Haproxy compared to the use of LVS is much simpler, functional aspects are also very rich. Currently, Haproxy supports two main proxy modes: "TCP" is also 4 layers (mostly for mail servers, internal protocol communications Servers, etc.), and 7 tiers (HTTP). In 4-tier mode, Haproxy only forwards bidirectional traffic between the client and the server. In 7-tier mode, the Haproxy analyzes the protocol and can control the protocol by allowing, rejecting, exchanging, adding, modifying, or deleting

by as much as a small number of people guessing about 708 billion transistors, the core area of 300-350mm2 around. (Update: The number of transistors is 7.2 billion, the core area is still uncertain.) ) 　　thanks to advanced technology, GTX 1080 video card core frequency is very high, the base has 1607MHz, acceleration frequency 1733MHz , and GTX 980 is only 1126, 1216MHz, on the frequency of the increase of 40%, so GTX 1080 graphics card 9 Tflops floating-point performance is almost 80% higher

USB3.1 is the latest USB specification, which is sponsored by large companies such as Intel. The speed of data transfer can be increased to 10Gbps. Compared with USB 3.0 technology, the new USB technology uses a more efficient data coding system, and provides more than one efficient data throughput rate. It is completely backward compatible with existing USB connectors and cables. , and the related USB3.1 products have come into view, especially in th

load balancer device uses TCP buffering to establish extremely long requests and has a large response time.Haproxy Advantages1, Haproxy can be used as MySQL, mail or other non-web load balancer, we often use it as MySQL (read) load balancing;2, with a powerful monitoring server status of the page;3, Haproxy support virtual host;4, HAProxy can run full 10gbps-new benchmark of HAProxy at ten Gbps using myricom ' s 10GbE NICs (myri-10g pci-express), thi

I'll talk about Apple's Thunderbolt interface later. Thunderbolt is a technology developed by Apple in deep collaboration with Intel Corporation, which incorporates traditional PCIe data transfer technology and DisplayPort display technology. The Thunderbolt interface was applied to the Macbook Pro notebook in 2011 by Apple. Its main advantages are: Large bandwidth, fast transmission speed. After the transformation of the new version of the Thunderbolt 2 interface, can achieve two-way 20Gbps

transmission speed (up to 10Gbps), and more powerful power transmission (up to 100W). Type-c dual-sided pluggable interface is the largest feature of the support of the USB interface double-sided insertion, mainly for the more lightweight, more slender equipment (the future may be unified mobile phone plate interface, replace the micro USB interface). Now the most common USB Type C interface, do not distinguish between positive and n

USB3.0 Standards and Thunderbolt technology are a major step forward in the field of external connectivity. However, progress is always there, and recently Intel has claimed that it has made a major breakthrough in USB technology. This breakthrough is shocking, that is, the maximum USB output power from the original 10 watts to 100 watts. So how powerful is the USB Superspeed 3.0 with 100 watts of power? Take a desktop computer example, USB Superspeed 3.0 can support both a printer and two LCD

in the world's leading position, at the same time, Tyco is a 10G Ethernet standard Alliance member. 1998 Tyco designed and installed the world's first submarine optical fiber system using DWDM dense wavelength division multiplexing technology-"Tyco Global Network (TYCO)" to achieve 16*10gbps high-speed transmission, transmission distance of more than 500km, The system is currently the world's largest submarine optical fiber system, connecting the wor

a performance bottleneck. The failover module contains an alternate node (Standby node), where the standby node accesses the external storage of the failed node through the SAN storage network and takes over the programs and tasks that are running in the failed node. The Data Warehouse application module contains data Warehouse application nodes (Warehouse application node) and OLAP analysis nodes (Warehouse OLAP node) and a DS3524 external storage. Data Warehouse application nodes are used to

attenuation and fext. is more practical than fext,elfext, because as the length increases fext certain changes will occur, which means that the same cable at different lengths, the measured fext for different values, which can not measure the quality of the cable, but Elfext because of the introduction of attenuation this parameter, Makes the online cable test more practical, so the test report will often appear elfext rather than fext this parameter. With the increase in transmission rate, su

bandwidth of their downloads and internet computers so that the entire network slows down because of downloading. 9. Supports multiple connection modes. Now the network connection Way is various, the different connection way needs the different protocol support. Therefore, we can save a lot of trouble by choosing a router that supports a variety of protocols. Today's broadband routers generally support TCP/IP, PPPoE, DHCP, NAT, ICMP, SNTP protocol, basically can meet the family commonly used A

network adapter that is used only for iSCSI and TCP traffic to reduce load, meaning that iSCSI traffic control is distributed. Modern iSCSI is already capable of handling bandwidth data up to 10Gbps. One of the benefits of iSCSI configuration is that it is more economical than traditional FC networks. But that's not always the case. When many servers send requests to and receive results from the storage process, you can quickly discover how much traf

function, supports VLAN division, and provides redundant power interface. Although for layer-3 Switch, DES-3326 performance in general, support expansion slot is relatively small, but the low price is also in exchange for good cost effectiveness. DES-3326 switches are suitable for medium and small network core layer and large campus network convergence, providing Gigabit Ethernet modules can be connected to high-speed backbone network, to effectively alleviate network bottlenecks.

Can I access the Internet? Can I use a network printer? DTX-NSM network service module can provide answers. At what rate can the network be connected?
