It’s not uncommon for different teams to be managing the virtual switch and physical switch configurations. This can make it very difficult to troubleshoot unless each configuration parameter has been gone through manually. There have been enhancements to the vSphere Distributed Switch over the past few years to address these operational challenges.
vMotion, as you may know, is the capability to move the state of a running VM from one physical host to another host without user disruption. It requires the two VMs to be on the same datacenter, in the same cluster; have hosts sharing the same storage, on the same LAN, on same Layer 3, on the same switch; and on the same vCenter — if you are still using vSphere 4.0! However, each newer version of vSphere has gradually “whittled down” the requirements of vMotion, and vSphere 6.0 has removed all but the “same datacenter” requirement.
Two terms that you will see most if you read IT forums today are “cloud” and “Software Defined Datacenter (SDDC)”; but what do they really mean? vSphere provides the capability to create an isolated compute (CPU and memory) environment for each of your applications. In fact, this has been true for years. Now, with integrated products such as VMware’s NSX and VSAN you can create an isolated, controllable and secure network and storage environment for each of your applications as well.
VMware recently released VMware vSphere 6.0 into the marketplace. The latest vSphere version is packed full of more than 650 technological breakthroughs! It’s more powerful, more flexible, more secure and more easily managed than ever before. In this series, Global Knowledge instructor, Bill Ferguson will highlight several features that make VMware vSphere 6.0 a game […]
I always tell my students that one of the main groups of facts that they should be studying for the test is configuration maximums, especially if they are higher than those of the previous version. Well, that means that “we” have some more studying to do now; because the configuration maximums that VMware announced for vSphere 6.0 have increased in just about every category regarding the design of clusters, hosts, and VMs.
High availability’s goal within VMware vSphere is to minimize downtime, not prevent it. This feature is available in all editions of vSphere except Essentials. It is designed to handle the failure of any or all of the following: Loss of a physical ESXi server. Loss of a virtual machine. Loss of an application within a […]
