Microsoft Storage Spaces Direct is a new storage feature introduced in Windows Server 2016 Datacenter that significantly extends the software-defined storage stack in Windows Server product family and allows users to build highly-available storage systems using directly attached drives.

Storage Spaces Direct or S2D helps to simplify the deployment and management of software-defined storage systems as well as to open the use of more classes of disk devices like SATA and NVMe drives. Previously it was not possible to use these types of storage with clustered Storage Spaces with shared disks.

Storage Spaces Direct can use drives that are locally attached to nodes in a cluster or disks that are attached to nodes using enclosure. It aggregates all the disks into a single Storage Pool and enables the creation of virtual disks on top.

Why you should learn about SMB Direct, RDMA & lossless Ethernet for both networking & storage solutions

Server, Hypervisor, Storage

Too many people still perceive Windows Sever as “just” an operating system (OS). It’s so much more. It’s an OS, a hypervisor, a storage platform with a highly capable networking stack. Both virtualization and cloud computing are driving convergence of all the above these roles forward fast, with intent and purpose. We’ll position the technologies & designs that convergence requires and look at the implications of these for a better overall understanding of this trend.

Storage Spaces Direct: Overview

This is a short summary on Storage Spaces Direct – the first true software-defined storage from Microsoft, its history and peculiarities. Software-defined storage is a concept, which involves storing data without dedicated hardware. This is an introduction to a series of posts dedicated to theoretical and practical research of S2D. The post is not a full description of the Storage Spaces Direct technology, more info is available on Microsoft resources. Our focus here is the actual problem that S2D solved for virtualization world, being truly independent from underlying hardware, as SDS should. Its predecessor, Clustered Storage Spaces, had a very serious hardware lock-in with its requirements for SAS fabrics, SAS switches and SAS JBODS. Thus, Storage Spaces Direct is an interesting technology to research.
