The Global Setting "AutoAlign"
AutoAlign is a global setting that may be on or off depending on the type of device
you are emulating. There is an AutoAlign setting for SAS and one for SATA - for
example, "set AutoAlignSAS = ON" and "set AutoAlignSATA=OFF."
SAS - Sends AutoAligns every 2048 dwords.
SATA - Sends AutoAligns every 256 dwords.
If you plan to set and reset AutoAlign in the middle of traffic generation, then you need to
know what the defaults are for AutoAlign. The defaults are as follows:
For SATA host/device emulation, then
•
AutoAlignSATA is assumed to be ON
•
AutoAlignSAS is assumed to be OFF.
For SAS emulation, then the assumptions are opposite:
•
AutoAlignSATA is assumed to be OFF
•
AutoAlignSAS is assumed to be ON
For STP,
•
AutoAlignSAS and AutoAlignSATA are assumed to be ON
