QCOW2 and Row Difference In a KVM virtual machine, you need to select a format for the disk image, usually with two options, one in raw mirror format and one in QCOW2 format. RAW format is the original image , will be directly as a block device to the virtual machine to use, as the file inside the hole, it is hosted by the file system to manage, Linux file system can well support the characteristics of the hollow, so, If you create a 100G raw format

With a new computer, ready to install a dual system, Windows used to play games, Linux to write code. Dedicated to buy two 1T hard drives, want to use to build RAID0, using parallel I/O to improve the performance of the computer. Select the motherboard when selected to support the raid of the motherboard, MSI B85-g43 Gaming, can use MSI super RAID technology, but bought after found that the driver of this thing is EXE program, OH, the motherboard support is only a pseudo raid, can only be used

capacity forwarding characteristics. Data center switch must support Gaomi million card, that is, 48 million gigabit board, in order to enable 48 million Gigabit board can be forwarded across the line, data center switches can only use Clos distributed Exchange architecture. In addition, with the popularization of 40G and 100G, support 8-port 40G Board and 4-port 100G card is also gradually commercial, da

40g/100g era (the standard was released in June 2010, the technology has matured), we have no reason not to believe the arrival of the Wan Xiaotong cable era. In fact, cabling system, as an information and communication infrastructure, should take into account the development law of the network in line with Moore's law. For the data center, from domestic and foreign standards (Ansi/tia 942, EN 50173-5, ISO/IEC 24764, GB 50174-2008) are required to m
