VMware vCenter Server Appliance

One of the new features of vSphere 5 es la disponibilidad de un nuevo virtual appliance con VMware vCenter Server 5 in it, es una máquina linux por lo que ya quitamos la necesidad de tener un Windows consumiendo licencias para gestionar un entorno virtual de VMware de forma centralizada. Este nuevo appliance virtual llamado VMware vCenter Server Appliance (vCSA) nos ahorrará dinero en gastos de implementación, mantenimiento y sobre todo licencias Windows, en este documento veremos cómo podemos desplegarlo en apenas unos minutos (la instalación y configuración),

vCenter Host Agent Pre-Upgrade Checker

Antes de actualizar nuestra infraestructura VMware vSphere a la versión VMware vSphere 5 (nuestros hosts a ESXi 5.0) debemos ejecutar una utilidad que tenemos en el DVD de VMware vSphere 5, donde podremos comprobar sin paradas de servicio si nuestros host ESXi son compatibles para una posible actualización de versión (de VMware ESXi 4.x a VMware ESXi 5.0) gracias a vCenter Agent Pre-upgrade Check tool.

VMware vCenter HeartBeat

In this document, we'll look at installing and configuring VMware vCenter Heartbeat, this product allows us to obtain high availability of our VMware vCenter server in environments where it is critical, allowing application-level protection at all times, services, SQL Server if on-premises, Update Manager or if we have VMware View protecting it for use with VMware Composer. With this product we will have two vCenter servers, A primary one (active) and a secondary one (passive) where we can manually change roles (switchover) or in the event of a fall (failover) We will have high availability since the information is continuously replicated through a private network, This drop could be at the hardware level, S.O., Network Issues, vCenter application crashes or their dependencies.

Migrate VMware vCenter 4.0 32bit to VMware vCenter 4.1 (64bit) + Update Manager

In this document, we'll look at how we can upgrade our VMware vCenter environment 4.0 to VMware vCenter 4.1, eye! we will take into account that in the source installation we have the vCenter in a 32 bits and (As we know) vCenter 4.1 can only be installed in systems of 64 Bit, therefore we are going to have to migrate all the configuration of a server (x86) to another (x64). If the source server is already 64 bit there would be so much complication. Once we have updated vCenter and its components to the 4.1 we will now be able to update the ESX hosts(i) a 4.1.

Using Host Profile in VMware vSphere

One way to help us in the configuration of our virtual environment is to rely on one of the new features that VMware vSphere brings 4, the ability to use already configured templates to apply to all our ESX hosts, or for when we add a new VMware ESX host to our virtual community, we can apply the same configurations that one of our hosts already has.. We can create a template from scratch by configuring everything manually or get said template from one of our servers already configured perfectly (being able to edit the profile if necessary), and then apply it to the rest of the hosts that do not meet the requirements that we indicate. This is called the VMware Host Profile.

Using Veeam Backup & Replication to make backups and replicas of our virtual environment

This Veeam product called Veeam Backup and Replication, offers us the possibility of both backups and replication of our VMware virtual environment, for both VMware Infrastructure 3 How to VMware vSphere 4 (VMware ESX or VMware ESXi, depending on the license purchased, that the product is paid for, but very cheap). It will allow us to make backups of the virtual machines that we indicate in the location that interests us, We will be able to keep as many copies of the same virtual machine as we are interested in, as Veeam will store them incrementally. Personally, what I like is the replication, since the backup is given to us by VCB or VMware Data Recovery, replication can be carried out in another storage array that we have and the replicated virtual machines will be optionally placed in the VMware inventory, just like backups, We can have so many replicas […]

How to Upgrade VMware vCenter 2.5 to VMware vCenter 4.0

If we want to have the new VMware virtualization technology, vSphere, with the new version of VMware ESX hosts, we will need to update our VMware vCenter Server virtual infrastructure management server. And this will have to be updated before updating our ESX host to the latest version. This procedure shows the steps to upgrade a VMware VirtualCenter server from the release 2.5 to the 4.0.
