Educational Episodes: Hyperconverged Infrastructure (HCI)

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? Without this feature enabled, you had only a few choices. Either you could restore if you used a backup solution allowing you to restore individual AD objects (many virtualization backup vendors do that nowadays). Or you have had less chance and your AD server wasn’t configured to be backed up and you have to recreate the user and reinstall his profile on his computer.  

Companies often store critical client mailbox data on an Exchange server database. The Exchange database is a warehouse of critical mailbox information such as contacts, notes, calendar items and emails of thousands of users. One of the most serious issues companies can face is the corruption of the Microsoft Exchange 2013 database file leading to unavailability of important data for the client. The Microsoft Exchange 2013 database can become vulnerable to crashes due to unavoidable hardware issues, software malfunctions, system freezes, server or boot failures, accidental shutdowns or any unforeseen circumstances. Since the last thing a company wants is to endanger business goals such as data availability during disasters, the first step is to make efforts to recover the damaged file.

Before the time when SSDs took their irreplaceable place in the modern datacenter, there was a time of slow, unreliable, fragile, and vacuum filled spinning rust drives. A moment of change divided the community into two groups – the first with dreams of implementing SSDs in their environment, and the second, with SSDs already being part of their infrastructure. The idea of having your data stored on the associated tier has never been so intriguing. The possibility of granting your mission-critical VM the performance it deserves in the moment of need has never been more appropriate.

Well, hyperconvergence is certainly a good deal but there are certain factors to consider when choosing a hyper-converged vendor. Support is a number one thing you should be looking for. Basically, decent support increases chances that your production remains operational all the time or at least minimizes the downtimes. Unified management is the “core” of hyperconvergence, so make sure you won’t need any additional software for administrating your hyper-converged infrastructure. Finally, the price. Take your time and calculate if you’re not overpaying just for a vendor’s “logo”. So, there is a wide variety of hyper-converged appliances, but I hope these three simple factors will help you with choosing a vendor that will provide you with the one that will serve you faithfully.

Today I will deal with data deduplication analysis. Data deduplication is a technique that helps to avoid storing repeated identical data blocks. Basically, during the deduplication process, unique data blocks, or byte patterns, are identified and written to the storage array after being analyzed. While such analysis is a continuous process, other data blocks are processed and compared to the initially stored patterns. If a match is found, instead of storing a data block, the system stores a little reference to the original data block. In case of small environments, this is not crucial mostly, yet for those with dozens or hundreds of VMs, the same patterns can be met numerous times. Thus, due to the advanced algorithms used, data deduplication allows storing more information on the same physical storage volume compared to traditional data storage methods. This can be achieved in several ways, one of which is StarWind LSFS (Log Structured File System), which offers inline deduplication of data on LSFS-powered virtual storage devices.

So, we all know about Microsoft’s Storage Spaces Direct (S2D to put it simple) by now. It’s the feature introduced in Microsoft Server 2016 (Datacenter Edition) that pools together server’s storage allowing to build…that’s right: highly available and easily scalable software-defined storage systems. In this article, I’m gonna talk about not as much about its fault-tolerance characteristics themselves, but some hands-on experience, namely: how to replace a failed disk.

Veeam has released in December the update 3 of Veeam Backup & Replication which brings the central management of Veeam Agent for Windows / Linux. Thanks to this update you can now manage backup of physical machines or cloud instances from a single pane. In this topic, we’ll see how to manage a physical machine from the console of Veeam Backup & Replication.

If you have a single environment with only several iSCSI targets discovered from a couple of target portals, messing with automation may not be worth it. Yet, if you have multiple environments with a bunch of portals and targets that need to be discovered and connected, and all of them are more or less similar in terms of configuration, you might find your resort in automating the whole process. I hope to post some other automation things here, so tune in and check the StarWind blog from time to time.

Official Microsoft description: “Azure DevTest Lab is a service that helps developers and testers to quickly create environments in Azure while minimizing waste and controlling cost. You can test latest version of your application by quickly provisioning Windows and Linux environments using reusable templates and artifacts.” In other words, Azure DevTest Labs is a great service that will help you to implement DevOps in your organization. Azure DevTest Labs will allows you to easily deploy Virtual Machines in order to test your workload in Azure. Setting up a development and test environment can take lots of time for your Ops Team.
