SCSI 

Glad you like the videos and thanks for the sub.

Yep and there's a lot more to it, mentioned in the video.

We have a few videos on SCSI. The older ones go into more detail.

Sounds good. People still use iSCSI to do that. It is a cheaper option than using fibre channel.

Glad it helped

It is difficult now days to learn since the technology obsolete.

Glad you enjoyed it!

Thank you

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.

I appreciate that!

You're welcome

Thanks very much.

We have a newer version of the video which look at this topic in more detail. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-jmiZ0gEBEk4.html

We are working on A+ course at present. Will consider cloud videos later on.

Glad you liked the video. Here is a video on IDE/PATA ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-CF_copQaORQ.html

It’s just how it’s pronounced, impossible to pronounce a word without vowels

It's actually pronounced "scuzzy".

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 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.

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 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.

SCSI could get messy when you had a lot of devices daisy chained together.

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

There's no gibberish mentioned in this video.

Thank you! Cheers!
