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.

High Availability and Disaster Recovery with SQL Server AlwaysOn: FCI quick walk through
Posted by Bogdan Savchenko on September 19, 2017
5/5 (5)

Introduction

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.

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.

Free SMB3 Failover File Server on Microsoft Hyper-V Server 2016
Posted by Ivan Ischenko on August 3, 2017
4.67/5 (3)

In the previous article, we have created a free SMB3 file server. I decided to proceed with the testing of Microsoft Server Hyper-V 2016 free version possibilities. In this post, I will try to create Highly Available devices with StarWind Virtual SAN and then create a Microsoft Failover Cluster to make a Highly Available File Server.

We are using 2 servers with Microsoft Hyper-V 2016 added into a domain (Hyper-V-1; Hyper-V-2). Client node with Windows Server 2016 (2016-client-test).

StarWind VVols for VMware vSphere Environment
Posted by Dmytro Malynka on June 16, 2017
No ratings yet.

Introduction

VMDK file to LUN storage architecture has been the most usable scenario for years until VMware released Virtual Volumes in vSphere 6.0. In the case of an array with block access, own VMware file system – VMFS  – was used -, and NFS was used for file storage. The array capacity was divided into LUNs or NFS-shares and presented ESXi hosts in the datastore form. Frequently, datastore is a large capacity storage housing numerous VMs. In fact, allocating a separate datastore for each VM is quite inconvenient and time-consuming in terms of administration.

With this approach, the VM storage maintenance operations are at the datastore level, and not at the Virtual Machine level. The operations like snapshots, replication, deduplication, encryption, etc. are performed at the storage level, thus being implemented faster with no use of compute and networking resources. The traditional VM storage technology described in vSphere is still supported. At once, Virtual Volumes (VVols) is an object containing VM files virtual disks and their derivatives.

This handy and at the same time advanced technology was integrated with StarWind Products, that I am about to implement.

Design a ROBO infrastructure. Part 4: HCI solutions
Posted by Andrea Mauro on June 7, 2017
5/5 (1)

2-nodes hyperconverged solution

As written in the previous post, for ROBO scenario the most interesting HCI (Hyper-Converged Infrastructure) configuration is a two nodes configuration, considering that two nodes could be enough to run dozen VMs (or also more).

For this reason, not all hyperconverged solutions could be suitable for this case (for example Nutanix or Simplivity need at least 3 nodes). And is not simple scale down an enterprise solution to a small size, due to the architecture constraints.

Actually, there are some interesting products specific for HCI in ROBO scenario:

  • VMware Virtual SAN in a 2 nodes clusters
  • StarWind Virtual Storage Appliance
  • StorMagic SvSAN

Introduction

This article describes the new StarWind Virtual Storage Appliance, which was released on 26th of April. StarWind has always been a Windows native solution. However, due to market trends and the huge interest of our customers, we have decided to work in Linux direction. The main goal of the article is to show what StarWind VSA can do for clients and how you can work with it.

The Virtualization Review Editor’s Choice is a selection of the most outstanding virtualization products of 2016. It is based on the opinions and overlooks by the trusted experts in the fields of virtualization and cloud computing. This is not the “best of the best rating”. No criteria were applied to make the list. This is just the collection of individual choices of writers, who deal with the industry daily, so they have pointed out virtualization solutions they found especially interesting and useful.

VMworld Europe 2016 main announcements – all you need to know about new versions of VMware products in just one article
Posted by Alex Samoylenko on November 1, 2016
4.5/5 (4)

Just recently one of the main virtualization conferences VMworld Europe 2016 has finished. Traditionally, it has been held a while after the main VMworld in the USA. While in the USA VMware was speaking about the new technologies and the future of datacenters, in Europe much more attention was paid to the new features of updated VMware products. The main of them is, of course, VMware vSphere 6.5 server virtualization platform. We’ll start our overview with it.

As you know, the main virtualization conference VMworld 2016 arranged by VMware is now being held in Las Vegas. On the first day of the conference several interesting announcements were made. For example, VMware Cloud Foundation, which soon will be available on the IBM platform and later with other vendors, as well, was presented. It allows to get a ready-made infrastructure at customer’s site with both necessary software and hardware components and ready, configured and integrated control and automation tools like NSX, Virtual SAN and vRealize:
