8 minutes well spent. Thanks for a clear and concise explanation!
I used diontraining & professor messer but you are the winner hear for me in this explanation thanks!
This vedio is great, you really make clear between SAN and NAS...
Thank you
Thanks for explaining it in a simple way with examples
good work dude...if u can post few more videos about SAN it would be great ...appreciate ur work ..keep it up..
thank you so much....
awesome video ,very good explanation and it is very easy to understand .this video is very helpful
thanks...it gives me some refreshment on what i've studied in sch.
Nice video bro.. the way of explanation is very impressive...
great video, really well explained!
Thanks that was simple and clear explanation !!
Thanks for that, it's brief and precise.
Really worth full for a person to start learning
super!!simple and understandable!!!thanks dude!!!
Your shirt is a little too small
Great video. Very informative, thanks very much!
very good video..It broke out my confusion b/w NAS & SAN..gr8
You explained this concept very well. I wanted to ask a question about the san though: is it a device with multiple physical hard drives or a device with one big hard drive that you can virtualize?
thanks guys. very informative and simple.
Thanks for the explanation. As a feedback, I would encourage the presenter to utilize at least a power point presentation with lots of graphics to properly illustrate the concepts and functionality. Show, not tell, that was the motto during public presentation class. We have the technology available, and the blackboard is now near to obsolete. Besides, it is a little bit difficult to see the white board.
I'm curious why you wouldn't simply assign permissions to a NAS in a multi server environment instead of going the SAN route? in terms of distributed resource like allocating available storage to another server, that is about the only advantage I see SAN over NAS.
Please correct me if I have my logic wrong.
Hey thanks.. nice presentation.
I wanna know whether I can by pass NAS or there is an alternate to NAS.NAS routers are costly at my locality.I want to share my HDDs without using my system as HOST and keeping it ON all the time by pluggin the HDDs to my router via USB. any suggestion?
the glare on your prop setup makes it hard to see what your writing. very distracting, and not conducive to clear communication...consider RSAnimate?
Awesome. Good info for beginners. Important for interviews.
Yesterday I heard somebody talk for half a day about SAN/NAS iSCSI and FB.... You explained crystal clear in less then 10 minutes. Jood job.
very smart argument I would say. Now tell me whats the difference if someone will blow your PC/workstation ?
This is new to me. I feel I've bit off allot. We bought 4TB WD Mycloud EX2. It seems to have both options. It is going to be used for storing photos and video of the grand kids, with back up for 2 computers being secondary use. Am I correct is thinking the NAS architecture is the way to go? Would the computer back up files need a separate partition?
Or just mount a NAS in your filesystem and boom... you got it as a drive on your system just like a SAN on that respect.
im so stupid i thought this vid was about the rapper Nas lol
As a long time Nas fan who is studying for their Network + exam, I thought I was the only one that chuckled whilst reading about VM technology lol.
this was 2007 so i think thats how it was back then. I really enjoyed and learnt good off this video. thanks
A disadvantage on storing data on SAN or NAS is if someone blow the storage server, all data will be lost.
No, that would make it a mapped network share. SAN will show up as a real hard drive, like drive C:
Here's a question. If you map a NAS server to a drive, for instance, Z:\, does that make it a SAN?
clear.... but some one wrote "M" on ur head .... heheh no offence...great explanation though
Fantastic explanation! The lighting is impeding some of the whiteboard though.
Sincy many days, I've been looking for a clear simple explanation regarding SAN,NAS,FC etc and finally I saw this video. I really needed this thanks for lifting many loads off my shoulder..
or at least focus the light in a way that it doesn't completely blow the show off
Unless having backups ...why wouldnt you back it up?
Forwarding to my superior in order to educate him on differences of NAS and SAN
You seem you want to go somewhere ..
You didn't mention the routing issues. Might be good to add. Good vid.
@MrMashk you are funny dude...thanks for putting smile on my face.
I am really thankful to you for posting this.

Someone please help me out with the SubTitles !!!
It's ok for me to understand but some may find it problematic !
At 6:00 you talk about moving storage around in the server. Do you mean storage vMotion type of stuff?
Simple and easy to understand explanation. Thank you, Sir.
Switch off the light in the background, the text is not clear
Awesome Tutorial. Thanks a Ton. Will follow you. Ravi Raj
This was very good..thanks
I agree. Its distracting from an excellent tutorial.
People make this too complicated. NAS and SAN are both "shared" storage devices and are very similar. The only difference is how you connect to it. These days - most vendors are unifying their products meaning you can do both.
Nice explaination... pls give more video in future
2:20 - 2:24 should be NAS not SAN
good video....
it cleared my confusion..
good video basisc of san and nas have been explained
Slim fit dress shirts. You'll get the arm length you need but it wont be so baggy. Took me awhile to figure out why some of my shirts fit better in the arms and stomach and others looked like my dad's even though the neck and arms were right. 16 1/2 :: 34/35
+erik williams Its a 2008 videos... slim shirts are recent..ain't they?
Umm. Other workstations still have data on em
Excellent explaination within 9 minutes
thanks a lot. Verry good explanation..
Thanks for your video and time !
i can not see some things that you write on the board.
I've been using youtube for over 5 years now and today is my first day to actually comment on a video. You are GREAT, and very very helpful
Thank you!I understand just what i need.
hahahhhaahahahhah i was thinking too
Very useful. Please keep on posting
very useful, no words are spilt
Great video. Thank you. What is HBA?
Absolutely fantastic!!
Answered all the questions I had, been looking around for ages for just such an explanation!
Thanks!
Your shirt doesnt fit dude :D
Excellent explanation of the differences between NAS vs SAN, which is not very clear for beginners. Thanks.
Man I'd kill for that widows peak!
You are the man... simply awesome
Maybe in this context DAS (direct attached storage) might be an alternative. Its simply a storage expansion for a single server to be used as a block-device (like a NAS but without FC or iSCSI).
Usually its a raid-Controller with external SFF-8088 Ports (4x SAS/SATA per Port) (on a PCI-Express Slot) connected to an external Enclosure with additional hot-plug Harddrives. The external Enclosure has one SAS-Expander (it connects all internal drives) and often you can connect more cascading enclosures/drives up the limit the raid-Controller can handle (usually between 128 or 256 drives.
The performance is reduced to the 4xSAS/SATA-lanes and with a growing amount of drives the performance goes down. But compared to NAS/SAN the is very little overhead (no conversion to iscsi, FC needed) so you can scale up storage on a single server quite easily without needing to study certain NAS-OS (often limited by computing speed and latency) or spent tons of bucks for SANs and its complex setup. Additionally you are not limited by gigabit or fc connections. 10G is not cheap and teaming gigabit-connections does not speed up a single connection.
The main disadvantage is flexibilty: you have to shutdown the server and plugin-the raid-controller into others server if there are needed elsewhere. Also high-availability-setups are not possible (because the storage cannon switch to other server by itself/without physical interaction).
On the other hand most little and mid-size environments cannot afford fast NAS or SANs and need extra space/ I/O-performance for small money.
Very clearly explained, thanks for sharing. One thing I've never understood though is this - and the same would also apply to RAID, etc. Why not simply have an additional high capacity drive in the server that is backed-up by an external back-up drive? People say it's because this is not secure, but in my experience, modern drives rarely break-down - and if they do once in a blue-moon, that's what the back-up drive is for.
good presentation. thanks a lot.
nice job man. thanks. good video
I Thank you for this Video
Great explanation using real world examples instead of complicated IT jargon. Good job!
Thanks for the tutorial.
I liked the explanation very well, but ask? Can I store a web page or several web pages on the device, for business, hosting and access by users on the internet? .Thank you,
Outstanding explanation!! Simple and easy way to explain those context for beginners.
Thanks for the very simple explanation of these two different technologies. Helped me a lot. And I Subscribed :)
thanks for the video, lookin for more :)
Couldnt see much on the board though :(
No more video until now
well great vid. answered lots of my questions :)
Thanks for the video. Great explanations and easy to understand.
Get this man a fresh marker
Thank you for the video! This was exactly the explanation I've been looking for. huuge help
So you could network 3 NAS machines on a SAN? Right?
very well explained
very good presentation
Great work ...thanks
lol nice job with the lighting :P
