've just opened a can of education on me. Great comparison between the different tiers of Managed Storage, particularly on how bursting works.

[@NTFAQGuy]

Awesome, glad could spread the azure joy :)

I was going to write exactly the same comment.. Bursting explained the best way possible. Thank you!

[@veepee555]

This is Brilliant John...

[@bkrich]

Great information, thank you

[@christianibiri]

As usual this is awesome, thanks John 😀

[@NTFAQGuy]

Very welcome

[@jatinnandwani6678]

Thanks so much John

[@zt.5677]

Thank you! Lots of new info.

[@NTFAQGuy]

You bet!

[@osuraweerasinghe5516]

Thank you, Great content :)

[@yulaw3289]

enjoying this video for today learning, thanks a lot!

[@NTFAQGuy]

Happy to hear that!

[@jlou65535]

So useful as usual thanks John 😎

[@NTFAQGuy]

Glad you think so!

[@jlou65535]

@John Savill just 2 questions :
- As you said for your dsv3 VM, you also have a Max burst uncached disk. Therefore, do we might 2 x 30 minutes buckets (VM + disk) for burst performances, isn't it ?
- As you said, managed disks are also stored in a storage account. If we have 2 data disks on one VM, do they will be stored on the same storage account ? Therefore, will we have 2 x shared disks’ IOPS ?
Thank you 🤗

[@NTFAQGuy]

@@jlou65535 each managed disk has own IOPS etc. vm has one bucket of burst not per disk

[@hrvojetonkovac6519]

Love the video.

[@NTFAQGuy]

Thanks! 🤙

[@jan2ary]

Ultra Disks are really cool, but for now they are available not for every VM sku (e.g. West Europe and Standard_DXXds_v4), and also Linux is not able to provide direct IO for them.
But they are even cheaper for Oracle's redo log filesystem comparing to recommended P40 because of small size and high enough throughput ans IOPS.
And thanks for the comprehensive and informative video!

[@IncorrectTarget.]

Marvelous

[@hardikdesai24]

Thank you John for the detailed explanation about managed disks. Can you please share the whiteboard sketch? Thanks.

[@NTFAQGuy]

Read the description

[@artisticcheese]

I think very important topic about pricing was not covered, that is that one pays for each IOP in HDD, SSD but not in Premium SSD and hence depending on workload you might end up paying more for HDD, SSD then Premium SSD

[@NTFAQGuy]

I did mention that.

Liked before "...as always if it is useful a like, comment and share is appreaciated and hit that bell icon to get notified of new content and when I do live events..." message.

[@swapnilshivankar29]

Can you just make a video on azure calculator. I like to know the detailed pricing of resources. If I have to quote a price to a client I am not able to calculate all resource price. Example like vm instance or app service plan. Because I miss to add some of the resources while calculating.

[@NTFAQGuy]

That would be very scenario driven as to what elements to add. I could create such a video but just wonder how useful it would be. Anyone else want to see this?

[@EasyEngineeringStudies]

@@NTFAQGuy video should be made on this. There are lot of things that need to be consider, where there is no clear picture what resources should we add, to get perfect cost of that resources or services.

[@jserpapinto]

Thanks for the class. How can I pay you a coffee or a beer?

[@NTFAQGuy]

hehe not required but thank you. Just subscribe ;-)
