Abstract
A method for efficiently processing write data from a storage controller to a striped storage volume is provided. The method includes receiving, by the storage controller, a host write request including a host write request size, calculating, by the storage controller, that a time to fill a stripe including the host write request is not less than a host guaranteed write time, and processing, by the storage controller, the host write request as a write-through host write request. The time to fill the stripe is a size of the stripe divided by a data rate of a host write stream comprising the host write request. The host guaranteed write time is the maximum latency that the storage controller guarantees host write requests are committed to one of a storage controller write cache and the striped storage volume.
