Abstract
Embodiments relate to saving data upon loss of power. An aspect includes sizing a write cache buffer based on parameters related to carrying out this emergency data save procedure. A computer program product for allocating a write cache on a storage controller includes retrieving, at run-time by a processor, one or more operating parameters of a transfer logic used in a power-loss save of the write cache. The one or more operating parameters include an instance-specific process speed of the transfer logic which is retrieved as bin data. A size for the write cache on the storage controller is determined, based on the one or more operating parameters. A write cache, of the determined size, is allocated from a volatile memory coupled to the storage controller.
