Educational Episodes: Hyperconverged Infrastructure (HCI)

Greetings, fellow sysadmins and everyone who is still wondering how to make their SQL server highly available! You’re just in time since I’ve prepared for you detailed guidelines with pictures and explanations on how to achieve this goal by using the SQL Server AlwaysOn approach! The great thing is that we are also going to configure and review the full-fledged system with the disaster recovery scenarios implemented. I’ve decided to break this topic into 3 parts. First, we will go through the process of configuring AlwaysOn Failover Cluster Instance (FCI), the next part of this series will cover the deployment of a DR site for our cluster using AlwaysOn Availability Groups, and finally, we will learn more about how to achieve the same using 3rd party software.

Creating automation and orchestration requires taking multiple data center components which all speak different languages and chaining them together through one consistent workflow. Now there are a lot of programming and scripting languages that we can use as our orchestration engine such as Java, JavaScript, Perl, etc. – but one of the most common choices within the last 5 years has been PowerShell.

Amazon Web Services (AWS) and VMware are completing one of the most relevant partnerships around cloud services: VMware will offer their Software Defined Datacenter (SDDC) capabilities within AWS. With this partnership, VMware finally replaces the already sold vCloud Air cloud services.

At Microsoft Build 2017, the Nested Virtualization support in Azure has been announced. Now you can enable nested virtualization using the Dv3 and Ev3 VM sizes – not a wide variety, but Microsoft is going to expand the support for more VM sizes in the upcoming months.

Before we have started our journey through the storage world, I would like to begin with a side note on what is hyperconverged infrastructure and which problems this cool word combination really solves. Folks who already took the grip on hyperconvergence can just skip the first paragraph where I’ll describe HCI components plus a backstory about this tech. Hyperconverged infrastructure (HCI) is a term coined by two great guys: Steve Chambers and Forrester Research (at least Wiki said so). They’ve created this word combination in order to describe a fully software-defined IT infrastructure that is capable of virtualizing all the components of conventional ‘hardware-defined’ systems.

When you implement a virtual infrastructure, you may want to convert your physical servers to virtual ones to improve your datacenter consolidation. In this topic, we will see how to convert a physical Linux server to a VMware VM. To make this conversion, I used VMware vCenter Converter Standalone. To host VMware vCenter Converter Standalone, you need a physical or virtual machine based on Windows Server. Usually, when I run this tool, I use a virtual machine. Then, I run the executable to process the product installation.

Probably most of the enterprise businesses have heard of Microsoft Exchange Server. It’s Microsoft platform delivering email, scheduling, and tools for custom collaboration and messaging service applications and is installed on Windows Server operating systems. Its main aim is not just to let workers inside an organization communicate but to collaborate. So, you can install Exchange Server 2016 on Windows Server 2016 using two ways: PowerShell Graphical User Interface (GUI) However, in this article, I’ll focus on installation with the help of GUI.

This is going to be the third article in the series of reviewing and understanding Azure Stack (previous articles: Azure Stack Release and Deployment Models). Now that we have a good grasp of the platform, how the Integrated Systems come into play and features available; I want to extend the topics to other two important matters for existing customers of Azure: How the support model will work with hardware and software in place from different vendors; and what’s the interconnection with the already existing Azure Pack solution.

As all of you know, VMware Labs posts handful utilities for VMware administrators to make the management of vSphere virtualization infrastructure easier. Those tools are being developed by VMware Engineers, Community, and Open Source. Today I would like to emphasize some of the latest tools available to download and implement.
