RoCE: RDMA over Converged Ethernet for High-Efficiency Network Performance

In the era of data, the requirements for a faster, more efficient, and scalable network has never been reduced. Since the traditional TCP/IP Ethernet connections are CPU intensitive and require extra processing and copying of the data, they can’t meet the current network needs any more. In that context, the RDMA over Converged Ethernet (RoCE) arrives. Background Knowledge: What Is RDMA? RDMA (remote direct memory access) is a technology that enables direct memory access from the memory of on...

Understanding PoE Standards and PoE Wattage

PoE (Power over Ethernet) technology allows PSE (Power Sourcing Equipment, such as a PoE switch) to use Ethernet cables to deliver both power and data simultaneously to PD (Powered Device, like IP cameras and VoIP phones), which can simplify cabling installation and save cost. Different PoE standards like IEEE802.3af, 802.3at and 802.3bt are released by IEEE (Institute of Electrical and Electronic Engineers) to regulate the amount of power delivered to those PDs. Then how much do you know about ...

How to Configure MLAG on FS N-Series Switch With Cumulus Linux?

Data center and cloud computing networks require both the highest level of network bandwidth and reliability. MLAG (Multi-Chassis Link Aggregation) makes it possible by taking the benefits of link aggregation, and spreading them across a pair of data center switches to deliver system level redundancy as well as network-level resiliency. It significantly improves network efficiency and simplifies system management, which can be used at various places in the network to eliminate bottlenecks and pr...
