Abstract

One or more aspects of the present disclosure relate to performant destaging of write pending (WP) data to disk. In embodiments, an input/output (IO) workload is received at a storage array. Additionally, the IO workload can include an IO request with a random write request. Further, a write destage context for write-pending (WP) data corresponding to the random write request can be generated by a data services engine of the storage array. In addition, using the write destage context, a disk adapter (DA), at a backend of the storage array, is enabled to destage write-pending (WP) data without reading from a target write location of the random write request on a storage device on the storage array.
