to hold virtual machine files → select clone options → Finish　　　　(2) snapshot : A "backup" of a point in time for a virtual machine vmdk file (Note: The backup here is not really a backup, because the original VMDK file is not backed up), you can restore the virtual machine to a moment of snapshot to achieve system recovery, and create a snapshot file. Once the original vmdk file is corrupted, it cannot be resumed normally. Snapshots have parent snapshots and sub-snapshots, and it is believed t

When a snapshot is created, the virtual machine performs a read operation, and Hypervisor examines the snapshot vmdk to see if there are any chunks that have been read.If so, the block is provided for the virtual machine from the snapshot, and if not, the virtual machine needs to read the underlying VMDK. If there is only one snapshot, this is not a problem, but a repetition to read the VMDK.However, if a large number of snapshots exist, such as one per day within two weeks, then hypervisor need

A virtual machine with a snapshot may have an error when making an online storage vmotion, which will cause the VM to turn on the virtual machine again, with the following errors.650) this.width=650; "src=" Https://s3.51cto.com/wyfs02/M02/8D/B7/wKiom1im_NODALsEAAKPlkVjqZ8448.jpg "title=" 1653371960.jpg "alt=" Wkiom1im_nodalseaakplkvjqz8448.jpg "/>There are three ways to solve these problems:1.

Then through the host, data center to manipulate. This is the same thing that can be done with VMware vsphere Client management tools.

Eighth Chapter Integration Now that you know how HA works from the inside out, we're going to have to explain different points in Ha,drs,sdrs and other components or functions, and we think it's worth mentioning, although admitting that some of the information isn't mature enough, we think it's a very important part of the book. Ha and stateless ESXi Vsphere 5.0 introduces a very cow-snapping feature-stateless esxi, stateless ESXi means no boot dis

Now that we know the prerequisites for HA and how to configure ha, then we'll describe what components ha consists of, so keep in mind that these are still areas of high concern, and there are more to wait to see in the following sections, the figure below describes the clusters of two ESXi hosts and the key components of HA. The constituent components of Figure 4:ha As you can see, the ha of Vsphere 5.0 is composed of three major components Fdm H

VMware connects to shared storage in three different ways, San,ip sans (that is, iSCSI) and Nas (NFS). This article is not about the difference between the 3 and the SAN and NAS, please go to Google. Second, this article does not look at FC Sans, if your environment already has a SAN that supports MPIO and has enough storage space, try to make the most of it. Because many articles point out that Nas/nfs is an ideal medium for low I/O demand workloads

In the previous chapters, we not only introduce the isolation detection when the isolation response is triggered, but also introduce the effect of false positives. When the quarantine response is set to power off or shutdown, the host becomes isolated and HA restarts the virtual machine on the host. However, this also means that there is no proper redundancy. Isolated responses may not be necessary to trigger, and downtime should be prevented. To improve the flexibility of the network,

The Vsphere Deployment Series 02--Get StartedFirst, about server virtualizationCloud computing is a huge trend of the Times, server virtualization is the tidal stream of the river.Virtualization technology realizes the logical abstraction and unified representation of physical resources, through which it can improve resource utilization, and can deploy resources quickly and flexibly according to the change of user's business requirements. Currently, t

Differences between vsphere 5.0 and vsphere 4.x Vsphere5.0 is a major upgrade based on vsphere4.0,The following changes made on the basis of vsphere4.0 will affect the installation and setting of vsphere. Removed the service console. Esxi does not include the service controller. You can use the esxcli command in the esxi shell, the vcli command, and

The vsphere client is a client running on the Windows desktop that cannot be run in a Linux environment, and after vsphere5.0, VMware is gradually weakening the role of vsphere client, Many advanced features, such as enhanced vmotion, are now implemented only in the Web client.VMware's design trend is to replace vsphere
