Active file management (AFM) is a scalable, high-performance, file system caching layer integrated with the GPFS™ cluster file system. AFM allows you to create associations from a local GPFS cluster to a remote cluster or storage, and to define the location and flow of file data to automate the management of the data. Spectrum ScaleAFM-based Async Disaster Recovery functionality. AFM migration statistics, better estimation on time to completion. Generic backend support including replication to COS or caching. IBM Spectrum Scale 4.2 AFM limitations include: If you change an AFM SW/IW home export from Kernel NFS or CNFS to the new IBM Spectrum Scale CES in 4.1.1 or later, AFM does not recognize the home. The best way to manage this situation is to run the mmafmctl failover command.
•rsync(or a variation of this) •AFM Spectrum Scale AFM Deep Dive July 5, 2018 by Lindsay Todd, posted in Uncategorized This is a talk I did for the “ Accelerate with IBM Storage ” webinar on Spectrum Scale’s Active File Management (AFM) capability. Active file management (AFM) is the patented technology that is integrated with IBM Spectrum Scale and ESS nodes. It is a scalable, high-performance, file system caching layer integrated with the GPFS™ cluster file system which is the operating system of IBM Spectrum Scale.
