After playing ESXi for a few days, the virtual network configuration can be easily summarized in some circles. At present, it cannot be said that it is very proficient, but it can be accumulated. Network deployment Diagram The following is a simple server network deployment diagram. Three networks are planned in the topology. One is the Internet: WAN, and the other is the office network: LAN (access in the office environment ), one is Private LAN (se

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 configuration process is summarized as follows: Create iSCSI on Windows server 2008 R2 Due to remote deployment, I don't know what network storage is like. I asked the customer for a Wind

VMware vSphere server virtualization Lab 1 ESXi 5.1 is a core component of vSphere, similar to Windows Hyper-vServer and Citrix XenServer, it is a system that can be installed and run independently on the supervisor. Therefore, unlike VMware Workstation, it no longer depends on the host operating system. After ESXi is installed, You can remotely control the connection through the vSphere Client, and then cr
Because the test needs every it cock silk will need one or two test server, but not enough for a machine to install a system ah, so it is necessary to assemble a high-performance testing machine to do virtualization, let's say a DIY ESXi virtualization server (of course, this does not consider server security issues)!First, the choice of hardwareCpu:xeon e3-1200 V3 Series * 1 pcs (BULK)Memory: Kingston DDR3 8G * 4HDD: Kingston 120GB + 250G SSDMotherbo
