Educational Episodes: Hyperconverged Infrastructure (HCI)

Does low latency, high throughput & CPU offloading require RDMA? What? Blasphemy, how dare we even question this? In my defense, I’m not questioning anything. I am merely being curious. I’m the inquisitive kind. The need for RDMA is the premise that we have been working with ever since RDMA became available outside of HPC InfiniBand fabrics. For us working in the Windows ecosystem this was with SMB Direct. Windows Server 2012 was the OS version that introduced us to SMB Direct, which leverages RDMA.

In this article, I discuss what VSAN from StarWind for vSphere is and how to set it up on the hardware RAID. StarWind VSAN for vSphere is a Software-Defined Storage solution that is designed specifically for vSphere environments. It comes as a preconfigured VM template, so just a couple of quick steps are needed to start running your vSphere environment on StarWind VSAN: download the solution, deploy it, and “play”. Here, I want to share some tips and tricks on working with VSAN for vSphere.

This article describes StarWind Storage Gateway for Backblaze as a solution to make local backup applications operate seamlessly with a cloud object storage.

One new announced feature in Windows Server 2019 is Storage Migration Service (SMS). SMS enables to ease drastically the migration from a file server to another. Moreover, SMS is fully manageable from Windows Admin Center as Microsoft has released an extension for this feature.

In Windows 10 Fall Creator Update, Microsoft introduced a new feature called the “Hyper-V Quick Create Wizard” which is very useful because you can create a Virtual Machine with the default settings and save time. Using this feature, you can create a VM with a single ISO file located on your system, or you can create a VM from the Online Gallery. By default, Quick Create will list a Windows 10 Developer Environment but you can easily add your own Virtual Machine Images from your local/online repository. In this article, I will describe how to use this feature and how to add a custom VM Image into your own Gallery.

Microsoft released a few weeks ago a new feature, to backup your SQL Server databases, directly from Azure Backup.  This new functionality is very interesting and is working smoothly for a preview. Adding of other databases types like Oracle, MySQL, PostGre, etc. could be very interesting.

This blog article discusses Access Rights feature and its implementation in VSAN from StarWind environment. Access Rights allows you to segregate the storage between multiple clusters or hypervisors. You can configure the feature with StarWind Management Console, and, in this article, I’ll teach you how that can be done.

Windows Server 2019 should be available in barely two months. So, first migration will start shortly after. From experience, I know that the first feature customers ask for migrating is Active Directory. Therefore, I wanted to try In-Place Upgrade, which has been improved in Windows Server 2019. To try this feature, I upgraded a forest that is handled by two domain controllers running on Windows Server 2016. It was not a “click and fun” process, but Microsoft has really improved In-Place Upgrade. Let’s take a look at how to migrate Windows Server 2016 DC to 2019.
