Spanning Across the Data Center or Breakouts Within the Rack Short Reach (SR) multi-mode optics are the lowest priced optical interconnects available today that use optical connectors to separate the transceiver from the optical fibers. Although both support 100m reach, AOCs are much less expensive that SR optics but the former functions as a complete […]
This blog is Part 2 in a 3-part series on Mellanox’s high-speed interconnect products. My first blog covered Direct Attach Copper (DAC) cables which are the least expensive way to create a high-speed 25G/50G/100Gb/s interconnect, but have a maximum reach of about 3-5 meters. Active Optical Cables (AOCs) pick it up from there and can reach up to 100-200 meters and are the least expensive, optical links available. Widely used in HPCs and more recently became popular in hyperscale. enterprise and storage systems.
Part 1: The DDoS Threat and Changing Landscape of Protection Distributed Denial of Service (DDoS) attacks have been around for quite a while and their profile was raised again last month when Dyn Inc., one of the largest DNS provider sites, was hit with a very large scale (tens of millions of zombie agents) attack […]
Part I of Three Part Blog Series on Cables & Transceivers CAT-5e cabling and 1GBASE-T have dominated the data center interconnect scene for 15 plus years. However, the transition to 10G Ethernet proved to be a significant hindrance in both power consumption and cost. That’s when Direct Attach Copper (DAC) cabling, aka Twinax, snuck in […]
You want your cloud network to be software-defined, but without compromising performance or efficiency. How about 25G, 50G or 100Gbps speed without glitches? How about earth-shattering DPDK or virtualized network function (VNF) performance? How about unleashing your NVMe SSD speed potentials with software defined storage? The hyperscale giants are doing all of this and more […]
