Cisco Nexus Series Switches

If you need a switch that simply works and is available 365/7/24, then this is certainly one that should be at the top of your list. In all the years we've been running these Cisco Nexus 9500 Series Switches, the only time we restart them is when we are doing software upgrades. They are rock solid.

Cisco Nexus 9000 Series Switches are very well suited for a DC environment.

I have been using Cisco Nexus Series Switches for a long time and found them more appropriate compared with others, but maybe some other vendors have different switches to offer. I haven't tried them so can't say whether Cisco is missing any options or tools.

Cisco Nexus is almost the best for the data center. The virtualization ability (Virtual Device Context) of a Cisco Nexus to compress the need for multiple hardware in the data center is top-notch. Cisco Nexus also integrates well with DevOp automation tools due to its flexible API. Hence, the experience you get with network automation and programmability on the NXOS is huge. Configuration of Cisco Nexus is pretty easy. Cisco has great documentation to enable anyone to configure a Cisco Nexus switch. The only less appropriate scenario I see in terms of configuration is that I have to do VPC to a switch then connect a server to the non-VPC switch. It would be interesting to set up VPC between Nexus and a Host server, thereby eliminating the switch in between.

Data center keys are designed especially designed to support very high traffic in an effective way. We also want to assess the SDN function to make sure that the company is useful. WARNING: The same key does not provide a complete SDN experience. The application environment and the entire infrastructure must be designed. It is strongly suggested that you can avoid being used for normal positions that are not very specific to load very high networks to load very specific requirements. There are many families and other brands and is suitable for their services in a simple conversation. The key support series considers the Cisco Nexus 9000 training team and the architecture of the same catalyst.

The Cisco Nexus 9000 is well suited as the core switch router in data centers. We use them as our main routers using both EIGRP and BGP. We make use of the increased thru-put it's capable of with 10GB ethernet ports and the 40 gigabits interconnect between them. It's not well suited for non-data center locations. The features of the Nexus 9000 are wasted if not utilized in a data center environment.

We had Catalyst 6500s in our core setup in HA (high availability). It was a collapsed Core/Distribution. We upgraded to the Nexus line of switches when we moved our Data Center. We went with a 3 tiered approach and moved the distribution (Nexus 9300s) to a cable distribution point in each building. This saved us a ton of money on fiber cabling. We choose the Nexus 9500s for our Core and Nexus 9300s for our Server Farm.

It is the leader in data center switches and I can say that managing the required traffic throughput is essential for any large enterprise. In addition, Cisco support is industry-leading, always very useful with hardware or software issues, and well worth the extra cost.

If you want to have worthwhile switches and positive traffic handling results, you should consider purchasing Cisco Nexus 9000 series switches as they will reduce downtime, have better network fluidity, and better scalable results. The implementation takes longer than expected, but the technical support and user community add to the benefits and help a lot.

Cisco offers a competitive data center offering with the Nexus 9Ks, whether in traditional NXOS mode or in managed-fabric ACI mode. As long as Cisco retains standard (fixed/perpetual) licensing and doesn't force users into costly subscription licensing the Nexus 9000s will remain our go-to for our data center switching needs.

the connection is ok and we have used it for years without [many] issues. it is suitable for our data center and we use it to connect our servers to set up a private cloud

The support was prompt and we did not encounter much issues with them

It did not give much problems since go-live and our engineers only need to do routine maintenance and patches

Datacenter caliber switches are very specifically designed to support VERY high loads of traffic in an effective way. Also, it would be nice to evaluate its SDN (ACI) capabilities to see if it's worth it to leverage in the company. Warning: the switch itself won't give a FULL SDN experience. The entire application and Infrastructure environment needs to be architected for this. I would strongly suggest avoiding using them for regular site branches unless there are very specific requirements with very high network loads (>100 Gbps). There are plenty of other families and brands that are better suited to serve them at a much lower cost and with easier interaction. Consider training the team in charge of supporting Cisco Nexus 9000 Series Switches as commands and architecture are not the same as Catalyst.

Cisco has a strong user community and customer focus. There are multiple features like performance REST API are included in these switches. Scale availability is another feather for Cisco Nexus 900 Series Switches.

These are data center level (enterprise-level) devices and should be treated as such. While this also means a higher cost, it also means a higher level of service and quality. These would be the switch of choice for establishing core LAN networks in a data center environment. I would not install these at customer sites as the cost would be too high and offer more capabilities than necessary.

It is a leader in data center switches, and I would say it is needed for any large enterprises to handle the traffic throughput that they would need. Also, Cisco support is the best out there and is always very helpful in hardware or software issues and well worth the extra cost.

Cisco Nexus handles high valued traffic, from different database, and ensures there is proper switches which works with several applications. Further, Cisco Nexus uses the Artificial intelligence capacity, that creates a sustainable analytical approach. The cores that Cisco Nexus has for sppedy processing are above 256 GBPS. Finally, Cisco Nexus helps us manage our different data centers, with the right network, for efficient traffic recording.

Cisco Catalyst switch 9300s has been a smooth upgrade/transition from Cisco Catalyst 3750s as it was a simple config transition from 3750s config with a few modifications on the uplink modules config. The Catalyst 9300 has increased our throughput and bandwidth between MDF and Core which was a huge improvement for users and businesses.

For me, the Cisco Nexus 9000 Series Switches adapt to any scenario, such as a large company or a small company. Since modularity allows us to start with something small and increase according to our needs, you can integrate switches from another series such as the 2000, and it's compatible with those of the 9000 series. Therefore, it is recommended for any type of business.

[It's] most suitable in [a] data center environment. You can also use [it] to connect servers to get high availability uplinks. Bundle links (port channels) to get more bandwidth for connected devices. Use different models for 1G, 10G, 40G requirements. Split 40G ports into 10G ports in some cases. You can also use as access layer switches as well as distribution layer switches.

[Cisco] Nexus is very well suited when processing PO's or invoices received from vendors. This can take the form of uploading PDFs or having vendors send them to you directly. It does have an autoscan feature but often times in my experience, getting the documents into the correct format takes longer than the actual processing manually.

Cisco Nexus provides a solution to connect your data center that is very reliable and solid. During our years of use with this equipment we have not had major problems such as service stops or network drops. Before any hardware problems [occured], the support quickly provided us with an RMA for replacement, five stars definitely.

Well-suited for enterprise and datacenter use cases. Spine leaf architecture with Cisco Nexus 9000 leads to high availability and easy scalability. It's compatible with most other vendor equipment as well.

Not suited for core and backbone networks or for small enterprises due to high capital expenditure.

Cisco Nexus switches are designed for data center environments or other environments that require high bandwidth switching. This includes mainly server connections with many virtual machines residing on them, fabric channel of ethernet[,] or something similar. Nexus is not suited for user switches, WAN switches, or other switches that don't need a lot of processing power.

Cisco Nexus switches are best suited for core network, extremely high uptime requirements, unique fibre/copper network cabling configurations, and necessary monitoring. Contrarily, it's best to choose other switches for small branch office networking, simple cabling requirements for low usage and for networks with minimal network mgmt skills in house.

It's well suited for medium and large enterprise scales looking for converged datacenter infrastructure and low latencies.
Cisco Nexus is a very reliable platform and Cisco is the biggest player on the Network market. They also have a great support.
The licensing model is still a little bit confusing for me, and the prices in Brazil are quite expensive. So, these are the cons to consider.
