Abstract
Aspects of the present disclosure relate to optimizing atomic operations in storage arrays by selectively enabling fabric-less mode based on device access patterns. In embodiments, whether multi-path software is enabled is determined, and device-level access control mappings are analyzed to identify candidates for fabric-less mode operation. For devices without multi-path software, a fabric-less mode is enabled when mapped to a single board, allowing atomic operations via software locks instead of fabric hardware. When multi-path software is enabled, the embodiments either leverage ALUA states to identify optimized paths or employ time series analysis using ARIMA models to predict IO access patterns. Fabric-less mode is activated when forecasting indicates localized access patterns, significantly improving response time and IOPS by avoiding fabric bandwidth constraints and hardware vendor limitations. The embodiments enable efficient atomic operations through CPU access to local memory, eliminating unnecessary fabric operations while maintaining data consistency across the storage array.
