Invalid Speed Negotiation
Invalid SNW-1
This counter increments when the analyzer does not receive ALIGN(1)
primitives from one or both ends of a SAS link at 1.5 Gbps during
SNW-1 window of the SAS speed negotiation sequence.
Invalid SNW-2
This counter increments 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.
Invalid SNW-3
This counter increments when the analyzer receives no SAS-2 SNW-3
phy capabilities bits during SNW-3 window of the SAS speed
negotiation sequence.
Invalid Final-SNW (1.5 Gbps)
This counter increments when the analyzer does not receive ALIGN(1)
primitives from one or both ends of a SAS link at 1.5 Gbps rate during
Final-SNW window of the SAS speed negotiation sequence.
Invalid Final-SNW (3.0 Gbps)
This counter increments when the analyzer does not receive ALIGN(1)
primitives from one or both ends of a SAS link at 3.0 Gbps rate during
Final-SNW window of the SAS speed negotiation sequence.
Invalid Train-SNW
This counter increments when any Invalid Train-SNW event is
detected, regardless of the speed or parameters set for the speed
negotiation.
ATT (Actual Training time) outside
spec
This counter increments when an ATT outside spec event is detected.
The event is set when the measured value of ATT is not within TLT
(Training Lock Time) which is defined to be 28497920 OOBI or ~
18.998613 ms.
RCDT (Rate Change Delay Time)
outside spec
This counter increments when an RDCT outside spec event is
detected. A SAS device shall send D.C Idle for 750000 OOBI (nominal
value = 500 us) during the RCDT phase of a speed negotiation window
time. The event is set when the measured RCDT time falls within this
range RCDT time <= 492.5 us or RCDT time >= 507.5 us.
SNTT (Speed Negotiation
Transmit time) outside spec
This counter increments when an SNTT outside spec event is
detected. A SAS device shall send ALIGN(0) or ALIGN(1) for 163840
OOBI (nominal value = 109.2 us) during the SNTT phase of a SAS
speed negotiation window time. The event is set when the measured
SNTT time <= 102.5 us or SNTT time >= 117.5 us.
SATA speed negotiation failed
This event is set when speed negotiation is not successful on a SATA
link.
Phy Reset
SAS Phy Reset
The counter increments when the physical link is reset.
