Hardware Intel® Integrated RAID Module SROMBSASMR (AXXROMBSASMR) Technical Product Specification

2.7 Supported Device Technology

2.7.1 Support for Hard Disk Drive Devices

The Intel

Integrated RAID Module SROMBSASMR integrates four internal high-performance

SAS/SATA 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 via SATA commands.

2.7.2 SAS Expander Support

The Intel

Integrated RAID Module SROMBSASMR supports LSI* expanders, Vitesse* SAS

expanders and PMC* expanders that are used as a component in Intel enclosures. Other

expanders may be supported post launch, based on market conditions and customer

requirements.

2.7.3 Support for Non-Hard Disk Drive Devices

Because SAS-based non-hard drive devices were not available when this module 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

Integrated RAID Module

SROMBSASMR Tested Hardware and Operating System List.

2.7.4 Enclosure Management Support

The Intel

Integrated RAID Module SROMBSASMR supports SES2 enclosure management

using in-band signaling with expander-based backplanes and out-of-band signaling through I

bus with direct-connect non-expander backplanes.
