vsphere hypervisor

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 p

Vsphere advanced features can be achieved only when vcenter server and shared storage are supported. Vsphere advanced features include vmotion, storage vmotion, vsphere ha, vsphere DRS, storage DRS, and vsphere fault tolerance. 1. vmotion Vmotion is a function that can be u

VMware requires enterprise customers to continue to use vsphere and renew their enterprise license agreement. Because VMware does not sell hardware, it relies on revenue from licensing, support, and services. That's why you work with AWS. Based on the cooperation agreement, AWS will provide hardware, and VMware will provide software, support, and services. 2016, one thing you can't imagine: VMware announces service in Amazon Web Service

High availability and dual-machine hot spares are the most important part of VMware vsphere 5.0, where high availability is not unique to vsphere, and enterprise use of high availability is for service continuity and data security. HA (High availability) is a group of ESXi server-based clustering features, the main purpose is when the virtual machine running host failure can be timely transfer of the host,

you can analyze the traffic of the entire virtual network, as shown in ). Think about it. You don't have to spend a penny analyzing the virtual network. You only need to adjust the settings of a vSphere virtual switch and install a protocol analyzer on the virtual machine connected to the vSwitch. Analyze virtual networks Why do you want to analyze virtual networks? In fact, the reason for analyzing the virtual network is basically the same as that

that the number of virtual machines on which the VM to which the database is installed should not be too large.7. It is recommended that the physical Nic of the VMware vSphere host be directly connected to a Gigabit Switch instead of a 10-Gigabit switch.8. We recommend that you upgrade to VMware vSphere5 immediately. 9. Database optimization everyone on the Earth knows that it is necessary to optimize databases on virtual machines or physical machin
