Re: VMware vSphere Client For Mac OS X 10.9 ebob9 Mar 30, 2015 4:43 PM ( in response to Cyberfed27 ) There was a native client for OSX in preview release of vSphere 6, but it was removed for the final release and no longer works. The VMware Feature Walkthrough site provides step-by-step guidance for installing, configuring & managing VMware products & solutions. The damaged virtual machine then restarts and synchronizes to restore fault tolerance. Fault Tolerance limitations. This supports VMware's Fault Tolerance component of VMware vSphere. Will it be 'bundled' with VMware Infrastructure, or just VMware Fault Tolerance is a process where a virtual machine, called the primary vm, replicates changes to a secondary vm created on an ESXi host other than the one hosting the primary vm. Fault Tolerance (FT) increases availability of virtual machines by creating an identical copy of the production VM that is continuously updated and ready to replace the original VM in the event of downtime. This four-day, hands-on training course is an introduction to VMware vSphere®. When VMware FT is enabled on a virtual machine, a copy of the Primary VM is automatically created on another host and the two VMs are - 2 VM will use High availability. [Read more] Fault Tolerance Use Cases Thank you to our partners at VMTraining for the VMware fault tolerance demonstration! You should get a warning message that you can't use thin provisioning and the VMs won't use DRS and a memory reservation will be set.
