Welcome back to Cyberia. IittIe. My name is Justin Lengel. Today we'll be covering Cloud. Plus, we'll be talking about swords device in configuration.
First, we're gonna talk about the stories, types a configuration. Then we're gonna talk about tearing
Roscoe. Talk about raid
and file system types.
This have some configurations that we have are removable media interface types, access fees, solid states. We also have USB drives and tapes. Removable media. First thing we have is this disk
awesome on its CDs, DVDs and Blue Race, Each one has their own stories capacity. Each one has their own uses.
CD is most time 700 mics
and their most the time used for transferring files from one computer to another computer. But with networking, CDs have gone out a lot and also with us. These CDs aren't as popular, either.
DVDs mainly used for movies now, and blue rays are mainly used for movies. Have a PlayStation. They do use blue race, and they only raise. So if any company wants to use blue race, they have to contact PlayStation to be able to use plea race
floppy disks. Floppy disks are pretty much obsolete Now, however, people still use floppy disks, most floppy disk and on Lee hold
floppy disk are still being used today to transfer small word documents from one computer to another and also a floppy. Disks are some of the primary means for
formatting a bios whenever it comes. So computer. We'll talk about that later, too.
USB DRIVES USB drives are replacing just about everything.
Why carry a CD that is fragile and you could break it? Well, maybe you could just load it onto a thumb drive and then take that wherever you need. I'm on top of that. A CD can only hold lessen the gig, whereas a thumb drive can hold. Sometimes up to 64 gigs are movable media. There's going to be fixed or removable
fixed. I mean, that is pretty much part of the PC.
You have to take something apart of the PC, takes something out of the PC to be able to remove it removable use maybe a USB drive or use a certain ports inside the motherboard. We'll talk about that later to interface types, the types of interface that we have our A t a I d say tha sas and scuzzy.
We talked about scuzzy a lot.
However, there is still a little bit left to talk about scuzzy
with advanced technology attachments. These are just particular ports that you use on your computer. They are actually fairly old, and most time they're also called paid a p a T A, which stands for parallel
advanced technology attachments
I de integrated Device electronics. All in idee is is the computer chip attached to ah, hard drive. This allows the computer to be able to access the hard drive with software that's provided with the hard drive without having to get additional software to use the hard drive itself.
Data serial 80 A. These air faster, and they are better than the regular A ta or P 88
status are also hot swappable. They're used on the motherboard and then the most common types. There are three different types. You have stayed a one C attitude and say the three
say the three can operate at six. Gigs say the two operates at three gigs, and Saito one is pretty much not used anymore.
Other thing we have is assess, which is SAS stands for serial attached, scuzzy serial attacks. Cozies are most commonly used inside of raids, and they're also used inside of servers. The scuzzy is how the motherboard communicates with the hard drive itself. Access speeds
with access fees you do have. Certain drives have certain speeds attached to them,
Leighton See is how slow something is. And then the access time is how long it takes to be able to access that
whenever it comes to a network, you want to be able to access the drives quickly. You want to be able to get to the position you want to be able to get to what you need. The information. You don't want to have to wait, so the access times is actually really important.
And the higher the Leighton see,
the worse your network will be. The soul will be. You'll be creating a bottleneck
and on a bottleneck is never a good thing. Whenever it comes to a network, whenever you need information,
the hardest species each drive has its own speed. However, there are particular ways that you can overcome those speeds.
As I mentioned earlier
say, the three runs at six gigs, however, you can run that faster if you raid them, and we'll talk about that later. Also,
solid state drives solid state drives were pretty much the fastest drives that we have out there.
are. They have no spinning parts, have no moving parts. A solid state drive has splashed modules on top of it
that allows it to be able to access information quickly. Solid state drives are a high performance device, however. The cost of sauce that drives it's pretty expensive. Most networks don't have very many solid state drives, and most companies that do implement solid state drives that have a sauce that drive for the operating system. And that's it.
They don't have programs loaded on that the programs were loaded onto an additional hard drive.
And, yes, ADA hard drive USB drives, USB drives our plug and play. They allow you to be able to plug into a PC without having a shut the computer down. We'll be able to plug a man while the computers turned on you. What, you need ejected drive and pull it out and go on your way.
Also, let's find a Dr letter in the O s If you ever notice when you plug in the USB drive and then you go to my computer, you're able to see what, Dr. You ever see the letter of it, and you're able to access it as if it's an actual drive.
The power that USB drives get is from the actual port itself. Some USB drives require external power.
They do require you to plug into the wall outlet to get a C power so that away they're able to use what they need to provide performance to the hard drive.
USB drives our best use with temporary transfers. They're not meant for a long term storage. USB drives shouldn't really be meat. Is it really a means to keep information for a long time? However, USB drive is a way to get information here and there, temporarily
transferring files from home to work. You can use a USB drive if needed,
tapes. The other thing. Other type of removal media. It's tapes.
Tapes are common way of storing backups. Tapes use magnetic strip there, just like with the VCR. Like whenever people used to use VCR, there's a black ribbon. That's what the information was stored on well, tapes utilize the same thing,
however, Takes a said primarily used for backups are used to create a monthly backup or yearly backup. Save it, take it to another site so that away, in case something happens on that site, they're able to get some of the information back.
Maybe there was a fire inside the building, and the fire burned up all the servers and burned up all the tapes that are locally.
Well, if those tapes are saved somewhere else on the different building or a different state, then they're able to access that information and they won't lose the information that they have. However, tapes they do have a slow seek time. You're limited to the device itself. You have to have a secondary device to be able to work with the tape itself.
Terry, we want to talk about the performance lab for each tear. And the policies that tearing has to do with tearing is split into four different tears. You have Tier one tier 22 or three in two or four
here. One is mission critical.
Missing critical things would be like performance capacity, reliability and management
with tear. One you have fast servers. You have large stories, pools. You have low latent see, and you also have
a large reliability and redundancy bought tolerance. When I write, come sit here one
most of time here. One is used when you need to have information given to you quickly.
Google, for example, would have tear one. Amazon would have tear one. Netflix would have to hear one.
It would use tear one to be able to give their customers what they need.
Here, too, is major business applications,
and he's very reliable and fast.
So with Tier two, they need to be able to get to their plate. They need to get what they need quickly, so speed is a little bit more important. However, the reliability of having the information there whenever they need it is also needed to two or three is for financial data. It's not access often, but whenever they need it,
that's where they really need to access it.
The information will be saved and sitting on the side, ready for the people whenever they need it. However, they won't be accessing it a lot. There won't be accessing that often, but whenever they need it, they need the information. Therefore, it's for storing email for long periods
you had used here four in a company where they need to access information. Every now and then, we're basically they have email safe or they have certain types of files safe, and they need to get to that stuff
roughly every now and then. But they don't have tohave it at all. I don't have to have it that often.
The next thing we have, its policies and policies are how you fit information into each one of the tears.
But it doesn't have to do with just fitting information. Each one, the tears. It also has to do with how the organization's gonna handle the data and how the customer is going to handle the data. You have something called a service license agreement Service license agreement is where you have an agreement between the two parties, the customer and the provider
of what they will be able to access, how they will access it, what they can store
and how often the information is available to them.
