WEBVTT 00:00.570 --> 00:08.790 When it's time for serious file and just general data storage we have to take a look at more robust 00:08.790 --> 00:11.650 methodologies and that's what this episode's all about. 00:11.820 --> 00:18.180 In this episode I want to talk about network attached storage and as Big Brother storage area networking. 00:18.210 --> 00:22.550 So both of these technologies are designed to store data. 00:22.560 --> 00:25.000 However they do it in very different ways. 00:25.050 --> 00:30.940 Now anybody who's ever used a computer is probably right clicked on a folder and shared it. 00:30.960 --> 00:33.100 And that type of stuff and that's great. 00:33.300 --> 00:39.960 But what I'm talking about is having dedicated systems dedicated systems that only share data. 00:39.960 --> 00:41.220 That's their only job. 00:41.250 --> 00:46.850 So sure I can take a Windows laptop and have it share all my critical company data. 00:46.860 --> 00:48.980 But there's reasons I don't want to do that. 00:49.080 --> 00:51.630 I want to use something that's more robust. 00:51.630 --> 00:58.730 So I want to be able to do stuff like put in a good RAID array and put it in solid backup methodologies 00:58.740 --> 01:00.370 and all that type of stuff. 01:00.510 --> 01:06.300 And that's really what we're talking about here so let's go and get started with the smaller of the 01:06.300 --> 01:08.800 two network attached storage. 01:13.360 --> 01:21.540 NHS is a file based sharing protocols so an NHS box itself has got to look something like this so they 01:21.570 --> 01:28.680 tend to be a smaller box and inside this box could be a bunch of raided drives whatever you might want 01:28.680 --> 01:28.980 to do. 01:28.980 --> 01:35.460 You might want to set that up and it's also usually running some type of very tight operating system. 01:35.460 --> 01:38.430 Linux is not at all uncommon for these types of boxes. 01:38.430 --> 01:46.530 OK so if we've got this box set up and if it's working at a file level that means that we will have 01:46.530 --> 01:49.140 to access this nest box. 01:49.140 --> 01:53.410 We will have to create the partitions or set set it up powered by B. 01:53.430 --> 01:58.680 We're going to have to format all the drives and then we're going to have to set up the NHS to share 01:58.680 --> 02:00.900 it via whatever protocol we want to share. 02:00.900 --> 02:07.440 So if it's Samba we're going to set up a samba share if it's Apple protocol we're going to set up an 02:07.440 --> 02:09.150 apple share whatever it might be. 02:09.150 --> 02:14.580 The important thing that you need to get in your head is that an NHS First of all it's got to run over 02:14.580 --> 02:16.680 your regular network so they run over Ethernet. 02:16.680 --> 02:17.490 Just great. 02:17.520 --> 02:22.950 They're going to be using TZP IP the whole shebang but they're going to be using well-known protocols 02:23.040 --> 02:27.540 and they will manifest as shares in your network just like anything else. 02:27.540 --> 02:29.820 So everything is done on the box. 02:29.820 --> 02:35.480 Now luckily for you I have a wonderful tool right here in front of me called Free and. 02:35.610 --> 02:42.930 I've went ahead and I got a system built up and I have a 2 terabyte hard drive that I'm currently sharing. 02:42.930 --> 02:44.940 So this is a free NHS. 02:44.940 --> 02:47.750 You'll see it actually has a web interface that's very convenient. 02:47.910 --> 02:50.010 And this guy is on my network. 02:50.010 --> 02:56.550 And what you'll see right now is I have created what they call a pool and this pool consists of exactly 02:56.550 --> 02:57.730 one hard drive. 02:57.990 --> 03:03.870 And then I've taken that hard drive and I split it up into two volumes and a volume and a say in volume. 03:03.870 --> 03:09.310 Now if you look at this you'll see 1.9 to be bits and 900 give me bits. 03:09.390 --> 03:10.170 Hey wait a minute. 03:10.230 --> 03:11.350 Isn't that more than two. 03:11.400 --> 03:12.390 That's right. 03:12.390 --> 03:15.360 These guys take advantage of compression tools and things like that. 03:15.450 --> 03:20.820 So they'll actually manifest larger capacity than the physical capacity of the drive itself so that's 03:20.820 --> 03:23.750 convenient is free as is called free NHS. 03:23.760 --> 03:29.160 But it's actually kind of like free NHS and essay end so we're going to hang on to the sand part for 03:29.160 --> 03:29.770 a minute. 03:29.790 --> 03:33.400 So even though it's called freeness it can really do both just fine. 03:33.540 --> 03:38.990 So it makes these volumes or I actually made these volumes pre-made them ready to go. 03:39.020 --> 03:41.850 Now what I need to do is then go about sharing them. 03:41.850 --> 03:45.320 So on this particular system I want to make a Windows share. 03:45.360 --> 03:48.980 So I'm going to come down here and let's take a look with shares I have. 03:49.020 --> 03:53.360 I don't have any right now so I'm going to add one. 03:53.390 --> 03:58.710 So first off I'm going to say what do I want to share. 03:58.880 --> 04:03.860 And the way I've configured this any volume it knows that I want to share it that way so I'm going to 04:03.860 --> 04:07.810 go ahead and say yes I want to share that and hit OK. 04:11.750 --> 04:12.830 I have to give it a sharing. 04:12.830 --> 04:13.560 There we go. 04:19.520 --> 04:21.770 So this is the volume. 04:21.770 --> 04:25.630 And then this is the actual Samba sharing that will show up on the network 04:31.120 --> 04:31.600 cool. 04:31.670 --> 04:37.700 So you can see that I have this share right now ready to rock and roll so the best thing I can do is 04:37.700 --> 04:44.200 actually show it to you and I'm going to do that simply by opening up my file explore on my system my 04:44.200 --> 04:45.710 messy messy file explore. 04:46.000 --> 04:47.620 I'm going to go down to network here. 04:53.270 --> 04:58.120 And we're going to give him a second because he's going to be scanning my network and let's see what 04:58.120 --> 04:58.660 he finds 05:01.910 --> 05:03.310 school right here do you see it. 05:03.320 --> 05:04.490 So here's a test. 05:04.500 --> 05:09.840 NASS So that's actually my next box or I'm going to double click on that. 05:10.060 --> 05:13.550 And there's the share that I just made. 05:13.590 --> 05:17.890 Now right now this is empty but I could go ahead and start putting stuff in taking stuff out. 05:17.940 --> 05:21.810 It's up to the free NHS tool to create proper permissions. 05:21.810 --> 05:25.760 Anything that I want for that in this case I left it wide open just so you could see it. 05:25.980 --> 05:27.930 But it works exactly like that. 05:27.930 --> 05:32.320 It just shows up as a share on my network. 05:32.370 --> 05:39.300 Now any guesses are very very popular specially for smaller networks for work groups that type of stuff 05:39.400 --> 05:41.080 that gives you a simple box. 05:41.160 --> 05:47.550 It works on top of your existing network in the road to the easy to use and they're very very powerful. 05:47.550 --> 05:58.080 However sometimes you need to take it up a click and in that case we go to storage area networks. 05:58.110 --> 06:04.800 Now if you want to get cool when it comes to data storage your best buddy is storage area networks or 06:04.800 --> 06:08.100 Sands now sains are big deals. 06:08.110 --> 06:16.510 A San relies on some kind of technology to transfer data between your system and the storage itself. 06:17.010 --> 06:18.850 Work at the block level. 06:18.870 --> 06:22.990 When we get this all set up you're not going to be seeing networked shares folks. 06:23.010 --> 06:27.590 You're going to be going into dismantlement and you get to see new hard drives that weren't there before. 06:27.600 --> 06:34.200 So sand's are very powerful for boot functionality for storing data all kinds of things like that. 06:34.380 --> 06:42.120 Sand's had been around for quite a while and the best sand's arguably ran on a type of technology called 06:42.360 --> 06:43.500 fiber channel. 06:43.560 --> 06:49.040 Now fiber channel has its own little network but not for the TZP IP stuff. 06:49.050 --> 06:55.440 It was just to move data around the fiber channel is still out there it's still pretty popular and it's 06:55.620 --> 07:01.170 wildly expensive so to make Fiber Channel work the first you'd have to do is plug a host busted Apter 07:01.500 --> 07:03.980 into your computer and you still keep your neck. 07:03.990 --> 07:05.760 You would need an HB. 07:06.210 --> 07:07.540 I don't have one on me. 07:07.590 --> 07:08.950 Here's a picture of one right here. 07:10.290 --> 07:17.220 So these HPH I mean they look like a fiber optic network card and they pretty much are but they're not 07:17.220 --> 07:20.250 running either and they're running their own language called fiber channel. 07:20.430 --> 07:25.950 So all these guys would run into a fiber channel switch and then the fiber channel switch would run 07:25.950 --> 07:30.690 to a fiber channel controller in a server room and then you'd have zillions and zillions of hard drives 07:30.690 --> 07:39.450 and they're all under the control of all this so a sans setup can and will easily cost you in the hundreds 07:39.450 --> 07:41.420 of thousands of dollars range. 07:41.460 --> 07:42.990 It's very very expensive. 07:42.990 --> 07:46.830 But boy oh boy is it powerful it is absolutely amazing. 07:46.830 --> 07:48.360 So I've just pulled up here on. 07:48.510 --> 07:53.460 I did a little google search on fiber channel and so you get an idea of the prices. 07:53.460 --> 08:00.590 These are just the little host adapters individually and there's a switch right there for you for only 08:00.590 --> 08:02.180 about $12000. 08:02.180 --> 08:06.890 Now what I want you to look here is you see Ritz's like 16 gigabyte 8 gigabyte. 08:06.890 --> 08:11.090 Those are the actual speeds that fiber channel runs at. 08:11.090 --> 08:16.490 So Fiber Channel came out originally like one gigabit per second which years ago was pretty fast. 08:16.640 --> 08:23.000 The cool part now is that we have a lot of Ethernet networks that can be running at around 10 gigs or 08:23.000 --> 08:23.900 something like that. 08:23.900 --> 08:29.750 So while Fiber Channel is still popular in fact Fiber Channel goes up to like 128 gigs now what we're 08:29.750 --> 08:38.390 seeing is a poor man's version of say in technology called I scuzzy I guess he basically uses your existing 08:38.390 --> 08:44.670 network and allows you to interconnect to different devices on top of your existing network. 08:44.810 --> 08:50.570 And it allows you to work at an ice block level so it's pretty powerful. 08:50.570 --> 08:57.900 So what I want to do right now is let's go back to Frean ass and actually set up a quick ice Gazi. 08:58.230 --> 08:58.790 OK. 08:59.060 --> 09:05.830 So here we are back in Frean ass and you'll see right here I've created what's called a SAN volume. 09:05.900 --> 09:11.540 Now that's a little bit of a misnomer here because one of the most powerful aspects of a Sam and something 09:11.540 --> 09:18.500 you cannot do with an NHS is let's say I've got a big pile of drives in my storage area all under the 09:18.500 --> 09:22.770 control of a say in what I can do is I can just cut a chunk of it out. 09:22.850 --> 09:23.670 Doesn't matter. 09:23.780 --> 09:25.370 I can adjust the size whatever I want. 09:25.370 --> 09:32.630 I'm going to go I'm going to get the this one for terabytes or whatever it might be it could be under 09:32.630 --> 09:33.260 rated. 09:33.320 --> 09:38.510 Beneath that everything's running but I can create what's known as an extent which basically says I'm 09:38.510 --> 09:45.140 going to cut this chunk o data storage out of my sand and then I'm going to give it to somebody else 09:45.140 --> 09:47.030 who will make it one of their hard drives. 09:47.030 --> 09:49.650 So I've really created a say in volume. 09:49.700 --> 09:55.380 You'll see it says 1.9 to be bytes available. 09:55.580 --> 10:00.030 But this guy I just happened to cut that much out of the harddrive. 10:00.050 --> 10:04.740 So what I'm going to do now is I'm going to go into Frean ass and I'm going to go ahead and connect 10:04.740 --> 10:04.880 it. 10:04.880 --> 10:14.080 Now before I do that what you have in any ICSE network is what we call a initiator and a target. 10:14.090 --> 10:18.110 So what we're going to do on the Free-Net side is we're going to create a target we're going to take 10:18.440 --> 10:21.610 that volume I created and we're going to make it a target. 10:21.740 --> 10:26.210 That target will get a basically a very specific ICSE type name. 10:26.210 --> 10:30.800 And then I'm going to go into my Windows system right on this computer right here and built into pretty 10:30.800 --> 10:36.330 much every operating system is what we call and I see as the initiator the I guess the initiator will 10:36.350 --> 10:42.710 go out look for targets and then go ahead and make it one of their hard drives so let's start off by 10:42.710 --> 10:51.060 making our target so just as a reminder we have our pre-made volume called the sand volume right now. 10:51.070 --> 10:55.110 What we need to do is first of all we're going to have to go through a couple of steps here. 10:55.210 --> 10:58.920 First of all we're after to make what we call the extent. 10:58.990 --> 11:01.050 So we're going to take a chunk of the standby. 11:01.060 --> 11:05.440 In fact I'm going to go and take the whole thing and I'm going to create an extent with some type of 11:05.440 --> 11:09.510 name then I'm going to create some type of target. 11:09.550 --> 11:15.190 So the target is going to in essence set up a lot of authentication issues in my setup. 11:15.190 --> 11:19.270 There really is no authentication so going to the target and then going to the extent that I'm going 11:19.260 --> 11:21.430 to put them together as a group. 11:21.430 --> 11:26.980 And once that happens they'll be offered up for anybody to access that has the right kind of permissions. 11:26.980 --> 11:27.330 All right. 11:27.340 --> 11:31.890 So to get all this happening we're going to have to head down here to ice Gazi. 11:32.140 --> 11:36.090 So the first thing I want to do is let's take a look at our targets. 11:36.090 --> 11:36.480 OK. 11:36.520 --> 11:38.400 Right now we don't have any targets. 11:38.410 --> 11:43.640 I'm going to add a target and I'm going to call the target share. 11:43.880 --> 11:52.490 And this is just authentication information that I had set up earlier and I can do all kinds of authentication 11:52.490 --> 11:56.660 stuff within I scuzzy But that's made all right. 11:56.750 --> 12:01.500 So the next hour I want to do is I want to go down to my extenso take a look at our extents. 12:01.640 --> 12:02.870 We don't have anything. 12:02.870 --> 12:08.170 So what I'm gonna do now is we're going to grab a chunk of that sand volume I made and I'm going to 12:08.170 --> 12:13.380 call him sand X T A and B. 12:14.760 --> 12:20.410 And you'll see that freeness has already seen that he's going to grab from that and I could change that 12:20.410 --> 12:25.550 if I wanted to and really has nothing else to do here other than just hit OK. 12:28.610 --> 12:31.060 So I've got my extent made and I got my target. 12:31.060 --> 12:34.980 I got to put them together. 12:35.110 --> 12:40.960 So my target extends I don't have any combinations right now so I'm going to pick my target which was 12:40.980 --> 12:47.000 share and then pick my extent which is an extent and I'm going to hit OK 12:50.560 --> 12:53.110 fantastic I think I've got everything set up right. 12:53.110 --> 12:58.000 Notice there is no partitioning or formatting here that's going to be done by the individual users. 12:58.000 --> 12:59.760 Once it connects to their systems. 12:59.920 --> 13:05.800 So let's go ahead and now we're going to try to open up the ice because the initiator on my system here 13:05.800 --> 13:07.280 and see if I can connect to it. 13:14.240 --> 13:18.870 So pretty much all operating systems have some form of ice as the initiator. 13:19.100 --> 13:24.790 And what I'm going to do first of all is I am going to look around and see if I can discover if there 13:24.800 --> 13:26.580 anybody out there doing ice gets it. 13:26.740 --> 13:34.320 Now I happen to know the IP address of my system and you notice it's running on port 30 60 and that 13:34.330 --> 13:35.110 filled in. 13:35.110 --> 13:36.210 I didn't get any errors. 13:36.220 --> 13:38.320 That's telling me I did a good job. 13:38.710 --> 13:40.700 So I'm going to go over to targets. 13:40.720 --> 13:43.140 And here is a scuzzy target. 13:43.150 --> 13:48.910 You'll see this is actually the nomenclature that's generated by ISKCON the colon and then whatever 13:48.910 --> 13:50.640 I decided to call the share itself. 13:50.800 --> 13:52.080 So I'm going to connect to it. 13:56.350 --> 14:01.510 And if I've done everything right we should be able to see something really cool in Device Manager 14:12.060 --> 14:19.530 sorry device manager disk management. 14:19.750 --> 14:21.500 And there it is right there. 14:21.640 --> 14:27.420 That is the extent on my scuzzy server that I've connected to. 14:27.580 --> 14:33.940 So you'll see that it's an formatted unpartitioned So I would have to go through all these processes 14:33.940 --> 14:38.470 of getting it formatted and partition and all that stuff. 14:42.280 --> 14:45.070 And this guy is pretty much ready to rock and roll. 14:45.310 --> 14:51.790 So for the exam the most important thing on what you remember is that network attached storage is going 14:51.790 --> 14:56.100 to be file level that's going to be some system running Linux or something like that. 14:56.140 --> 15:03.280 You go ahead you set up your RAID arrays you do your partitioning you do whatever you want to do format 15:03.280 --> 15:07.080 it and then they just treat everybody as network shares. 15:07.120 --> 15:09.700 It's going to be running Samba more than anything else. 15:09.700 --> 15:15.070 Sand's are a different animal sans run at the block level they're either going to be using fiber channel 15:15.250 --> 15:17.300 or they're going to be using ISKCON. 15:17.470 --> 15:23.440 And it's up to the individual targets to set themselves up and to partition and format as they deem 15:23.440 --> 15:24.790 themselves necessary. 15:24.790 --> 15:46.420 Oh and remember one more thing sand's are really really expensive and masses tend to be very very cheap.
