Objective In the 3D computer room data Center visualization application, with the continuous popularization and development of video surveillance networking system, network cameras are more used in monitoring system, especially the advent of high-definition era, more speed up the development and application of network cameras. While the number of surveillance cameras is constantly huge, in the monitoring s

court police officer must have at least five information points to meet the basic requirements. Considering the distribution of the Office and the functional problems of the room, it is necessary to enlarge the backup at to meet the needs of use, that is to say, a court of about 100 people should be deployed in the office area. In addition, in the public area of the court, that is, the trial area, in order to meet the needs of future construction of the Science and Technology Court, each court

Build your own GIS data center Author: Beijing competing upstream technology Source: www.2first.cn updated: Views: 1022 In the new curriculum reform, the geography teaching course has a 3 S (gis gps rs) content, and GIS-assisted geography teaching has an incomparable advantage in other ways, these indicate that GIS is be

server to a virtual environment to conserve the free server resources at the disaster recovery site may be easy to accept. Use the Infrastructure virtualization tool to move the physical environment to a smaller virtual environment at the disaster recovery site, including all the correct storage area networks and LAN connections. This will not only reduce the time to restore to the Dr site, but also reduce the cost of the idle server. In fact, if the Dr site is another office in the organizatio

-latency link can greatly improve performance and reduce system overhead or additional capacity. Other protocols can also reduce traffic, such as built-in compression functions. SOA Users communicate through Simple Object Access Protocol (SOAP) and sometimes generate multi-mb xml messages, which can be compressed by themselves. This reduces the data capacity by 90%. When application software is developed within an enterprise, IT should make full use o

The formation of several newest Ethernet bandwidth technologies is not to set a new high speed, but more to push such network protocols into nearby markets, especially the data center market. The following describes the specific causes by introducing 25G, 50G, and 100G respectively. 25G The official draft IEEE 802.3 standard for 25G Ethernet will be finalized in 2016 (see f

is even the power to drive virtualization to boost mobility, such as using virtualization software on laptops and smartphones. IDC predicts that by 2010 the number of servers deployed worldwide will reach 45 million, providing a great opportunity for virtualization technology that enables server consolidation, but there is one more problem to be solved, that is security. However, at present, the enterprise may not have too much need to consider security issues, integration is the most importa

When it comes to fiber optics, as a new generation of wiring products, it's faster and less disturbed by the outside world. But can optical fiber become the inevitable trend of next generation wiring, and replace copper? Although the fiber is more advantageous in speed and sec
