SAS -3, Speed Negotiation Decodes
TraceView uses timing values and other criterion to determine events reported for speed
negotiation using OOB signals. The description of how TraceView determines these events are
shown in the table below for SAS-3.

Speed Negotiation Decode
Event Description
SNW-2 Begin
This event marks the beginning of the SNW-2 window of the SAS
speed negotiation sequence.
SNW-2 End
This event marks the end of the SNW-2 window of the SAS speed
negotiation sequence.
Valid SNW-2 detected
This event is set when the analyzer receives ALIGN(1) primitives
from both ends of a SAS link at 3.0 Gbps during SNW-2 window of
the SAS speed negotiation sequence.
Invalid SNW-2 detected
This event is set when the analyzer does not receive ALIGN(1)
primitives from one or both ends of a SAS link at 3.0 Gbps during
SNW-2 window of the SAS speed negotiation sequence.
SNW-3 Begin
This event marks the beginning of the SNW-3 window of the SAS
speed negotiation sequence.
SNW-3 End
This event marks the end of the SNW-3 window of the SAS speed
negotiation sequence.
Valid SNW-3 detected
This event is set when the analyzer receives one or more SAS-2
SNW-3 phy capabilities bits transmitted as COMWAKE OOB signals
during SNW-3 window of the SAS speed negotiation sequence.
Invalid SNW-3 detected
This event is set when the analyzer receives no SAS-2 SNW-3 phy
capabilities bits during SNW-3 window of the SAS speed negotiation
sequence.
SNW-3 phy capabilities bits
Begin
This event is set to indicate the beginning of SNW-3 phy capabilities
bits transmission window during SNW-3.
SNW-3 phy capabilities bits End
This event is set to indicate the end of SNW-3 phy capabilities bits
transmission window during SNW-3.
SNW-3 phy capabilities bit
This event is set when a COMWAKE OOB signal is received during
the SNW-3 window to indicate the specific SNW-3 phy capabilities bit
received.
SNW-3 phy capabilities value
This event is set to indicate the 32-bit SNW-3 phy capabilities value
received during SNW-3 window. The 32-bit value has bit 0 (START
bit) as the MSB and bit 31 (PARITY bit) as the LSB.
Final-SNW (3.0 Gbps) Begin
This event marks the beginning of the Final-SNW speed negotiation
window at 3.0 Gbps rate.
Final-SNW (3.0 Gbps) End
This event marks the end of the Final-SNW speed negotiation
window at 3.0 Gbps rate.
Valid Final-SNW (3.0 Gbps)
detected
This event is set when the analyzer receives ALIGN(1) primitives
from both ends of a SAS link at 3.0 Gbps rate during Final-SNW
window of the SAS speed negotiation sequence.
