Management Protocol (SMP), and Serial Tunneling Protocol (STP). The SSP protocol
enables communication with other SAS devices. STP allows the SAS controller to
communicate with SATA devices using the SATA commands.
SAS Expander Support
The Intel
®
SAS Controller RS25GB008 supports LSI* expanders and Maxim SAS
expanders, that are used as a component in Intel enclosures. Other expanders may be
supported post launch, based on market conditions and customer requirements.
Support for Non-Hard Disk Drive Devices
As SAS-based non-hard drive devices were not available when this controller was in
development, support for these devices will be determined as they become available. For
information on support for non-hard drive devices, see the Intel
®
SAS Controller
RS25GB008 Tested Hardware and Operating System List.
SAS Bus and ID Mapping
Devices on the SAS bus are persistently mapped based on a SAS address.
