The following table describes some of the major changes in File and Storage Services functionality that are available in Windows Server For more information about what else is new in File and Storage Services and related technologies, see the following topics. By using the Data Deduplication role service to reduce the number of duplicate blocks of data in storage, you can store much more data in a given amount of storage capacity than was possible in previous releases that used Single Instance Storage SIS or NTFS file system compression.
General purpose file servers can typically reduce storage capacity utilization by a ratio for example, files that previously used 1 TB would use GB after data deduplication. Servers that host virtualization data such as VHD files often reduce storage capacity utilization by a ratio, which reduces 1 TB of data to 50 GB.
Data deduplication is highly scalable, resource efficient, and nonintrusive. It can run on dozens of large volumes of primary data simultaneously without affecting other workloads on the server. Low impact on the server workloads is maintained by throttling the CPU and memory resources that are consumed.
By using data deduplication jobs, you can schedule when data deduplication should run, specify the resources to duplicate, and tune file selection. Data integrity and recoverability are maximized through checksum and other algorithms by using selective redundancy. When combined with BranchCache, the same optimization techniques are applied to data that is transferred over the WAN to a branch office. This results in faster file download times and reduced bandwidth consumption. Data deduplication uses variable-size chunking and compression, which together deliver storage optimization ratios of for general file servers and up to for virtualization data.
Windows Server includes Data Deduplication as a role service that you can install and manage by using Server Manager or Windows PowerShell cmdlets.
The default settings can quickly reduce the amount of storage capacity that is used by your data. You can fine-tune the settings to see more gains or use Windows PowerShell cmdlets to create scripts that will trigger storage optimization when and where you want it. For more detailed information, see Data Deduplication. When combined with other continuously available technologies in Windows Server , iSCSI Target Server provides continuously available storage that was previously available only on expensive, high-end storage area network SAN devices.
Network or diskless boot By using boot-capable network adapters or a software loader, you can deploy hundreds of diskless servers. This is ideal for large deployments of identical operating system images, such as a server farm that is running Hyper-V or high-performance computing HPC clusters.
Server application storage Some applications for example, Hyper-V and Exchange Server require block storage, which is raw storage that appears to applications as an unformatted disk, which is ready for direct management by the application.
Because the storage is remotely accessible, iSCSI Target Server can also consolidate block storage for central or branch office locations. This is useful for testing applications prior to deployment on a SAN storage device.
Windows Server also includes changes to the clustering resource model that improve scalability so that more initiators can connect to the target servers. Storage Spaces provides resilient storage virtualization capabilities for business-critical virtual or physical deployments, including deployments on scalable multi-node servers.
After you group physical disks into storage pools, you can create virtual disks from the available capacity without individually managing each physical disk. This aggregation of disks enables you to create high performance, resilient, and cost-effective storage solutions. Storage Spaces reduces administration costs by decreasing the time administrators spend provisioning storage. They also simplify administration tasks, enabling administrators who are not storage professionals to set up and manage resilient and high availability storage.
Storage Spaces also saves hardware costs by using industry-standard disks for resilient storage with high availability. With storage pools, instead of managing each disk individually, you add physical disks to one or more pools and then create virtual disks from the available capacity.
You then create volumes on the virtual disks, as if they were physical disks. For more information, see Storage Spaces and Storage Management. The File and Storage Services role in Server Manager enables you to remotely manage multiple file servers from a single window in Windows Server R2 or Windows Server , including role services and storage. You can use the Servers page to perform such tasks as restarting servers and launching administrative tools.
Storage Pools Manage storage pools, including the physical disks that make up the pools and virtual disks that are created from available capacity in the pools. Volumes Manage volumes, including scanning for file system errors, extending volumes, and configuring Data Deduplication. Managing multiple file servers and file server technologies from a single Server Manager window enables administrators to work more efficiently and get a better overall view of the servers they manage, so managing multiple servers becomes as easy as managing one.
Prior to Windows Server , managing multiple file servers meant using Remote Desktop to connect to each server, or opening multiple instances of the administration console one per server. Hope this can be helpful. Thanks for the reply. The DFS share is used to distribute file and folders onto different folder target on different servers. For example:. DFS namespace share:. Besides, the performance will not be degraded in the case that we use DFS.

Although sometimes ya gotta jump through hoops to get there. Brand Representative for Lepide. Furthermore, you may also get help from Current Permission Analysis solution that helps you to compare the applied NTFS with the Share Permissions to analyze the currently effective permission on a selected file or folder.
The machine is a VM, and a pretty big file server - our organization is a 24hr shop but i can get it on the schedule for some downtime Not sure a chkdsk will work though The goal is to delete the folder and files contained within so any sort of destructive measures are absolutely acceptable options.
I get that Deny take precedence, but I'm struggling with the understanding of when "Domain Users" is set to Deny, the local administrator, local users, or non "Domain Users" are still unable to access Also, the files, while they are a subfolder of a shared folder, do not have any explicit shares - just inherited ones All my attempts to access the folder have been from local to the VM and most work was done under the local administrator or a domain admin account that had "Domain Users" removed.
Brand Representative for Netwrix. Soooooo thank you everyone for the suggestions but i found the problem. Even though i had bounced the server and kicked everyone out of the folders killed any active sessions - my boss decided he was going to try and help with the solve on this.
Since he had the folder locked, my initial attempt to delete the folder went into a kind of pending state. It wasn't until i stoped the services for the file server roles and kicked out my boss's account from RDP that i was able to try again. I am not going to mark this as the answer since the posts above would be so much more helpful for someone stopping by for a quick bit of help.
