Training FastTrack. "Networking basics." "Equipment for data centers." Eddie Martin. December, 2012

About a year ago, I noticed an interesting and fascinating series of lectures by Eddie Martin, which is incredibly intelligible, thanks to his history and examples from real life, as well as his tremendous experience in teaching, allows him to gain an understanding of quite complex technologies.
Training FastTrack. "Networking basics." "Equipment for data centers." Eddie Martin. December, 2012  
We continue the cycle of 27 articles on the basis of his lectures:
01/02: "Understanding the OSI model" Part 1 / Part 2
03: "Understanding the Cisco Architecture"
04/05: "Basics of commutation or switches" Part 1 / Part 2
06: "Cisco Swichs"
07: "The scope of network switches, the value of Cisco switches"
08/09: "Basics of wireless LAN" Part 1 / Part 2
10: «Products in the sphere of wireless local area networks»
11: "The Value of Cisco Wireless LANs"
12: "Basics of Routing"
13: "The structure of routers, routing platforms from Cisco"
14: "The Value of Cisco Routers"
15/16: "The basis of data centers" Part 1 / Part 2
17: "Equipment for data centers"
And here's the seventeenth of them.
the Cisco Nexus 7000 architecture is discussed here .
The 10-slot chassis has a slightly different form factor - here the factory modules (Fabric Module) are pulled back.
The chassis, designed to accommodate 18 modules, is designated Nexus 7018. It has the same functionality, but large dimensions. These are the largest switches of this series. The difference between them can be clearly seen in the pictures and here .
But if you do not need such a large chassis, then it's better to look at the Nexus 5000 series. They also got the Nexus OS. In the chassis 502? you can put various expansion modules depending on what you want to do. We have three modifications of the modules for ? 6 and 8 ports with a capacity of 10 gigabit. Can be used, both traditional fiber, and Ethernet. This chassis can serve as a supervisor for the 2200 series switches.
Factory extensions. There are several factory expanders. This is what the FEX 2248 TP switch module looks like. It has ??? Gbps Ethernet Uplink ports and 48 ports for gigabit connections and provides data transfer rates of 40 gigabits per second in each direction, that is, only 80 gigabit.
If you need a 10-gigabit factory extender, then you should take the model FEX 2232PP and there will be 32 ten-gigabit ports.
Again, you can have several similar expanders that will be controlled by the 5000 series chassis.
The Nexus 1010V looks like a plastic box, because it's software for virtualization, not hardware. This is the virtual supervisor module.
It works as a 4-port switch, which you put inside your virtual server, and as a result you get up to 128 virtual ports-interfaces. All this can be used for security purposes and for many more things that we do to you in data centers. We discussed this issue in detail in previous lectures.
Now I will show you what the chassis of the 5108 looks like, which is installed on top of the Nexus 6200 chassis. This is the chassis for hosting the UCSB 200 blade servers. The "B" letter means "blade". The double after shows the number of sockets, in this case 2. The digits after it show the model, 00 - the base model, 20 or 30 have more RAM and storage space. Here the picture shows VIC network cards, virtualized NIC cards. So, how many sockets are in the UCSB 400 model? 4 sockets, in each 8 cores. This way you can get up to 32 cores and 48 DIMMs. This is a B-series, a series of blade servers.
Now let's look at the servers designed for rack mounting - C-series. Model UCS C460M1 is a stand-alone server with four sockets. Under its cover, you can place up to 4 eight-core Intel Xeon 7500 processors.
I'll show you a sample of the memory expansion technology on the example of the USC C250 series module, in which our ASICs are installed to expand the memory capacity. They have 2 times more memory than traditional modules for 2 sockets - 384 GB vs. 198 GB. Modules with less memory are cheaper.
Consider the USC 2208 XP Fabric Extender network module. Their function is Fabric Interconnect. Each consists of 8 ports of 10 gigabit. For each 6200 chassis you can install up to 2 expanders and get a throughput of 160 gigabits per second.
We have already spoken with you about VBlock previously . Chassis VBlock are similar to the system blocks of personal computers. This is a virtual data center, a solution for creating a large virtual architecture in which you can host blade servers, switches, storage, etc., that is, virtually the entire line of modern physical Cisco devices.
You can place in this chassis exactly the equipment that is required for your data warehouse. This is a ready-made solution for the construction of full-featured data centers.
