Abstract
A method and a system for use in managing data storage is disclosed. Data storage is managed in a data storage system comprising a first and a second storage processor and a plurality of data storage devices. The first and the second storage processor having respective caches configured to mirror each other. A write I/O is received in the data storage system, wherein the write I/O is an operation for updating data storage in the data storage system. Load associated with the first and second storage processor in the data storage system is determined. The cache is bypassed and write I/O is delivered to the plurality of data storage devices in the data storage system in response to determining a heavy load associated with the first and second storage processor in the data storage system.
