General Settings Chapter 4, Xgig TraceControl Capture Configuration
Xgig Analyzer User’s Guide 97
The Xgig1000 systems with 16G FC functionality support a link speed of 4.2500, 8.5000, or
14.0250 Gbps. It also includes an Auto option for ports used in Analog Passthrough. This is the
default setting. The auto-detect option automatically detects the link speed when the analyzer is
idle. Once a capture is started, the auto-detect feature does not change the current analyzer speed if
the link does change. The data rate will be fixed by the analyzer during capture.
SAS/SATA Link Speeds
For 3G SAS/SATA blades, the link speed can be set to
1.5000 Gbps
,
3.0000 Gbps
, or
Auto
. For
example, select the 3.0000 Gbps option from the pull-down menu to set the link speed to 3.0000
Gbps.
For 6G SAS/SATA blades and systems, the link speed can be set to the highest rate supported by
the blade containing the ports, a supported lower rate, or one of the
Auto
selections. The Xgig 6G
SAS/SATA Wide-Port/4x Blade, the 6G SAS/SATA Narrow blade, and the LX and LXP fixed-port
systems support 1.5000 Gbps, 3.0000 Gbps, and 6.0000 Gbps. For example, select the
3.0000
Gbps SAS option from the Link Speed pull-down menu to set the link speed to 3.0000 Gbps.
These blades and systems also have an auto-detect option, which will automatically detect the idle
link speed between 1.5000 Gbps, 3.0000 Gbps, and 6.0000 Gbps.
The Auto options available for 6G SAS/SATA blades and systems are
SAS 6/3/1.5G & SATA 3/
1.5G and SATA 6/3G. For the Auto options, no actual negotiation or handshake takes place
between the analyzer and any external device – the blade ports merely detect the data speed from
the speed negotiation sequence happening on the idle link. The
Auto options can automatically
determine the idle link speed only if the Xgig ports see the link initialization activities that take
place (for example, OOB and speed negotiation events). If link initialization sequence does not
happen while an
Auto
option is set, the blade will retain its existing speed. For example, select the
1.5000 Gbps option for the Link Speed in the TraceControl Configuration window to set the link
speed to 1.5000 Gbps. Then select the
Auto (SAS 6/3/1.5G & SATA 3/1.5G)
option for the Link
Speed. If no link initialization happens, the speed of the blade will still be 1.5000 Gbps. The
auto-detect option automatically detects the link speed when the analyzer is idle. Once a capture is
started, the auto-detect feature does not change the current analyzer speed if the link does change.
The data rate will be fixed by the analyzer during capture.
For 12G SAS blades, the link speed can be set to the highest rate supported by the blade containing
the ports, a supported lower rate, or one of the
Auto
selections. The Xgig5000 12G SAS Wide Port
blade and the Xgig1000 12G SAS blade support a link speed 3.0000, 6.0000, or 12.0000 Gbps.
These blades and systems also have an auto-detect option, which will automatically detect the idle
link speed between 3.0000 Gbps, 6.0000 Gbps, and 12.0000 Gbps.
The Auto options available for 12G SAS blades are
Auto (SAS 12/6G)
,
Auto (SAS 12/6/3G)
, and
Auto (SAS 6/3G) .
