1 Overview

The LSI Nytro MegaRAID Application Acceleration Card is a combination of LSI proven MegaRAID controller coupled with built-in Flash modules to be used as data cache devices with the help of Nytro caching software. The Nytro MegaRAID card for direct-attached storage (DAS) is designed to accelerate applications with RAID performance from DAS combined with intelligent caching using Nytro Flash modules. The Nytro MegaRAID card increases the storage performance up to 30, but retains the current investment in DAS. Using intelligent caching algorithms to help identify application hot data, the frequently accessed data is stored and accessed from Flash enabling the lowest possible latency. The Nytro MegaRAID cards are available with either an internal connector or an external connector for DAS devices. The following figures illustrate the flow of data on an internal and an external Nytro MegaRAID card.

Overview Key Features and Benefits of the Nytro MegaRAID CardThe Nytro MegaRAID Acceleration Card provides accelerated performance and improved manageability to MegaRAID with its two embedded Nytro Flash modules. The Nytro MegaRAID Acceleration Card uses Nytro Flash memory in front of the connected hard disk drive (HDD) volumes to create high-capacity and high-performance acceleration cache pools.

The Nytro MegaRAID Acceleration Card is based on the LSISAS2208 RAID On-a-Chip (ROC). This device is compliant with the Fusion-MPT architecture and provides a PCI Express 8 interface.

The Nytro MegaRAID Acceleration Card provides enterprise class data protection and transparent performance acceleration to direct-attached SCSI storage volumes. The card provides reliability, high performance, and fault-tolerant drive subsystem management. Performance acceleration is powered by intelligent caching using the onboard Nytro Flash module.

NOTE You need to carefully assess any decision to mix SAS drives and SATA drives within the same virtual drive (VD). Although you can mix drives, this practice is strongly discouraged because the drives have different performance and reliability characteristics.

1.1 Key Features and Benefits of the Nytro MegaRAID Card

Automatic self-starting and self-configuring Supports Read and Write caching Transparent to applications, file systems, OSs, and device drivers Provides an economical solution for accelerating applications by storing frequently accessed data on

low-latency Nytro Flash modules, while maintaining existing SAS or SATA connected hard drives, to achieve a balance of performance and cost savings

RAID1 is enabled when the user enables the write-back mode of the cache On initial power up, the card auto configures as Nytro Cache Drive Group 0, RAID 1, Write Back configuration

RAID level support for hard disk drives RAID levels 0, 1, 5, and 6 RAID spans 10, 50, and 60

Internal or external drive bay support JBOD mode support Nytro Flash module helps protect cache in the event of power fail no battery required SuperCap kit (option) to protect DRAM content in the event of power failure Faster rebuilds will occur due to servicing most storage requests from Nytro Flash module Compatible with existing MSM management interfaces supported by Nytro MegaRAID LSI Corporation- 6 -


Overview Configuration Scenarios1.2 Configuration Scenarios

You can use the Nytro MegaRAID Acceleration Cards in the following scenarios:

Low-end, SATA configuration:In this configuration, use the RAID card as a high-end SATA, SATA II, or SATA III compatible card that directly-connects up to four drives or to an expander. This configuration is mostly for low-end or entry servers. Enclosure management is provided through an out-of-band I2C bus.

Midrange SAS configuration: This configuration is like a SATA configuration, but with high-end SAS drives. This configuration is more suitable for low-range to mid-range servers.

The following figure shows a direct-connect configuration. The Inter-IC (I2C) interface communicates with peripherals. The external memory bus provides an 8-bit and 16-bit Flash read-only memory (ROM) and an 8-bit nonvolatile static random access memory (NVSRAM) data interface. The card can connect to a drive bay that uses an expander.

4.4 Creating a RAID 1 Virtual Drive with WebBIOS Configuration Utility

These steps describe how to create the virtual drive used for an OS. You can add other virtual drives to the running OS after the OS has been installed. The Nytro MegaRAID pre-boot BIOS utility (WebBIOS) that creates the virtual disk for the OS is accessible during the power-on self-test (POST) part of boot-up.

Refer to the Nytro MegaRAID SAS Software Users Guide, Chapter 8, for more information about the WebBIOS configuration utility (CU).

The following procedure describes the creation of a RAID 1 array. You can use other RAID levels, and the steps are the same except when selecting the RAID level. In RAID 1, the RAID controller duplicates all data from one drive to a second drive. RAID 1 provides complete data redundancy, but at the cost of doubling the required data storage capacity. It is appropriate for small databases or any other environment that requires fault tolerance but small capacity. Follow these steps to create the virtual disk in WebBIOS:

1. When the host computer is booting, hold down the Ctrl key and press the H key when the following text appears on the window:

6 Getting Started with the Nytro MegaRAID Card

6.1 Auto Configuration

NOTE The Auto Configuration method, RAID 1 is created with Write Back write policy option only by using the Nytro Flash module. The Default or Auto Configuration is created on system initialization by firmware using the Nytro Flash modules present on the Nytro MegaRAID controller.

The Default or Auto Configuration is created on system initialization by firmware using the Flash memory modules present on the Nytro MegaRAID controller.

Any modification made by you is treated as a change in the configuration, and the configuration is changed from Default or Auto Configuration to Manual configuration. If you modify the Default configuration, the new Manual configuration data is stored in NVRAM, and you cannot revert to Auto or Default configuration. To revert to Auto or Default configuration, you must select the factory default settings at the controller level. When the Auto or Default configuration is modified, firmware generates an event to notify the administrating application.

Based on the type of the RAID level and over provisioning, the size of the Nytro cache varies. Nytro MegaRAID software supports only RAID 0, RAID 1, and RAID 1-EC levels for Flash-based cache volume based

on the Nytro MegaRAID Firmware Configuration parameters. If for some reason, the Auto or Default configuration fails, it is switched to the Manual configuration.

You cannot create a cache volume from a combination of Flash memory modules and external SSD drives, however if there are external SSD connected, they are treated as normal SATA physical drives.

Operations, such as spare commission, rebuild, consistency check, initialization, and copy back are not supported on cache volume. Multiple volumes can be created using the Flash drives. Using either RAID 0 or RAID 1 level.

By default, auto configuration creates only one Nytro cache volume. You cannot change it unless you delete and create a new Nytro cache volume manually.

You can apply the factory default settings using the WebBIOS, MegaCLI, or PrebootCLI (but not through MSM).

These are the typical operations performed:

Clear the configuration. Create configuration.

Create VD. Create Nytro Cache.

For more information about using Nytro MegaRAID on WebBIOS, refer to Chapter 7, WebBIOS Configuration Utility.

For more information about using Nytro MegaRAID on MegaCLI, refer to Chapter 9, MegaRAID Command Tool.

Using the Nytro Cache Drive Configuring File System Hinting6.4 Configuring File System Hinting

File system hinting establishes a handshaking protocol with Nytro MegaRAID firmware to maintain file system blocks in Nytro Cache drive group as hot data; this helps reduce the latency when accessing frequently accessed data.

Perform these steps to enable file system hinting:

1. Install the File System Hinting supported MegaRAID driver RPM supplied with the Nytro MegaRAID package.

2. Install the nytroHinting RPM supplied with the Nytro MegaRAID package.

3. Create a Nytro Cache VD.

4. Create a source drive for which you want to enable File System Hinting.

5. Associate the source VD with Nytro Cache VD.

6. Enable File System Hinting on the source VD created (step 4 and step 5) by using the MegaCLI and StorCLI utilities.

NOTE If your root partition or boot is on a SAS drive which is being

discovered by the Nytro MegaRAID driver, you must use the driver update disk supplied in the Nytro MegaRAID package to update your Nytro MegaRAID driver in order to support File System Hinting.

If you have an existing Nytro MegaRAID driver installed on the system, you must upgrade the existing Nytro MegaRAID driver with the Nytro MegaRAID driver supplied with Nytro MegaRAID package to support File System Hinting.

Glossary Glossary

BBIOS 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.

CCache Fast memory that holds recently accessed data. Use of cache memory speeds subsequent access to the same

data. When data is read from or written to main memory, a copy is also saved in cache memory with the associated main memory address. The cache memory software monitors the addresses of subsequent reads to see if the required data is already stored in cache memory. If it is already in cache memory (a cache hit), it is read from cache memory immediately and the main memory read is aborted (or not started). If the data is not cached (a cache miss), it is fetched from main memory and saved in cache memory.

Caching The process of using a high speed memory buffer to speed up a computer systems overall read/write performance. The cache can be accessed at a higher speed than a drive subsystem. To improve read performance, the cache usually contains the most recently accessed data, as well as data from adjacent drive sectors. To improve write performance, the cache can temporarily store data in accordance with its write back policies.

Capacity A property that indicates the amount of storage space on a drive or virtual drive.

Ddevice driver A program that allows a microprocessor (through the operating system) to direct the operation of a

peripheral device.

drive group A drive group is a group of physical drives. These drives are managed in partitions known as virtual drives. A group of drives attached to a Nytro MegaRAID controller on which one or more virtual drives can be created. All virtual drives in the drive group use all of the drives in the drive group.

Eelastic cache Elastic cache is host write-only mirroring (HWOM). The host write is cached with RAID 1 protection on the

cache device. Host reads are not mirrored at the cache level.

external SAS device

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

FFlash Nytro Flash module that is 100x to 1000x faster than hard drives yet provides non-volatility. Flash memory

does not have the mechanical limitations and latencies of hard drives, so a Nytro Flash module is attractive when considering speed, noise, power consumption, and reliability.

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.

HHDD Hard disk drive

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.

HWOM Host Write-Only MirroringLSI Corporation- 40 -


Glossary IInitialization The process of writing zeros to the data fields of a virtual drive and, in fault-tolerant RAID levels, generating

the corresponding parity to put the virtual drive in a Ready state. Initialization erases all previous data on the drives. Drive groups work without initializing, but they can fail a consistency check because the parity fields have not been generated.

Internal Drive Bay

A bay internal the case and usually used for hard disk drives that do not require any access by the user.

internal SAS device

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

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

Mirroring The process of providing complete data redundancy with two drives by maintaining an exact copy of one drives data on the second drive. If one drive fails, the contents of the other drive can be used to maintain the integrity of the system and to rebuild the failed drive.

MSM MegaRAID Storage Manager software

NNytro Cache This term refers to the on-board Flash module used for user data cache, called Nytro Flash module.

PPCI Express

(PCIe)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 a SAS MegaRAID SAS RAID controller (host adapter).

PSBRAM Pipelined synchronous burst static random access memory

RRAID 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.

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

RAID 1 Uses mirroring so that data written to one drive is simultaneously written to another drive. RAID 1 is good for small databases or other applications that require small capacity but complete data redundancy.

RAID 1 EC RAID 1 with elastic cache (EC). Elastic cache is host write-only mirroring (HWOM). The host write is cached with RAID 1 protection on the cache device but host read requests. Host reads are not mirrored at the cache level.

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 any 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. LSI Corporation- 41 -


Glossary 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 8 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 parity 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.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.

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. RAID 60 works best with data that requires high reliability, high request rates, high data transfers, and medium-to-large capacity.NOTE The MegaSR controller supports the standard RAID levelsRAID 0, RAID 1, RAID 5, and RAID 10. The MegaSR controller comes in two variants, SCU and AHCI, both supporting a maximum of eight physical drives. A maximum of eight virtual drives can be created (using RAID 0, RAID 1, RAID 5, and RAID 10 only) and controlled by the MegaSR controller. One virtual drive can be created on an array (a maximum of eight if no other virtual drives are already created on the MegaSR controller), or you can create eight arrays with one virtual drive each. However, on RAID10, you can create only one virtual drive on a particular array.

ROC RAID On-a-Chip

SSAS 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.

SuperCap SuperCap has reference to a module containing many capacitors. Sometimes called, SuperCap, Super Capacitors, and Ultra Capacitors. Also called RAID Cache Protector and RAID CaseVault.

VVD Virtual Drive

A storage unit created by a Nytro MegaRAID controller from one or more drives. Although a virtual drive can be created from several drives, it is seen by the operating system as a single drive. Depending on the RAID level used, the virtual drive can retain redundant data in case of a drive failure.

WWrite-back In Write-Back Caching mode, the controller sends a data transfer completion signal to the host when the

controller cache has received all of the data in a drive write transaction. Data is written to the drive subsystem in accordance with policies set up by the controller.These policies include the amount of dirty/clean cache lines, the number of cache lines available, and elapsed time from the last cache flush.

Write-through In Write-Through Caching mode, the controller sends a data transfer completion signal to the host when the drive subsystem has received all of the data and has completed the write transaction to the drive.LSI Corporation- 42 -
