1 Overview

The Intel® RAID Expander Card RES2SV240 offers high performance, high disk drive connectivity,scalability, and flexibility in various storage environments, and is an attractive alternative to other expensive and complex topologies. The SAS expander is ideal for high availability and scalable server clustering environments and front-end storage subsystems used in clusters, Storage Area Networks (SANs), and NetworkAttached Storage (NAS) environments. It is an optimal device for use in data centers and SANs, leveraging existing SCSI infrastructure for investment protection and ease of migration and implementation.

RAID Expander Card RES2SV240 is a 24-port, 6.0Gb/s Serial Attached SCSI

Intel (SAS) expander that enables the connection of up to 24 directly attached SAS or Serial ATA (SATA) devices. Each expander phy is individually configurable and performs SAS and SATA transfers based on the speed of the host or target at either 6.0Gb/s, 3.0Gb/s, or

1.5Gb/s.

The Intel increased data throughput and scalability requirements across entry level, midrange, and enterprise server platforms.

SATA and SAS are serial, point-to-point, device interfaces that use simplified cabling, smaller connectors, lower pin counts, and lower power requirements than parallel SCSI.

RAID Expander Card RES2SV240 addresses the growing demand for

Benefits of SAS and SATA

SAS is a serial, enterprise-level device interface that leverages the proven SCSI protocol set. SAS is a convergence of the advantages of SATA, SCSI, and FC, and is the future mainstay of the enterprise and high-end workstation storage markets. SAS offers a higher bandwidth per pin than parallel SCSI and improves signal and data integrity.

The SAS interface uses the proven SCSI command set to ensure reliable data transfers, while providing the connectivity and flexibility of point-to-point serial data transfers. The serial transmission of SCSI commands eliminates clock skew challenges. The SAS interface provides improved performance, simplified cabling, smaller connectors, lower pin count, and lower power requirements than parallel SCSI.

SAS controllers leverage a common electrical and physical connection interface that is compatible with Serial ATA technology. The SAS and SATA protocols support the use of a thin, 7-wire connector instead of the 68-wire SCSI cable or 40-wire ATA cable. The SAS/SATA connector and cable are easier to manipulate, connect to smaller devices, and do not inhibit airflow. The point-to-point SATA architecture eliminates difficulties created by the legacy ATA master-slave architecture, while maintaining compatibility with existing ATA firmware.

Intel® RAID Expander Card RES2SV240

The SAS/SATA functionality for the Intel® RAID Expander Card RES2SV240 is contained within the LSI* LSISAS2x24 24-Port Serial Attached SCSI/SATA Expander chip. This expander card has twenty-four independent ports supporting 6Gb/s, 3 Gb/s, or

1.5Gb/s SAS and SATA data transfers using six SFF-8087 mini-SAS connectors. This controller supports 4 inputs and 20 outputs configuration, or 8 inputs and 16 outputs configuration. This expander card is powered either from its standard PCI Express* x4 connector (with only power pins) to get power from motherboard PCI Express slot, or from its RA 4-pin power connector for remote cable power.

The expander card is designed to be compatible with the following Intel Controllers and Modules:

• Intel

Integrated RAID Module RMS2MH080

RAID Module RMS2AF080 and RMS2AF040

RAID Module RMS2LL080 and RMS2LL040

RAID Controller RS2BL080, RS2BL040, and RS2BL080DE

RAID Controller RS2MB044

RAID Controller RS2WC080 and RS2WC040

Integrated RAID Module SROMBSASMR

Note: Additional cable might need to be purchased for some of above adapters to connect.

Additional Intel® RAID Controllers and Modules may be supported. For the most up-todate list, see the Compatibility section under the link for this Intel at http://support.intel.com/support/motherboards/server/.

The expander card supports the SAS protocol as described in the Serial Attached SCSI Standard, Version 2.0. The card also supports the Serial ATA II (SATA II) protocol defined by the Serial ATA Specification, Version 1.0a and the Serial ATA II: Extension to the Serial ATA Specification, Version 1.1. SATA II is an extension to SATA 1.0a.

Protocol Support

Each port on the expander card supports SAS devices, SATA II devices, or both using SSP, SMP, STP, and SATA II as follows:

• Serial SCSI Protocol (SSP) to enable communication with other SAS devices.

• SATA II Protocol to enable communication with other SATA II devices.

• Serial Management Protocol (SMP) to share topology management information

with expanders.

• Serial Tunneling Protocol (STP) support for SATA II through expander interfaces.

• SAS protocol, described in the Serial Attached SCSI (SAS) Standard, version 2.0
