Hello ,
 
This is regarding a confusion on SBP2 spec about contiguos data buffer.
According to Page number 14 and 15, under 4.4 Data Buffers, and page number 62, under 9.2 Data Transfer of SBP2 specs Rev 2 May 19,1998, even when p =0 in an ORB, it can have page boudaries according to the page_size (if page_size is nonzero), and without page boudaries if page_size is zero, and in figure 7, the data descriptor points to a data buffer start location where the first page boundary does not appear on page_size, which shows an offset on first page.
If there should be a offset which is described by the data_descriptor then what describes the base address for the same ? or is there a bug in the figure 7, so that the data_descriptot shows the base address/starting address and from the first page onwards, every page has full page_sige only.
 
Please advice ASAP since we are in mid of designing the SBP2 protocol for our customer and we are stuck in between.
 
Thanks and regards,
