It is determined whether the target location is mapped to physical storage. Responsive to determining that the target location is not mapped to physical storage, performing first processing to service the write operation. The first processing includes sending the write operation along with a hint to a caching layer where the hint indicates to store zeroes to locations that do not include user data. The caching layer forms a data portion denoting data stored at a logical address subrange of the logical device. The logical address subrange includes the target location. The data portion includes the first data and zeroes stored at remaining locations of the logical address subrange not including user data. The data portion is stored in cache by the caching layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Techniques for zeroing non-user data areas on allocation","description":"Described are techniques for processing a write operation that writes first data to a target location of a logical address range of a logical device.
