The MegaRAID 6Gb/s SAS RAID controllers are high-performance intelligent PCI Express® (PCIe®)-to-SATA+SAS controllers with RAID control capability. The MegaRAID 6Gb/s SAS RAID controllers provide reliability, high-performance, and fault-tolerant drive subsystem management. They are an ideal RAID solution for the internal storage of workgroup, departmental, and enterprise systems. The MegaRAID 6Gb/s SAS RAID controllers offer a cost-effective way to implement RAID in a server.
SAS technology brings a wealth of options and flexibility with the use of SAS and SATA devices within the same storage infrastructure. However, SAS devices and SATA devices bring individual characteristics that make each one a more suitable choice depending on your storage needs. MegaRAID controllers offer the flexibility to combine these two similar technologies on the same controller and within the same enclosure.
NOTE |
You can have both SAS drives and SATA drives within the same virtual |
|
drive, too; however, the practice is strongly discouraged. |
LSI offers a family of MegaRAID SATA+SAS RAID controllers that address the needs for both internal and external solutions. The MegaRAID 6Gb/s SAS RAID controllers are based on the LSI first-to-market SAS IC technology and proven MegaRAID technology. As second-generation PCIe RAID controllers, these controllers address the growing demand for increased data throughput and scalability requirements across midrange and enterprise-class server platforms. These controllers provide these features:
6Gb/s Serial Attached SCSI (SAS) performance
6Gb/s SATA III performance
Eight-lane, 5 GT/s PCIe host interface
1.1.1MegaRAID SATA+SAS Controllers with Disk Encryption Support
The MegaRAID SAS 9260DE-8i RAID controller and the MegaRAID SAS 9280DE-8i RAID controller offer data security using disk encryption. This feature offers the ability to encrypt data on drives and use disk-based key management to provide data security. This solution provides data protection in the event of theft or loss of physical drives. With self-encrypting drives, if you remove a drive from its storage system or the server in which it is housed, the data
on that drive is encrypted and is useless to anyone who attempts to access without the appropriate security authorization.
For more information about self-encrypting drives, refer to the MegaRAID SAS Software User Guide on the MegaRAID Universal Software Suite CD.

1.1.3SAS/SATA Standards and Communication Protocols
MegaRAID SATA+SAS controllers support the ANSI® Serial Attached SCSI standard, version 2.0. In addition, the controller supports the SATA III protocol defined by the Serial ATA specification, version 3.0. Supporting both the SAS interface and the SATA interface, the SAS controller is a versatile controller that provides the backbone of both server and high-end workstation environments.
Each port on your MegaRAID SAS RAID controller supports SAS devices, SATA devices, or both, by using the following protocols:
SAS Serial SCSI Protocol (SSP), which enables communication with other SAS devices
SATA, which enables communication with other SATA devices
Serial Management Protocol (SMP), which communicates topology management information directly with an attached SAS expander device
Serial Tunneling Protocol (STP), which enables communication with SATA devices through an attached expander

Low-end, internal SATA configuration: In this configuration, use the RAID controller as a high-end SATA, SATA II,
or SATA III compatible controller that connects up to eight drives either directly or through a port expander. This configuration is mostly for low-end or entry servers. An out-of-band I2C bus provides enclosure management. Side bands of both types of internal SAS connectors support the SFF-8485 (SGPIO) interface.
Midrange internal SAS configuration: This configuration is like an internal SATA configuration, but with high-end SAS drives. This configuration is more suitable for low-range to midrange servers.

Benefits of the SAS Interface |
1.5Benefits of the SAS Interface
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 Fibre Channel, and it is the future mainstay of the enterprise and high-end workstation storage markets. SAS offers a higher bandwidth per pin than parallel SCSI, and it 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 when compared to parallel SCSI.
SAS controllers leverage a common electrical and physical connection interface that is compatible with Serial ATA technology. The SAS protocols and the SATA III protocols use a thin, 7-wire connector instead of the 68-wire SCSI cable or 26-wire ATA cable. The SAS/SATA III connector and cable are easier to manipulate, allow connections to smaller devices, and do not inhibit airflow. The point-to-point SATA III architecture eliminates inherent difficulties created by the legacy ATA master-slave architecture, while maintaining compatibility with existing ATA firmware.
1.5.1PCIe Architecture
PCIe is a local bus system designed to increase data transfers without slowing down the central processing unit (CPU). You can install MegaRAID PCIe RAID controllers in PCIe computer systems with a standard bracket type. With these controllers in your system, you can connect SAS devices and SATA III devices over the bus.
NOTE |
This controller is a PCIe x8 card, and it can operate in x8 or x16 slots. |
|
Some PCIe slots, however, support only PCIe graphics cards; if the |
|
remote mount board is installed in one of these slots, the controller |
|
will not function. Refer to the guide for your motherboard for |
|
information about the PCIe slot. |
PCIe goes beyond the PCI specification in that it is intended as a unifying I/O architecture for various systems: desktops, workstations, mobile devices, servers, communications, and embedded devices.
1.5.2Operating System Support
The MegaRAID 6Gb/s SAS RAID controllers support the following operating systems:
Windows® 2000, Windows XP, Windows XP x64, Windows Server® 2003 (x86), Windows Server 2003 (x64), Windows Vista®, Windows Server 2008, and Window Server 2012
Red Hat® Linux®
SuSE® SLES
Novell® NetWare®
SCO® OpenServer®
SCO UnixWare®
Solaris®
FreeBSD®
VMware®
Refer to the MegaRAID SAS Device Driver Installation User Guide for more information about the drivers. To download the latest operating system drivers, go to: http://www.lsi.com/cm/DownloadSearch.do.
The MegaRAID 6Gb/s SAS RAID controllers use Fusion-MPT architecture for all major operating systems, thinner drivers, and better performance.

6Gb/s MegaRAID SAS RAID Controllers User Guide |
Overview |
October 2013 |
Summary of 6Gb/s MegaRAID SATA+SAS RAID Controller Characteristics |
The maximum numbers in the previous table depend on how many physical devices you have connected to the RAID controller. For example, the maximum number of drive groups is equal to the number of drives that are supported by the controller. Thus, for the MegaRAID SAS 9240-4i RAID controller, the maximum number of drive groups per controller is 16, which is based on the maximum number of physical devices that you can connect. In addition, the maximum number of hot spares per controller is equal to the maximum number of drives per controller.
Although you can have up to 16 virtual drives per drive group, and up to 128 drive groups on most of the controllers, a limit of 64 virtual drives exists on those controllers.
These RAID controllers support 64-bit logical block addressing (LBA), which makes it possible to connect a large number of drives to the RAID controller, directly and through expanders. However, the actual number of drives that you can attach depends on the limits listed in this table rather than by actual RAID volume capacity.
1.6.3SATA III Features
The following list describes the SATA III features of the RAID controllers:
They support SATA III data transfers of 3Gb/s (for LSISAS2108-based controllers) and 6Gb/s (for LSISAS2208-based controllers).
They support STP data transfers of 3Gb/s.
They provide a serial, point-to-point storage interface.
They simplify cabling between devices.
They eliminate the master-slave construction used in parallel ATA.
They permit addressing of multiple SATA targets through an expander.
They permit multiple initiators to address a single target (in a failover configuration) through an expander.
1.6.4PCIe Performance
The following list describes the PCIe performance features of the RAID controllers:
They provide a PCIe interface that does the following:
—Supports a dedicated PCIe bus.
—Supports x8 lane configuration.
—Supports transfer rates of up to 5GT/s (4Gb/s) per lane.
—Complies with the PCI Express specification, Revision 2.0, and the Serial ATA specification, version 3.0.
They provide unequaled performance through the Fusion-MPT architecture.
They provide high throughput and low CPU utilization to offload the host processor.
1.6.5Usability Features
The following list describes the usability features of the RAID controllers:
They simplify cabling with point-to-point, serial architecture.
They support smaller, thinner cables that do not restrict airflow.
They provide drive spin-up sequencing control.
They provide one LED signal for each PHY to indicate link activity (this is a fault LED only for controllers with internal port connectors).
NOTE |
The MegaRAID SAS 9280-8e RAID controller and the MegaRAID SAS |
|
9280DE-8e RAID controller do not have LEDs to indicate link activity. |

6Gb/s MegaRAID SAS RAID Controllers User Guide |
Overview |
October 2013 |
Summary of 6Gb/s MegaRAID SATA+SAS RAID Controller Characteristics |
They provide an I2C interface for enclosure management.
They support the internal SAS Sideband signal SFF-8485 (SGPIO) interface.
1.6.6Flexibility Features
These features increase the flexibility of the RAID controllers:
They support a Flash ROM interface, a nonvolatile static RAM (NVSRAM) interface, and a pipelined synchronous burst SRAM (PSBRAM) interface.
They offer a flexible programming interface to tune I/O performance.
They permit mixed connections to SAS targets or SATA III targets.
They leverage compatible connectors for SAS connections and SATA III connections.
They permit grouping of up to four PHYs in a single quad port to form a wide port.
They permit programming of the World Wide Name.
1.6.7Drive Roaming
Drive roaming occurs when the drives are changed to different ports on the same controller. When the drives are placed on different channels, the controller detects the RAID configuration from the configuration data on the drives.
Configuration data is saved in both the NVRAM on the RAID controller and on the drives attached to the controller. This action maintains the integrity of the data on each drive, even if the drives have changed their physical device ID.
NOTE |
If you move a drive that is being rebuilt, the rebuild operation restarts; |
|
it does not resume from the stopping point. |
Follow these steps to use the drive roaming feature:
1.Turn off the power to the server and all drives, enclosures, and system components. Disconnect the power cords from the system.
2.Open the host system by following the instructions in the host system technical documentation.
3.Move the drives to different positions on the backplane to change the targets.
4.Determine the SAS target requirements.
5.Perform a safety check.
a.Make sure that the drives are inserted correctly.
b.Close the cabinet of the host system.
6.Reconnect the power cords to the system.
7.Turn on the power to the system.
The controller then detects the RAID configuration from the configuration data on the drives.
1.6.8Drive Migration
Drive migration is the transfer of a set of drives in an existing configuration from one controller to another. The drives must remain on the same channel and must be reinstalled in the same order as in the original configuration. The controller to which you migrate the drives cannot have an existing configuration.
NOTE |
Partial configurations, which include individual virtual drives, can |
|
be migrated. |
NOTE |
Drive roaming and drive migration cannot be supported at the |
|
same time. |

Overview |
October 2013 |
Hardware Specifications |
Follow these steps to migrate drives:
1.Make sure that you clear the configuration on the system to which you migrate the drives to prevent a configuration data mismatch between the drives and the NVRAM.
NOTE |
When you migrate drives, move only the drives that make up the |
|
virtual drive (not all of the drives in a drive group), so that you do not |
|
see an NVRAM mismatch error (providing a configuration is on the |
|
destination controller). The NVRAM mismatch error appears only if you |
|
move all of the drives to the other controller. |
2.Turn off power to the server and all drives, enclosures, and system components. Disconnect the power cords from the systems.
3.Open the host system by following the instructions in the host system technical documentation.
4.Either remove the SAS cable connectors from the internal drives, or remove the shielded cables from the external drives that you want to migrate.
a.Make sure that pin 1 on the cable matches pin 1 on the connector.
b.Make sure that the SAS cables conform to all SAS specifications.
5.Remove the drives from the first system, and insert them into the drive bays on the second system.
6.Connect the SAS cables to the drives in the second system.
7.Determine the SAS target requirements.
8.Perform a safety check.
a.Make sure that all of the cables are attached correctly.
b.Make sure that the RAID controller is installed correctly.
c.Close the cabinet of the host system.
9.Reconnect the power cords to the system.
10.Turn on the power to the system.
The controller detects the RAID configuration from the configuration data on the drives.
1.7Hardware Specifications

Unpack and remove your RAID controller. Inspect it for damage. If it appears damaged, or if any of the following items are missing, contact your LSI Customer and Technical Support representative. The RAID controller is shipped with the following items:
—A CD that contains an electronic version of this user’s guide, and other related documentation
—A license agreement
—Warranty information
2.Turn off the power to the system.
Turn off the power to the computer, and disconnect the AC power cord. Remove the computer cover. Refer to the system documentation for instructions. Before you install the controller, make sure that the computer is disconnected from the power and from any networks.
3.Review the RAID controller jumpers and connectors.
The jumpers are set at the factory, and you usually do not need to change them. See Chapter 3, MegaRAID SAS RAID Controller Characteristics, for diagrams of the MegaRAID 6Gb/s SAS RAID controllers that show their jumpers and connectors.
4.Install the RAID controller.
Select a PCIe slot, and align the controller’s PCIe bus connector to the slot. Press down gently, but firmly, to make sure that the card is seated correctly in the slot. Secure the bracket to the computer chassis with the bracket screw. The following figure shows the installation of the MegaRAID SAS 9260-8i RAID controller in a PCIe slot.
ATTENTION |
If your RAID controller has a battery backup unit (BBU) attached, do |
|
not press down on the BBU when you insert the card. |
NOTE |
This controller is a PCIe x8 card, and it can operate in x8 or x16 slots. |
|
Some PCIe slots, however, support only PCIe graphics cards; if the |
|
remote mount board is installed in one of these slots, the controller |
|
will not function. Refer to the guide for your motherboard for |
|
information about the PCIe slot. |

5.Configure and install the SAS devices, the SATA devices, or both in the host computer case. Refer to the documentation for the devices for any preinstallation configuration requirements.
6.Connect the RAID controller to the devices.
Use SAS cables to connect SAS devices, SATA devices, or both to the MegaRAID 6Gb/s SAS RAID controller. See Section 2.5, SAS Device Cables and Connectors, for SAS cable and connector information. See Section 2.5.1, Connecting a SAS RAID Controller with Internal Connectors to the Drives, for information about connecting the controller to the drives.
The maximum cable length is 10 meters (393.37 in.). You can connect one device per SAS PHY unless you use an expander.
System throughput problems can occur if the SAS cables are not the correct type. To minimize the potential for problems, use the following guidelines:
—Use cables no longer than 10 meters (393.37 in.). (Use shorter cables, if possible.)
—Use cables that meet the SAS specification.
—Route the SAS cables carefully.
7.Turn on the power to the system.
Reinstall the computer cover, and reconnect the AC power cords. Turn on power to the host computer. Make sure that the power is turned on to the SAS devices, SATA devices, or both before or at the same time that the power is turned on to the host computer. If the computer is powered on before these devices, the devices might not be recognized.
During boot, a BIOS message appears. The firmware takes several seconds to initialize. The configuration utility prompt times out after several seconds. The second portion of the BIOS message shows the MegaRAID 6Gb/s SAS RAID controller number, firmware version, and cache SDRAM size. The numbering of the controllers follows the PCI slot scanning order used by the host motherboard.

You can view the supported operating systems and download the latest drivers for RAID controllers from the LSI website.
For information about installing the driver, refer to the MegaRAID SAS Device Driver Installation User Guide on the MegaRAID Universal Software Suite CD. Be sure to use the latest service packs provided by the operating system manufacturer and to review the readme file that accompanies the driver.
2.4After Installing the RAID Controller
After you install the MegaRAID 6Gb/s SAS RAID controller, you must configure the controller and install the operating system driver. The MegaRAID SAS Software User Guide instructs you on the configuration options and how to set them on your MegaRAID 6Gb/s SAS RAID controller. The MegaRAID SAS Device Driver Installation User Guide provides detailed installation instructions for operating system drivers.
2.5SAS Device Cables and Connectors
This section describes the cables and the connectors used on the MegaRAID SAS controllers and provides step-by-step instructions for connecting SAS drives, SATA drives, or both to the MegaRAID SAS RAID controller. The SAS protocol and the SATA protocol use a thin, 7-wire connector instead of the 68-wire SCSI cable or the 40-wire ATA cable.
NOTE |
Use only straight SAS cables, not crossover SAS cables. |
The following figure shows the SAS cable that connects the internal connectors on a SAS RAID controller to SAS drives, SATA drives, or both.
