Alcatel-Lucent provides the OmniSwitch family of switches, providing data center switching, Ethernet & LAN switches, support for IoT and edge solutions, SDN, ruggedization and industrial-grade solutions, and WebSmart switches.
Our data management depends on the networking infrastructure and this product has provided all tools that are required. Our IT operations have been stable due to reliable security and networking services enhanced by this product. It easily identifies critical missions that may affect our operations and notify the service team for immediate action. My marketing department has discovered the most effective marketing channels that can attract more customers through a reliable internet connection.
Cisco Nexus Series Switches is well suited, for any spine and leaf architecture has it could be done through ACI, EVPN, or use as L2 only it could be used in different environments and thanks to these high scalability it could be evolve easily. Some advanced solutions like AI or centralized management, are less easy to integrate and need other solutions to interact and also not always planned since the installation.
Maintenance, upgrades, and software certification can be performed without service interruptions because of the modular nature of NX-OS and features such as In-Service Software Upgrade (ISSU) and the capability for processes to restart dynamically
FabricPath:
Enables each device to build an overall view of the topology; this is similar to other link state routing protocols. Each device in the FabricPath topology is identified by a switch-id. The Layer 2 forwarding tables are built based on reachability to each switch-id, not by the MAC address. Eliminates spanning-tree to maximize network bandwidth and flexibility in topological configurations, as well as simplify operational support and configuration. This enables a tremendous amount of flexibility on the topology because you can now build FabricPath topologies for Layer 2-based networks the same as for Layer 3-based networks
Overlay Transport Virtualization (OTV): Enables the Layer 2 extension between distributed data centers over any transport Layer 3 network
Implementing jumbo frames on interfaces of its fabric extender series (N2k, etc.) by editing the network QoS does not have to be a global configuration that would affect all its interfaces. It can be improved to become just an interface configuration.
Licensing on the NXOS is a bit complicated and expensive. I understand that the Nexus is made for core data center switching but it does not have to break the bank.
OTV technology is for Nexus only. Based on the advantage of the technology, it should be made vendor-neutral to accommodate other vendor devices.
Because its the best tech out there and all our engineers are very used to working on Cisco switches. It is great for troubleshooting issues on L2 and L3. It provides bandwidth and throughput like no other switch out there. We are a ACI shop so the Nexus blends nicely with that
The platform has a good performance. The major issue is all the bugs you can discover across the operations, and it can be a big challenge depending on the number of Cisco Nexus Series Switches you have deployed. In our case, we own more than 200 Cisco Nexus Series Switches 9k, and we face an upgrade process, it could be a long time project to grant a new software deployment in all our switches platform.
These switches are very fast. They've been designed to work within the data center. We connect them to Cisco UCS-B Mini servers with the storage being directly attached. They are able to handle the data traffic pretty easily. We can also move servers pretty fast from data center to data center without overloading them. This has allowed our company to stay running during any kind of conditional outage. We have come to really rely on them for business continuity.
Overall, Cisco has great products and I believe that they believe in the philosophy of a great customer experience. Although there have been a few technical support issues that caused a lot of company anxiety, in most cases, Cisco has gone above and beyond in making a valiant effort to help the customer solve any issues.
Most problems that face our company has been solved by an effective performance of this product. The operation and continuity of our business programs are boosted by great network connections. Alcatel company has been helpful in providing training and development guidelines where possible. The system performance has built a powerful operation base that can identify and provide solutions to business challenges. The digital working base for all our plans has been implemented.
The Cisco 9000 stacks up quite well against the Cisco Catalyst 3850 switches. The additional features available in the Nexus 9000, such as VPN, FCoE, 40 gigabits, give us the ability to support the future needs of the company in our data center. The Nexus 9000 allowed us to condense our core and aggregation environment that comprised of 2 Catalyst 6504 and 2 Catalyst 6509 to a port of Nexus 9000. Although the Catalyst 3850 would be sufficient to handle routing, those features in the Nexus 9000 made it the clear choice for us.
The Nexus 3000 series switches are data center switches, so I would say they have similar security ability to other switches in this segment. I don't have a lot of experience doing more than basic ACL security on switches, but I know these can be integrated into other security solutions like Cisco ISE and 802.1x authentication. It could also be integrated into an ACI solution to add micro segmentation, which would bring in other security functions.
