What do you care most about a data center switch? The number of ports? The switch class? Or the operating system? Here is a comparison of two 48-port 10gbe switches from FS.COM and Cisco. Let’s see what the vendors value for their own devices? FS N5850-48S6Q 48-port 10Gbe Switch Overview FS N5850-48S6Q network switch is initially positioned as the bare metal switch, but you can choose the one pre-installed with Broadcom ICOS or Cumulus Linux. The combination of Cumulus Linux makes the N5850-48S6Q 10gbe switch stand head and shoulders above its counterparts. Here we revolve around the one with Cumulus Linux. FS N5850-48S6Q network switch comes with 48 SFP+ 10Gb ports and 6 QSFP+ 40Gb ports, and each 40Gb port can operate in native 40-Gbps or 4 x 10-Gbps mode. N5850-48S6Q is a top-of-rack (TOR) or leaf 10Gbe switch in a compact 1U form factor, ideally suited for high performance and programmable data center environments. It performs excellent low latency and power efficiency in a

Have you ever wondered that one day you could customize switches like the way you configure your own PC? It is actually happening. As vendors researches and develops switch structures by decoupling software from hardware, bare metal switch come into being. The switching technology can be programmed like Cumulus Linux servers. They may appear in a lot more average enterprises in the next few years with ONIE moving into the spotlight. Clearing the Fog Around Bare Metal Switch Bare metal switch, also known as white-box switch, is solely a switch box with a chip inside it. What makes it differ from original network switch ? Well, common Ethernet switches, also called closed switches, are sold with hardware and software together. That is to say, if you buy a Juniper EX or MX series network switches, you also buy JUNOS; if you buy a Cisco Catalyst network switch, you have to buy Cisco IOS. This is in contrast to bare metal switches which widen the choice available to network buyers. The

As the data center expands, the traditional fiber optic cables can hardly meet the high requirements for networking, as they not only occupy a large room, but also make it more difficult to manage cables. In contrast, MTP cable  and MPO cable provide a multi-fiber connectivity in one connector to support higher bandwidth and higher density applications, thus becoming popular. Generally, MTP/MPO cables are classified into three types: trunk cable, harness cable and conversion cable. See what they are and their applications. Common MTP/MPO Cable Types MTP/MPO Trunk Cable MTP/MPO trunk cable is a cable with two MPO or MTP connectors at both ends, with nothing different from ordinary patch cables seen from outside. However, the truth is that the cable usually accommodates 12, 24, 48 and even 72 fibers, and the ends are terminated with 12-fiber or 24-fiber MTP/MPO connectors according to customer’s choice. FS MTP/MPO trunk cables are designed for high density application which offer

Recently, many people have jumped on the bandwagon to use the 24-port Gigabit managed switch with advanced administrative controls. In particular, 24-port switch with PoE technology provides people with great convenience. However, the more power it sustains, the noisier it is. Have you been hassled by the endless noise or interrupted in your work? It is time to put an end to work frustration with fanless 24-port Gigabit switch. What’s the Magic with Fanless 24-Port Gigabit Switch? A Gigabit Ethernet switch without fan doesn’t mean that it does not have cooling system. Instead, it adopts a passive cooling system which achieves high level of natural convection and heat dissipation by a heat spreader or a heat sink to maximize the radiation and convection heat transfer modes. The passive cooling makes your switch dumb but not numb, as it still works efficiently. In a word, fanless switch is the most suitable in silent and energy-saving environments. Here introduce three distinctive

FTTH, the concept that has been hotly debated by people in recent years, drives the demand for fiber optic cables and its related products. However, fiber optic cable is fragile and hard to splice, which is worthy of consideration before installation. To make good use of fiber optic cable, well-organized fiber optic cable installation is a necessity. Fiber Optic Cable Introduction Fiber optic cable is a technology that uses small threads made of glass or plastic (fibers) to transmit data. However cheap and light it is, the material brings a troubling problem in fiber optic cable installation. It is an assembly similar to an electrical cable while the former one carries light and the latter carries electricity. Normally, fiber optic cable comes in two types, namely, single mode fiber (SMF) and multimode fiber (MMF). Single mode fiber is suitable for long distance data transmission while multimode optical fiber is used in short distance transmission such as computer network linkin

Almost every device connected to the Internet needs an IP address. Previously, the countless IP addresses are assigned manually, which costs a lot of time and energy. As DHCP emerges, IT specialists are not required any longer to spend countless hours providing IPs for every device connected to the network device. But what is DHCP? How does it work and how to configure DHCP for multiple VLANs? What Is DHCP? DHCP – Dynamic Host Configuration Protocol is a network management protocol used on TCP/IP network. There may be at least a DHCP server and many DHCP clients. The DHCP server allows the client to request the IP addresses and other network configurations from the Internet service provider. This process eliminates the need for administrators or users to assign IP address to network devices one by one. Using this protocol, the network administrators will just set up the DHCP server with all the additional network information, and it will do its work dynamically. Both network switc
