Software based network environments
We have recently seen new demands on network environments in companies and research institutions. The entire company structure including production depends on a smooth network operation. The number of network experts in the market is manageable, and we see a trend for the networks to be managed by a small infrastructure team that simultaneously manages storage, servers, virtualization, containers, and applications. If necessary, the network should be able to scale delivery times quickly and independently of manufacturer.
The above graph of a Layer 3 network shows a setup that allows you to scale to 1536 ports at 50Gbps by just adding another leaf switch. With a blocking factor of 1:3. For a Non Blocking Fabric 6 spine switches are needed in this case. Leaf switches with 25Gbe ports require only 3 spine switches for non-blocking.
The example of the successful network startup par excellence. In simple terms, Cumulus is a network operating system based on Debian Linux. However, it is much more than that. It is a network solution trusted by the largest companies in the world. It can be operated on switch hardware from many manufacturers (DELL, HPE, Lenovo, Mellanox, Edgecore and many more). It is based on standards, all developments are included in the Linux kernel. It's easy to manage and automate using the same tools as your servers. It is perfectly optimized for a scalable Layer 3 environment and offers a large and robust feature set.More about Cumulus Linux
Mellanox may not yet be familiar to anyone in the Ethernet environment, but it should (not even after the $ 6.9 billion acquisition by NVIDIA). Mellanox is one of the few manufacturers to produce its own Switch ASIC (CPU), which not only provides one of the best latency and throughput rates (400Gbit / s linerate) on the market. They offer features such as native VXLAN and EVPN support as well as the Precision Time Protocol (PTP). In addition to the switches, Mellanox also manufactures its own 10, 25, 50, 100, 200Gbit Ethernet network cards. The Mellanox RDMA (Remote Direct Memory Access) support is probably indispensable in any major IT solutions (Microsoft HyperV and Storage Space Direct, VMware vSphere and many more). The Mellanox switches come standard with the Onyx operating system, but can also be used with Cumulus, Sonic and many other network operating systems. Cumulus and Mellanox are particularly well matched.
