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

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.

StarWind Maintenance Mode Overview

Howdy, folks! I would like to start my tale with a little backstory regarding usefulness which the “maintenance mode” brings to us. And in order to do that, I’ll start from the times when updates have led to the downtime for production. That’s not a secret for anyone that any production environment sometimes needs to be maintained. It could either be a software update or a hardware reconfiguration. To do this, the administrator should stop the production server for a certain period of time, and this may affect the reliability of the production environment. For example, the fault tolerance level can be decreased, as well as the performance. This is especially critical for small infrastructures which consist of 2 nodes.

StarWind VVols for VMware vSphere Environment

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.
