ServeRAID M5210 SAS/SATA Controller for IBM System x User’s Guide July 2014

Chapter 1: Overview

1.1 ServeRAID M5210 Controller Description

The ServeRAID M5210 SAS/SATA controller is a PCI-Express 3.0, half-size, half-height RAID controller based on the LSISAS3108 PCI Express-SAS/SATA I/O Processor chip.

The controller controls eight internal SAS/SATA ports through two SFF-8643 4i internal mini-SAS HD connectors. The c

ontroller integrates eight high-performance SAS/SATA PHYs and a PCI Express bus master DMA core. Each of the

eight PHYs is capable of 12.0 Gb/s SAS link rates and 6.0 Gb/s SATA III link rates.

The controller brings 12.0 Gb/s SAS and 6.0 Gb/s SATA performance to host controller, workstation, and server designs.

he controller supports internal storage devices, which allows you to use a system that supports enterprise-class SAS

T drives, and desktop-class SATA drives. The controller can connect to drives directly. Simplified cabling between devices is an additional benefit.

ServeRAID M5210 Controller Description

Chapter 1: Overview

The LSISAS3108 ROC device increases syste supports data striping across multiple disks, which reduces disk access time because multiple disks simultaneously read or write data. In addition, the LSISAS3108 ROC device backs up data with either data mirroring or a parity block. Either backup method enables you to recover lost data in the event of a disk failure. You can select the data backup method that best suits your needs. A hardware RAID assist exclusive-OR (XOR) engine speeds parity generation and checking and reduces system-access times.

The controller supports the SAS protocol as described in the S III protocol defined by the Serial ATA Revision 3.0 Specification.

NOTE You cannot mix SAS drives and SATA drives within the same virtual drive.

Each port on the controller supports SAS devices and/or SATA devices using the following:

 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

ttached SAS expander device

 Serial Tunneling Protocol (STP), which enables communication with a SATA device through an attached expander

1.1.1 Controller Guidelines

before you install the controller, read the following guidelines:

1.2 Integrated MegaRAID Mode and MegaRAID mode

The ServeRAID M5210 controller can run in either integrated MegaRAID (iMR) mode natively or in MegaRAID (MR) mode with the addition of a transportable memory module.

Integrated MegaRAID Mode and MegaRAID mode

Chapter 1: Overview

iMR is a highly integrated, low-cost RAID solution made possibl

e by Fusion-MPT architecture. Integrated MegaRAID is a processor-based, hardware RAID solution designed for system environments requiring redundancy and high availability where a full-featured RAID implementation is not required or might be cost prohibitive.

The major advantage of iMR is that it provides RAID at the processo

r level, so it does not burden the CPU, which allows for more efficient operation. iMR mode is native to the ServeRAID M5210 controller and does not require a transportable memory module.

The major advantage of MR mode is that the it supports mor

e RAID levels than iMR mode. iMR mode supports RAID levels 0, 1, 5, 10, and 50 and supports 64k stripe size only. MR mode supports RAID levels 0, 1, 5, 6, 10, 50, and 60 and supports 64k to 1M stripe size.

NOTE iMR mode RAID 5 requires purchase of the Feature on Demand upgrade.

NOTE MR mode RAID 5/50 requires a transportable memory module (4 options).

NOTE MegaRAID RAID 6/60 requires a transportable memory module (4 options) and the Feature on Demand

upgrade.

See Section 1.2.1, “Supported RAID

Level Upgrades” for information about these upgrades.

See Section 1.2.2, “Summary of RAID Levels” for information about the supported RAID levels.

1.2.1 Supported RAID Level Upgrades

To use RAID levels 5, 6, 50, or 60 with this controller, you need to install a Feature on Demand upgrade and/or a transportable memory module, depending on the RAID level.

This controller supports iMR RAID levels 5 and 50 with the following installed Feature on Demand upgrade:

 ServeRAID M5200 Series Zero Cache/RAID 5 Upgrade for IBM System x

This controller supports MegaRAID RAID levels 5 and 50, with any of the following installed transportable memory modules:

 ServeRAID M5200 Series 1GB Cache/RAID 5 Upgrade for IBM System x  ServeRAID M5200 Series 1GB Flash/RAID 5 Upgrade for IBM System x  ServeRAID M5200 Series 2GB Flash/RAID 5 Upgrade for IBM System x  ServeRAID M5200 Series 4GB Flash/RAID 5 Upgrade for IBM System x

This controller supports MegaRAID RAID levels 6 and 60 with the ServeRAID M5200 Series RAID 6 Upgrade for IBM System x

1.2.2 Summary of RAID Levels

RAID levels describe a system for ensuring the availability and redundancy of data stored on large disk subsystems.

RAID 0 uses striping to provide high data throughput, especially for large files in an environment that does not require fault tolerance.

Chapter 1: Overview

Configuration Scenarios

RAID 1 uses mirroring so that data written to one drive is simultaneous

ly written to another drive. This is good for

small databases or other applications that require small capacity but complete data redundancy.

RAID 5 uses disk striping and parity data across all drives

(distributed parity) to provide high data throughput,

especially for small random access.

RAID 6 uses distributed parity, with two independent parity blocks per stripe

, and disk striping. A RAID 6 virtual drive can survive the loss of two drives without losing data. A RAID 6 drive group, which requires a minimum of three drives, is similar to a RAID 5 drive group. Blocks of data and parity information are written across all drives. The parity information is used to recover the data if one or two drives fail in the drive group.

RAID 10, a combination of RAID 0 and RAID 1, consists of striped data

across mirrored spans. A RAID 10 drive group is a spanned drive group that creates a striped set from a series of mirrored drives. RAID 10 allows a maximum of eight spans. You must use an even number of drives in each RAID virtual drive in the span. The RAID 1 virtual drives must have the same stripe size. RAID 10 provides high data throughput and complete data redundancy but uses a larger number of spans.

RAID 50, a combination of RAID 0 and RAID 5, uses distributed parit

y and disk striping. A RAID 50 drive group is a spanned drive group in which data is striped across multiple RAID 5 drive groups. RAID 50 works best with data that requires high reliability, high request rates, high data transfers, and medium-to-large capacity.

RAID 60, a combination of RAID 0 and RAID 6, uses distributed

parity, with two independent parity blocks per stripe in each RAID set, and disk striping. A RAID 60 virtual drive can survive the loss of two drives in each of the RAID 6 sets without losing data. It works best with data that requires high reliability, high request rates, high data transfers, and medium-to-large capacity.

NOTE Having virtual drives of different RAID levels, such as RAID 0 and RAID 5, in the same drive group is not allowed. For example, if an existing RAID 5 virtual drive is created out of partial space in an array, the next virtual drive in the array has to be RAID 5 only.

1.3 Configuration Scenarios

There are two main scenarios in which you can use this ServeRAID controller:

 Low-end, internal SATA configuration: In this configuration, use the ServeRAID controller as a high-end SATA

compatible controller that connects to several SATA disks. This type of configuration is mostly for low-end or entry level servers. Enclosure management is provided through out-of-band I2C bus. Side bands of both types of internal SAS connectors support the SFF-8485 and SFF-8448 (SGPIO) interface.

 Midrange, internal SAS configuration: This configuration is like the internal SATA configuration, but with high-end

disks. This type of configuration is more suitable for low-range to midrange servers.

The following figure shows a direct-connect configuration. The 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.

Inter-IC (I2C) interface communicates with peripherals.

Configuration Scenarios

1.3.1 Number of Physical Disks Supported

Your configuration planning for your ServeRAID controller depends in part on the number of physical disks that you want to use in a RAID array. The number of drives in an array determines the RAID levels that can be supported by this controller. Only one RAID level can be assigned to each virtual disk. Tabl e 1 shows the minimum number and the maximum number of drives required for each RAID level.

1.4 Benefits of the SAS Interface

SAS is a serial, point-to-point, enterprise-level device interface that leverages the proven SCSI protocol set. SAS combines the advantages of SATA, SCSI, and Fibre Channel, 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 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 ServeRAID M5210 SAS/SATA controller leverages a common electrical and physical connection interface that is compatible with Serial ATA technology. The SAS protocols and SATA 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.

1.4.1 PCI Express Architecture

Chapter 1: Overview

Benefits of the SAS Interface

PCI Express is a local bus system designed to increase data transfers without slowing down the central processing unit (CPU). You can install your ServeRAID M5210SAS/SATA controller in PCI Express computer systems with a standard bracket type. With this controller in your system, you can connect SCSI devices and SATA devices over the bus.

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.

1.4.2 Operating System Support

To check for the latest list of supported operating systems and to download the device drivers for those operating systems, see http://www.ibm.com/systems/support/.

The ServeRAID M5210 controller uses Fusion-MPT architecture for all major operating systems, thinner device drivers, and better performance.

Chapter 1: Overview

1.5.7 CacheCade

CacheCade is an advanced software option that is designed to accelerate the performance of hard disk drive (HDD) arrays with only an incremental investment in SSD technology. The MegaRAID CacheCade software utilizes SSDs as a dedicated pool of high-performance cache in front of HDDs to maximize I/O performance for transaction intensive applications. The key benefits of this software option include:

 Accelerated performance of existing HDD arrays with a small up-front investment  Read and Write caching of hot spot data for significant reduction in I/O latency  Optimized for real-world workloads of transaction-intensive applicaitons  Simple, intuitive management tools to assign and manage CacheCade SSD pool

These features help reduce latency bottlenecks for server-based HDD volumes. Applications are often constrained by the performance limitations of their existing HDDs. With this type of storage infrastructure already in place, a switch to a new array based purely on SSDs is cost prohibitive. Although SSDs are capable of many more transactions per second than HDDs, SSDs have a very high cost per gigabyte and are not suited for heavy, large file workloads. You can accelerate the performance of existing HDD arrays without making substantial investments in new hardware by deploying LSI MegaRAID CacheCade software, which leverages SSDs in front of HDD volumes to create high-capacity, high-performance controller cache pools.

1.5.8 Protection Information (T10-DIF)

The T10 Technical Committee of the INCITS standardized the basic requirements to implement a data protection model for end-to-end data protection. This model protects your data within a storage system from various sources of corruption that historically have gone undetected. Examples of corruption sources include hardware data path errors (such as FIFO overruns and underruns), firmware errors (such as arithmetic overflow or incorrect pointer usage), and external agents overwriting the data in memory.

- 10 -

Page 17

ServeRAID M5210 SAS/SATA Controller for IBM System x User’s Guide July 2014

A fundamental component of the T10 data protection model is the addition of 8 bytes of extra protection information transferred with each block of user data in the storage system, as shown in the following figure. Although not specifically named in the T10 standards, this collection of 8 bytes is commonly referred to as the DIF. The DIF contains three distinct values: a 2-byte logical block guard, a 2-byte logical block application tag, and a 4-byte logical block reference tag. The T10 specification defines four types of usage models of data protection: Type 0, Type 1, Type 2, and Type 3 (refer to the most current revision of INCITS T10/1799-D for further information)

Figure 3 T10 Data Integrity Field for MegaRAID Protection Information

1.5.9 Drive Roaming

Drive roaming occurs when the physical disks 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.

Benefits of the ServeRAID M5210 SAS/SATA Controller

Chapter 1: Overview

NOTE In a clustering environment, drive roaming is supported within the same channel only.

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 target ID.

NOTE If you move a drive that is being rebuilt, the rebuild operation restarts; it does not resume from where the rebuild operation stopped.

Follow these steps to use drive roaming:

1. Turn off the power to the server and all physical disks, enclosures, and system components. Disconnect the power

cords from the system.

2. Remove the server cover 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.

6. Make sure that the drives are inserted correctly.

7. Reinstall the server cover.

8. Reconnect the power cords to the system.

9. Turn on the power to the system.

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

Page 18

ServeRAID M5210 SAS/SATA Controller for IBM System x User’s Guide July 2014

1.5.10 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 Only whole virtual disks can be migrated automatically; partial virtual disks can be migrated manually.

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 Whe n you migrate drives, m ove only the d isks that mak e up the virt ual disk (n ot all of the physical di sks in an array), so that you do not have 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.

Benefits of the ServeRAID M5210 SAS/SATA Controller

Chapter 1: Overview

2. Turn off the power to the server and all physical disks, enclosures, and system components. Disconnect the power

cords from the systems.

3. Open the host system, following the instructions in the host system technical documentation.

4. Remove the SAS cable connectors from the internal drives that you want to migrate.

5. Make sure that pin 1 on the cable matches pin 1 on the connector.

6. Make sure that the SAS cables conform to all SAS specifications.

7. Remove the physical disks from the first system, and insert them into drive bays on the second system.

8. Connect the SAS cables to the physical disks in the second system.

9. Determine the SAS target requirements.

10. Perform a safety check.

11. Make sure that all of the cables are attached correctly.

12. Make sure that the RAID controller is installed correctly.

13. Reinstall the server cover.

14. Reconnect the power cords to the system.

15. Turn on the power to the system.

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

1.5.11 New Drives Attached to a ServeRAID Controller

In the Integrated RAID mode, when you insert a new drive with valid metadata into a ServeRAID system, the drive state of the new drive is either foreign or unconfigured bad.

The specific drive state depends on the Maintain PD Fail History setting, and whether the drive had been inserted in the system before. The Maintain PD Fail History setting, when enabled, maintains the history of all drive failures.

- 12 -

Page 19

ServeRAID M5210 SAS/SATA Controller for IBM System x User’s Guide July 2014

A foreign configuration is a storage configuration that already exists on the new drive that you install in the system. The configuration utilities allow you to import the foreign configuration to the controller, or to clear the configuration so you can create a new configuration using the new drive.

NOTE See the ServeRAID-M Software User’s Guide for the procedures used to import a foreign configuration or change a drive state from unconfigured bad to unconfigured good.

1.5.12 Automatic Rebuilds on New Drives

Automatic rebuilds occur when the drive slot status changes. For example, an automatic rebuild occurs when you insert a new drive or when you remove a drive and a hot spare replaces the removed drive.

1.5.13 System (JBOD) Drives

The iMR mode supports drives in pass-through mode, which are identified as "system" drives. These drives are also known as JBOD (Just a Bunch of Disks) drives. When a drive without valid metadata is inserted in a system, if the drive has a drive state of unconfigured good, it is identified as unconfigured good; otherwise, the drive is marked as a system drive.

System drives are exposed directly to the operating system. The host system can read data from and write data to the system drives; however, you cannot use system drives in a RAID configuration.

Chapter 1: Overview

Hardware Specifications

You can change system drives into unconfigured good drives (you can also change unconfigured good drives into system drives). When a system drive is changed to an unconfigured good drive, the unconfigured good drive state of the drive is maintained after reboot, drive removal, or drive insertion.

You can use system drives as bootable drives. iMR supports up to 63 system drives and up to 16 unconfigured good drives.

1.6 Hardware Specifications

2-pin Connector A connected LED will indicate that a write command is

pending by turning the LED on. This feature is used with the write-back feature.

2-pin Connector When shunted provides the ability to bypass loading the

Bootstrap configuration from external SBR EEPROM device and load the default system values within the ROC. This will allow the hardware to recover the blank or corrupted SBR device using Mega RAID software utilities.

Default mode of operation is to not have a shunt on this jumper and load the Bootstrap configuration from external SBR EEPROM device.

Allows a connection to a RAID upgrade key to allow additional RAID level capabilities.

3.2.4 Power Supply Requirements for the ServeRAID M5210 SAS/SATA Controller

All power is supplied to the controller through the PCI Express 3.3V rails and the 12V rail. Onboard switching regulator circuitry operating from the 3.3V rails and the 12V rail provide the necessary voltages. The following states determine the typical current consumption of the controller:

1. During a hard reset

2. During a disk stress test

3. While sitting idle at the DOS prompt

4. During a disk stress test and deeply discharged Supercap pack.

The supply voltages are 12V ± 8 percent (from PCI edge connector only) and 3.3V ± - 9 percent (from PCI edge connector only).

Tab le 6 Power Supply

PCI Edge Connector State1 State 2 State 3 State 4

3.3V Supply 0.540A 1.08 0.960A 1.08A

+12V Supply 0.780A 1.28A 1.06A 1.78A

3.3V Auxiliary Supply 0.010A 0.010A 0.010A 0.010A

Tabl e 6 lists the power supply for the controller for each of the three states at the different voltages.

3.2.5 Operating and Non-operating Conditions

The operating (thermal and atmospheric) conditions for the ServeRAID M5210 SAS/SATA controller are:

 Relative humidity range is 20 percent to 80 percent noncondensing  Airflow must be at least 200 linear feet per minute (LFPM) to avoid operating the Intel IOP333 processor above the

maximum ambient temperature

 Temperature range: +10 °C to +60 °C

The parameters for the non-operating (such as storage and transit) environment for the controller are:

 Relative humidity range is 5 percent to 90 percent noncondensing  Temperature range: -30 °C to +80 °C

3.2.6 Safety Characteristics

The ServeRAID M5210 SAS/SATA controller meets or exceeds the requirements of UL flammability rating 94 V0. Each bare board is also marked with the supplier name or trademark, type, and UL flammability rating. The board is installed in a PCI Express bus slot, so all voltages are lower than the SELV 42.4 V limit.
