Major Release: IBM Aspera Enterprise Server, Connect Server, Point-to-Point Client, and Desktop Client 3.7.3

We are pleased to announce the release of IBM Aspera Enterprise Server, Connect Server, Point-to-Point Client, and Desktop Client version 3.7.3 for Windows, Linux, Mac OS, AIX, Solaris x86 and Solaris SPARC. This new release provides enhanced security, expanded platform support, improved error handling, additional management capabilities, and a host of performance enhancements.

 

KEY NEW FEATURES

Enhanced Security & Access Controls

  • New checksum algorithms SHA-256, SHA-384, and SHA-512 can be utilized to ensure data integrity and authenticity.
  • Improved detection of potential Distributed Denial of Service attempts involving missing or slow SSL negotiation requests. The HTTP fallback daemon now automatically times out connections that do not send a request or are too slow.
  • FASP transfers run with ascp on AIX and Solaris can now use access key authentication.
  • Aspera now supports Kerberos for Hadoop Distributed File System (HDFS) transfers.
  • New fields are available in the AWS access keys to support AWS KMS server-side encryption and the INFREQUENT_ACCESS storage class.

Expanded Platform Support

  • Aspera A4, an optimized transfer engine based on FASP technology, is now supported on macOS. This upgraded executable is designed to handle large collections of small files, enables multi-threaded FASP transfers, TCP and UDP stream I/O, and memory usage control.
  • IBM Bluemix Swift and S3 storage are now supported and can be specified as an ATS connection along with Azure PAGE blob storage.
  • AIX and Solaris platforms now support  Watchfolders and the Aspera Watch Service.
  • Sync with S3 is now fully supported.
  • The Node API now supports access keys for IBM Bluemix S3 storage and Google Cloud Storage.

Improved Error Handling

  • Improved behavior of Watchfolders when a transfer session fails to start within a specified timeout.
  • Improved error messages when watchd encounters invalid paths or is blocked by permission settings.
  • Sync now has a two-minute timeout, enabling it to exit gracefully in the rare cases when it does not receive a proper shutdown sequence.
  • Sync run in bidirectional mode with modification times preserved no longer reports conflicts due to directory modification times.

Additional Management Capabilities

  • Persistent ascp sessions can now accept management control messages sent from a server to the remote machine.
  • Specific events can now be requested by ID using the Node API.
  • The Node API now supports file locking.
  • A new Sync option, --cooloff-max=time, can be specified so that a one-time async session waits for a file to stop changing within the cooloff interval before it synchronizes the file.

Performance Enhancements

  • The performance of the FASP protocol has been enhanced on the AIX and Solaris platforms. Compared to prior releases, unencrypted CPU-bound transfers may see an increase of up to 100% in overall throughput; and encrypted CPU-bound transfers may see an increase in overall throughput of up to 20%.
  • Faster file deletion in OpenStack Swift storage.
