Posted by Andrea Mauro on January 31, 2018
4.8/5 (10)

VMware vSphere 6.5 is the latest version of the enterprise server virtual platform from VMware, but the new beta it’s already there for testers. Actually the next version it’s (in the beta). If you are building a new infrastructure from scratch the latest stable version is probably the best choices (for most cases); but what about if you have an old environment and you plan to upgrade it?

5 Tips to Master VMware vCenter Server Appliance
Posted by Vladan Seget on January 23, 2018
5/5 (1)

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.

Nowadays, many VMware vSphere administrators manage their virtual infrastructures with VMware vCenter Server Appliance 6.5 (vCSA). This solution currently is a full-fledged alternative to the VMware vCenter for Windows which becomes a thing of the past.

For ones who use vCSA not that long, this post provides several procedures which simplify solutions’ daily use. Let’s have a look at how they may come in handy.

VMware vSphere APIs for I/O Filtering (VAIO) – how does it work?

VMware has recently released VMware vSphere APIs for I/O Filtering (VAIO), a handy document that highlights the VAIO I/O Filtering technology operational principles. Here, we shed light on them briefly and discuss how VAIO can be implemented in a production environment.

VAIO is a technology and an API providing the direct access to the virtual machines’ guest OS I/O Stream. VAIO is already employed in partner products for maintaining various tasks (i.e., caching write-back and write-through). VAIO is based on the Storage Policy Based Management framework, dedicated to managing virtual machines storages and set the storage rules.

Getting started with PowerShell and VMware vSphere
Posted by Romain Serre on November 2, 2017
5/5 (1)

Since some time, VMware provides PowerCLI which is a set of modules for VMware vSphere. Except if you were in a cave last 10 years, you should know that PowerShell is a powerful scripting language. Initially, PowerShell enabled to manage only Windows Workstation or Server but since sometimes, a lot of vendors make their own modules to manage their solutions (such as Veeam, VMware and so on). Moreover, PowerShell is available on Linux.

For my job, I always use PowerShell. I’m a lazy guy, and if I have to make something two times, I make a script. This is the same thing for VMware vSphere. In this topic, we’ll see how to connect to vCenter and some commands to start.

vSphere Upgrade Options

When it comes time for your vSphere upgrade there are many different approaches to how you perform the upgrades on your ESXi hosts.   An administrator who looks after a small cluster may update one way, whereas an administrator who looks after an enterprise with 1000s of hosts may opt to go another.  Also, depending on how your environment is deployed you might want to choose one method over another.  Factors such as a whether or not your hosts are managed by a vCenter server, whether or not they are members of a cluster – these things all impact the methods in which you chose to update to the latest version of ESXi.  Certainly, some methods are much more simplistic than others to perform, some offer more advantages when upgrading at scale, and some are more prone to user error – let’s take a look at each method of upgrading our hosts below and discuss the benefits and drawbacks of each…

3 Generations of My Homelabs
Posted by Askar Kopbayev on August 15, 2017

Sooner or later every single IT guy comes to the idea of having some lab. There are a million reasons why you would need a lab: learning new technologies, improving skills, trying crazy ideas you would never dare to try in the production network, you name it. Even though it is a work-related activity for most home labbers this is just another hobby for many of us.  That’s why people spend so many hours of their personal time building the homelab, investing significant funds into new hardware, thoroughly planning its setup, looking for a help in online communities or sharing their experience to help others. There is a whole universe of home labbers and I am happy to be part of this community.

In this post, I would like to share my experience with 3 generations of home labs I have had so far and the thoughts about next generation.

How to join VMware vCenter server appliance (VCSA) 6.5 to the Microsoft Active Directory (AD) Domain

VMware Photon OS has been the latest OS used for vCenter Server Appliance 6.5. This is the latest move from SUSE Linux Enterprise Server (SLES) as VMware wants to own the Operating system (OS) and manage its development cycles and patches releases.

Things that aren’t possible on Windows OS or SLES. That’s why VMware used Photon Linux and continues to develop Photon OS which is optimized for VMware platforms.
