5 Tips to Master VMware vCenter Server Appliance
Posted by Vladan Seget on January 23, 2018

VMware vCenter server appliance is evolving with every major release of VMware vSphere Suite. The product, which manages the whole vSphere infrastructure, can be either installed on a Windows server or deployed as pre-configured virtual appliance called vCenter Server Appliance (VCSA).

Over several VCSA releases, VMware managed to make this product equal to the Windows-based one, and it pushes the development even further so now the Linux based product has more features than the vCenter server installed on Windows.

However, many VMware admins are also Microsoft guys and like the graphical user interface to work with. That’s why today we’ll have a look at 5 Tips to manage this appliance. We won’t go into the configuration steps within this post as this has been documented many times.

Posted by Vladan Seget on June 15, 2017

Many IT administrators or virtualization guys runs their homelabs at home. It is a good way to learn new technologies, be able to break things in a lab to get stronger skills.

It is sometimes a challenge, to squeeze as much RAM as possible from it. The main challenge is always a memory utilization. VMware VMs are getting memory hungry all the time and they are not “optimized” for Homelab use, but rather for production environments. Yes, it is the main purpose of those VMs after all.

One of the large VMs, but most critical, is VMware vCenter Server Appliance (VCSA). This product is becoming very popular within VMware communities and it is very easy to setup. Today we will have a look if we can do some optimizations and some “tweaks” to make it less memory hungry.

VMware vCenter Server Appliance (VCSA) and after install tricks
Posted by Vladan Seget on April 10, 2017

It is not new that VMware vCenter Server Appliance (VCSA) is a very popular option, especially for small businesses which can save money on an additional Windows Server license.

It is a prepackaged and preconfigured virtual appliance with PostgreSQL database, vCenter server 6.5 components and also (in case you deploy “all-in-one” VM) Platform services Controller that contain all of the necessary services for running vCenter Server such as vCenter Single Sign-On, License service, and VMware Certificate Authority.

The VCSA is running Photon OS which is a VMware own lightweight distribution, optimized for fast booting, security, and scalability. During a long time, VMware was using Suse Linux Enterprise Server (SLES) distribution, but the fact that VMware did not own the stack was a break to faster development.

VMware vSphere 6.5 – What to be aware of before upgrade?
Posted by Vladan Seget on December 6, 2016

VMware vSphere 6.5 has been released few weeks back and many users would like to hit the upgrade button. Not so fast. In this post I’ll talk a little bit about what to consider before upgrading to vSphere 6.5. One of the good news is that there are no new license keys needed for vSphere 6.5 so if you’re currently on vSphere 6.0 you don’t need to enter new license keys.

Planning is a pain, but it is necessary step. Also, playing with Firmware on your physical NIC cards and applying proper firmware-driver combination is a hard reality before even thinking going further…. I have experienced that recently when upgrading my pNICs to proper firmware/driver combination (Those were the x710-da2 Intel Hyper converged 10GbE adapters).

Below you’ll find few points which are essentials to every IT admin.
