One day, any VMware administrator may require the so-called “support bundle” which contains log-files, diagnostic information, and performance metrics. Taken together, these parameters allow troubleshooting VMware vSphere. The bundle provides VMware GSS (Global Support Services) the insight into virtualized environment configuration which allows them to resolve issues, when a client submits a support ticket with this bundle attached.

Apart from that, the bundle comes in handy, for example, while analyzing the reasons of the “pink screen of death” (PSOD) in ESXi environment and other errors.

This article discusses retrieving the support bundle for VMware vCenter servers (be it Windows or vCenter Server Appliance, vCSA) and VMware ESXi.

Before we go deeper, here’s a small note: the support bundle can bloat to 300 MB, depending on what it contains, the frequency of infrastructure configuration changes, and how long ago the last change has been made.

RAID-Today

You may have heard that RAID is no longer applicable for enterprise storage: that it’s time had passed. RAID has dominated enterprise storage for decades and, while not a hot topic of conversation today, it remains a key strategic approach for businesses to consider.

To some degree, it is true, RAID is no longer the singular answer to enterprise storage that it once was.  For decades it was unchallenged as a technology and as an approach, and so reigned alone – a foregone conclusion in a giant sea of storage.  Today, RAIN has joined the space and is a viable alternative to RAID in many scenarios.  But just because RAIN is newer and the darling of storage conversations does not mean that RAIN will simply displace RAID nor that RAID’s position of importance has been eliminated.  Not at all.

Whip your Hyperconverged Failover Cluster into shape automatically and with no downtime using Microsoft’s Cluster Aware Updating
Posted by Paulsen Muzari on March 14, 2018

Some admins prefer the Cluster updates to be done automatically. To do so, Microsoft designed a feature to facilitate patching of Windows Servers from 2012 to 2016 that are configured in a failover cluster. Cluster Aware Updating (CAU) does this automatically, thereby avoiding service disruption for clustered roles.

In this article, we are going to take a look into how we can achieve this assuming that Cluster is built with hyperconverged scenario and StarWind Virtual SAN used as a shared storage. Before going in the steps to set the CAU, we will investigate this scenario.

Replacing a Veeam Agent for Windows host while preserving existing local or share backups

starting Veeam Agent for Microsoft Windows service - runing a full back up

Imagine you have a server with data source volumes that are backed up to local (or a share) target backup volumes with Veeam Agent for Windows (VAW). You might or might not backup the OS as well. That server is old, has issues or has crashed beyond repair and needs to be replaced. You don’t really care all that much about the server OS potentially but you do care about your data backup history! You don’t want to lose all those restore points. Basically, we try to answer how do you replace the backup server when it’s a local Veeam Agent for Windows 2.1 deployment.

How do you do this?

VMware Horizon FLEX. The architecture and the key features
Posted by Alex Samoylenko on October 20, 2016
4.5/5 (2)

As far back as 2 years ago at VMworld Europe 2014 conference VMware announced the release of the VMware Horizon FLEX solution. It is a virtualization platform for desktops, which allows running virtual machines locally on users’ computers, both on Mac and with Windows, while connection to the company’s datacenter isn’t available. At the same time, the virtual machine utilized by the user can be Windows-based or have guest OS Linux inside.

Many virtual infrastructures administrators still remember that before VMware had VMware ACE and VMware View Local Mode products, which passed long ago and now have been replaced with FLEX technology. Since VMware Horizon FLEX 1.9 version, as well as the new versions of Workstation and Fusion desktop platforms, has been released just recently, let’s look closer at the FLEX solution and consider its key features.

VMware Horizon FLEX isn’t a standalone product, but a mixed technology based on three solutions:
