Integrating vCenter Server Appliance 6.5 and its ESXi hosts in Active Directory

In this post we will be able to see how to configure authentication against our Active Directory in the VMware vSphere virtual platform. We'll enable it on the vCenter Server Appliance and ESXi hosts, so that you can assign access permissions to Active Directory users or groups. And so instead of using the default credentials (As we do wrongly); each employee will use their DA account, with the privileges that he should have, It will also be useful to see 'Who does what'.

Nagios – Monitoring our VMware vSphere VMs

In this document we will monitor interesting elements that we will obtain from our VMware vSphere-based virtual machines, centralizing in Nagios the checks we do to manage its values, Get alerts or generate graphs of your consumption. We will see, among other checks, in the VMs obtaining the values of their CPU Ready, CPU Wait, Memory Overhead, Memctl, Balloning, Write or read IOs…

Extending a shared virtual disk into multiple VMs

I leave you this post because a client has asked me to do it on several occasions and so I leave it for you 😉 too If we need to expand a virtual hard drive (Vhd) that is shared across multiple virtual machines, typically for cluster use, we will remember that we have the SCSI controller in Bus Sharing and that the disk is created in Eager Zeroed! We will follow these steps to expand this album.

Upgrade ESXi hosts to 5.5 with Update Manager

Continuing to upgrade your environment to vSphere 5.5 with Update Manager, after upgrading vCenter Server and other components, the next step will be the upgrade of the ESXi hosts to the version 5.5. As we saw in a previous document, we can also perform the update manually. We will be able to directly migrate the ESX 4.x to ESXi 5.5 or upgrade the ESXi 4.x or 5.x directly.

Upgrade a vCenter 5.5 and vSphere Update Manager 5.5

Well, Another way to upgrade to the vSphere version 5.5 will be to upgrade our vCenter Server (Windows-based), later we will update Update Manager and with it the hosts in an orderly way (to put an end to VMTools in virtual machines and raise vHD if interested). This is usually found in somewhat more complex environments, where neither vCSA nor update management is used.
