1. What is VirtualizationVirtualize a computer into multiple logical computers with virtualization technology. Each logical computer can have a different operating system that is independent of each other and does not interfere with each other.2. What virtual machineA software platform that runs operating systems and applications like a physical machine3. The current mainstream virtualization productsVmwareMicosoftCitrixRedHat4.KVM

Chapter 4 Distributed (network) storage systems4.1 Glusterfs IntroductionThere is no detailed description of how Glusterfs works, and if interested can go to the official website to learn more about the principles and deployment.For this test environment, the underlying distributed storage system primarily provides ser

ISCSINetworked Storage ServicesFirst, Theoretical PartISCSI the conceptISCSI, or internetscsi, is a standard developed by the IETF for mapping SCSI blocks to Ethernet packets. Fundamentally, it is a new kind of storage technology based on IP Storage theory, which combines SCSI interface technology and IP network tech

reliable transmission of large amounts of data between host systems (initiator initiator) and storage devices (target targets) on TCP/IP networks.The topology of the complete iSCSI system is as follows:iSCSI simply means that the SCSI instructions are encapsulated in the TCP/IP protocol and transmitted over Ethernet. ISCSI enables the transfer and operation of the SCSI protocol over an IP

Security comparison of network disk data We are here to do the data security aspects of the test, that is, considering that ordinary users in the day-to-day use of computers, sometimes because of the wrong operation of some important files mistakenly deleted, but still can be recovered through the Recycle Bin, backup file recovery, and other ways to restore the file. Then the network disk data from the PC

The storage area network (SAN) is a high-speed network or sub-network that provides data transmission between the computer and the storage system. A storage device is one or more disk d

multiple servers, after searching, calculation and analysis will be processed results back to the user. Through this technology, network service providers can process tens of millions or even billions of messages in a matter of seconds. Virtualization is a generalized term in the field of computers, which usually refers to computing components running on a virtual basis rather than on a real basis. Virtualization technology can expand the hardware ca

Article Title: logging on to the network storage stage In Debian Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

Hi everyone! Today, we mainly learn about the data storage mechanism of Android. There are four main methods. Today we will introduce shared preferences, files, and network. Next we will introduce the SQLite method. As an example, it is easy: It toilet experienceOne day, I went to the computer city and suddenly felt a stomachache. Bad. You need to go to the bathroom.Before arriving at WC, I looked up a

the TCIP/IP protocol for communication. Therefore, you only need an Ethernet network to connect the two ends of iSCSI, the storage performance of iSCSI is directly related to this Ethernet, so it is best to use a Gigabit Ethernet switch in the iSCSI network. Poor network equipment will seriously affect the performance

Yesterday, a linux system was deployed for a customer. The server itself had only GB disks as the system disk. All data is stored in network storage, and network storage (iSCSI) needs to be mounted to the local device. The configu
