MASSIVE SWITCH! - What's Inside the Cisco Catalyst 9600?

[Music] what's going on guys welcome back to this is IT we're gonna talk about something new that Cisco's coming out with the catalyst 9k which mount might sound a little weird if you have heard of catalyst but we have Rajesh here and he is kind of the architect but I'll let you speak for yourself Rajesh tell us about yourself and yeah hey folks I'm Rajesh I'm a principal engineer in the switching hardware and systems group in Cisco this is the new catalyst 9600 so I mean it the switch looks really cool I mean can you show us a bit about like the internals or like what she thinks really cool about this yeah so maybe let me start with the exteriors first yeah go for it it's a pretty small about for the bandwidth and the capacity which you can support and if you look at the chassis by itself so it's a six swap system so you can you can see the rock numbers are marked up in the front or the factory so what are these 6500 half so it's all one thing which is carried forward from the 6500 is the overall appearance of the chassis in terms of its simplicity and how the cards and cooling and power supply is all linked together into one platform so very similar to 6500 e to say site to find airflow system and the fan to a six on the left side of the chassis it's three by three array of fans which hold this system and basically each row handles two slots in the chassis if you can look at how it aligns oh yes now and you can take it from the back of the front right yeah and the full feature of this chance is that Fanta can be extracted from either from the front over the back that's cool why did you guys design that I've heard there was like a clever reason why you yeah one of the reasons why that is very important is it depends on how you cable out the interfaces which is there on the system if you look at it you would want to like when you plug in the optics or the copper the cables which I need to point into each of the line cards you would want to make it go out evenly on right and left and if you come out on the left side you find ray so in order to overcome that having it accessible from the rear makes it makes a lot of sense but now I have to know and I don't know if your maybe you were part of that team but how did how did like a company that designs cars design a switch um some of the inputs which they would like us to use cannot be actually being executed in practice some of things which are pretty cool which they had passenger is some for example how the curvature of a of these the folds of the sheet metals are done it's amazing if you know some legacy for example if you look at 6500 for example it's dumb the each of the sheet metal plate they are riveted together and they respond that's wrong right and square edges and if you look here for example if you just look at the front of the chassis you don't find any rivet in the front this is one cool feature no earlier we would have hand not to ensure the mechanical stability of this you would have had it's all over the place and you covered you would even even end up having rivets form the logo itself and if you look at it so inner so these these are the extra ones which compensate for the ones which we to count on the top of the chassis okay yet it looks I mean you wouldn't say pretty switch but it is pretty it's not like a typical I guess he liked 6500 it was like like an industrial thing yeah I want to say David I wanna hear you say it's a sexy foot I'm Lauren come and say it now other thing which are in fine a holistic design well are the car detectors if you look at how sculpted the handles are each of these laborers and how they how user-friendly they are this is something totally new oh it's a two hand thing I want to feel this emotion exclusives you're already invited so when some of the comments which you bought from customers is that yeah handles they are they feel sturdy yeah whereas in the past they used to have something but just need to work more than that so it's not just in Austria yeah and so the other things which you do whatever you like it's brilliant and you can see how very cool so I mean that's the outside what can you tell us about the yeah I can't oh that's going good so so the middle those lots are where the supervisor or what is traditionally called the soups so you said that again the two middle slots yeah yeah the two middle starters is three and four on the 6500 was it wasn't it at the top cause it was in the middle II actually 6,500 are a lot of legacy but the very earlier versions of it did support a supervisor on the upper slot but eventually all the implementations and in the center they say left a good reason for it what's gonna watch it was Rihanna so the reason is to have it evenly spread out of the connection to the line cause they're symmetrical you equalize the length right so if you had a supervisor on the top and so the the the card which is furthest away from my there are four more losses yeah so you would want to keep it as low as possible and it's also very symmetrical so that the implementation is easier yeah so if I did it's beautiful that's the right word no no no sorry go on David's having a moment you might want to take it all this time with David okay so the main things which you see on the supervisor are the three new ADP Asics which sit very close to the backplane which is this is the first a six second a second and third ASIC and the remaining big heat sink which you see over here it is the CPU and the CPU with its memory and with its storage so these form the critical major component which can see which one's the storage this is a storage which can be used for applications any basis t cottage is the slot is the location for instance of this particular module I have here is showing a blank yeah which you take it out and destroy with it so you can have a dust in your switch that's what it's for storing application metadata like it can be an additional application which you could run on on the CPU on the supervisor in addition to the iOS which runs to run the switch and platform oh wow I heard you could run like docker containers or something like that yes that's really me one really one so can you just explain for people who are not familiar with switches what is it what if what isn't ASIC or what are these things so I probably need to go to something more basic in a sense like a 9600 uses a centralized forwarding architecture which means that you the forwarding decisions are not actually done on the lion guard oh that's very different that's very solarek this is all the switching is done on the supervisor so the intelligence is here all the entry on the forwarding intelligence are being in the supervisor and these are the devices or the Asics which will implement all the packet forwarding features for the system so on the line cards can you show what it shows what the line code looks like the line card it has just front panel optics which on to which you can connect one gauge can gauge 25 high-speed optics which are needed for all the Eastern interfaces and the physical layer devices so what seats underneath these seats things are the physical i/o devices and beyond that just connects into the backplane and goes over there so if I understand right if you had like the line code here I mean so let's say line cut yeah yeah the line coach here if traffic needs to go say from a poor chair to a poor chair does it go all the way to the supervisors oh yes so the way the traffic would have for example if you take any two ports here yeah if you're on the same line caught it on the even similar so the traffic would go through the finite physical layer devices and it will enter the supervisor probably let's see if we take a port on this side of the line card yes it will end up on to this a sink and if the destination port happens to be a port which is on this side it will traverse through this much of the lasix arrive at the ego's asic where it needs to get out and come back all the way to the back playing into the 5-11 commodity so wide is a reason why you went from distributed to centralized architecture this architecture will get you simplicity yeah and if you look at the line card if you make the line card absolutely simple right and the software implementation is also simplified just by having all the forwarding located on the supervisor because in the old days I mean Chuck and I were talking about this the other day you would have to run IO like an image on the line cards and this say yeah and if you have to upgrade it's a it's a nightmare so this simplifies it simplifies it yes so so the story for is iss-you I mean that will improve and what about speed I mean you don't have to give us figures but like you general if I wasn't it quicker to just move from here to here on the line card instead of going all the way to the device that is connected so if you look at it just from the packet flow perspective yes that would have been a low latency path I mean it's so fast isn't it because I mean these things are like you can go a hundred gig on this is negligible like you know like relying speed is it yeah yes so in other words to answer the crazy my own question it's if there's no like delay even going to the supervised and coming back it doesn't slow the line breakdown is that right I just understood in the past one of the reasons that they did distributed architecture was supposedly if I understand right is that if you moved from one port to another on the same line code it was quicker than sending it up to the supervisor was that like is that incorrect doctors I mean I wouldn't say that is not correct but um distribute architecture is that it will scale better but if you look at the centralized architecture you are actually limited eventually by what does a six on the supervisor can do and here and what the the greatest advantage of centralized switching is that each will get you in a dispute system you would have had more hardware to make the decay to that scale which is actually a feature profile so you would have more hardware and you might even have a forwarding ASIC sitting here making a decision as to all this packet is actually it is time to be another port on same card and it has to make a decision which is send it back on this board right so that decision requires extra hardware and ASIC to sit on the bank on if I understand right like today these line cards here if you put a hundred gig in here this one would be disabled because that's a limitation of the of these supervisors a limitation but when you upgrade the supervisor then in the future you would get that yeah yeah the line card can last much for generations of the of this system by upgrading your supervisor you would certainly have more features for more speeds and more bandwidth which which are not possible earlier so what do you what do you find exciting about this switch compared to like previous generations I mean is there any specific feature that you really like like proud about all excited about like when you guys finished it you're like yes yeah so there is one cool feature which is actually implemented in the layer one device so that that's what makes the line card very unique devices the I used a very simple term I simply said it's a PI or the physical layer device yeah what is that it's a bit more than that even though the eventual function of the device is still by layer it doesn't look at what packets are flowing but it has this feature of being able to talk to two planes or forwarding engines so one thing I didn't talk about earlier is that you could have written and supervisor right so so the the supervisor which is to come from start fourth it could be another supervisor and slot three and they work together to form a hot standby system yeah now the fine layer device on the line card has this unique feature which is which we call internally as a hitless marks which me which would make a decision as to which we forwarding plane it extracts the package from oh wow so so and in the equal direction it knows which of the supervisor is active and it only takes out the packets which are coming on from that supervisor going out the physical interface in this way and on the increase direction it actually replicates back is going to both forwarding planes so that helps improving the sign for the system so for example is when you have I have ability even like a supervisor field over the cut over time for rebuilding all the interfaces and routes is much faster than what was happening earlier with the distributor so how fast without it's a 64 that's amazing and and because of this packet replication and the egress decision which is done only on a five layer device um when a switch or happens that is when you cut over from one supervisor other yeah the drops are very very tiny that's been so in theory we should be able to get just only one packet drop per that's something unprecedented than what was done before so when I cut or what happens usually you would get much higher drops like usually in the hundreds of milliseconds and then the control plane to take over itself take addition also used to converge probably so super in perspective like what what kind of application would be affected by that failover where it would be a bad thing and why I was doing this gonna fix that that'd be a voice or what it feels like the one supervisor dies yes so that that's one scenario but the other scenario which is more realistic is a upgrade of software on the system so when you are upgrading the software the you are basically cutting over from one to the other so so you basically upgrade software on this time by and then you've cut over to that and then you pick up the other one right so you're that cut over would have cost you a lot of traffic drop which is minimized by this so that's how I mean it's really cool it you don't have to upgrade the line cards and then you have this like small window when you upgrade the supervisors yeah that's brilliant so that's like one of the features you really product yeah yeah that's good again that's a message yeah yeah really a lot of effort to get that to work correctly one thing so one of the challenges which we have in older newer systems [Music] yeah but heating stuff switching yeah so if you look at done supervisor you see this have to heat things on the Asics yeah so if you if you looked at an all your system yeah you put in taxi in such large heat sinks and and so some of the cool aspects of the arm heat sinks are these are all vapor chamber he thinks if you looks like this because the bottoms are this like for example this this particular one right if you look underneath it you can see this this pipe it would basically to say one being so it is some liquid inside liquid cooling your switch it does I should I don't want to say you already did but this liquid cooling would usually I mean when we say liquid cooling it usually in all and closed-loop interface letting you actually plumb and you have a really clearly everything yeah so you would have a complete closed-loop it a something where heat is extracted and you push out to an exchanger or where you check out the heat right yeah so in that way this is not really equivalent because everything's built into it and when I say liquid is just a which way prices and changes phase and extract the heat from the center and bring it out to the fins right that's intense so one thing you would make this something you should physically hold it in your hands hold this one and you whole you think you can feel that's a difference there that's a yeah so everyone knows this is that that one is much heavier yeah all right so this is I feel like you look really well let's look at Charles toy yeah that's crazy much different level all the secretive things like this wow she's only get the closer look at the so these are little pipes you said yeah that's actually dumb okay are you saying it's like going through a whole process of evaporating and I think you can look like it's quite a vapor chamber he thinks okay now it's just like the first product you guys had that actually has this feature um there's not exactly the first one to be I've had a few 500 and as if you the one other problem here is that you have three a six and because the air flow is site designed from right to left does if you look here it from here to here yeah the heat produced by this is going to heat up this one so it's more it's getting more and more to here so now we are not able to get away without having those that's pretty cool so that is one thing and then the other thing which I want to bring up this system so these connected systems are future proof to support higher bandwidths as we go generations into the life of this platform if we can upgrade which supervisor up case with Lanka or future support higher speed interfaces so right now the lion car that you have our one hundred gay but in the future for not take is also she wouldn't have to create even after prices you wouldn't have to upgrade that chassis because the infrastructure or the the backplane of the chassis already has that can we go I mean you can see that they are hefty and for that sauce one is a future-proof for delivering power into the comment I'll say like the newer college taking power then you are cause I don't want to take more for what we know that already yeah that already depends on how you look at it if you look at the band sorry the power consumed per bandwidth yeah that is going down but you're packing more and more terabit into the same volume so it is going to draw more power yeah yeah yeah so that's reason so so so those are the bus bars which deliver power into the into the cards and those are copper bars which come which are actually turn into the power power module switcher on the bottom of the chassis like these are the power modules used on the system actually if you look at it it's actually very compact model yeah it's a kilowatt this one there's one thing which you were dumb see which is different actually I wish we could power it up and show that you is the logo this say most of this lights up yeah and that looks really cool so I also heard that the low I kiss you the low I didn't know the logo like that but I also heard you can like make it flash or something here so the person knows was like okay those are the beacons and the chassis beacon is this so when so it is something which can be provisioned by the administrator of the system yeah and it will light blue and a person if is I mean so a person who is coming to maintain or do replace a component in the system it just need to watch out for that and and you could basically or in the case wherein you don't need to do anything you can just press this button and so each of the cards have their own vegan so if you want to just target supervisor so the supervisor this beacon is right there it's all so you can see one aspect which is also driven by a painful and I hear it all I can based there no text that's any of that that's a good point there's no way [Laughter] is like what does it look like it looks like a prompt yeah so that's the console okay leave it's nice very nice yeah and s this one stands for status so if you've got two supervisors and you need and someone used to gonna pull out like the top one or one and he's not sure you can make that one flash exactly so he gets the right one so II to provide that has its own Blue Beacon which you can turn on yeah I imagine you guys have gotten a ton of calls saying can you please fix this for us because we got people pulling out stuff and it's going down so can you talk about like capacity because I think that's like how many 20 how many 10 gig could you like so if you look at the line card which you have the 48 port SFP line card yeah which is right here and 24-port qsf be so so if you populate the whole chassis with this line card the it's of peel and curl fix 48 times 4 so that it will be 192 physical ports on the on the chassis yeah and if it is the case of P line card so you would get 96 ports of cassabi so if you if you put a hundred gig in here just so everyone's aware if you put a hundred gig in at the moment yes and the support gets disabled that gets disabled yes but that could still change the change on a future person supervisor but but if you convert 20 is a 25 gig in here that you can put in oh it's a lot 10 gig what are they whatever speed yeah so on the QP line card the kiss of peace natively for 40 gig 100 Inc and beyond but you can convert accuse of reporting to a SF report using an adapter it's called a QC adapter which when you plug it in it becomes the SSP board so when you have the connector you can support one gig by Claude meanness one gig SFP you can support 10 cake by in a tiny case of B and if and 25-year it can be supported by using a breakout cable so you plug in a module which is called sa SP breakout we can break it out into four SFP and those of piece can be ten gig or 25k so it's four because it's a hundred divided by reason why it is for is because the elliptical side it actually supports for physical interfaces okay and that's the reason why you can break like yourself into fall and if you look at the name it's called quad and required stands for for interfaces behind it so it's the four SS Pedialyte some other cool things which I want to show us yes please so you see you notice that like can we put this on the back yeah when I put this supervisor on for you notice that I put this hard which is empty if this is the configuration that you are using it with countenance supervisor and this blank we have to enforce it because if you don't have this card and you leave them that Addison stop open to not avoid that you need to have this and this blank card will be enforced and we use sensor on the chassis you see that yeah yeah um that's actually a hall sensor based solid if extensors which we actually build into the fan clay so if I pull on to find click and show that you so this will be used by the system software to ensure that a card blank is always present on a slot which is on top of the card it's a basically if you if you don't have that in the session of power up or if your warning yeah it gives you one and this is the Hall effect sensor factory so this is actually right behind those those thing already contacts and when you inject a cardan that will trigger a signal digital supervisor software in this demand you like it off is completely empty or not do you like SN if he truck if you cannot go back or something yeah yeah each yeah that's the ball of that and then probably this is the right time to show them basic oh yes you a DBA sake which is used on the supervisor it's actually a large device it same 55 millimeter square device you can see how many balls to dance so this is 2876 balls I just here to say how many 2876 2876 807 okay that's an example Chris are there any other like switches that have like more line cards or that's like in this series but currently this is that only black font science and it's a six lattes how to feed off the product is it's a 9606 and the R stands for redundancy which six launched to slot for the supervisors and four for the line cuts and then I saw this RFID oh so all the card all the individual elements of the system have auto fire built in so the are finally for the chassis is located on the top of the chassis like where it's modified II the factory has star Phi de right here and each of the cars including the supervisor line card they have the RFID right here inside is ejector why do we care we wonder what is it so merely for inventory management without really having to be physically go and scan a barcode so can you wave like so like yeah so the I think the leaders I it's a it's a handle instrument you don't you can be like a - it's like an rfid reader yeah you can be easily five feet away from that and you can just walk by you might have a rightful of these equipment and just walk by the old days of going to write down many what you go and you don't need to go on to go and like if you can this one yes trouble somebody you don't miss it yeah that's awesome do you have your house back back to certainly appreciate it yes so the noise Ludlow not nice is luckier and that's one critical thing to pass on names acoustics so yeah so so we measure it and compare so yeah I don't want to talk the numbers the official answer is it's definitely acquired missus definitely quite okay which is that's good that's awesome I mean so if you compare I mean if you look at the capacity and then for that capacity harmony of the 6500 see what I needed and take that sum total and compare with this yeah certainly much much better yeah and I just coming back to the price I mean we don't know values but I mean again so one of the cool things about this switch is you've got a centralized architecture that's going so all the traffic from lying quite alike sorry from even port to port we go by the hook but it's not going to slow down because it's a line rate yes it's one one of the other advantages I've heard is that this device runs the same operating system as other switches in the same line that's going and it's a single executable back to the lot so correct yeah that's really cool so operating is easy yeah if you want to increase the capacity of this switch you upgrade the supervisor you don't have to like every line code that's good as a practical example I'm just want to summarize as a practical example today you put a hundred gig in here this caught this port is not available but later on when you upgrade that supervisor then you'll be able to get 100 hundred combo that's good yeah yeah that's brilliant yeah in the line cards I mean like there there are most like dummies now like they're really simple all the brains and the browner and the supervisors now that's good idea yes making a lot easier I want to say thank you very much yeah this man is brilliant thanks so much for spending some time with us and showing us the switchin thanks for all your hard work designing this or being involved in the design and the and the building of it I really want to say thanks brilliant all right guys well that was it Rajesh do thank you so much for finding us I mean the catalyst 9 Ches his killer is it's the first new edition since what 20 years since its inception so that's correct and it and I'm getting a signal it is sexy that's the main point the biggest feature anyways thanks guys that's about it and we'll catch you guys next time all the best
