Server 2016 is out for a while now, so I thought it will be a good time to write about one of the new features that Microsoft implemented in their latest server operating system for which I was really hopping for. They called it Cluster OS Rolling Upgrade.

Join VCSA 6.x to an Active Directory Domain

We started deploying our VMware vCenter Server Appliance (VCSA) either with an embedded PSC or an external one, and once the deployment was finished we noticed that we can’t use our Active Directory domain credentials to log in into vCenter. The only way we can get in is by using the

VMware vSphere 6: Configure VMCA as a Subordinate CA

I must say that VMware has done a great job with the vCenter server appliance. Not only is easy and fast to deploy but it also gives us the ability to change its certificate using a nice menu screen that they called it vSphere 6.0 Certificate Manager. As you know, changing certificates

Deploying the VMware vCenter 6.0 Appliance (VCSA) with an External Platform Service Controller (PSC)

As you know, starting with vSphere 6.0 VMware introduced the Platform Service Controller (PSC) which changed quite a bit how their Data Center applications interact with each other. They are all tight to the PSC, because the PSC is the one that deals with the identity management, generation of SSL certificates, license keys, global permissions,

Deploying and Configuring VMware vSphere Replication Appliance 6.0

For most companies backups are not enough, because in case of a disaster they need to be online as fast as possible in order to serve clients and not loose revenue; so they built secondary datacenters for disaster recovery and bought expensive storage to manage and replicate VMs from the main site (production site) to …

Upgrading from VCSA 5.x to VCSA 6.0 with an Embedded Platform Service Controller (PSC)

Since version 6 of the VMware vCenter Server Appliance (vCSA) has performance improvements, stability and new features, your management or design team decided it’s time to upgrade your existing vCenter server infrastructure running on version 5.x. I call this upgrade since VMware calls it the same, but it’s actually a migration. You are basically deploying …

Deploying VDI using Windows Server 2012/R2

In a previous article I talked about publishing desktops and applications to users by creating RDS Session Collections. In most cases that method works great, but as you know, there are users in the company that need dedicated resources to their virtual desktops, and by using RDS Session Collections we can’t separate those resources since …

Deploying the VMware vCenter 6.0 Appliance (VCSA) with an Embedded Platform Service Controller (PSC)

Starting with version 6, VMware has completely changed the way we deploy the vCenter server appliance (vCSA). If in older versions we had to use the import template wizard from the vSphere client, now we have a web interface just for that. I can’t say which one is better because it’s kinda the same thing, …

Installing Remote Desktop Services (RDS) in Windows Server 2012/R2

In previous versions of Windows, deploying a RDS infrastructure was a little bit difficult, but starting with server 2012/R2 this was simplified a lot. Not only you have a single central console from where you manage all your RDS infrastructure, but you can also install all the RDS roles remotely from this console.

Deploying and Configuring VMware vCenter Server Appliance 5.x

VMware vCenter Server Appliance or vCSA for short, has greatly improved compared to previous versions, and in version 5.5 which I’ll discuss in this article some most wanted limitations were lifted. Now it can support up to 100 vSphere/ESXi hosts and 3.000 virtual machines with the integrated vPostgress database, which is more than enough for …
