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 figure 1), primarily for cloud data center ser

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.
