Improving your Azure Experience: How to Create and Configure ExpressRoute Circuits
Posted by Augusto Alvarez on December 14, 2017

One of the main objectives for an organization moving to a public cloud, in any type of shape or form, is regarding the overall performance experience: It cannot be a downgraded version of what they have with their on-premises services. Microsoft is well aware of that, therefore created some time back the possibility to use private connections from your datacenter to MS Azure’s datacenters in order to guarantee this performance.

Combining Virtual SAN (vSAN) with Microsoft Storage Spaces for greater Performance and better Resiliency
Posted by Vitalii Feshchenko on December 13, 2017
5/5 (1)

Introduction

Previously, we went through the Storage Spaces configuration journey.

The latest step was the creation of the storage pool and the virtual disk.

Today I would like to proceed from that point on and create Highly Available (HA) devices with StarWind Virtual SAN on Storage Spaces as an underlying storage. The main goal of this post is to run the performance tests of StarWind Highly Available (HA) devices located on Storage Spaces created in different ways (Simple and Mirror). StarWind HA devices will be mirrored between two hosts via a 40Gbps synchronization channel.

Microsoft has introduced Azure Cloud Shell, a new way of managing resources from the Azure Portal. Within a browser, you can use Bash to troubleshoot and automate your most common management tasks. Support for Windows PowerShell is expected soon. Azure Cloud Shell will help you to store your favorite scripts in the Cloud.

Deploying Microsoft LAPS
Posted by Gary Williams on December 7, 2017
5/5 (3)

As a summary, LAPS is the Local Administration Password solution from Microsoft. This software changes the local administrator password on a selection of machines on a schedule and stores that password in plain text in Active Directory.

The first time I came across LAPS was when I hear about project Honolulu and I’ll admit that I hadn’t heard about it before which is something of a shame because LAPS is one of those very handy little add-ins that Microsoft should be offering as part of the core AD experience.

For those who haven’t come across LAPS before, LAPS is a handy tool for scenarios where you need to change or set the local admin password to something random because you need to give out that password.

High-performing and highly available Scale-Out File Server with SMB3
Posted by Ivan Talaichuk on December 6, 2017
5/5 (2)

There’s, probably, no IT administrator who hasn’t heard of SMB3 (Server Message Block). is an application-layer network protocol, developed by Microsoft mostly to provide shared access to the files, and allowing communication between nodes. SMB has been designed as a tool for the creation of a DOS-based network file system, but Microsoft took the initiative and renamed SMB into CIFS later on (Common Internet File System) and continued further developing it. The second version – SMB 2.0, has been introduced in Windows Vista with a wide range of new features, thus it became clear that Microsoft was working hard to improve this protocol.

Now, to SMB3. It’s an improved version of the previous Server Message Block protocol that Microsoft introduced as one of the key features in Windows Server 2012 operating system. SMB3 comes with a significant number of new capabilities like SMB Transparent Failover, SMB Encryption, VSS for SMB file shares, SMB Direct (SMB over RDMA) and SMB Multichannel. SMB Multichannel allows file servers to use multiple network connections simultaneously, therefore increasing performance and adding one more level of Fault Tolerance within the networking layer.

Using a VEEAM off-host backup proxy server for backing up Windows Server 2016 Hyper-V Hosts
Posted by Didier Van Hoye on December 5, 2017
5/5 (1)

Introduction

Many years ago, I wrote a white paper on how to configure a VEEAM Off-host backup proxy server for backing up a Windows Server 2012 R2 Hyper-V cluster that uses a hardware VSS provider with VEEAM Backup & Replication 7.0.  It has aged well and you can still use it as a guide to set it all up. But in this article, I revisit the use of a hardware VSS provider dedicated specifically to some changes in Windows Server 2016 and its use by Veeam Backup & Replication v9.5 or later. The information here is valid for any good hardware VSS provider like the one StarWind Virtual SAN provides (see Do I need StarWind Hardware VSS provider?)

Network File System: access your files remotely as easily as if they were local
Posted by Alex Khorolets on November 30, 2017
5/5 (1)

Why do I need to use complicated ways to access my files that are located on company’s server or in my homelab, for example? I want to ask the same question in order to make remote files available for my local applications without any extra actions. The answer, as well as the solution to the problems listed above, lies in the next four words – Network File System protocol.

I’d like to start with the general description of the NFS technology and some background about its purpose, and how it was created. The story goes back to middle 80’s when, alongside with the Van Halen’s new “1984” album, the company named Sun Microsystems created a Network File System protocol. It allowed users to access some files from the servers over a network, just like if these files were located on users’ machines.

Since that time, there were several versions of the NFS protocol released. Originally, the protocol was operating over UDP till NFSv3 update, in which TCP was added as a transport service. That allowed transferring blocks of a larger size which was limited by UDP before. The latest versions of the NFS protocol, including v4, v4.1, and v4.2, were developed by another company named Internet Engineering Task Force (IETF). They include performance increase, multiple security updates, and scalability.

Here is the second article of 2 for the Azure Site Recovery implementation with ARM:

  1. Preparation of the environment (Part 1)
  2. Start the replication and Failover/Failback

Replicate your first VMs

Now that the Azure infrastructure is ready, we will go to step 2 to replicate VMs/Applications. Choose from where you want to replicate VMs (On-Prem for me) and to which the Hyper-V site that you created in the first article.

[Azure] Azure Site Recovery with ARM – Part 1

Today we will see how to implement a DRP solution, with Azure Site Recovery. I’ll deploy this solution, based on the ARM. ASR can be used to migrate your VMs to Azure, from VMWare to Azure, etc.

In my DRP plan, the service that I defined as critical for my business is a website. I’ll replicate this VM on Azure, with ASR. You can do the same work with a multi-tier application.

In my architecture, I have a VPN S2S to Azure. Attached to this network who is connected to the VPN, I have a second domain controller, who is acting as DNS.

Deploying SQL Server 2016 Basic Availability Groups Without Active Directory. Part 2: Configuring SQL Server
Posted by Edwin M Sarmiento on November 23, 2017
No ratings yet.

In the previous blog post, I’ve walked you thru the process of creating the Windows Server 2016 Failover Cluster  (WSFC) that is not joined to an Active Directory Domain. It is very important that you get the underlying WSFC properly configured and stabilized before you even attempt to create the SQL Server 2016 Always On Basic Availability Group. The availability and reliability of your SQL Server 2016 Always On Basic Availability Group depends so much on the WSFC.

If you have previously configured Always On Availability Groups, you will notice that most of the steps provided are similar to configuring it with Active Directory. But because there is no centralized directory service for managing accounts, you will need to rely on certificates for authenticating communication between replicas. You need to use T-SQL to accomplish those tasks.
