Abstract

When a host I/O request is received, logging each transaction that is to be performed to process the host I/O request includes selecting from between a first persistent storage and a second persistent storage to identify the location to which the transaction is to be logged, and then logging the transaction to the selected location. The selection may be made based on a log policy indicating percentages of transactions to be logged to each of the first persistent storage and the second persistent storage. The percentages may be calculated periodically based on a dynamically measured performance characteristic of the first data storage, such as latency. All transactions for host I/O requests below a threshold minimum size, and/or all transactions for host I/O requests received while the current system throughput is below a minimum system throughput, may be logged to the first persistent storage.
