Installing VMware ESXi 6.5 + DCUI + Host Client

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!

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…

Nagios – Checking snapshots on VMware virtual machines

In this post we will see how Nagios can help us monitor the existence of snapshots in our virtual infrastructure, Everyone knows the danger of having snapshots or leaving them for long periods… Hanging backups that leave half-baked snapshots… To combat this, We'll automate a periodic check-in with a great script!

Nagios – Monitoring our ESXi hosts

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!

Upgrade to ESXi 6.5 and pre-upgrade checklist

In this document we will be able to follow the steps that will allow us to update our ESXi host to the latest version, the 6.5. See 3 Upgrade Options, A first, Surely the most used by everyone, which is through a package that allows us to update offline, by command line in the fastest way; a second way that is similar to the previous one but online, downloading the updater directly from the VMware website and finally the traditional, The simplest, which is via CD, USB or iLO!

Scheduling ESXi 6.x configuration backups

While it's interesting to back up our ESXi setup… Why don't we schedule it? I leave you a couple of options that will surely fit you to have updated backups of the ESXi configuration.

Migrate vCenter Server to vCenter Server Appliance 6.5

When migrating to VMware vSphere 6.5, we have the possibility to decide if we want to continue with vCenter Server installed under a Windows Server, or leverage and migrate to Linux with the vCenter Server Appliance. In this document we will see the advantages and how to proceed!

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.

Migrating from vCenter Server to vCenter Server Appliance

With this great tool from VMware Labs, we will be able to migrate our vCenter server installed on Windows to the VMware vCenter Appliance linux appliance, will migrate the SQL Server database to vPostgres and all major services, interesting, isn't it? We will finally be able to easily migrate vCenter from Windos to Linux, with the savings that come with it on licenses!
