1 Overview

The Intel

®

RAID Module RMS2LL040 and RMS2LL080 provide reliable and fault-

tolerant disk subsystem management based on the Intel

®

Entry Hardware RAID (IR)

Stack. This is an ideal RAID solution for the internal large capacity storage needs of mid

to low-end servers and workstations for use by workgroups and departmental-sized

organizations or individuals. The Intel

®

RAID Module RMS2LL040 and RMS2LL080

offer a cost-effective way to implement RAID in a server for internal storage.

As the second generation PCI Express* storage adapters, the Intel

®

RAID Module

RMS2LL040 and RMS2LL080 address the growing demand for increased data

throughput and scalability requirements across mid to low-end servers and workstations.

The controller can be connected to up to four drives (RMS2LL040) or eight drives

(RMS2LL080) directly and allows the use of expanders to connect to additional drives.

For more information about the use of expanders, see the ANSI SAS Standard, version 2.0

specification.

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.

Benefits of SAS and SATA

SAS is a serial, point-to-point, 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 use 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.

The Intel

®

RAID Module RMS2LL040 and RMS2LL080 are intelligent custom board-to-

board PCI Express* 2.0 compliant interface RAID adapters with an integrated LSI*

LSISAS2008 Processor Chip, providing both a SAS controller and RAID engine. With

four (RMS2LL040) or eight (RMS2LL080) independent ports supporting 6-Gbps and 3

Gbps SAS data transfers using four or eight individual SAS/SATA connectors, this

controller supports up to 32 enterprise-class SAS or SATA devices and 64 logical drives.

The PCI Express* connector fits into a 50 pin connector capable of performance up to 5

The SAS RAID controllers support the SAS protocol as described in the Serial Att

ached

SCSI Standard, Version 2.0. The controllers also support 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.

Intel® RAID Module RMS2LL040 and RMS2LL080 Hardware User’s Guide 3

Protocol Support

Each port on the SAS controllers 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..

Operating System Support

• Windows Server 2008* R2 and Windows Server 2003*

• Red Hat* Enterprise Linux 5.0

• SuSE* Linux Enterprise Server 10 and 11

The operating systems supported may not be supported by your server board. See the

Hardware Installation

Requirements

• Intel

®

RAID Module RMS2LL040 and RMS2LL080, with the provided standoffs

• A host system with one available 50-pins PCI Express* 2.0 connector

• Resource CD, which contains drivers and documentation

• SAS or SATA 6.0 hard drives

• Four provided SAS/SATA cables (for cable requirements, see step 6 in “Installing

the RAID Module”)

Note: I

ntel Corporation strongly reco

mmends using an uninterruptible power supply (UPS).

Installing the RAID Module

To install the RAID Module, follow these steps:

1. Turn off the power to the system, all drives, enclosures, a

nd system components.

Remove the power cord(s).

2. Remove the server cover. For instructions, see your server system

documentation.

3. Insert the three barrel standoffs into the matching holes in the server/workstation

bo

ard. To locate the matching module card slot on your server/workstation board,

see your server/workstation board documentation.

The Intel

®

Server Board SR5520UR is shown for illustrative purpose. Actual

standoff hole locations could be different (see Figure 1).

4. Attach the Intel

®

RAID Module RMS2LL0x0 to the matching server/workstation

board connector, and press the module card firmly to engage the barrel standoffs

installed in step 3 (see Figure 1). The Intel

®

RAID Module RM2LL080 is shown

for illustrative purpose (see Figure 2).

Figure 1. Installing the Barrel Standoff

5. Press down gently but firmly to ensure that the card is properly se

ated in the

connectors, and then insert the three pin standoffs into the barrel standoffs

respectively ( see Figure 2).

Figure 2. Installing Intel

®

RAID Module RMS2LL0x0

6. Connect the SAS/SATA cables from the backplane (or hard drives) to the RAID

module

(see Figure 3). For information regarding connectin

g the recommended

Right-angle end or Vertical end of the SAS/SATA cable to the SAS connectors of

the controller, see

your server/workstation board or chassis documentation. Make

sure the cables are properly connected to the controller.

Note: System throughput problems can occur if non-standard SAS cables are used.

To

minimize the potential for problems:

✧ Use cables no longer than ten meters for SAS

and one meter for SATA. It is

better to use the shortest possible cables. The cable length should be reduced

by about one foot (.33 meters) if using a backplane.

✧ You may connect one device per SATA/SAS cable either as a device or as an

ex

pander.

AF003487

AF003489

Intel® RAID Module RMS2LL040 and RMS2LL080 Hardware User’s Guide 7

✧ Route SAS cables carefully.

✧ Use only “straight” SAS cables, not “c

ross-over” SAS cables. .
