The read request is forwarded to a source physical volume of a device stack and a write request is forwarded to a destination physical volume of the device stack. Responsive to detecting that the read request has been received by the source physical volume of the device stack and the write request has been received by a destination physical volume of the device stack, the driver of the source physical volume or the driver of the destination physical volume construct a copy-offload request to be sent to a storage device, the copy-offload request comprising the read request, the write request, and the copy descriptor. The copy-offload request is subsequently sent to the storage device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Copy-offload on a device stack","description":"A read request, a write request, and copy descriptor are constructed and sent to logical volumes of a device stack to complete a copy-offload operation between a source logical volume and a destinatio","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9715351","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
