The NextGen Exponential Switching is here

switch1

Carrier-class switches for converged enterprise branch offices, campuses, and data centers, as well as
for service provider deployments. They address
escalating demands for high availability, unified
communications, mobility, and virtualization within
enterprise networks.

switch2

Switches operate as a single device, reducing operational expense and management complexity.


switch3

High 1GbE, 10GbE, 40GbE, and 100GbE port densities.

switch4

Ensure proper prioritization of voice, video, and multiple levels of data traffic, with room to converge other networks such as building automation and video security systems.


switch5

SWITCH6

High-performance, high-density platforms that satisfy
the needs of today’s most demanding enterprise and
service provider environments. Designed for
top-of-rack, end-of-row, and spine-and-core
aggregation deployments in modern data centers,
QFX Series switches can be deployed as 10GbE,
40GbE or 100GbE access, spine, core or aggregation
devices in Virtual Chassis, Virtual Chassis Fabric,
Multi-Chassis LAG and Junos Fusion architectures.

switch10

With throughput of up to 6 Tbps per slot, QFX Series switches deliver sustained wire-speed switching with low latency and jitter for virtualized data center environments.

switch11

QFX Series switches provide the universal building blocks for multiple data center fabric architectures, including Junos Fusion, QFabric System, Virtual Chassis and Virtual Chassis Fabric.
.

switch12

Standards-based bridging, routing, VMware NSX Layer 2 gateway, and Fibre Channel technology enable interoperability and easy integration.

switch7

The QFabric® System is composed of multiple
components working together as a single switch.
It flattens the network to a single tier to provide
high-performance, any-to-any connectivity and
management simplicity, making it the ideal network
foundation for cloud-ready, virtualized data centers.

 

Scales to 40 Tbps to deliver unprecedented capacity beyond 10GbE at the access layer.

 

Ultra-low Deterministic Latency is ideal for supporting latency-sensitive applications, east-west traffic flows, virtualization, cloud, and other high-performance data center initiatives.

 

Single-Switch Management greatly simplifies data center operations with less complexity and lower power, space, cooling, and operational costs.

 "east-to-west", No "north-to-south" traffic. Everybody is just 1 HOP away.

NextGen Exponential DataCenter for SIMPLE.OPEN.SMART NETWORKING youtube

Enterprises build DataCenters, where they house their Computer and Network infrastructure. Such DataCenters consist normally of a number of racks, which altogether consist a Network Node.

The exchange of information (DATA) between the machines in the enterprise’s DataCenter necessitates the flow of information between computers and servers, which communicate between each other via networking devices, which in today’s DataCenters are layered in 1, 2 or even 3 layers (Access Layer, Aggregation Layer and Core Layer). In some cases where FCoE configurations are used for Storage systems, even a fourth Layer is utilized (normally within the Access Layer). Thus a 3 ½  layer-structure is commonplace in many DataCenters.

In order to deliver the response on a user’s screen of his/her smartphone, laptop or office computer, the information has to travel through very fast telecommunication lines within the DataCenter and if the requested information is seated somewhere else, then computers in two or more Datacenters have to be linked with each other.

The Networking Technologies and the Computational Technologies are in competition.

Computational Technologies, in contrast to the Networking-Technologies, underwent drastic changes in the last years 15-20 years. These changes have resulted in significant changes on the way IT infrastructure is setup and used. It has also influenced drastically the economics of IT deployments.

nextgendatacenter6It is expected that DataCenters will grow further. It is further expected that the pattern of the flow of DATA between the Servers in the DataCenter will change dramatically. North-South traffic will give way to East-West traffic.

This facts makes it necessary to adapt accordingly the DataCenter internal structures soonest possible.

nextgendatacenter5

The traditional data center has become overly complex, costly, and extremely inefficient. Server virtualization is significantly changing the rules of data center design. Network performance requirements such as throughput, low latency, quality of services and availability have become increasingly important in environments where server virtualization is introduced. To meet the growing demands of server virtualization, the data center network should be virtualized as well to bring greater flexibility and added redundancy to the network infrastructure. Without taking steps to support higher virtual machine densities, organizations put their server virtualization initiatives at risk, and this can ultimately impact application availability and the ability to optimize data center hosted application performance.

While the structure of  Applications, Computing and Storage have evolved  and transformed the way they are setup and used, the Networks in the DataCenters still remain unchanged and they continue been built with the legacy structure of the three layers ACCESS – AGGREGATION – CORE.
Given the long distances which the DATA-packets have to cover within the DataCenter, this type of layered network structure cannot deliver any more the necessary performance levels in the new era (See BIG DATA ).
 

nextgendatacenter1

It is urgent to simplify today’s multilayered network structures in the DataCenters.

What is needed is to flatten the paths which the DATA-packets have to travel through, in order to achieve shorter routes between the servers and thus be able to shorten the overall processing time.

It is a mathematically proven fact that the ideal structure of a DataCenter will not contain 3 layers, but just 1. 

 

Here is the proof:
n network nodes can be interconnected between each other with a quantity of routes equal to:  n*(n-1)/2  for n=1,2,...N.
The optimal value of n, yielding the highest speed and lowest complexity is n=1.

This means, the Network must consist of 1 Node !

Herebelow is our 1- or 2-step proposals how to arrive at this optimal result. The transformation of the DataCenter in order to arrive at the 1-Node Network structure can be realized either in two (2) steps utilizing in the first step Virtual Chassis Technology, or in just one (1) step utilizing directly Juniper Networks’ QFABRIC system.

nextgendatacenter2In the DataCenter shown here, the three layers have shrunk to just two by use of Virtual Chassis technology of Juniper Networks. With this all ports of the ACCESS LAYER and the AGGREGATION LAYER are integrated into one Switch with a virtual chassis. Thus, the new structure comprises of just two layers: the CORE LAYER and the "New-ACCESS" LAYER.

This new design is showing the final configuration of the new DataCenter, which now is a 1-Node DataCenter deploying Juniper Networks’ QFABRIC technology, connecting all ports with each other directly with 1 HOP.

In both cases above, the Security Services have been concentrated into integrated Security Appliances, and in this case a redundant configuration using an HA (High Availability is deployed.

 

The benefits provided by the Virtualization and the QFabric are many. Between them:

  • Significant decrease of the number of devices
  • Incomparable ease in managing the devices andf the Network
  • Simple Expandability of the Network by connecting the additional new ports directly with the existing ports (1 HOP)
  • Drastically decreased number of connection cables
  • Significant decrease of switching-time port-to-port by up to 90%: 2-5  sec
  • Uniform Operating System JUNOS in the complete Network
  • Shrinking of the ecological footprint
  • Substantial decrease of covered surface in the DataCenter and corresponding decrease of cooling facilities and expenses
  • Savings in the Cost of Ownership and decrease of the overall maintenance cost
