Abstract
In one aspect, a system for indexing transactions over a shared bus is described. In various embodiments, the system includes a host controller and a plurality of storage devices in communication with the bus. Each of the storage devices is configured to store data. The bus facilitates communications between the host controller and the plurality of storage devices. A selected one of the storage devices is configured to function as a transaction indexer to monitor the bus and index and store selected transaction information associated with operations that occur over the bus. While the host controller may be arranged to configure the transaction indexer, the transaction monitoring, indexing and storing are performed substantially automatically by the transaction indexer without requiring further instructions from the host controller.
