Virtual workload migration with VMware
Posted by Askar Kopbayev on
March 27, 2017
It is quite surprising how many companies migrate virtual workload nowadays. There could be different reasons – expiring contract with the service provider, move to the new office, consolidation of resources to minimize Capex and Opex, but in every case, companies need efficient and flexible V2V migration solution.
Very often people think of migration in terms of moving data from one place to another. However, migration is much more than that. For instance, you would probably want VMs to keep the same IP addresses after the migration. Which means you need to consider stretching VLANs between the source and target locations in case you cannot migrate all VMs in particular subnet in one go. You must plan a network cutover too.
Data Management Moves to the Fore. Introduction

To the extent that the trade press covers, meaningfully, the issues around digital information processing and technology, it tends to focus rather narrowly on the latter: infrastructure. The latest hardware innovation — the fastest processor, the slickest server, the most robust hyper-converged infrastructure appliance — tends to be the shiny new thing, hogging the coverage.
Occasionally, software gets a shot at the headlines: hypervisors, containers, object storage systems, even APIs get their 10 minutes of fame from time to time. But, even in these days of virtual servers and software-defined networks and storage, software is less entertaining than hardware and tends to get less coverage than tin and silicon.
Hyper-V Networking 101. Part 1: NICs and Switches

March 22, 2017
There are lots of posts regarding Hyper-V networking. But there doesn’t seem to be a single compiled and up to date guide covering fundamentals and some advanced topics alike. This article aims to fill that gap, without a wall of text but a few easy to understand diagrams, tables, and PowerShell snippets. We will take a look at Hyper-V’s basic networking concept, NIC teaming (Network Interface Card) and different approaches to let VMs (Virtual Machines) talk to specific VLANs or even VLAN trunks.
The first article in the Hyper-V Networking 101 series will cover everything you need to know about virtual switches and NICs. The last post is planned as a real-world example: A way to implement a secure Wi-Fi (and/or wired) guest network on top of a virtual firewall.

Veeam Backup Entreprise Manager is an optional component that enables to consolidate several Veeam Backup & Replication server through a single pane of glass. Veeam Backup Enterprise Manager provides a web-based interface to centrally control and manage all jobs. You can edit job, monitor them and have a consolidated view of the reporting of all Veeam Backup & Replication server. In this topic, we’ll see how to configure Veeam Backup Enterprise Manager.
[Azure] Continuous Integration / Continuous Deployment with Docker (ACS and ACR), Visual Studio Code, Visual Studio Team Services and GitHub

A major force of infrastructure today is the possibility to use CI/CD. Understand, Continuous Integration and Continuous Deployment.
To resume, these technologies, give the possibility to your developers to create/modify their codes, send them to GitHub for example, build it with Visual Studio Team Services (VSTS), save it on you registry (Azure Container Registry for me), manage the versioning, always with VSTS, send it to your Docker Swarm cluster as container et to finish, access it through a simple web interface.

Thanks to the previous part, we have SQL Server 2016 installed and configured. Before running the SCCM installation process, let’s remember the architecture we are implementing.
Eliminating Blue Screen or Errors during failover

The reason for writing this post was a recent case from one of our customers, who ran into an issue when their SAN switch failed. The problem was that their VMs were generating an enormous amount of errors that were caused by the switching of active paths at the time of failover.

Installing SharePoint 2016

Recently there was an article on StarWind Blog dedicated to Exchange 2016 installation written by Nicolas Prigent, so I decided that some folks might want to get something similar for SharePoint 2016, so here you are. Disclaimer: I did not touch on scripting SharePoint installation with PowerShell or any other advanced stuff, but I promise that you’ll find some interesting details beyond of “how do I click my way through setup wizard” information.
Microsoft’s SharePoint evolved quite dramatically in three previous major releases (2007, 2010, 2013) and now we have yet another version – SharePoint 2016. As usual, in this release, you can find additional functionality and loads of things to learn. But I think what you may be interested in it is just how to do a quick install to play with the latest version of SharePoint and test if it works well for your scenarios whatever they are. For example, in my case, I am going to test different scenarios of integration between K2 blackpearl and SharePoint 2016 among many other things. Disclaimer: if you in a mood to read somewhat dry and lengthy official installation guide – it exists and should be perused before doing production installation, but as the usual official documentation does not go as a pleasant easy read for the majority of people.
A little about Disk write cache on Windows VM

There are lots of great materials on optimization of virtualized environments that I think many of you will enjoy reading about. Such topics are all over the IT community and they cover a wide range of the technical questions. This article will focus on the matter which is not quite clear yet, especially when it comes from theory to practice. It’s about Windows Disk write cache feature and its implications for data consistency and performance of the virtual hard drives.
