After an afternoon plus one night, finally put the reptile code to write well, behind there are many want to improve the place (for example, data storage with Redis, use multithreading to speed up, crawl pictures, subdivision data, etc.), to be free to make changes, the following is the specific steps and ideas: tools:pycharm,Google chrome developer tools, Fiddle2 Platform: Python3.4 First , enter the public comments the default

A shared folder is set up on your computer, but you do not want to have unlimited file storage on your local area network. Using disk quota management, disk space is blocked when a user holds a file that exceeds the specified space. You can follow these steps to set up. 1.NTFS volume is established, in Explorer, right-click to select the volume for which you wa

Preface Stored programs are mainly stored in the host and enterprise-level storage devices. If these storage applications are moved to the Storage Area Network SAN, this will greatly reduce the overall storage management costs for

. In recent years, the new San over CWDM (coarse wavelength division multiplexing) solutions, such as the Ciena CN 2600 products, provide the best transmission performance, but also solve the high cost of DWDM, in the area of storage expansion has been widely used. SAN over IP solutions enable organizations to leverage their existing virtual private network (VPN

Network virtualization is now a hot topic, and major manufacturers are scrambling to grab this cake. Technologies involved include virtual Emulation for NICs, I/O pass-through, SR-IOV), virtual access technology for networks VN-Tag/VEPA), covering network switching VXLAN/NVGRE ), and Software Defined network SDN/OpenFlow. For details, refer to the blog "

We know that NFS is a network file system and plays an important role in network protocols. With the development of network storage. It has made great progress in this area. Here we will introduce the application of nas nfs in VMware. NAS is a simple

0 Introduction With the advent of the information society, how to make small and medium-sized enterprises users can also invest a small amount of money in the data storage to obtain greater storage space and data management? Networked storage is a better solution, and iSCSI technology is emerging, narrowing the distance between SMEs and sans (

Introduction iSCSI (Internet SCSI) technology developed by IBM Research, is a hardware device used by the upper layer of the IP protocol can run the SCSI instruction set, which can be implemented on the IP network to run the SCSI protocol, Allows routing to be routed on such high-speed Gigabit Ethernet. iSCSI technology is a new storage technology that combines existing SCSI interfaces with Ethernet (Ethern
