The XenData Cloud File Gateway software is the foundation for our hybrid cloud solutions. It manages a single highly scalable file system across two storage tiers: on-premises RAID and Microsoft Azure blob storage. The storage system allows existing file-based applications to use cloud storage without the need for modification. Its tiering policies keep frequently accessed files on local storage, which minimizes cloud access costs and Internet bandwidth usage.

The system is optimized for video, image and other large files. This makes it ideal for a wide range of applications including creative media, video surveillance, medical imaging and many scientific and engineering uses.

The Cloud File Gateway software runs on a Windows server or client computer and the file system is presented as a logical drive letter, which can be accessed locally or as one or more Windows network shares. The gateway provides the following functionality:

Scalable to Petabytes

The content stored in the cloud is unlimited, easily scaling to multiple petabytes, and the data held on local disk can scale to 256 TB. A single gateway can store up to two billion files within the hybrid file system.

Tailored Local and Cloud Storage Policies

The XenData tiering policies determine which files are written to the cloud, local storage or both. The user can set policy rules for various file types and folders. Timed local disk retention rules may also be applied to files written to the cloud, determining how long files are held on local disk after written or last read.

Scheduling Optimizes Internet Bandwidth

Time windows are scheduled so applications can write to local disk while postponing a copy being made to Azure, allowing Internet bandwidth to be optimized when in high demand.

Partial File Restore (PFR) Support

Ideal for creative video applications, only a portion of a large file is required with PFR to create a video clip, avoiding the need to download the entire file.

Standard File Sharing and Security

Files may be accessed locally or shared via SMB or FTP. The tiered storage volume is fully compliant with the Microsoft security model based on Active Directory, allowing for easy introduction into an existing Windows domain or workgroup.

Cloud File Gateway Software

The Cloud File Gateway software can be installed on a Windows Server 2012 R2 server or Windows 10 computer with a local NTFS disk volume that becomes the on-premise storage.
