6Gb/s MegaRAID SAS RAID Controllers User Guide October 2013

Chapter 1: Overview

This document is the primary reference and user’s guide for the LSI® MegaRAID® SATA+SAS RAID controllers based on the 6Gb/s SAS/SATA RAID on a chip devices. This document contains complete installation instructions for these RAID controllers and includes specifications for them.

1.1 Overview

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.

Overview Overview

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

1.1.1 MegaRAID 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.

1.5 Benefits 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.

1.5.1 PCIe 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.

Benefits of the SAS Interface

Overview

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.

1.5.2 Operating 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 October 2013

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.

1.6.3 SATA 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.
