I guess once you will read through this article you will also notice how this technology is shaped out of familiar building blocks, but what I also hope for is that you will get a grasp of what is AlwaysOn, and get a basic understanding of how it works. I will fully cover installation and configuration of SQL Server AlwaysOn environment (using new and shiny SQL Server 2017) in my next article while focusing on technology overview here.

Generating a Support Bundle: How to Retrieve Virtual Infrastructure Logs from VMware vCenter and ESXi Servers

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.

How to DevOps with Azure?

In this article, I will not explain what is and what is not DevOps. I just want to describe how to implement a DevOps Project in your Azure subscription through the new service called “DevOps Projects”. This new service has been released in November 2017. The “DevOps Projects” service allows you to deploy and monitor your application in Azure.

Visual Studio Team Services and Team Foundation Services are Microsoft’s DevOps solutions for Azure. I’m not a VS or TFS expert, but as you will see, implementing DevOps with Azure is very straightforward. Microsoft says that you can implement your project in less than 5 minutes! Let’s see if it’s true.

RAID Today

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You may have heard that RAID is no longer applicable for enterprise storage: that it’s time had passed.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.

Demystifying HTTPS

Security Report Summary A+

In my time in IT I’ve installed certificates quite a few times on various web servers and into various applications but it’s really only in the past two years that I’ve started looking into HTTPS and the myriad of options that come with certificates which are often hidden deep into config files but yet can make the difference between a site that can be rendered vulnerable via a HTTPS downgrade attack or one that is actually secure because today, installing a cert is simply the tip of the iceberg so I thought it might be handy to go through the options that need to be set in a web servers config file in order to get A+ on both the Qualys and securityheaders.io web servers.

This blog is going to be all about the secure certificate side of things, by setting these headers you reduce the chances of certain types of probes and attacks from being successful. The server itself and whatever applications you are running on it still need to be upgraded and configured to reduce the chances of someone gaining unauthorised access to your systems.

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
No ratings yet.

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.

CLI vs. GUI for VMware Admins

The term User Interface (UI) is used for specifying how a user interacts with a specific device, or software. CLI and GUI are two different types of possible user interfaces.

Let’s analyze those different approaches and the pro and cons of them, using the VMware vSphere environment as an example.

Simplify storage management with Microsoft Systems Center VMM (SCVMM) and SMI-S

Manage StarWind VSAN storage from SCVMM using SMI-S - new logical volume for our StarWind device

SMI-S or ‘Storage Management Initiative – Specification’ is a standard of a storage management (surprise!) which gives you a chance to administrate the storage layer using ‘Common Information Model’ and Web-Based Enterprise Management technologies and logic. The main point of SMI-S is to provide a single standard to manage various storage systems from different vendors pretty much in the same way. In this article (?) we will show you how to manage your storage using SCVMM 2016 (Server Center Virtual Machine Manager) through SMI-S, and how this whole thing works in general. We’ll use StarWind Virtual SAN as a reference distributed storage platform, but the primary scope of this document is to cover the subject in general, so any SMI-S compatible storage will work.

Creating ESXi VMs on the Windows based NFS share

Creating ESXi VMs on the Windows based NFS share

Many words were said about NFS (Network File System), but what exactly NFS can give us? In general, NFS used as the ISO library or just simple network file share with easy access from any Windows or Linux based machine. However, starts from NFS 3.0 protocol can give us the good performance and can be as the shared storage for ESXi or any Linux based Hypervisors. In this article, I will create the NFS share on the Windows Server 2016 and then mount NFS share on the ESXi 6.5 and will create the VM on it.

How to enable Active Directory Recycle Bin in Windows Server 2016

Before we dive into how to enable Active Directory Recycle Bin in Windows Server 2016, we will first explain what it is and when Microsoft introduced this feature.

Active Directory Recycle Bin simply allows you to restore deleted objects from Active Directory. It can be a user account, computer account or a whole Organizational Unit (OU). Who did not accidentally delete an AD object in his career?
