To be able to manage certificates in vSphere 6.5, we'll see how to use the tool we have to manage the vCenter Server Certificate Authority. We must make the CA that brings the PSC a subordinate entity of our own CA of the domain and generate certificates in which we do trust and so not even the browsers will trust and other dependencies. At the end of the document, we'll look at how to change ESXi and vCenter certificates.
Continuing with the VMware vSphere series of posts 6.5, Today we will look at something quite important, Replicating virtual machines to our virtual infrastructure, How to protect ourselves against a disaster in our datacenter. We will initially configure the requirements and then we will see how to replicate a virtual machine and how to make a recovery or failover if necessary!
One of the great features that VMware vSphere has is Storage DRS, that as we can imagine, is similar to traditional DRS but with storage, This is, instead of distributing the count (CPU, RAM…), with Storage DRS we will be able to distribute the load of the datastores, balancing so much for performance (Latency to Datastore) and by space used. With this we will have fully distributed the load in terms of disk!
We will be able to continue with another automatic update process, and it is only once we have all the hosts updated to the version 6.5, We will need to update (in this order) VMware Tools and Virtual Machine Hardware. The latter perhaps more optional. We will do all this through Update Manager which, as we know, is embedded in the vCenter Server Appliance 6.5
As we already know, Update Manager is the VMware product that will keep the vSphere virtual infrastructure fully up to date. With UM we will be able to update the patches or versioning of ESXi hosts in a centralized and fully manageable way, as well as Virtual Machines or Virtual Appliances! We will see as an example how to update a host of the version 6.0 from ESXi to the 6.5 Update 1, for this, without moving from the chair, we will upload an ESXi image to Update Manager and install it to the hosts that need it!
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'.
In this post you will learn how to deploy a VMware vCenter Server Appliance 6.5, By following the steps in this document, you will be able to have a vCenter server deployed on a Linux appliance in a virtual machine to manage your vSphere infrastructure, both hosts and VMs! It is a second basic document in a series of articles to come! I hope that if it is not in this, The next documents will be useful to you!
This is the first document in a series of posts where we will look at how to perfectly deploy and configure a VMware vSphere platform 6.5, in this document we will look at the simple installation of the ESXi hypervisor, plus a brief walk through its basic configuration with the DCUI and we will access your Host Client to manage it as well as your virtual machines. We will continue with other documents that will make us grow and optimize our environment!
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…
In this document, we'll look at all the steps needed to be able to monitor an ESXi host, we will see the most common parameters and the values that we can obtain to have a controlled environment thanks to Nagios and Centreon! All the information we can obtain is amazing! In other documents we will see other information that we can obtain from vCenter and its VMs, Today the hosts are playing!
