1 12Gb/s Intel Overview

® RAID Controller

This document is the primary reference and user's guide for the Intel® RAID Controllers based on the 12Gb/s SAS/SATA RAID-on-a-chip (ROC) devices. This document contains complete installation instructions and specifications for these RAID controllers.

Overview

The 12Gb/s Intel ^® RAID Controllers are high-performance intelligent PCIe-to-SATA+SAS controllers with RAID control capability. The 12Gb/s Intel ^® 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 12Gb/s Intel ^® 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 devices 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. The 12Gb/s Intel ^® RAID Controller gives you the flexibility to combine these two similar technologies on the same controller, within the same enclosure, and in the same virtual drive.

Note: Carefully assess any decision to mix SAS drives and SATA drives within the same virtual drive. Although you can mix drives, the practice is strongly discouraged.

Intel offers a family of 12Gb/s Intel ^® RAID Controllers that address the needs for both internal and external solutions. The 12Gb/s Intel ^® 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:

• 12 Gb/s Serial Attached SCSI (SAS) performance
- 6 Gb/s SATA III performance
• Eight-lane, 8 GT/s PCIe host interface

12Gb/s Intel ^® RAID Controllers with Support for RAID Maintenance Free Back Units

The Intel ^® RAID Controller RS3DC0x0 supports the RAID Maintenance Free Backup Unit that protects the integrity of the cached data on Intel ^® Integrated RAID Modules by offloading the data stored in the RAM cache to NAND flash during a power loss event. And it eliminates the need for lithium ion (Li-ion) batteries traditionally used to protect DRAM cache memory on RAID controllers.

SAS/SATA Standards and Communication Protocols

The 12Gb/s Intel ^® RAID Controllers support the ANSI Serial Attached SCSI standard, version 3.0. 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 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

General Description

The 12Gb/s Intel ^® RAID Controllers bring 12.0 Gb/s Serial Attached SCSI and SATA III performance to host adapter, workstation, and server designs. The 12Gb/s Intel ^® RAID Controllers are based on the LSISAS3108 RAID On-a-Chip (ROC) device or the LSISAS3008 SAS chip.

The controllers support internal storage devices and external storage devices, which allow you to use a system that supports enterprise-class SAS drives and desktop-class SATA III drives. Each 12Gb/s Intel ^® RAID Controller can connect to drives directly and can use expanders to connect to additional drives. Simplified cabling between devices is an additional benefit.

These devices are compliant with the Fusion-MPT ^TM architecture and provides a PCIe x8 interface. Each port on the 12Gb/s Intel ^® RAID Controllers supports SAS devices, SATA devices, or both, using SSP, SMP, STP, and SATA. The SSP protocol enables the 12Gb/s Intel ^® RAID Controllers to communicate with other SAS devices. The SATA protocol enables the 12Gb/s Intel ^® RAID Controllers to communicate with SATA devices.

12Gb/s Intel ^® RAID Controller Detailed Descriptions

The 12Gb/s Intel ^® RAID Controllers are described in detail in the following subsections.

Intel ^® RAID Controller RS3WC080

The Intel ^® RAID Controller RS3WC080 is a PCIe 3.0 Low-Profile SAS Controller that controls eight internal SAS/SATA ports through two SFF-8643 mini-SAS HD-4i internal connectors.

Intel ^® RAID Controller RS3DC040 and RS3DC080

• The Intel ^ RAID Controller RS3DC040 is a PCIe 3.0 Low-Profile SAS Controller that controls four internal SAS/SATA ports through one SFF-8643 mini-SAS HD-4i internal connector.
• The Intel ^ RAID Controller RS3DC080 is a PCIe 3.0 Low-Profile SAS Controller that controls eight internal SAS/SATA ports through two SFF-8643 mini-SAS HD-4i internal connectors.

Configuration Scenarios

You can use the 12Gb/s Intel ^® RAID Controllers in three main scenarios:

• Low-end internal SATA configuration: In this configuration, use the RAID controller as a high-end 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.
• High-end external SAS/SATA configuration: This configuration is for external connectivity using SATA II drives, SATA III drives, SAS drives, or combinations of SATA and SAS drives. External enclosure management is supported through in-band, SCSI-enclosed storage. The configuration must support STP and SMP.

The following figure shows a direct-connect configuration. The Inter-IC (I²C) interface communicates with peripherals. The external memory bus provides a 32-bit memory bus, parity checking, and chip select signals for pipelined synchronous burst static random access memory (PSBRAM), nonvolatile static random access memory (NVSRAM), and Flash ROM.

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.

The 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.

PCI Express Architecture

PCIe is a local bus system designed to increase data transfers without slowing down the central processing unit (CPU). You can install the 12Gb/s Intel ^® RAID Controllers in PCIe computer systems with a standard bracket type. With these controllers in your system, you can connect SAS devices and SATA devices over the bus.

Note: Some PCIe slots support PCIe graphics cards only; RAID controllers installed in these PCIe slots do not function.

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.

Operating System Support

The 12Gb/s Intel ^® RAID Controllers support the following operating systems:

• Microsoft Windows 2003* R2 SP2, Windows Vista* SP2, Windows 7* Client SP1, Windows 8*, Windows 2008* SP2, Windows 2008* R2 SP1, and Window Server 2012*

  • They provide a serial, point-to-point, enterprise-level storage interface.
• They simplify cabling between devices.
• They provide a scalable interface that supports up to 240 devices through the use of expanders.

Note: The number of devices varies depending on the Intel ^® RAID Controller product. Check the Intel website, http://www.intel.com, for specific details about your product.

• They support wide ports that consist of two, three, or four PHYs within a single quad port.
• They support narrow ports consisting of a single PHY.
• They transfer data by using SCSI information units.

SAS Array Limitations

This section describes the array limitations of the 12Gb/s Intel ^® RAID Controllers. These limitations include the number of drives supported per controller, the maximum number of drives per controller, and the maximum number of virtual drives allowed per controller.

The following table lists the array limitations for the 12Gb/s Intel ^® RAID Controllers.

Table 2. 12Gb/s Intel ^® RAID Controller Array Limitations

Specification	Intel® RAID Controller RS3WC080	Intel® RAID Controller RS3DC040/RS3DC080
Maximum virtual drives per controller 64 64
Maximum drive groups per controller 128 128
Maximum virtual drives per drive group 16 16
Maximum drives per drive group 32 32
Maximum drives per controller 240 240
Maximum hot spares per controller 240 240
Maximum spans per virtual drive	8	8
Maximum enclosures per portA	10 10
Number of port connectors	5	5

A. The number assumes one storage enclosure processor (SEP) per enclosure.

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 Intel ^® RAID Controller RS3DC0x0, the maximum number of drive groups per controller is 240, 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.

SATA III Features

The following list describes the SATA III features of the RAID controllers:

• They support SATA III data transfers of 6Gb/s for LSISAS3108-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 fail-over configuration) through an expander.

• 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.

Drive 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.

1. Reconnect the power cords to the system.

2. Turn on the power to the system.

The controller then detects the RAID configuration from the configuration data on the drives.

Drive 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.

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.

1. Turn off power to the server and all drives, enclosures, and system components. Disconnect the power cords from the systems.

2. Open the host system by following the instructions in the host system technical documentation.

3. 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.

1. Remove the drives from the first system, and insert them into the drive bays on the second system.

2. Connect the SAS cables to the drives in the second system.

3. Determine the SAS target requirements.

4. 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.

1. Reconnect the power cords to the system.

2. Turn on the power to the system.

The controller detects the RAID configuration from the configuration data on the drives.

c. Close the cabinet of the host system.

1. Reconnect the power cords to the system.

2. Turn on the power to the system.

Make sure that the power is turned on to any external drives before the power is turned on to the host computer. If the computer is powered up before these devices, the devices might not be recognized.

Detailed Installation

This section provides detailed instructions on how to install your 12Gb/s Intel ^® RAID Controller.

The figure in this section shows the installation of the Intel ^® RAID Controller RS3DC080 in a PCIe slot. You can install the Intel ^® RAID Controller RS3WC080 and the Intel ^® RAID Controller RS3DC040 in the same way.

1. Unpack the 12Gb/s Intel ^ RAID Controller.

Unpack and remove your RAID controller. Inspect it for damage. If it appears damaged, contact your Intel Customer and Technical Support representative.

1. 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.

1. 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, 12Gb/s Intel ^® RAID Controller Characteristics, for diagrams of the 12Gb/s Intel ^® RAID Controllers that show their jumpers and connectors.

1. Install the RAID controller.

Select a PCIe slot, and align the controller's PCIe bus connector to the slot, as shown in the following figure. 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.

Note: 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 RAID 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 a RAID controller is installed in one of these slots, the RAID controller will not

function. Refer to the guide for your motherboard for information about the PCIe slot.

Figure 3. Example of the Intel® RAID Controller RS3DC080 Installation in a PCIe Slot

1. 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 pre-installation configuration requirements.

1. Connect the RAID controller to the devices.

Use SAS cables to connect SAS devices, SATA devices, or both to the 12Gb/s Intel® RAID Controller. See SAS Device Cables and Connectors for SAS cable and connector information. See Connecting a RAID Controller with Internal Port Connectors by Cable to Internal 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.

1. 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 12Gb/s Intel ^® 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.

1. Run the RAID BIOS Console Configuration Utility.

Run the RAID BIOS Console Configuration Utility to configure the drive groups and the virtual drives. When the message Press Ctrl+G for RAID BIOS Console appears on the screen, immediately press Ctrl+G to run the utility.

1. Install the operating system driver.

The 12Gb/s Intel ^® RAID Controllers can operate under various operating systems. To operate under these operating systems, you must install the software drivers.

After Installing the RAID Controller

After you install the 12Gb/s Intel ^® RAID Controller, you must configure the controller and install the operating system driver. The Intel ^® RAID Software User Guide instructs you on the configuration options and how to set them on your 12Gb/s Intel ^® RAID Controller. The Intel SAS Device Driver Installation User Guide provides detailed installation instructions for operating system drivers.

SAS Device Cables and Connectors

This section describes the cables and the connectors used on the 12Gb/s Intel ^® RAID Controllers and provides step-by-step instructions for connecting SAS drives, SATA drives, or both to the 12Gb/s Intel ^® RAID Controller.

B

BIOS Acronym for Basic Input/Output System. Software that provides basic read/write capability. Usually kept as firmware (ROM-based).

The system BIOS on the motherboard of a computer boots and controls the system. The BIOS on your host adapter acts as an extension of the system BIOS.

C

configuration Refers to the way a computer is set up, the combined hardware components (computer, monitor, keyboard, and peripheral devices) that make up a computer system, or the software settings that allow the hardware components to communicate with each other.

D

device driver A program that permits a microprocessor (through the operating system) to direct the operation of a peripheral device.

domain validation A software procedure in which a host queries a device to determine its ability to communicate at the negotiated data rate.

drive group A group of physical drives that combines the storage space on the drives into a single segment of storage space. A hot spare drive does not actively participate in a drive group.

E

EEPROM Acronym for Electronically Erasable Programmable Read-Only Memory. It is a memory chip that typically stores configuration information, as it provides stable storage for long periods without electricity and can be reprogrammed. See NVRAM.

external SAS device A SAS device installed outside the computer cabinet. These devices are connected using specific types of shielded cables.

F

Fusion-MPT architecture An acronym for Fusion-Message Passing Technology architecture. Fusion-MPT consists of several main elements: Fusion-MPT firmware, the Fibre Channel and SCSI hardware, and the operating system-level drivers that support these architectures. Fusion-MPT architecture offers a single binary, operating system driver that supports both Fibre Channel and SCSI devices.

H

host The computer system in which a RAID controller is installed. It uses the RAID controller to transfer information to and from devices attached to the SCSI bus.

host adapter board A circuit board or integrated circuit that provides a device connection to the computer system.

hot spare

An idle, powered on, standby drive that is ready for immediate use in case of drive failure. A hot spare does not contain any user data. A hot spare can be dedicated to a single redundant array or it can be part of the global hot-spare pool for all arrays managed by the controller.

When a drive fails, the controller firmware automatically replaces and rebuilds the data from the failed drive to the hot spare. Data can be rebuilt only from virtual drives with redundancy (RAID levels 1, 5, 6, 10, 50, and 60; not RAID level 0), and the hot spare must have sufficient capacity.

internal SAS device

A SAS device installed inside the computer cabinet. These devices are connected by using a shielded cable.

M

main memory The part of computer memory that is directly accessible by the CPU (usually synonymous with RAM).

N

NVRAM Acronym for nonvolatile random access memory. An EEPROM (electronically erasable read-only memory) chip that stores configuration information. See EEPROM.

P

PCI Acronym for peripheral component interconnect. A high-performance, local bus specification that allows the connection of devices directly to computer memory. The PCI Local Bus allows transparent upgrades from 32-bit data path at 33 MHz to 64-bit data path at 33 MHz, and from 32-bit data path at 66 MHz to 64-bit data path at 66 MHz.

PCI Express Acronym for peripheral component interconnect Express. A high-performance, local bus specification that allows the connection of devices directly to computer memory. PCI Express is a two-way, serial connection that transfers data on two pairs of point-to-point data lines. PCI Express goes beyond the PCI specification in that it is intended as a unifying I/O architecture for various systems: desktops, workstations, mobile, server, communications, and embedded devices.

peripheral devices A piece of hardware (such as a video monitor, drive, printer, or CD-ROM) used with a computer and under the control of the computer. SCSI peripherals are controlled through an Intel ^® RAID Controller (host adapter).

PHY The interface required to transmit and receive data packets transferred across the serial bus.

Each PHY can form one side of the physical link in a connection with a PHY on a different SATA device. The physical link contains four wires that form two differential signal pairs. One differential pair transmits signals, while the other differential pair receives signals. Both differential pairs operate simultaneously and allow concurrent data transmission in both the receive and the transmit directions.

RAID Acronym for Redundant Array of Independent Disks (originally Redundant Array of Inexpensive Disks). An array (group) of multiple independent drives managed together to yield higher reliability, performance, or both exceeding that of a single drive. The RAID array appears to the controller as a single storage unit. I/O is expedited because several drives can be accessed simultaneously. Redundant RAID levels (RAID levels 1, 5, 6, 10, 50, and 60) provide data protection.

RAID levels A set of techniques applied to drive groups to deliver higher data availability, performance characteristics, or both to host environments. Each virtual drive must have a RAID level assigned to it.

s

SAS Acronym for Serial Attached SCSI. A serial, point-to-point, enterprise-level device interface that leverages the proven SCSI protocol set. The SAS interface provides improved performance, simplified cabling, smaller connections, 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. The SAS controllers support the ANSI Serial Attached SCSI Standard, Version 2.0. In addition, the controller supports the Serial ATA III (SATA III) protocol defined by the Serial ATA Specification, Version 3.0. Supporting both the SAS interface and the SATA III interface, the SAS controller is a versatile controller that provides the backbone of both server and high-end workstation environments. Each port on the SAS RAID controller supports SAS devices, SATA devices, or both.

SAS device Any device that conforms to the SAS standard and is attached to the SAS bus by a SAS cable. This includes SAS RAID controllers (host adapters) and SAS peripherals.

SATA Acronym for Serial Advanced Technology Attachment. A physical storage interface standard, SATA is a serial link that provides point-to-point connections between devices. The thinner serial cables allow for better airflow within the system and permit smaller chassis designs.

SMP Acronym for Serial Management Protocol. SMP communicates topology management information directly with an attached SAS expander device. Each PHY on the controller can function as an SMP initiator.

SSP Acronym for Serial SCSI Protocol. SSP enables communication with other SAS devices. Each PHY on the SAS controller can function as an SSP initiator or an SSP target.

STP Acronym for Serial Tunneling Protocol. STP enables communication with a SATA device through an attached expander. Each PHY on the SAS controller can function as an STP initiator.

strip The portion of a stripe that resides on a single drive.

stripe size The total drive space consumed by a stripe not including a parity drive. For example, if a stripe contains 64 KB of drive space and has 16 KB of data residing on each drive, the stripe size is 64 KB and the strip size is 16 KB.

A larger stripe size produces improved read performance, especially if most of the reads are sequential. For mostly random reads, select a smaller stripe size.

striping Drive striping writes data across two or more drives. Each stripe spans two or more drives but consumes only a portion of each drive. Each drive, therefore, may have several stripes. The amount of space consumed by a stripe is the same on each drive that is included in the stripe. The portion of a stripe that resides on a single drive is a strip, also known as a stripe element. Striping by itself does not provide data redundancy; striping in combination with parity provides data redundancy.

strip size The drive space consumed by a strip. For example, if a stripe contains 64 KB of drive space and has 16 KB of data residing on each drive, the stripe size is 64 KB and the strip size is 16 KB. The stripe depth is four (four drives in the stripe). You can specify strip sizes of 8 KB, 16 KB, 32 KB, 64 KB, 128 KB, 256 KB, 512 KB, or 1 MB.
