The Power over Ethernet Revolution rolls on

By on • ( Leave a comment )

2019 is big year for Power over Ethernet (PoE). This system for delivering power and data over twisted pair cabling is getting a big boost from the late 2018 release of the IEEE 802.3bt standard, defining PoE over four pairs instead of two. This change means PoE will be able to support more devices that require higher power. For this reason — along with the rise of the Internet of Things — more than 700 million PoE-enabled Ethernet switch ports and 280 million PoE devices are expected to ship in the next five years, according to market research firm Dell’Oro.

RoCE or iWARP for Low Latency?

Enterprise customers will soon require the low latency networking that RDMA offers so that they can address a variety of different applications, such as Oracle and SAP, and also implement software-defined storage using Windows Storage Spaces Direct (S2D) or VMware vSAN. There are three protocols that can be used in RDMA deployment: RDMA over InfiniBand, RDMA over Converged Ethernet (RoCE), and RDMA over iWARP. Given that there are several possible routes to go down, how do you ensure you pick the right protocol for your specific tasks?

The New York City subway system is the United States’ largest transportation network, operating 24 hours a day, 365 days a year. But just a few years ago, more than 5.5 million riders who rely upon the subway system every day, had no access to cellular and Wi-Fi connectivity while traveling underground. A high-speed communications and IP infrastructure was needed to not only keep riders connected but also to support public safety and emerging smart city technologies.

RF Code’s new White Paper, Standing at the Edge? Look Before You Leap,” defines the edge – what it is, where it is, and its benefits, and reveals the obstacles and hazards IT professionals need to address to ensure their edge deployments deliver the rewards their businesses demand. The paper explores critical information for those developing an edge data center deployment strategy. According to Gartner, within the next four years 75% of data generated by enterprises will be processed at the edge (up from just 10% today).

Smart cities bring together infrastructure and technology to improve the quality of life of citizens and enhance their interactions with the urban environment. But how can data from areas such as public transport, air quality meters and energy production be integrated and effectively used? By rendering more technology capable of communicating across platforms, IoT generates more data that can help improve various aspects of daily life. Cities can identify both opportunities and challenges in real-time, reducing costs by pinpointing issues prior to their emergence and allocating resources more accurately to maximize impact.

Tips to Identify Copper Clad Aluminium (CCA) Cables

If it sounds too good to be true, it might be. Don’t get too excited if you find Category 6 cable available online for practically half what you’ve been paying for that brand name. Even if it claims TIA-568-C compliance, includes the UL listing mark and even has a ETL verification legend printed right on the cable, make sure that cable isn’t made with copper clad aluminum (CCA). Cables made with CCA conductors are simply not worth the risk, even at the lower price. Not only are they non-standards compliant, but they often do not have a valid UL safety listing per the National Electric Not Worth the Savings or the RiskCode (NEC)..
