This post is for those of you who have the privilege of having Dell EMC Unity unified storage, Well, Well, in the post we will see how we can ensure the availability of this storage cabin, That won't fail, But just in case, Let's check all the components!
If we have a Dell EMC Data Domain as a storage solution for the protection of our data, and we want to make sure that your hardware and components are functional at all times, This is your post, we are going to monitor it with Centreon!
A Utility of Policies, that is not normally used and is easy to set up, we could regulate the hardware that users connect to machines by using an Active Directory GPO, controlling for example the use of USB devices.
One of the new features of VMware vSphere is the ability to give physical devices from hosts to virtual machines, This ensures that the driver of the virtual operating system, Directly access the physical device in question, The advantages of course is the increased performance of the device, as latencies are reduced. Latest version of VMware Tools required, it should also be taken into account that they can only be assigned 2 per virtual machine and 8 Per Host. And logically such a virtual machine will lose all the advantages of moving to other hosts, since we are assigning a physical device of a specific host. This is called VMDirectPath I/O.
This would be the last step for a successful migration of our VMware vCenter virtual environment 2.5 a VMware vCenter Server 4.0, once we already have the VMware vCenter Server in the version 4.0, we have migrated the VMware Update Manager to VMware vCenter Update Manager 4.0 and all our ESX hosts are already with ESX 4.0, we will be able to upgrade the VMware Tools to the virtual machines as well as then upgrade the virtual hardware version of the version 4 to the version 7.
VMware SiteSurvey and CPU Identification Utility are two VMware utilities that will show us the compatibility of our hardware to check if we can support VMware vSphere or ESX on our hosts 4.0 with all its features, since in order to use Fault Tolerance (For example) we must meet some CPU requirements.
