MULTI-THREADED TRANSACTION LOG FOR PRIMARY AND RESTORE/INTELLIGENCE

摘要

A unified system provides primary storage and in-line analytics-based data protection. Additional data intelligence and analytics gathered on protected data and prior analytics are stored in discovery points. The disclosed system implements multi-threaded log writes across primary and restore nodes with write gathering across file systems; nested directories such as may be used for storing virtual machine files, where every subdirectory has an associated file system for snapshot purposes; and cloning objects on demand with background metadata and data migration.

1. A method for processing in a data-intelligent storage system that includes a primary node storing primary data and in-line analytics, a restore node storing further analytics and intelligence, and a protection and analytics (PART) node, comprising the steps of:
receiving access requests from multiple concurrently executing threads within the PART node; assigning a transaction identifier (ID) to the access requests; and logging the access requests at the PART node in a random access, multithreaded log; and subsequently forwarding the access requests from the PART node to the primary node and restore node.
