Storage Spaces Direct: Enabling S2D work with unsupported device types (BusType = NVMe, RAID, Fibre Channel)
Posted by Taras Shved on February 10, 2017

Introduction

Microsoft Storage Spaces Direct is a new storage feature introduced in Windows Server 2016 Datacenter, which significantly extends the Software-Defined Storage stack in Windows Server product family and allows users building highly available storage systems using directly attached drives.

Storage Spaces Direct, or S2D, simplifies the deployment and management of Software-Defined Storage systems and allows using more disk devices classes 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 Server 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 the 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.

How to Deploy and Manage Storage Spaces Direct Cluster using SCVMM 2016?

Introduction

With the release of Windows Server 2016, Microsoft is introducing Storage Spaces Direct (S2D), which enables building highly available Software-Defined Storage systems with local attached storage. This storage can be leveraged by VMs running on the same cluster (in hyper-converged mode) or the storage can be presented as a File Share (in disaggregated mode). The hyper-converged deployment scenario has the Hyper-V (compute) and Storage Spaces Direct (storage) components on the same cluster. Virtual machine’s files are stored on local CSVs. Once Storage Spaces Direct is configured and the CSV volumes are available, configuring and provisioning Hyper-V is the same process and uses the same tools that you would use with any other Hyper-V deployment on a failover cluster.

Why moving from Windows Server 2012 R2 to 2016 for Hyper-V
Posted by Romain Serre on August 16, 2016
5/5 (9)

Windows Server 2016 will be released the next month said Microsoft the last month. Windows Server 2016 brings a lot of new features compared to the last Windows Server version for Hyper-V, networking and storage. In this topic I will try to convince you to move from prior Windows Server edition to Windows Server 2016 with eight reasons.

Microsoft published details of how Windows Server 2016 will be released and maintained, which includes a “Windows as a service” model of frequent operating system updates.

Windows Server 2016 will be launched at the Ignite conference (September 26 to 30 in Atlanta, Georgia); there will be three editions: Datacenter, Standard and Essentials.

Windows 2016 Makes a 100% In Box High Performance VDI Solution a Realistic Option
Posted by Didier Van Hoye on June 27, 2016
5/5 (5)

1. Introduction

With Windows Server 2016 we have gained some very welcome capabilities to do cost effective VDI deployments using all in box technologies. The main areas of improvement are in storage, RemoteFX and with Discrete Device Assignment for hardware pass-through to the VM. Let’s take a look at what’s possible now and think out loud on what solutions are possible as well as their benefits and drawbacks.

Software-Defined Storage: StarWind Virtual SAN vs Microsoft Storage Spaces Direct vs VMware Virtual SAN
Posted by Anton Kolomyeytsev on June 16, 2016
4.75/5 (4)

This is a comprehensive comparison of the leading products of the Software-Defined Storage market, featuring Microsoft Storage Spaces Direct, VMware Virtual SAN and StarWind Virtual SAN. It provides numerous use cases, based on different deployment scales and architectures, because the mentioned products all have different aims. As the market is already large enough, the vendors used to dwell its different parts, but lately they entered a full-scale competition, adapting their products to meet general demand. This post is an analysis of how Microsoft, VMware and StarWind fare in in the Software-Defined Storage market right now. The approach is practical and all the statements are based on the experience of virtualization administrators and engineers from all over the world.

Let’s Get Real About Data Protection and Disaster Recovery
Posted by Jon Toigo on April 7, 2016
4.75/5 (4)

Personally, I am getting rather tired of the dismissive tone adopted by virtualization and cloud vendors when you raise the issue of disaster recovery.  We previously discussed the limited scope of virtual systems clustering and failover:  active-passive and active-active server clusters with data mirroring is generally inadequate for recovery from interruption events that have a footprint larger than a given equipment rack or subnetwork.  Extending mirroring and cluster failover over distances greater than 80 kilometers is a dicey strategy, especially given the impact of latency and jitter on data transport over WAN links, which can create data deltas that can prevent successful application or database recovery altogether.

Storage Spaces Direct: 4-node “Shared Nothing” Scale-Out File Server
Posted by Anton Kolomyeytsev on January 22, 2016
5/5 (2)

This is a research dedicated to practical implementation of Microsoft Storage Spaces Direct. It is a part of a series of posts about S2D and features a detailed comprehensive instruction on building a fault-tolerant 4-node setup. Storage Spaces Direct is the next step of Storage Spaces, meaning it is an extension of the current SDS for Windows Server. Storage Spaces Direct utilizes SMB3 for all intra-node interaction, including the latest SMB Direct and SMB Multichannel. The testing of S2D is hot right now, so StarWind is doing its part as well. This setup is meant to withstand node failures and the post reveals how exactly it performs in this respect.

Storage Spaces Direct: Overview
Posted by Anton Kolomyeytsev on November 20, 2015
5/5 (1)

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.
