Video Description

This lesson focuses on enterprise storage and focuses on the following types:

  • Network Attached Storage (NAS)
  • Storage Area Network (SAN)

Video Transcription

00:04
all right, now that we've talked about virtual ization and we've talked about that across many different environments, whether it was a virtualized network of virtual server virtualized desk cop, we're going to now move into the idea of enterprise storage. So we're gonna talk about storing data
00:19
and obviously, you know, we have stored down on file servers traditionally.
00:25
But as our need increases for storage space for quick access to our data for means of replicating data across different environments, we may look additional storage solutions.
00:41
So the first storage solution we would look at is called in as a network attached
00:45
storage device. And it's exactly what it sounds like. It's essentially a storage appliance that resides on your network. That's essentially just a great big hard drive, except it's not great big. It's relatively small, but as faras storage capabilities, you know you might have a nap as appliance that stores in the terabytes of data.
01:04
Uh, its only purpose is file sharing and data storage. So there is no you know, there's a very, very low end operating system,
01:12
so that would be a means of lessening the attack surface. Sometimes you hear that term or lessening the attack footprint. You know, any time you have additional service is that aren't necessary. You have an increased attack for the footprint or increased attack surface.
01:30
So with the nasty vice storage of data zits on Lee concerned, the operating system has very, very minimal functionality.
01:37
It's correct. It's connected directly to the land, and it looks like a file server on the network. It'll have its own I P address and its own connective ity mechanisms. Certainly the advantage speed. You've got a large amount of storage space.
01:53
Uh, you have to consider that, you know, if you're putting all your storage files on one particular system,
02:00
that that might be an appealing target for a compromise, certainly. But the advantage is air, really just the increased speed performance. And in some ways it can really improve your security. It has less of a of a surface for attack.
02:15
Now a storage area network, high speed private network of storage devices, sand. So you've got multiple systems connected together. Now what? Essentially you have multiple physical hosts. Working together is a single logical entity.
02:31
So for me is an end user. All I know is I'm storing to the G Dr
02:36
for instance, Ah san is gonna look like just another hard drive on my local machine, and that's fine for the user. We would prefer for things to be a seamless as possible. The user doesn't have to know that we're sending to a separate network that does nothing but storage.
02:51
Now we would have to keep in mind for this network performance across the land. How are we gonna access this network?
02:58
What type of redundancy would we consider what type of storage devices are gonna be there? What sort of backup strategy and all those ideas? But it's another good solution for high speed access to storage.
03:09
There can be many different elements that are part of this network, whether it's hard driver. Rae's tape libraries, probably not, is frequent today's. Maybe they were a few years back, but again just looks like a regular hard drive. Ah, local hard drive to the users.
03:27
Now, if we do have a storage area network there a couple of different ways that we can connect fibre Channel I scuzzy and the now fibre channel over Ethernet. Traditionally, we've had Fibre channel, which fiber using high speed, uh, links to connect
03:44
to this remote network. If you will, uh, the benefit of that being very good speed, fast performance, the downside of that being cost. And I would have to upgrade some hardware and some network components and elements in order. Thio take advantage of fibre channel access.
04:01
So I scuzzy has been very popular. If we want to keep costs to a minimum and very frequently, we want to keep costs to a minimum
04:10
because the eye scuzzy is simply just extending the storage again. It kind of sits like it's a local hard drive, but it's just in a separate physical location. So ice, because he's gonna be able to take advantage of the current mechanisms you already have in place, you're not gonna have to upgrade your network components. You can use what's what's already there.
04:30
Now, Fibre channel over Ethernet kind of gives us the best of both worlds because we're gonna use our existing land environment.
04:36
But we're gonna bring in fiber for the high speed links to the, uh to the data storage for quick access and still keeping the costs relatively low. So that's becoming very, very popular as the cost of fiber goes down and the technology's improved, we're gonna really see fiber just continue to get more and more prevalent. So
04:56
fiber over Ethernet really has a lot of benefits that I scuzzy has what you get a little bit better speed.
