~4000. 2016-12-09 · AFM allows you to create associations from a local Spectrum Scale cluster to a remote cluster or storage, and to define the location and flow of file data between sites. The implementation options for AFM are highly flexible and can be used to solve a range of customer use cases.

IBM Spectrum Scale™ meets these challenges as a parallel high-performance solution with global file and object data access for managing data at scale with the distinctive ability to perform archive and analytics in place. Read the data sheet (PDF, 391 KB)

Flash Cache metadata migration IBM Spectrum Scale enables low-latency read and write access to data from anywhere in the world using AFM distributed routing and advanced caching technology. AFM expands the IBM Spectrum Scale global namespace across geographical distances, providing fast read and write performance with automated namespace management. As data is written or Spectrum Scale Global Data Sharing —Remote file system mount (cross-cluster-mount) allows to share files between site synchronously at high speeds —IBM Spectrum Scale Active File Management (AFM) allows to share files asynchronously between sites • Files are globally visible and only locally present when accessed or pre-fetched 2021-03-04 · Occurs in IBM Spectrum Scale RAID configurations involving multiple log groups, such as IBM Spectrum Scale Erasure Code Edition or ESS 3000, that experience repetitive node shutdowns or network partitioning affecting a small subset of nodes in the cluster. Workaround: Restart the daemon.

This topic provides an overview of technical details, while the restrictions are listed in the IBM Spectrum Scale FAQ in IBM® Knowledge Center. Active file management (AFM) uses a home-and-cache model in which a single home provides the primary storage of data, and exported data is cached in a local GPFS file system.

Spectrum Scale File Audit Logging logs all file operations like create, delete modify etc. in a central place. These logs can be used to track user access to the file system. AFM. Files can be compressed in AFM and AFM-DR filesets. Spectrum Scale 5.0 also made improvements for load balancing across AFM gateways.
