  • 0:00:22 So we're gonna take a look at the Cisco Interactive Catalog and specifically at the UCS server app.
    0:00:31 Now if you remember back to our Nexus Switching class, if you happen to be a part of that or watch those videos on demands, we took a look at the same application.
    0:00:39 And this is just from the iPad, specifically I don't believe it's available on android but then again I haven't checked.
    0:00:45 So it might be available now, but this is an application that you can download for free from the apple app store on iPad.
    0:00:53 And it's really nice, it lets you take a look in depth at a lot of the, well the high-end routers as well, such as the CRS that you see as the full rack routers as well.
    0:01:04 But the Nexus series switches and all of the UCS Server components.
    0:01:10 So we'll take a look first at the Blade Series Server.
    0:01:15 And really, the difference between these Chassis that you see here is, the one on the left is pictured without Fabric Interconnect.
    0:01:24 So the top and the one on the right is pictured with the Fabric Interconnects at the top.
    0:01:29 Now I realized some of you may be familiar and probably are quiet familiar with some of these hardware architecture.
    0:01:35 But I know that a lot of the people that are joining us have really never seen the UCS before and are wanting that hands-on experience
    0:01:42 and to know not only what the graphical user interface looks like and can do, and the command line but also really what is it that we're interacting with.
    0:01:52 What is it we're touching.
    0:01:54 So until you have the ability to get one of those UCS chassis, it's kind of nice to see what we're looking at.
    0:02:00 So we'll choose a Chassis and here we see the basic front view of the UCS blade series chassis.
    0:02:13 I'm not gonna click on all the little touch points, but you do have the ability in the app to click on anyone of the touch points and it brings up a dialog box at the bottom.
    0:02:23 So we can see here that we've got, and we'll just scroll in or zoom in really.
    0:02:30 We've got up here at the top, we've got a half-width B200 blade, M2.
    0:02:36 And the M2, that's the generation of blade that it is.
    0:02:39 So this is a 2nd generation blade.
    0:02:41 Below it, we have another half-width B230 blade.
    0:02:46 If we scroll over, we've got another B200 and another B230.
    0:02:52 We can then zoom out a little bit and we can see the bottom two really and by the way, I guess I should mention how ports are counted.
    0:03:04 So they're counted beginning at top left.
    0:03:06 So this top left up here is blade port 1 and then to the right is blade port 2,
    0:03:16 to the next bottom down where I just clicked on that red dot or orange dot however appears to you is blade 3 and then blade 4.
    0:03:24 So taking up the positions for blade 5 and 6 are the full-width blade and this happens to be, if I scroll in this is a B250.
    0:03:34 And then taking up positions for 7 and 8, we've got a B400 blade at the bottom.
    0:03:41 And then underneath that, we've got four power supplies.
    0:03:45 Okay? These are four single face, hot swappable, everything in the Chassis is hot swappable.
    0:03:49 The blades are hot swappable, the power supplies are hot swappable.
    0:03:53 If I switch it around to the back, the fans are hot swappable and the IO modules are hot swappable as well.
    0:04:02 So you see each of the eight fans here, four for each half and you see two Fabric interconnect.
    0:04:10 So if I take a look and zoom in over here, I see 8 ports on this.
    0:04:15 This happens to be the latest UCS 2208 XP as we can see about the port number up there, Fabric interconnect and those are eight 10gigabit Ethernet ports.
    0:04:27 We'll talk about in the next section, what those ports can do in terms of uplink capacity and capability,
    0:04:34 and then also what the downlink or southbound facing to the blade capacity of each of these are.
    0:04:41 But that was Fabric interconnect 1 and then here we have Fabric interconnect 2.
    0:04:46 And these go to, I'm sorry, I'm saying Fabric interconnect.
    0:04:50 These are the IO modules are FEXes, so forgive me if I misspoke there.
    0:04:54 These are the IO modules, they're not the fabric interconnect, so I misspoke.
    0:04:59 But these go to fabric interconnect 1 and 2, or Fabric interconnect A and B.
    0:05:06 Okay? So if we take a look, we can pop out anyone of those IO modules FEXes.
    0:05:23 And the animation actually, there we go, I thought I was gonna spin the whole thing around.
    0:05:27 So again this is the IO module or FEX and we can see all of its back plane connections.
    0:05:35 The 22A, 2208 happens to have 32, 10 gigabit Ethernet back plane, 10 based, sorry 10 based KR back plane Ethernet connections.
    0:05:47 And then it has 8gigabt Ethernet uplink connections.
    0:05:50 We'll talk about where those go in just a moment.
    0:05:55 So that's FEX 1.
    0:05:58 If we want, we can take a look at the actual 6248 Fabric interconnect.
    0:06:06 And I was looking for a picture of it just by itself, there we go.
    0:06:15 So we'll pop this IO module back into the Chassis and spin the box around and take a look just at the Fabric interconnects added.
    0:06:25 So one of the things that you note is how the, how they orient these fabric interconnects.
    0:06:33 And actually let me make a note just about the Chassis itself.
    0:06:36 This is actually a really deep, and it isn't necessarily anything you have to know for the exam.
    0:06:41 You're not gonna be touching the hardware.
    0:06:44 In fact you have no access to touch the hardware, but it's just good to know for whenever you do get your first one and put it in,
    0:06:50 they say that these handles are not for actually picking it up, but they're just for moving it back and forth in the rack which I find a bit impractical.
    0:06:58 But as long as you empty out that Chassis of all of its blades, all of its fans, and its IO modules, then you, I have used them before but again Cisco said you should not use the handles.
    0:07:11 The chassis itself is about 100 pounds empty.
    0:07:18 So it's actually I think it's about 90 some pounds without any of the blades fans or IO modules.
    0:07:24 So it's a fairly heavy device.
    0:07:26 It's also a 6-rack unit device, 6RU.
    0:07:30 So you can actually fit in a standard 72 RU rack, you can fit 7 of these chassis or 6 Chassis if you're adding the Fabric interconnects at the top.
    0:07:42 So each of the fabric interconnects have dual power and this is actually showing two separate fabric interconnects.
    0:07:48 Because you would always provision a blade system with two.
    0:07:55 One of the things that we saw in the diagram is we saw those two 1gigabit Ethernet connections between the fabric interconnects that I said were for management and data,
    0:08:06 I'm sorry, management and control plane only, no data passes through those.
    0:08:12 And those are connected L1 to L1, and L2 to L2.
    0:08:18 So this is the only place in the system that the two fabric interconnect are connected together.
    0:08:25 L1 to L1, L2 to L2, not L1 to L2 and vice versa.
    0:08:32 And then we have a management 1 gigabit Ethernet link on each FI or Fabric interconnect as well that we would uplink to our management network of course.
    0:08:45 And in our rack, we don't have that pictured on the physical or logical topology.
    0:08:50 But we do have each of our devices with their management port to a basically an out of band 3560 switch.
    0:08:59 And then we also have a console connection and we do have an access server or terminal server,
    0:09:05 however you like to refer to it, connected to the console session of each of these Fabric interconnects.
    0:09:11 And that's how we'll be looking at the command line.
    0:09:14 You can SSH into them as well, but it makes more sense to connect to them through the console because we never have to worry about connectivity loss.
    0:09:24 So here we can see the Fabric interconnects up close.
    0:09:28 And each of these are the 6248 unified port, meaning that they, anyone of the ports can be either Ethernet or fiber channel.
    0:09:38 And if you remember back to the storage class that Brian taught in the same way that you had to choose, you had to basically split the switch into Ethernet and fiber channel based on the port asic.
    0:09:53 So you could only split them on a port asic boundary.
    0:10:00 And you basically took the upper half of the switch or the upper third of the switch or however many ports you wanted, but they were at the upper side of all the port count.
    0:10:09 And those became fiber channel and then the lower side became Ethernet.
    0:10:14 And wherever you split that on the port asic, below that split was Ethernet and above it was fiber channel.
    0:10:20 The same goes for the fabric interconnects.
    0:10:23 And you're gonna see, that's gonna be one of the first things that we do in connectivity because it's going to, just like the Nexus 5K, it's gonna require a reboot of each fabric interconnect.
    0:10:33 So we also have GEMS or, and I'm not talking about the 1980's TV show Gem, but it's spelled the same way.
    0:10:44 Generic Expansion Modules.
    0:10:47 So we have either 124 or 8Gig fiber channel or 1 or 10Gig Ethernet ports.
    0:10:57 And again, these are unified ports, actually it depends on the Generic Expansion Module that you get for the 6248 UP or Unified Port.
    0:11:06 They are also Unified Ports.
    0:11:09 And these are actually independent.
    0:11:10 There's actually, they have their own operating system or really sub OS and their own sub power supply.
    0:11:18 So actually you can reboot one of those Generic Expansion Modules in an FI without rebooting the entire FI.
    0:11:27 So that's a nice feature.
    0:11:28 If we take a look, we can see the actual wiring.
    0:11:41 And that was, there we go.
    0:11:44 So here, we can see that we've got IO module 1 on the left with four 10Gig Ethernet uplinks to FI 1 only.
    0:11:53 And then, not that you wouldn't probably use the same ports, you probably would.
    0:11:59 But just for the sake of clarity on their animation, they put FI 2 or FI B, Fabric interconnects B to IO module B on different ports.
    0:12:12 But you would typically use the same port numbers and certainly we will, and you can see that from our diagram.
    0:12:19 So this is just an example of linking them up.
    0:12:22 One of the things to note is that, while on the back of the, and these are actually older, these are actually older fabric interconnect 6120's.
    0:12:34 Where L1 and L2 are on the front or maybe I guess you could call it the back, depends on how you wanna look at it.
    0:12:42 Earlier when we looked at the newer 6248 UP's, they were on one side and all of the 10 Gigabit Ethernet connections were on the other side.
    0:12:51 But again, there's no data plane connectivity between these.
    0:12:55 In terms of just a view of scalability, here's just an example of one pair of fabric interconnects managing up to, in this picture, 40 Chassis.
    0:13:05 Again it depends on the model of fabric interconnect and that's all we will be taking a look at next.
    0:13:10 But the scalability is tremendous of these systems, especially when you factor in the amount of virtual machines that you can run on these extremely powerful and extremely memory dense blades.
    0:13:26 So next, let's go ahead and remove a blade.
    0:13:30 So let's remove a B200 blade from a single chassis and take a look and see what that, those blades look like.
    0:13:38 So this is going to be one of the half-width blades.
    0:13:43 And this is actually a very long blade.
    0:13:45 The picture is a little bit deceptive.
    0:13:49 And what the animation just did was, and if I can turn this just the right way, I'll swing it back around.
    0:14:00 It, let's see if I can spin this the way I want it, we'll maybe I can't
    0:14:06 I'll just do it like this.
    0:14:08 Here's the front of the blade and we see that we have hard drive connectors.
    0:14:11 Also, one of the things to point out is that we've got a console connector here on the front.
    0:14:16 If you have the console connector here on the front active, then you certainly have full console capabilities directly to the individual blade.
    0:14:29 Okay? But you, again, the way we'll be doing it throughout the class is through KVM over IP.
    0:14:36 And probably the way most people do it.
    0:14:38 So we also have our DIM slots on this particular blade.
    0:14:42 We have six DDR3 memory slots and we have two processor slots, each of these processors, we'll see how many cores they can take.
    0:14:54 But one of the things the animation just did was, it removed as we can see here the Virtual Interface Card or the Converged Network Adapter.
    0:15:05 Now, I keep saying Converged Network Adapter or Virtual Interface Card, I'll talk about what the differences are between these.
    0:15:11 Cisco likes to say that their Virtual Interface Card is really the next generation of CNA.
    0:15:18 But it is still the CNA, it is still the Converged Network Adapter in the sense that it still converges Fiber Channel
    0:15:24 encapsulates that in the Ethernet protocol and sends both out over 10 based KR, or back plane Ethernet.
    0:15:33 Okay? But the Cisco's Virtual Interface Card does have far more tremendous power and capability.
    0:15:40 So this is just an example of a Blade.
    0:15:42 We'll go ahead and also just show a, let's just show a full-width Blade.
    0:15:47 So that was a half-width Blade that we will put the cover back on, which just slides to the back.
    0:15:54 And we'll put that back in the Chassis and we'll grab out a full-width Blade.
    0:16:03 And when we pull the Chassis off, we can see the two Converged Network Adapters or two VIC cards removed.
    0:16:11 And we can see the capability for four processor slots here, and quite a tremendous amount of RAM.
    0:16:32 Here's an example of just a VIC 1280, which is the newest Converged Network Adapter or what we'll call Palo card from Cisco.
    0:16:55 And there's really now a lot to look at here but again, this is the newest card from Cisco and it's got tremendous capability.
    0:17:03 It has the ability to create some concept that we haven't introduced yet.
    0:17:08 Something called Virtual NICs and Virtual HBA's.
    0:17:12 Really the way that the entire UCS sub Blade Series works.
    0:17:16 But it has the ability to create up to 256 of these.
    0:17:20 Now, you have to choose between V-NICs and V-HBA's.
    0:17:24 The amount of V-NICs and V-HBA count has to do with how many uplinks from the IO modules to the Fabric interconnects that you have.
    0:17:33 So you can't just create all 256 V-NICs or V-HBAs, or combination of the two to equal, no greater than maximum of 256.
    0:17:46 But you can't just create those without having all eight ports from each IO modules uplinked to the Fabric interconnects.
    0:17:58 And actually, one of the thing that I didn't mention, that I'm just going to show here again real briefly,
    0:18:05 is on the wiring, while this is being put away, of the IO modules to the fabric interconnects, there's a strict wiring requirement that you can't violate.
    0:18:19 And we're gonna talk about what that is, based on which IO modules you have.
    0:18:25 First of all, there's two main port density for uplink of IO module to FI.
    0:18:32 And that is either four ports or eight ports.
    0:18:35 And then there's also the Gen 1 four port, which is the 2104XP and then there's the Gen 2 four port, which is the 2204XP.
    0:18:46 And here, you're seeing the Gen 2 eight port which is the 2208XP.
    0:18:52 And you can only uplink either one port, two ports, four ports, or eight ports.
    0:19:00 And if you uplink them, you have to do the same number on each IO module to FI, or Fabric interconnect.
    0:19:07 So I could not do, let's say three ports on either of them.
    0:19:13 I also couldn't do two ports on one of them and four ports on the other.
    0:19:18 It's not really that I would even want to, but let's just say I would short of cables but I wanted to try to squeeze a little bit of extra bandwidth of that with one of them.
    0:19:25 That's not a supported architecture.
    0:19:28 And in the next, the next section, we're gonna talk about why that is when we talk about how the uplinks from the IO modules to,
    0:19:39 or really actually from the Blade converged network adapters to the IO modules, how that works.
    0:19:46 That's when, that will make sense why we can only have one, two, four or eight.
    0:19:53 But again, that's the only supported combination.
    0:19:57 So we'll take a brief look at the C200, I'm sorry, well yeah, we'll take a look at the C200,
    0:20:01 but the rack mount series, you can see that there's a number of rack mount options available.
    0:20:12 And if we take a look at the insides of these, you've probably seen standard rack mount servers.
    0:20:22 So there's really probably nothing too spectacular here.
    0:20:26 In fact, maybe one of the only really interesting things about this is, some of the more powerful systems where we have a lot of disk drives available.
    0:20:37 One of them even supports up to 24 disks, or even some of the memory architectures in here where we've got tremendous,
    0:20:47 all of those things on either side of the processor core or processor slots are memory banks.
    0:20:53 We've just got tremendous amounts of internal memory and density of memory that we can use on these C Series Rack Servers.
    0:21:06 Okay? So this will probably conclude just looking at the actual hardware.
    0:21:10 If there's any other thing that anyone wanted to see before we finish out with this, and I switch back to my other machine and other frame rate.
    0:21:21 Then, someone asked the question: Do we use crossover Ethernet cables for L1 and L1, and L2 to L2?
    0:21:31 No, we do not. Standard straight-through cabling.
    0:21:35 Good question.
    0:21:38 Someone asked the question: How many links do we have to connect between the IO modules and the fabric interconnects?
    0:21:44 So hopefully you just saw how many links we have available, which is a maximum of 8 gigabit links, sorry eight 10 gigabit Ethernet links.
    0:21:55 And so, that does give us the ability with the new gen. 2 with the older generation 1, the 61, I'm sorry the 2104XP.
    0:22:07 We could not do port channeling.
    0:22:09 With the gen.2, the 2204 and the 2208, we can do port channeling.
    0:22:14 And we'll talk about how when we might want to do port channeling, and sometimes we might not want to.
    0:22:19 But we'll talk about that later, but with port channeling, and let me just go ahead and bring this up while I'm talking about it since it's relevant.
    0:22:27 But with port channeling, what this is giving us is, it might seem like we have the ability to have 80 gigabit per second.
    0:22:40 And here we've got a picture of all 8 links on both IO modules to both fabric interconnects.
    0:22:48 It might seem like we have 80 gigabit per second because we know that we're only going up to one of the two fabric interconnects from each IO module.
    0:22:58 But in fact, we do have the ability depending on how we're sending traffic out of our converged network adapter or virtual interface card, or VIC cards.
    0:23:10 Depending on how we're sending traffic out, we have the ability to send traffic out both IO modules at the same time to both fabric interconnects
    0:23:20 and then they can send those upstream to the upstream LAN switch.
    0:23:25 So both IO, both fabric interconnects are forwarding both IO modules are forwarding at the same time.
    0:23:35 From a management and control plane perspective, only one FI at a time is active and the other is in standby.
    0:23:43 But that's simply or explicitly just for management and control.
    0:23:51 For data plane traffic, both fabric interconnects are active and forwarding.
    0:23:57 And again, think about it, they look just like two hosts to the upstream switch.
    0:24:02 And if we're using VPC mode, on the upstream switches, then it basically looks like we have one host with two network cards connected to a single upstream switch.
    0:24:13 And so, as long as that network card knows how to actively load balance traffic up cross both links, and something like ESXI4 or ESXI5 handles that famously,
    0:24:28 then we have really 160 gigabit per second out of each Chassis out up to the fabric interconnects.
    0:24:37 Here, we're showing 6248 UP's.
    0:24:40 So this is 48 ports of full-duplex, non-blocking line rate 10 gigabit Ethernet.
    0:24:47 But we also have the ability; we'll take a look at the next section at the specs to implement 6296's.
    0:24:55 So Cisco does have 96 port fabric interconnects as well.
    0:25:01 Obviously we can't have 20 Chassis, each with 8 gigabit or sorry, eight 10 gigE links from each IO module and still be able to support 20 chassis on a 96 port FI.
    0:25:17 So there does have to be some talk about, do you want to oversubscribe your fabric interconnects.
    0:25:26 Do you want to not necessarily have all links populated, or do you wanna simply have more UCS domains,
    0:25:32 and you buy more fabric interconnects to run more UCS domains.
    0:25:37 And you are actually forwarding at the full 80 or 160 gigabit Ethernet uplinks.
    0:25:48 We're gonna talk about that next.
    0:25:49 Someone asked the question: How do the interfaces on the IO modules correspond to the blades?
    0:25:53 We're gonna talk about that next.
    0:25:58 I need my tablet back to be able to draw that out.
    0:26:04 Someone asked: What is this app again?
    0:26:06 This app is called the UCS, I'm sorry, not UCS.
    0:26:10 It's called the Cisco 3D Interactive Catalog on the iPad.
    0:26:18 Someone just asked the question: Which are the uplink interfaces on the FI?
    0:26:23 That's a good question. I'll bring this back up.
    0:26:26 But the easy answer is, whichever ones you want to be uplink interfaces.
    0:26:32 So we actually have the ability with the 6248 to specify.
    0:26:38 In fact, it's not just an ability, it's something that we're required to do really to denote when we first provision our UCS manager system.
    0:26:48 And it is disruptive, but again, it's something you would only do when you’re first provisioning the system as you're adding chassis on later.
    0:26:54 Hopefully you've planned out everything very well, in fact that's going to be one of the things that we're gonna talk about.
    0:27:00 Not only, which it is related to the lab exam but also to real life, is how much preplanning you need to do before you go
    0:27:08 and actually implement just about anything on the UCS manager unless you're displaying around with it for the first time.
    0:27:15 But it's a really good idea to have planned out exactly how many chassis you hope to grow to.
    0:27:20 I realized that can't always be accurately predicted and so there will be times of maintenance and down time and changing port modes.
    0:27:32 But you can on an individual port mode, change what its function is.
    0:27:38 So we can say that, for instance, and I can't really do a mouse over but we can say that port 1 here is a server port.
    0:27:46 And if we say it's a server port, that goes down to the IO module and down to the Chassis.
    0:27:51 Port 2, 3, 4, those are all server ports going down to the IO module and down to the blades.
    0:27:57 Then I can say port 5 and 6 are more server ports going to maybe another chassi.
    0:28:04 And that's the way we'll be running it in our lab.
    0:28:06 Ports 7 and 8, 9 and 10 will be uplinks, two 10Gig Ethernet uplinks to 5K 1 and two 10Gig Ethernet uplinks to 5K 2.
    0:28:18 And that's how we have ours configured or will actually.
    0:28:20 We'll be provisioning it from the ground up.
    0:28:22 So it will be basically empty when we take a look at it.
    0:28:25 And then 11 and 12, will be fiber channel, fiber channel native, fiber channel ports.
    0:28:34 And so that means that from 11 and 12, all the way on up to by default what comes in is 32 ports.
    0:28:42 And then of course we have the expansion module that we can add.
    0:28:46 But if we don't purchase an expansion module, then from ports 11 and 12 up to 32 on each FI will be native fiber channel.
    0:28:56 Now, I should also mention something really not particularly related to the lab,
    0:29:00 because you won't have to or at least you won't have to worry about paying for the licensing of this.
    0:29:07 You may have to install or change the license but that's really trivial.
    0:29:13 Is the fact that the licensing port count?
    0:29:15 So on the FI's and for those of you not familiar with this, you might be aghast at this.
    0:29:22 But it's nevertheless the case on the fabric interconnect, Cisco charges per port.
    0:29:28 So it doesn't matter that you actually have 32 ports, you can't use them.
    0:29:31 Well, you can for the 120-day grace period, but then you have to buy a license for each port.
    0:29:37 Now, by default when you buy an FI and Cisco will only sell you a pair of FI's, you should only buy them in pairs anyhow.
    0:29:44 You get 12 ports licensed.
    0:29:47 So it comes with the first 12 ports right from the factory.
    0:29:51 But after that, if you want ports 13 through 32 lit up, then you have to pay for the port license.
    0:30:01 So that's something to keep in mind.
    0:30:05 Someone asked the question: So one of the FI's will be active and the other will be standby or can they both be active?
    0:30:11 I wanna be clear on this, from management and control plane perspective, only one is active and the other is in standby mode.
    0:30:20 From a data plane and by data plane, I mean both Fiber channel and Ethernet; they are both active and forwarding all the time.
    0:30:28 So we do truly have, if I just had a single chassis, and that single chassis had 8Gig or sorry, eight 10Gig E uplinks from each IO module,
    0:30:41 then that means each chassi has 160 Gigabits of uplink active, both IO modules, both fabric interconnects are active for data plane.
