New Cisco Nexus 400G Switches-Models

Cisco launched new 400G Ethernet switches.
The new 400G Ethernet switches fall into two camps, two boxes in the Nexus 9000 family aimed at large-enterprise network customers and two in the 3400-S class targeted at high-bandwidth hyperscale users.
These switches pave the way for Terabit Ethernet switching to become a mainstream technology, wrote Thomas Scheiberote, Cisco vice president of product management, Data Center Networking.
Cisco says 400G will let webscale customers, data-center and 5G-mobile operators create more powerful networks more cost-effectively while offering customers with four times the bandwidth and scale of current networks.
The bandwidth and scale needed for 400G is evident, because:
  • There will be 20 billion to 30 billion online IoT devices in the world through this decade.
  • Users will own more than 25 million 5G-capable devices by 2021 and more than 80 percent of all IP traffic will be bandwidth-hungry, latency-sensitive video content.
  • By 2021 hyperscale data centers will grow from 338 in number at the end of 2016 to 628, representing 53 percent of all installed data-center servers by 2021.
Enterprise users may be most interested in the two new Nexus 9300GX boxes, which Cisco says expand its overarching Application Centric Infrastructure (ACI) and its intent-based networking data-center designs, which in real time can identify and react to changing network conditions. 
ACI brings with it support for Cisco products such as the Tetration Analytics platform, which collects all manner of telemetry information from Cisco and non-Cisco devices on the network. The system then uses machine learning and behavior analysis to provide network administrators a greater understanding and control of their data-center resources.

Machine-to-Machine (M2M)

Machine-to-Machine (M2M) is a technology that aggregates the intercommunications between machines without human intervention.

This technology is already used in a wide range of devices such as vending machines, surveillance systems and sensor-equipped measuring instruments; and its adoption is expected to continue at an accelerated pace. The most important elements for network devices offering the M2M technology are compactness, mobility and durability.

In the case of vending machines, for example, the network device needs to be compact to allow installation inside the machines. Mobility is also important as it is cheaper to use the mobile 4G network than installing a wired broadband line for each vending machine. Depending on the installation location, the network device must also have the durability to withstand the high temperatures in summer.

Cisco 819H/G/HG has been developed to address these issues. Both models feature a palm-sized compact chassis and are compatible with 4G LTE 2.0 wireless LAN. Furthermore, Cisco 819H/HG can operate in temperatures between -23 and +60 deg C and in up to 95% humidity and have superior vibration and impact resistance to withstand industrial use. A wide variety of mounting options are supported including DIN rail, floor and wall mounting.

Use Cases: Cisco’s 25G/100G Technology–Enabling Architectural Transformation

Upgrading the network from 10G to 25G is a straightforward migration option. Hence Cisco offers a gradual migration path with the support of dual-rate optics, where the same 25G optics can operate at both 10G and 25G speeds. With this approach, distribution layer devices can be upgraded to 25G while the access layer still operates at 10G, and the access layer switches can be upgraded over a period of time.

Use case 1: Speed transition with similar cable distances
As access bandwidth increases, campus backbones are transitioning from 10G and 40G speeds to 25G and 100G speeds, and customers are demanding newer optics to support a cabling distance similar to that of existing optics. Cisco’s innovative SFP-10/25G-CSR-S modules support traditional link lengths of up to 300 or 400 m over OM3/OM4 (depending on the fiber quality), now at 25G speeds (Figure 5).
Figure5. Speed transition with similar cable distances

Use case2: Speed migration with dual-rate optics
25G switches and optics provide 2.5 times more bandwidth and are not significantly more expensive than 10G Ethernet solutions. Cisco’s 25G portfolio provides full backward compatibility with 10G with dual-rate optics. These optics will automatically negotiate with the far-end device to the highest speed supported. For example, if the far-end device is capable only of 10 Gbps, the two devices would settle at 10 Gbps speed, meaning that you don’t need to upgrade your infrastructure to 25G right away. Instead you can upgrade the network as part of regular refresh cycles and still have it ready for 25G capabilities (Figure 6).
Figure6. Speed migration with dual-rate optics

Use case3: Speed transition with similar oversubscription ratios
Oversubscription in enterprise campus networks isn’t new. For a long time, the rule of thumb for oversubscription was about 20:1 for access ports and 4:1 for distribution to core. However, these numbers do not really hold up in modern network design. Hence, to retain the recommended oversubscription ratio there is a need to upgrade the uplinks (switch to switch). As natural successors to 10G and 40G technologies, 25G and 100G will help retain the same oversubscription ratios (Figure7).
Figure7. Speed transition with similar oversubscription ratio

Use case4: Access speed transition to 5G
The next generation of Wi-Fi is driving the need for higher speeds, including 2.5G, 5GBASE-T, and 10GBASE-T, in the campus. Most larger enterprise campus networks implement multitier architecture, and these are generally oversubscribed. Network expansions at access or edge have always demanded refreshing the campus core switching capacity. IT needs to reevaluate two major bottleneck points in campus networks, those being the distribution layer that aggregates 10G physical connections and the core switching capacity to maintain 4:1 oversubscription ratios. While mitigating campus core scale and performance challenges and protecting oversubscription ratios, the Cisco Catalyst 9500 Series Switches allow easy and seamless upgrade from existing 10G- or 40G-based infrastructure to 40G- or 100G-based infrastructure (Figure 8).
Figure8. Access speed transition to 5G

Use case5: Load sharing vs. higher speeds
Speed upgrades have outpaced the refresh cycles for cabling, and until now there were two options: (1) rip and replace your existing cabling to support higher speeds, or (2) add additional links to satisfy bandwidth requirements. Neither of these options is ideal. There are significant cost implications, and adding additional uplinks compounds the challenges of achieving effective load sharing that depends on the hashing technologies supported by switches. Moving to faster Ethernet technologies can overcome those concerns as well as add more bandwidth.
Figure9. Load sharing vs. higher speed topologies

Help Wireless Customers Select the Right Cisco Wireless Solutions

Today we believe that every company relies on wireless technology to operate its business. So to meet customers’ diverse needs, particularly for small and medium-sized businesses, Cisco can provide a broad portfolio of wireless solutions.

How to help wireless customers select the right wireless solutions? In the following part there are three approaches for a range of customers.

Three Approaches for a Range of Customers
It is easier when you offer appliance-free, appliance-based, and cloud-based solutions.

On Premises and Appliance-Free

With these solutions, the access points handle the wireless management. So no additional hardware is necessary. They are easy to use, affordable, and work well in environments with up to 25 access points.

Off Premise and Cloud Based

These Cisco® Meraki® cloud-managed solutions are ideal for deployments with access points in multiple remote locations. They are highly scalable, are license based, and require little or no IT staff on site.

On Premises and Appliance-Based

When a company needs 25 to 250 access points in one location, these are the solutions to sell. Network administrators manage the numerous access points with a centralized, wireless LAN controller.

Three Common Network Models
Most customers have small wireless networks, distributed branch locations, or large campuses.
Small Business Local Networks
These customers generally have one location with 25 access points or fewer. They need wireless solutions that are easy to install, easier to manage, and completely reliable. And they want competitive features and performance for an affordable price.
Branch Office Networks
This category of customers requires 25 or more access points in distributed locations. They want wireless solutions that can be licensed, secured, and managed by remote staff, and that will scale up or down quickly to meet changing demand.
Central Campus Networks
This enterprise customer group uses up to 250 access points in a centralized complex. They need broader services, premium performance, bulletproof security, greater network traffic visibility, and simple, centralized control of the many access points.
