Also in full agreement with LakeAvalon1..by far ( for a novice ...me) its the absolute best understandable explaination of RAID. Spent multiple hrs online trying to understand in, layman's terms ,RAID.Great Job

Congrats

It is a complex yet simple matter. And important to know what to choose when you set up your RAID levels.

9:10 You said having 10 hard disk drives is 90% of chance of losing all the data. However, if the pieces of information (chunks) will be divided by ten on each drive, doesn't that mean that the more drives you have the less read-write process each drive will have? If so, then can we say that the less drives we have, the more chances of fault we're gonna end up having because all the read-write processes will be focused on fewer drives? Just a thought I have.

Great lecture and very good instructor. How I wish I go to this school where he is teaching. More Power teacher.

Great lecture. Much appreciated

🎉🎉🎉🎉

The best educational video!

Can foreign students do the course

I watched a little extract couple of days and I had to come back today to subscribe and hit the notification bell. Downloading it is inevitable. Thanks a lot, Sir.

BEST!!!! RAID Lecture!!!😀😇 well done J Martinez

clear and helpful 20220311

Thanks a lot for this lecture. Will go through the entire series. Crystal clear explanation J Sir.

Thanks a lot for the very informative video in computer networking.

God bless

This is great! Thank You

I just watched a whole lecture, and I just wanted to make a Minecraft server

Well simplify professor, thanks a lot for this lecture.

Awesome video!

You impresses

Thank you so much for this - you made it so easy to understand.

Was the last line sample in the firewall created only for a ready made secure protocols be set as soon as it is only needed?

Very clear and detailed explanation of RAID

Brilliant presentation / lecture.

Poor explanation really. RAID 10 is all over the place in here. Which are considered the PRIMARY and SECONDARY disks? And why is mirroring done before striping? If you do striping then mirroring you'd have a different arrangement of hard disks. Each school seems to have its way to explain this.

Great explanation, I liked the real world examples that you gave based on your experience!!

A nice video!

Thank you so much, this is really helpful <3

Thank you, a good video.

where can i see updated videos of this guy?

at 34.52, I think Dear Mr. Asher you had mad a mistake, which is when you wrote 100 GB Disk capacity will lost. the correct is 50GB, because when you give the example of 4 disks each has 2TB, the answer was from your student was 2TB same as your example was. I hope you get me dear. Thank you too much for you.

During the rebuild the lost Disk, is D driver will still working on network very slowly, or it will be stopped till the rebuilding finished?

At 28.33 what is the back up of the cancelled parity disk?

what is the name of this trainer ? Whats his first name?

How do we deny the other half subnets? ie from 128/255?

thanks a lot so interesting lecturer

Teach me and I will give a lot of love and shares :)

The RAID 5 Parity bit isn't "compressed" the way you describe. The RAID controller knows how many drives are in the RAID, then it counts the 1s for each block level. If there's an odd number of 1's the parity bit for that block level gets set to 1, if there's an even number of 1's the parity bit gets set to 0. If any single drive fails, you can reconstruct what the missing bit was by counting the number of 1's at each block level from the remaining drives and then figuring out whether it was a 1 or a 0 based on what the parity bit says it should be. There are more nuances to this explanation, but it doesn't use dictionary compression the way you explain... that would be far too slow and take up too much memory at this low-level of operation.
