چکیده
Overview If ALIGNs or NOTIFYs are corrupted, but they are replaced in the data stream by expander(s) with valid ERROR primitives, the elasticity buffer of an expander or the frame recipient could overflow at a later time. If the expander determines that its elasticity buffer is full and it is expecting an ALIGN, it should be allowed to delete the invalid dword (assuming it might have been an ALIGN) rather than replace it with an ERROR. It should only do this when absolutely required, however, since an error in one dword might not show up until a subsequent dword (a characteristic of 8b10b).

If ALIGNs or NOTIFYs are corrupted, but they are replaced in the data stream by expander(s) with valid ERROR primitives, the elasticity buffer of an expander or the frame recipient could overflow at a later time. If the expander determines that its elasticity buffer is getting full and it is due an ALIGN, it should be allowed to choose to delete the invalid dword (assuming it might have been an...

This should not confuse a SAS-1.1 receiver, which is supposed to only honor the first SOAF it sees. As noted by Jeff Gauvin (LSI), the SL_IR state machine in SAS-1.1 (which handles IDENTIFY address frames) differs from the SL_RA state machine (which handles OPEN address frames) in its handling of unexpected address frames and SOAFs before EOAFs. SL_IR only honors the first SOAF it sees, while S...

متن کاملSubject: Sas-1.1, Protocol for Changing Driver Amplitude
Introduction This proposal provides a method for SATA-capable SAS initiator or expander devices to handshake with SATA devices capable of both SATA and SAS transmission amplitudes such that the OOB sequence results in both devices operating at the optimum amplitude on an operation physical link. Also, this proposal addresses two additional issues. The first could occur when a SAS/SATA initiator...
