SCSI is the parallel I/o interface in between main adapter and smart device controller,possessing the ability to connect up to 15 all kinds of high speed peripheral devices
In the past i had to use iscsi to trick a programm on my computer to think that the raid partition on my NAS would be an internal harddrive. Worked great and i could even play games over it
you should add a pic of a sata hdd and a sas hdd, this shows that a SAS HDD can not be attached to a sata interface however a sata hdd can be attached to a sas wire even many sas controllers
I am not sure it is possible. This article talks about a SCSI to USB connection. www.tech-faq.com/how-to-connect-scsi-to-usb.html Maybe is you could connected the energy meter to a computer and have a computer emulator a floppy drive that may work. Not sure how you would go about doing it.
I know your just providing just a general overview, but last time I had anything to do with legacy SCSI the controller also had a SCSI ID. A Comment on that might be in order.
I would say you would be able to, assuming they use the same type of SCSI. A lot of external devices back than used SCSI SE, so the bus should reduce down to the slowest device on the chain. Can't say for sure it would work, but good chance it will. Just make sure that you give them different SCSI ID's.
I've been using SAS for years now already and what he talks here is mostly gibberish, theoretical but not real-world, in real world only 1x to 4 device sas is possible at most (and is usually the standard, oddity when less that 4 headers are coming from "minisas")
You are aware that SAS is often used for large storage like SANs and cloud storage? These have a lot more SAS drives than that. I worked on a server recently that has 20 SAS drives connected via RAID to local storage. I am guessing you only have work on individual drives.
@@itfreetraining it's been 7 months and I don't remember what I commented about, but MiniSAS is up to 4x, those servers have many mini-SAS ports, not 1 My servers have only built in 1 or 2 minisas headers but adapters and what's it called - the middleplate have many ports

Yep and there's a lot more to it, mentioned in the video.
Your channel name encompasses perfectly what you do. Instant subscribe.
Glad you like the videos and thanks for the sub.

Sounds good. People still use iSCSI to do that. It is a cheaper option than using fibre channel.
Scsi is scaring me in my studies, i just need on hand training to understand it more.
It is difficult now days to learn since the technology obsolete.
Thank you fella you really helped me out in understanding
Glad it helped

Wow, Fantastic. What do you think in this videos, everyone?
I think: Is SAS only bidirectional over the two physical connections to a drive or also on one connection?
SAS support topologies. So you can connect multiple SAS device together. kind of like networking for storage.
Thanks for this amazing Video.
Thank you
Thanks. Great vid and clear explanation.
Glad you enjoyed it!
Thank you
You're welcome
Man, no dissuasion of high voltage scsi? I had a 3590 that was a pain to get working because of the card type needed.
We have a newer version of the video which look at this topic in more detail.

Thanks
Thanks very much.
This was great. Do you have a video like this for PATA/IDE?
Glad you liked the video. Here is a video on IDE/PATA

dude you are great
I appreciate that!
Hi sir
Please upload videos for cloud.
We are working on A+ course at present. Will consider cloud videos later on.
i have an energy meter, uses floppy with scsi 26 pins, i don't know how can i adapt that to an emulator floppy, to use an sd or usb flash,
I am not sure it is possible.

Maybe is you could connected the energy meter to a computer and have a computer emulator a floppy drive that may work. Not sure how you would go about doing it.
You got your bits and bytes mixed up in your definition of SCSI and IDE speeds. Both should have been in megabytes per second not megabits per second.
Anyway to recover the data off of these hard disks?
Depending on what the problem is, there are options available. Given the age of the technology now would make it difficult to get parts and equipment.
I know your just providing just a general overview, but last time I had anything to do with legacy SCSI the controller also had a SCSI ID. A Comment on that might be in order.
That is mention at 5:00 in to the video. It talks about the switches or counter on the back of the device to set the SCSI ID.
@@itfreetraining talking about the controller itself. Most people wouldn’t consider the controller to be a device in the chain
@@norlag I see what you are saying now. Yes, we did forget to mention that.
@@itfreetraining yes on my Adaptec 29160N PCI Ultra160 SCSI card it designates ID-7 for the SCSI controller.
I generally asking me from where the "A" came into the pronouncing ? Small Computer System Interface...... SC "A" SI ? ;)
It’s just how it’s pronounced, impossible to pronounce a word without vowels
It's actually pronounced "scuzzy".
can you daisy chain a scsi jaz 1G off of a zip 100?
I would say you would be able to, assuming they use the same type of SCSI. A lot of external devices back than used SCSI SE, so the bus should reduce down to the slowest device on the chain. Can't say for sure it would work, but good chance it will. Just make sure that you give them different SCSI ID's.
cable managment was a mess ;D
SCSI could get messy when you had a lot of devices daisy chained together.

There's no gibberish mentioned in this video.
Really nice 👌 😍💋 💝💖❤️
