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 create a virtual machine on the ESXi server to provide external services. If the vCenter component is used together, more and better functions will be supported. ESXi also supports hardware virtualization at the kernel level. The virtual servers running in it have no less performance and stability than ordinary hardware servers, and are easier to manage and maintain. VMware vSphere 5.1 provides the following versions: Standard, Standard with Operations Management, Enterprise, and Enterprise Plus. Each vSphere version corresponds to different features, and the price is also different. VMware vSphere 5.1 has added some new features, including: 1. Larger virtual machines-the number of more advanced versions of virtual machines has doubled. Virtual machines now support 64 virtual CPUs and 1 TB of virtual memory (VRAM ). 2. New Virtual Machine format-In vSphere 5.1, the new Virtual Machine format (9.0) features include support for larger virtual machines, CPU performance counters, and virtual shared graphics acceleration (GPU) designed to enhance performance ). 3. SE Sparse Virtual Disk: this Disk format is mainly used on the View Composer to quickly create Virtual machine images and subsequent snapshots by means of linked copies (linked clones, space Efficient Sparse Virtual Disk can be used to save Space. In addition, the space that is no longer used after the data is deleted by the virtual machine operating system can be recycled, and the granularity of the block configuration can be adjusted based on the needs of different applications, the default Sector Unit of the Virtual Disk block on ESXi is 4 kb, And the Redo logs and snapshot accessed by the link copy are 512 bytes. If SE Sparse Virtual Disk is used together, you can also set the unit of each slice to 4 kb. 4. remote Replication of virtual machines-Replication is a feature provided by vSphere 5.1 in many versions (originally part of vCenter Site Recovery Manager 5.0 ), A virtual machine that is running on one local ESXi host can be continuously copied to an ESXi host in another place. It will store the VM in a local cluster or on another platform, create a copy, and this data source will help you quickly restore the virtual machine. Compared with restoring a VM from backup data, restoring through vSphere Replication takes less time, and does not rely on the complex remote Replication settings of the storage device. In addition, vSphere Replication can also be set to remote Replication based on each virtual machine, with great elasticity 5, single I/O Virtualization (SR-IOV) support-supports SR-IOV Performance Optimization for complex applications. 6. vSpherevMotion-enhanced vMotion (zero downtime migration) does not need to share the advantages of storage configuration. You can apply this new vMotion function to the entire network. 7. vSphereDataprotection-the new backup and restoration tool replaces the original vSphereDataRecovery8, the improved distributed switch-network running status check, the configured backup and restoration, rollback, and reply, LACP supports 9. vSphere Web Client-vSphere Web Client is now the core of the vSphere management interface. This new, flexible, and powerful interface simplifies vSphere control and supports quick navigation, custom marking, and enhanced scalability, in addition, you can use Internet Explorer or Firefox for login management. 10. vCENTER single-point logon-greatly simplifies vSphere management. The management platform allows you to log on to all vCenter instances or layers at one time without further verification. 11. The emergence of vCenter Orchestrator-Orchestrator simplifies the installation and configuration of a powerful workflow engine on the vCenter Server. In addition to improving ease of use, you can also directly start a new vSphere Web Client. Note: In this experiment, two ESXi 5.1 hosts are deployed using the PXE network startup method. Both ESXi hosts have an Nic, And the CPU is 64-bit and the model is the same. virtualization technology is supported, with 8 GB memory-1, stop the DHCP service of the router in the network first to avoid affecting the PXE tool deployment. 2. Prepare a Windows Server 2012 virtual machine named DC, install the AD domain service and DNS Service (kkfloat.com), and create the DNS reverse Region 3. Download The ESXiPXE tool provided on the network from the DC Server, this tool allows you to easily start and Deploy PXE networks (of course, you can also use vSphere Auto Deploy to Deploy them ). decompress the package to generate an ESXiPXE directory, create an ESXi subdirectory under the directory, and then add it to the ESXi5.1 installation disc, copy all the files on the installation CD to the ESXi directory and find the esxipxe.exe directory on the dcserver. open the config file in notepad and modify "IPAddressStart", "IPAddressStop", "NetMask", "DNS1", "DNS2" according to the current network environment ", prepare tool to start network deployment service 5 start two hosts preparing to deploy ESXi 5.1, configure to start from the NIC, download ESXi5.1 from the network to start the installation process, and configure and install according to the steps, (Note that the IP address of the host (214.214.51.64, 214.214.51.65), host name (esxi1.kkfloat.com, esxi2.kfloat.com), and DNS (214.214.51.41) are configured )) (resources are limited. The video cannot be recorded during the installation process of the physical host. Use a virtual machine to test it.) 6. After the two ESXi hosts are installed, log on to the DC Server and create host records and reverse lookup records for the two hosts on the dns console, test network connectivity 7 re-enable DHCP for routers in the network 8 prepare a Windows 7 virtual machine named Clt-7 and add it to the domain kkkfloat.com, then install the VMware vSphere Client software in the virtual machine, then, use the VMware vSphere Client to connect two ESXi hosts to test whether they are normal.
