Hi, From the Lustre white paper, Lustre is designed and implemented to be an object-based storage system that says the Lustre protocol. As I know, there is also a draft of object-based storage command set from T10 that defines a common interface to access the OSD by issuing the SCSI commands. What is the difference between the Lustre''s and T10''s OSD command set and how much it is? Is it possible or feasible to change the Lustre protocol into T10''s osd command set proposal? Or, is there any plan or any project that is currently working on this kind of transfer? Thanks. Best regards, Yi-chang Zhuang
