In our support work very often we face different environments. They can range from three VMs to a hundred of those, with the number of nodes from two to ten.

Today, I will tell you about the main features of Failover Cluster 2016, which are applicable to any environment.

Combining Virtual SAN (vSAN) with Microsoft Storage Spaces for greater Performance and better Resiliency

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.

Introduction

Plenty of articles have been released about Storage Spaces and everything around this topic. However, I would like to absorb all actual information and lead you through the journey of configuring Storage Spaces on a Standalone host.

The main goal of the article is to show a Multi-Resilient Volume configuration process.

How it works

In order to use Storage Spaces, we need to have faster (NVMe, SSD) and slower (HDD) devices.

So, we have a set of NVMe devices along with SAS HDD or SATA HDD, and we should create performance and capacity tier respectively.

NVMe tier is used for caching. When hot blocks are written to the storage array, they are written to the caching tier first (SSD’s or NVMe):
