Supported Device Technology
The various device technologies supported by the Intel
®
Integrated RAID Module
RMS25KB080, RMS25KB040, RMS25JB080 and RMS25JB040 is described in the
subsections that follow.
Support for Hard Disk Drive Devices
Intel
®
Integrated RAID Module RMS25KB080, RMS25KB040, RMS25JB080 and
RMS25JB040 integrates four or eight internal high-performance SAS/SATA III ports that
support SAS and enterprise-class SATA hard drives. Each port supports both SAS and
SATA devices using the SAS Serial SCSI Protocol(SSP), Serial Management Protocol
(SMP), and Serial Tunneling Protocol (STP). The SSP protocol enables communication
with other SAS devices. STP allows the SAS RAID controller to communicate with SATA
devices using the SATA commands.
SAS Expander Support
The Intel
®
Integrated RAID Module RMS25KB080, RMS25KB040, RMS25JB080 and
RMS25JB040 supports LSI* expanders, Vitesse SAS expanders, and PMC expanders that
are used as a component in Intel and 3rd party enclosures. Other expanders may be
supported post launch, based on market conditions and customer requirements.
