communication technology and large-capacity data centers. To cope with the challenges of big data, the application of cloud computing virtualization network technology is an inevitable technological development trend, facing massive data storage and data processing, to improve resource utilization efficiency and data analysis and computing capabilities, data centers will use a large number of virtualized cloud computing technologies, including server virtualization technology, network virtualiz

network. Although the three-tier network configuration is complex, it can be deployed automatically through the Controller. As long as the port of the network device is connected through a cable, all network configurations are automatically deployed. For example, in a VXLAN network, as long as the network device is configured with a route to connect to the Controller, the interface address is connected, and the Controller automatically sends a VXLAN configuration when it perceives a port UP wit

Press "Enter" button to enter the Raid editing window, in the editing window can set the mode of RAID, it is important to note that many RAID cards for the user-provided mode is used in the storage mode expression, wherein "Stripe" Bar storage is RAID 0 mode; " Mirror "represents RAID 1, while" Mirror/stripe "represents the raid0+1 mode. The user can switch the RAID mode using the SPACEBAR, select "Mirror/stripe" mode, and set the four drive in the channel to "Y" status. After setting is comple
multiple businesses. At the same time, the high-speed programmable hardware FPGA manufactured by the current hardware technology can process 40g data streams of the packet header, thus providing the possibility of multi-service support. Gangwan network Co., Ltd. saw this possibility and found the theoretical basis for building the hardware platform. After three years of painstaking research, at last, ASIC + FPGA + TCAM is implemented to achieve high-
address transformation mechanism, also known as the Fast Table (TLB), which is used to store the page table entries currently accessed. The address transformation mechanism with a fast table is shown in four. Because of the cost of the relationship, the fast table can not be done very large, usually only 16~512 page table items.The above address transformation mechanism is very good for small and medium programs, fast table hit rate is very high, so there will not be much performance loss, but
