06 NEWS IN BRIEF Networks Europe helps you to understand the art of the possible as the news desk highlights some of the stories currently catching their attention. Power distribution in confined spaces Manufacturers are moving away from stand-alone power distribution enclosures for individual control units. Instead, they are looking to create an overarching system within a single enclosure, serving multiple controllers – each one assigned to a specific machine. The new Rittal RiLine Compact, designed for control units that require a maximum current of 125 A, addresses this need. Despite its size, the busbar system distributes power effectively and reliably, in compliance with all applicable standards. RiLine Compact comprises a board with busbars entirely enclosed in covers that safeguard against unintentional contact. A connection can be easily established anywhere along the length of a busbar via a series of access apertures (called the pitch pattern) in the board. Switchgear and control units can be simply “plugged in” using a variety of adaptors. In addition, an adapter for connection to round conductors is available, as well as a variety of functional modules for motor and power control. One of RiLine Compact’s primary strengths is that it can be rapidly configured, assembled and installed. n 28-AWG Data Centre Cabling announced Panduit EMEA has announced its 28-AWG cabling system offering up to 50% space saving and reduced costs over 24-AWG cabling systems. New developments in cabling technology and the need for increased efficiency within data centres have provided the impetus for introducing 28-AWG copper cable in these installations. 28-AWG cabling offers significantly smaller diameter wire than the ubiquitous 24- AWG copper conductors generally used in network cabinet and rack installations, and maintains data integrity. Dependent on the cable type, Panduit 28-AWG cable offers between 48% and 41% reduction in size. For example, a Category 6 cord with 28-AWG wires is 0.15 inches (3.8mm) in OD, which is 41 percent the size of the typical 24-AWG Category 6 cord. Category 5e and Category 6A patch cords have similar size savings. The requirement to provide increased IT capabilities in the same or smaller spaces has led to over-crowded cable runs and racks within many data centres. This leads to congested cable pathways, insufficient space for new equipment and the challenge of patching bulk when using high-density patch panels. Standards committees have started discussing the addition of 28 AWG cabling to the standards. Today, Panduit 28-AWG cabling meets all performance standards, but does not meet the 22-26 AWG size requirement. n Cavium QLogic accelerates NVMe over fabrics adoption Cavium’s family of QLogic Gen 6 Fibre Channel and FastLinQ Ethernet adapters will support NVMe over Fabrics (NVMe-oF) technology, enabling the scale out of flash storage platforms. NVMe-oF defines an efficient mechanism to utilise NVMe devices in large-scale storage deployments and provides investment protection by leveraging the latest innovations and advances in low latency SSD flash to be realised over proven Fibre Channel and Ethernet RDMA fabrics. NVMe over Fabrics enables NVMe storage devices to be shared, pooled and managed more effectively across a fabric. With support for 32GFC and 100Gbps Ethernet, the 2690 Enhanced Gen 5 and 2700 Series Gen 6 Fibre Channel, and FastLinQ 45000 series Ethernet adapters, provide streamlined access to low latency NVMe SSDs enabling scale out architectures, simplifying design, reducing overhead and improving performance. Cavium has commenced an early access program for NVMe over Fibre Channel (FC-NVMe) and NVMe over Universal RDMA (NVMe-oF) for select partners, with plans to expand the program in Q2’17. n www.networkseuropemagazine.com
