VMware ESXi: Shared Disk Between VMs In some cases (as a rule in clustering scenarios) it may be necessary to share the same disk between 2 (or more) virtual machines (VMs). The most optimal way is to use the vmdk disk physically located on the shared storage or locally on the ESXi host. If you want to use shared drives on different ESXi hosts, you can only use the shared storage (datastore). Suppose the shared external storage (connected to each ESXi host using iSCSI or Fibre Channel SAN) have already presented to all VMWare ESXi hosts, which are running the VMs you want to add a shared virtual drive. On both virtual machines you need to add a new SCSI controller. VMware: Shared disk between virtual machines In the vSphere Client inventory select first virtual machine (Node 1), right click on it and select  Edit Settings To add a new virtual device select  SCSI controller  in the dropdown list and press  Add  button. As a type of SCSI contr...

⇚============================================================================================================================⇛ Time Configuration for a Virtualized Domain Controllers Today we will talk about some of the features of time configuration on a virtualized domain controllers. Typically, the time synchronization scheme in the Active Directory domain is as follows: The PDC emulator is the main time source on the domain and must be configured to synchronize time with the external time source; All other domain controllers are synchronized with the controller that owns the  PDC emulator role ; All member servers and workstations synchronize their time with the nearest domain controller. Tip . For more information about configuring NTP time in a domain, see the article  Configure NTP Time Sync using Group Policy . For example, this is how the time settings look on our virtual domain controller. As you can see, it uses group policies to configure time se...
