Routability Internal Mini SAS Cable Assemblies

has tested these assemblies in folded configurations, and each fold impacts the at that location by approximately only 1 ohm, well within the tightest impedance specifications (and note that the impedance at each fold is not cumulative, but is only a variation at that point).Similarly, S-parameter performance metrics are not degraded, and the cable assemblies still pass Internal Mini SAS Cable criteria, even with multiple folds.  Should your design require any folding, be sure to restrain the cable with the appropriate cable clamps to  prevent repeated flexure at the folds. My supplier did not have any of these motherboards, nor any USB3.0 controllers, so I opted instead to drop the workstation board and rather invest in a dedicated Internal Mini SAS Cable controller and a motherboard with on-board USB3.0 support. From a financial perspective, this worked out to more or less the same as the original quotation but I believe the latter solution is the better one since the client can easily add two further SAS drives to the PC without needing to worry about the controller (unless he decided to go with SAS enclosures, which is a different animal all together). The STA objectives include a consistent connectivity management scheme in addition to the active copper and optical cable extensions supported by the new Internal Mini SAS Cable connector.
