Storage spaces come with features that provide resiliency, scalability, high availability and ease of administrative operations. Storage Spaces gives administrators the option to deploy a resilient and highly available storage system utilizing cost-efficient hardware – commodity SAS JBOD (Just a Bunch Of Disks) enclosures, and commodity SAS adapters.
Storage pool: Provides a means to administer, aggregate, and isolate a set of physical disks. Storage space: Provides an abstraction for resiliency, provisioned capacity, and performance level. Storage Spaces provide resilient storage in the form of mirror spaces with dirty region tracking, and parity spaces with integrated journaling. Windows’ Failover Clustering is a feature that enables multiple servers (known as cluster nodes) to be formed into a cluster which provides high availability for the underlying storage and supported workloads, such as File Server and Hyper-V.
Thin provision allows administrators to have straight-forward storage planning, focusing on the minimum number of physical drives to deploy and the near-term size of their datasets. Mirror Spaces: Stripes and mirrors data across a set of pool disks, supporting a two-way or three-way mirror, which are respectively resilient to single disk, or double disk failures. Parity Spaces: Stripes data across a set of pool disks, with a single disk write block used to store parity information, and is resilient to a single disk failure.
Suitable for large block append-style workloads, such as archiving, in non-clustered deployments. The mirror and parity resiliency delivered by Storage Spaces allows administrators to still have access to their data even after a drive failure has occurred. This allows enterprises to deploy industry-standard storage hardware and save costs, without any degradation in tolerance to drive failures and power loss events. Simple Spaces: Stripes data across a set of pool disks, and is not resilient to any disk failures.
Suitable for high performance workloads where resiliency is either not necessary, or is provided by the application. To ease the creation of pools and spaces, storage spaces allows the administrator to set default resiliency values, such as number of columns and stripe interleave, for individual storage pools. Journal: In the event of power loss and similar server fault events, the integrity of parity spaces is protected through journaling.
Storage Spaces in conjunction with Failover Clustering can deliver a resilient, highly available, and cost-efficient solution which can be scaled from simple deployments to the needs of a large datacenter.
Storage spaces with clustering and CSV while using commodity storage can allow admins to have a cost-effective, scalable, and manageable solution. Storage Spaces and Failover Clustering can scale along with business needs through the addition of multiple deployment elements of homogeneous or heterogeneous configurations, up to a total of 64 nodes, or 16 4-node deployment elements.
Consolidation of multiple workloads into a single server often results in multiple datasets sharing the same storage hardware. Thin provisioning affords administrators the opportunity to provision more capacity than initially available physical storage.
Storage Spaces allows administrators to create spaces which use fixed and thin provisioning in the same pool. In order to provide easy sharing of storage capacity, each thinly provisioned space only consumes the capacity it actually requires to host data. Storage Spaces provides on-demand provisioning with automated capacity reclamation, using the trim and unmap commands.
The pooling model used in Storage Spaces enables flexible and granular administrative control. Storage spaces significantly reduce the cost of available, reliable, and scalable storage because it does not require a storage network and external storage subsystem. It is easily scalable, highly resilient, highly available and easy for administrators to manage.
First you can use Windows Server together with Storage Spaces, which will offer you a really great enterprise and scalable storage solution for low cost.
Second you can use Windows Server to mask your existing Storage, by building a layer between the Hyper-V hosts and your storage. At the moment there are not a lot of vendors out there which offer SMB 3.0 in there storage solution. Basically what the Scale-Out File Server let you do it so cluster up to 10 file servers which all will share CSVs (Cluster Shared Volumes) like you know from Hyper-V hosts and present SMB shares which are created on the CSV volumes.
As already mentioned you can use your already existing storage appliance as storage for your Scale-Out File Server CSVs or you could use Windows Server Storage Spaces which allow you to build great storage solution for a lot less money. Microsoft first released there Software Defined Storage solution called Storage Spaces in Windows Server 2012 and this allows you basically to build your own storage solution based on a simple JBOD hardware solution. Continuous availability – Storage Pools and Disks can be clustered with the Microsoft Failover Cluster so if one server goes down the virtual disks and file shares are still available.
Flexible resiliency options – In Windows Server 2012 you could create a Mirror Spaces with a two-way or three-way mirror, a Parity Space with a single parity and a Simple Space with no data resiliency. Storage Tiering – Windows Server 2012 R2 allows you to use different kind of disks and automatically moves “hot-data” from SAS disks to fast SSD storage. Data Deduplication – Data Deduplication was already included in Windows Server 2012 but it is enhanced in Windows Server 2012 R2, and allows you to use it together with Cluster Shared Volumes (CSV) and supports VDI virtual machines. As mentioned both of this techologies do not require each other, but if you combine them you get a really great solution. To scale this even bigger you can go to way, you could setup a new Scale-Out File Server Cluster and create new file shares where virtual machines can be placed. With the 2012 R2 releases of Windows Server and System Center Microsoft made some great enhancements to Storage Spaces, Scale-Out File Server, SMB, Hyper-V and System Center.
Management – Management of Hyper-V and Scale-Out File Servers as well as Storage Spaces right in System Center 2012 R2 Virtual Machine Manager. Deployment – Deploy new Scale-Out File Server Clusters with and without Storage Spaces directly from System Center 2012 R2 Virtual Machine Manager via Bare-Metal Deployment. Rebalancing of Scale-Out File Server clients – SMB client connections are tracked per file share (instead of per server), and clients are then redirected to the cluster node with the best access to the volume used by the file share.
SMB bandwidth management – Enables you to configure SMB bandwidth limits to control different SMB traffic types.
Multiple SMB instances on a Scale-Out File Server – Provides an additional instance on each cluster node in Scale-Out File Servers specifically for CSV traffic.
I hope I could help with this blog post to understand a little bit more about the Scale-Out File Server and Storage Spaces, and how you can create a great storage solution for your cloud Environment. Btw the pictures and information are taken from people like Bryan Matthew (Microsoft), Jose Barreto (Microsoft) and Jeff Woolsey (Microsoft).

With ReFS, scrubber goes further by ensuring that if a corruption occurs to a subset of copies, it corrects the corruption from a good copy. Hence, parity spaces quickly recover from a power loss or similar server fault event by replaying the journal. The JBOD enclosures are connected to all of the servers in the deployment element with data access resiliency as noted in a prior section such that each server has redundant paths to all of the disks in each JBOD enclosure. In either case, running workloads that support high availability can quickly failover to another server in the event of a server failure or maintenance need. This allows administrators to add drives in advance of the pool’s capacity becoming fully consumed. Storage Spaces fully integrates with Active Directory and the Windows security model, providing a familiar model and tools for administration. Storage Spaces supports mixed deployments, so it is possible to utilize both SSD and HDD media types and control placement at storage space granularity. Most of the time you will have 2 controllers for fail-over and a little bit of manual load balancing where one LUN is offered by controller 1 and the other LUN is offered by controller 2. In Windows Server 2012 R2 a Hyper-V host can be connected to multiple SOFS node at the same time.
You can build your own storage based on Windows Server, which not only allows you to share storage via SMB 3,0 it also allows you to share storage via NFS or iSCSI. Or you could extend the existing cluster with more servers and more shared SAS disks chassis which don’t have to be connected to the existing servers. This makes troubleshooting easier and reduces the need to capture network traces or enable more detailed diagnostic event logging. This allows you to take advantage of key SMB features, such as SMB Direct and SMB Multichannel, by providing high speed migration with low CPU utilization.
A default instance can handle incoming traffic from SMB clients that are accessing regular file shares, while another instance only handles inter-node CSV traffic. These features help ensure that space is not wasted and data is stored in an optimized and effective method. But in my opinion you can get a huge benefit by using Windows Server in different scenarios. Together with SMB Transparent Failover the Hyper-V host does not really get any storage downtime if on of the SOFS nodes fails.
Which means that VM1 and VM2 running on the same Hyper-V hosts can be offered by two different SOFS nodes. The Virtual Disks, also called Storage Spaces, can have different resiliency levels like Simple, Mirror or Parity and you can also create multiple disks on one storage pool and even use thing provisioning. With SMB Multichannel you can use multiple NICs for example 10GbE, infiniband, or even faster network adapters. This is possible because of features like CSV Redirected mode hosts can access disks from other hosts even if they are not connected directly via SAS, instead the node is using the Ethernet connection between the hosts.

In case on of the SOFS nodes dies, the Hyper-V host fails over to the other SOFS node without any downtime for the Hyper-V Virtual Machines. True, this is not something totally different, this is something storage vendors do for a long time. There are two types of office arrangement under the stairs.View in galleryThe first one is facing the wall, positioned along the steps and the other one is positioned perpendicular. Basic idea to create interior design Tips To Create Classic Wall DesignNo all people like modern style, A there are still a lot people that like classic style. Sliding doors would be the best choice because it’s not going to take up a lot of space, but they can be expensive. This means that this space can be used to store something that has to be at any moment at hand. Depending on what type of situation you are facing and what decor or architecture that space under your stairs from the hallway can be used to expand your decor or as storage area. Storage is not the only option here; you can also use that area to extend your interior setting.
I see a nice couch or a big comfortable arm chair working just perfect in that spot, or simply use it to support your favorite decorations. If your answer is “yes” then you did o very good job maximizing your space, if the answer is “no” –why not?
I saw something like this in a tailoring workshop, where because of the tight space the owner mounted drawers under the access stairs where they kept both fabrics and threads.They had everything organized vertically with distinct drawers for different types of fabric as well for the various types of threads. The fact that the stairs are left opened you can use non-uniform deformations of the wood and other elements to achieve you desired storage units. That type of storage adds an enormous amount of texture in the room with steps and shelves as well as the items stored underneath.
This example does just that and transforms something common we already know in something else that can still serve as the thing that was designed for and some extra new features. Do not get me wrong on this, we are not reinventing the wheel here, we are just finding new ways and places for it.
