Wi-Fi Alliance announces the completion of Wi-Fi direct standard, so that Wi-Fi devices do not need to connect to traditional home, office or hotspot network, you can achieve mutual connection, the relevant equipment certification work has begun, through the certification of products will get Wi-Fi certified Wi-Fi Direct identification. What is a Wi-fi point-to-point connection? According to Edgar Figueroa, executive director of Wi-Fi, the interconnection of Wi-Fi devices can be achieved anywher

in applications to provide customers with an application reference. If customers' key applications require the ultimate performance, you can use the PX series. If you think that the performance is sufficient, and pay more attention to the economics of storage, you can choose the SX series. Although there are many types of flash storage products and their application scenarios vary widely, they can be applied to both the server side and the storage array side, but for fusion-Io, it focuses on th

. Gpu mc is usually 32bit, while ddr3 MC is usually 64-bit. We can use the following formula to calculate the GPU memory bandwidth: mclk * datarate * channelwidth * channel number/8/1000, simplified: mclk * 4*32 * channel number/8/1000. If the video card has 12 Mc channels, the memory bandwidth is 1375*4*12*32/8/1000 = 264 Gb/s. Other PCIe devices and hosts are connected to the MMU (Memory Management Unit) through the

Q: After backup in the recovery system, the NIC number becomes eth1 instead of eth0A: Modify the Udev rules file, delete the 70-persistent-net.rules file under the/ETC/UDEV/RULE.D directory, and then restartFor some special applications, such as a USB stick Linux system, after deleting the file, you can create a folder with the same name in the directory mkdir 70-persistent-net.rules so that no Udev rule file will be generated after each boot.Q: Set multiple IP addresses for a single NICA: You n

For example, in your configuration, each LUN has 4 disks, and if your queue depth is defined as 16, then the maximum number of I/Os that the entire system has at the same time is 64 (4 disks * 16 maximum I/O values per disk);The queue depth is the number of commands in the command queue that are hosted on a single device.The queue depth is the larger the number represents, the more tasks you want to process, the more concurrentHBA Queue Depth refers to the

The transmission protocol is an optical fiber channel protocol, which is generally connected to an optical fiber channel switch through an optical fiber cable. Interfaces can be divided into optical ports and electrical ports.
