With the release of FASP 3, Aspera is bringing to market a truly universal content transport platform supporting all data, infrastructure and storage types, regardless of location, with maximum speed and a comprehensive offering for all transport paradigms and deployment models.


FASP 3 products are intrinsically enabled for cloud object storage such as Amazon Web Services S3, IBM SoftLayer Swift, Microsoft Windows Azure BLOB and OpenStack Swift. They can deliver secure, line-speed transfers of big data regardless of storage type or location (block, object, on-premise, in the cloud, hybrid or embedded) and independent of network types or conditions.

This allows you to store large volumes of data anywhere, on premise or in the cloud, and move it at high speed between storage end-points. By hiding the underlying complexities of different storage types and vendors, FASP 3 technology enables infrastructure-agnostic workflows that maximize on-premise resources and leverage cloud infrastructure for seamless, on-demand scaling of storage and compute capacity.


When file sizes are small, the metadata can be as big as the files themselves. Transferring very large amounts of small files can be inefficient and time-consuming when the large quantity of metadata is sent through the transmission control path (i.e. not FASP) and file open and close rates can’t keep up with high-speed transmission rate.

a4 technology in FASP 3 addresses these challenges to send even the largest sets of unique individual files and directories at FASP speed:

  • Metadata is sent via the data transmission path (i.e. via FASP) instead of via transmission control path
  • The number of parallel I/O "worker" threads can be configured based on the native storage system characteristics (e.g. parallel file systems)
  • The size of the data chunks that are read from disk is configurable
  • Pipelined file I/O mechanism feeds incoming chunks through compression, encryption and transfer as they are coming in from disk


The latest generation of Aspera’s transfer rate control system further boosts Aspera's industry-leading performance by more precisely measuring and interpreting network conditions and optimizing transfer speeds and efficiency accordingly, in real-time. These changes deliver higher transfer speeds with more efficient bandwidth utilization, more robust performance on fast-changing network conditions, and improved fairness among multiple transfers sharing the network.


FAS{ 3 incorporates built-in support for the new high-speed Aspera fasp Proxy enabling passage of FASP transfer sessions across secure DMZs. FASP Proxy uses native Linux kernel-level packet forwarding to fully maintain FASP transfer speeds between a client and a server. The proxy uses DNAT to help you protect your internal network and enforces user authentication to help you control which internal users can initiate fasp transfers.


Aspera's new Node API provides a modern, full-featured, RESTful API for developers who want to interoperate with Aspera transfer servers. Using the Node API, 3rd-party programs can execute fast, synchronous operations on any Aspera Transfer Server using JSON-formatted HTTP requests/responses or XML-based messaging through a SOAP service interface.

Supported operations include:

  • Performing file system operations like browse, search, delete, rename, create folders and files, etc.
  • Acquiring information from the node needed to set up a transfer, including token, user, port, etc.
  • Query the status of a node (i.e. perform a ping).


A new configuration option preserves the timestamp of transferred files for workflows that require exact file replicas (e.g. Legal and eDiscovery)


Automatic, fast and lossless inline LZO compression option can help reduce data set transfer sizes for compressible file types, further boosting Aspera’s industry-leading transfer performance.


Using the new pvcl extensible transfer framework, Aspera Transfer Servers can now link fasp transfers to FTP transfers by establishing direct connections to FTP servers. This enables transfer workflows that take advantage of high-speed FASP transfers over the WAN and use FTP to move data to and from FTP end-points where the deployment of Aspera software is not an option (e.g. receiving content from outside providers and moving it to an internal FTP-based end-point).


The new file-pair list feature allows command line users to specify an unlimited number of source-destination file pairs to be transferred, the ability to uniquely rename each source item at the destination and to secure the session with the Aspera token authorization independent of number of items, enabling more precise control over how multiple files are copied (e.g. renaming files in the process, transferring files from one folder at the source into separate folders at the destination, etc.). 

“Aspera’s technology not only provides significantly faster transmission speeds, which reduce the margin for error but also includes comprehensive security and data verification schemes to ensure that the possibility of corruption is reduced significantly. Plus, adaptive bandwidth control allows concurrent transfers to run with high efficiency, enabling us to meet strict deadlines.”Jonathan Humphrey, IT Director at Codemasters
