Active flash is the latest enhancement to Hitachi Dynamic Tiering (HDT). After the active flash feature is enabled, HDT pools with FMD or SSD in the top tier can adapt much more quickly to workload changes. When previously inactive pages suddenly become busy, active flash can promote them immediately to fast disk, without waiting for the end of the current HDT monitoring cycle.
