Windows Server 2016 Storage Space Direct Configuration

Windows Server 2016
Windows Server 2016 already RTM (Release to Manufacture) on October 12, 2016. One of the new feature on Windows Server 2016 is Storage space Direct. Storage Direct uses by industry-standart server with local-attached drive to create storage available, scalable with sof storage to reduces a lot of cost of SAN or NAS Storage. Windows Server 2016 with storage space direct have two architecture, it converged and hyper-converged. with feature like caching, storage tiers and erasure coding.

Windows Server 2016 Storage space direct have a minimum hardware requirements. For production server, microsoft recommend acquiring Windows Server 2016 of hardware/software. this is includes deployment tools and procedures.

Designed from Windows Server 2016 storage space direct is about fault tolerance and microsoft called 'resiliency' for customer data. RAID config there are a few ways storage space direct can do that. With Windows server 2016 storage space direct these config fall into two system : mirroring and parity.

Configuration options
1. Converged

Capacity and figure in discrete groups. The joined arrangement alternative, otherwise called 'disaggregated', layers a Scale-out File Server (SoFS) on Storage Spaces Direct to give organize appended capacity over SMB3 document offers. This takes into consideration scaling process/workload freely from the capacity bunch, fundamental for bigger scale arrangements, for example, Hyper-V IaaS (Infrastructure as a Service) for specialist co-ops and undertakings.

2. Hyper-Converged

One bunch for figure and capacity. The hyper-merged arrangement alternative runs Hyper-V virtual machines or SQL Server databases specifically on the servers giving the capacity, putting away their records on the neighborhood volumes. This dispenses with the need to design document server get to and consents, and decreases equipment costs for little to-medium business or remote office/branch office arrangements. See Hyper-joined arrangement utilizing Storage Spaces Direct.

Organizing Equipment. Storage rooms Direct uses SMB3, including SMB Coordinate and SMB Multichannel, over Ethernet to connect between servers. We emphatically prescribe 10+ GbE with remote-coordinate memory get to (RDMA), either iWARP or RoCE. 

Storage Server, From 2 to 16 servers with nearby connected SATA, SAS, or NVMe drives. Every server must have no less than 2 strong state drives, and no less than 4 extra drives. The SATA and SAS gadgets ought to be behind a host-transport connector (HBA) and SAS expander. We unequivocally prescribe the carefully built and widely approved stages from our accomplices (coming soon). 

Failover Grouping. The implicit grouping highlight of Windows Server is utilized to associate the servers. 

Software Storage Bus : The Software Storage Bus is new in Storage Spaces Direct in Windows Server 2016. It spans the cluster and establishes a software-defined storage fabric whereby all the servers can see all of each other’s local drives. You can reduces a lot of cost by buying a Fibre channel and SAS cabling.

Storage Bus Layer Cache : The Software Storage Bus dynamically binds the fastest drives present for example SSD to slower drives for example HDD SAS or SATA to provide server-side read/write caching that accelerates IO and boosts throughput your data traffict.

Storage Pool : consist of 1 untul n-drives that form the basis of Storage Spaces is called the storage pool in the one server. It is automatically created, and all eligible drives are automatically discovered and added to it. Microsoft give recommendation to you use one pool per cluster, with the default settings.

Storage Spaces : fault tolerance to virtual "disks" using mirroring, erasure coding, or both based function from Storage Spaces provides . You can think of it as distributed, software-defined RAID using the drives in the disk pool. In Windows Server 2016 Storage Spaces Direct, these virtual disks typically have resiliency to two simultaneous drive or server failures though chassis and rack fault tolerance is also available.

Resilient File System (ReFS) : ReFS is the premier filesystem purpose-built for virtualization in Windows Server. It includes dramatic accelerations for virtual machines disk .vhdx file operations such as creation, expansion, and checkpoint merging, and built-in checksums to detect and correct bit errors. It also introduces real-time tiers that rotate data between so-called “hot” and “cold” storage tiers in real-time based on usage.

Cluster Shared Volumes : The Cluster Shared Volumes file system unifies all the ReFS volumes into a single namespace accessible through any server into one cluster, so that to each server, every volume looks and acts like it’s mounted locally.

Scale-Out File Server : This final layer is necessary in converged deployments only on Windows Server. It provides remote file access using the SMB3 access protocol to clients, such as another cluster running Hyper-V in cluster, over the network, effectively turning Storage Spaces Direct into network-attached storage (NAS).
