SCSI controller, and the Intel Integrated RAID software.

The Intel Server RAID Controller SMU22R Design Kit was created to allow OEM’s and

IHV’s to design and manufacture their own branded RAID controllers, based upon the hardware reference design and RAID software provided with the kit. The resulting RAID controller would be a specific implementation, validated with their own motherboard or system products, allowing the OEM or IHV to compliment their product line. Intel must perform some software customizations for each OEM or IHV so that their product will function properly.

RAID Features

OS Support

Intel Integrated RAID is designed to work with the following operating systems:

Windows NT* Server 4.0, Service Pack 4

Windows NT Server 4.0, Terminal Server Edition, Service Pack 4

Windows NT Server 4.0, Enterprise Edition, Service Pack 4

Novell NetWare* 4.2, Service Pack 6

Novell NetWare 5.0, Service Pack 2

SCO UnixWare* 7.1

Supported RAID levels

RAID 0 – The minimum number of drives supported is 1, maximum is 16.

RAID 1 – The minimum number of drives supported is 2, maximum is 16.

RAID 5 – The minimum number of drives supported is 3, maximum is 16.

RAID 10 – Minimum number of drives supported is 3, maximum is 16.

(

RAID 10 is a combination of RAID 0 and RAID1 and is not user selectable. It is a function of how the Intel Integrated RAID writes data on RAID 1 arrays with 3 or more disks configured.)

Hot Plug Drive Support

Remove and replace SCA disk drives while I/O activity is taking place on the same SCSI bus, provided that both the hard drive and backplane fully support hot-swap.

Online Array Expansion

The ability to add new drives to an existing array while the server is online. New space is immediately available for volume creation without requiring a reboot.

Online Volume Migration

Change a volume RAID level or stripe size while the server is online and the volume is inuse.

2.9

AutoDeclare Spare

When an existing array is in degraded state, adding a new disk that is of the same size or larger than the failed disk will automatically become a spare for the degraded array, and rebuild will then automatically commence. If the new disk is smaller than the failed disk, it will not be marked as a spare and the volume will remain degraded.

With a SAF-TE enclosure, a bus scan occurs automatically when the drive is inserted.

No manual intervention is required.

When an enclosure without SAF-TE support is used, a reboot or bus scan is required for the Auto Declare Spare feature to commence.

A new drive may have the same or different SCSI ID than the failed drive which it replaces.

Array Roaming

Array Roaming allows the user the ability to move a complete array to another system

(with drives in any SCSI ID slot) and still preserve RAID configuration and user data on that array. Intel Integrated RAID firmware versions do not have to be the same on both systems (firmware updates are backward compatible). The array being moved must be connected while the destination server is offline.

Background Initialization / Instant Availability

All necessary initializations take place in the background after submitting a RAID volume creation request. The new volumes are available immediately, protecting newly written data and creating parity data concurrently. Supported operating systems provide instant access to newly created arrays without requiring a system reboot. Volume initialization is not impacted by system reboots. Volume initialization will continue when the server is restarted.

Pass-Thru Disks

One or more SCSI disks attached to the RAID adapter may be presented to the operating system individually and not as part of a RAID volume.

2.10

Adjustable Rebuild Priority

Rebuilding a degraded volume incurs a load on the IOP, the secondary PCI bus, the volume itself, and the SCSI bus. Intel Integrated RAID software allows the user to select the rebuild priority (low, medium, high) to balance volume access and rebuild tasks appropriately. The priority determines the ratio of IOP cycles dedicated to the volume rebuild process versus the number of cycles available to receive requests from the OSM.

Like volume initialization, a system reboot does not require the rebuild process to restart from the beginning.

2.11

Global Hot-Spares

A global hot spare is a spare physical disk drive that has been marked as a hot spare and therefore is not passed through to the host OS and is not a member of an array. The hot spare automatically takes the place of a failed disk in a RAID 1, 5, or 10 volume. Multiple

Global Hot Spares are allowed. The user is warned when a selected hot-spare disk does not have at least the same capacity as the drives in the array.

3.0

Hardware Reference Design

3.1

PCI 2.2 Compliant

The Intel Server RAID Controller Reference Design is PCI 2.2 compliant. In addition, it is designed to function properly in PCI 2.1 compliant motherboards that provide a 3.3v power source to the PCI connector.

3.2

Intel i960 RM I/O Processor

The Intel Server RAID Controller Reference Design features the Intel i960 RM I/O processor. The core processor, PCI-to-PCI bridge, Memory Controller, and Application

Accelerator Unit are particularly useful in RAID applications. For more information on the Intel i960 RM processor, visit http://developer.intel.com/design/iio/index.htm.

3.2.1

i960 Core

The 80960JT core processor runs at 100Mhz on the i960 RM I/O processor internal 32-bit bus. Among other features, it contains a 128-bit register bus, 16Kbyte two-way instruction cache, 4Kbyte direct-mapped data cache, 1Kbyte zero wait state data RAM, and single clock execution of most instructions.

3.2.2

PCI-to-PCI Bridge Unit

The PCI-to-PCI bridge features fully independent PCI bus operation with independent clocks, dedicated data queues, 32-bit 33Mhz PCI bus support, and 64-bit Dual Address

Cycle addressing.

3.2.3

Memory Controller

The Memory Controller provides direct control of memory systems external to the i960

RM I/O processor, including SDRAM, ROM, and Flash. It features programmable chip selects, a wait state generator, ECC single-bit correction and double-bit error detection.

The memory controller operates at 66Mhz.

Server RAID Controller SMU22R

3.2.4

Application Accelerator Unit

The Application Accelerator Unit (AAU) provides low-latency, high-throughput data transfer between the AAU and the 80960 local memory. In addition to performing data transfers, the AAU can perform XOR calculations on up to eight 128-byte pieces of data in one clock cycle. XOR calculations are used in every RAID 5 write transaction, and on every read transaction from a degraded RAID 5 volume.

3.3

Other Adapter Card Components

In addition to the Intel i960 RM I/O processor, the Intel Server RAID Controller

Reference Design utilizes the following major components.

3.3.1

LSI Logic

SYM53C896 SCSI Controller

The SYM53C896 is a PCI Dual-Channel Ultra 2 SCSI controller. It supports two SCSI channels with up to 80 MB/sec data transfer rate. It supports Low Voltage Differential

(LVD), High Voltage Differential (HVD), and Single-Ended SCSI devices. It also features

40Mhz internal operation, JTAG boundary scan, and 5 general purpose I/O pins.

3.3.2

Intel Smart 3 FlashFile

Flash Memory

This 3.3v, 16Mbit flash memory chip is used to store the RAID firmware. This nonvolatile storage can be address by the host processor for firmware updates.

3.3.3

ECC SDRAM

The Intel Server RAID Controller Reference Design provides an interface for 16Mbytes up to 128Mbytes of 3.3v ECC SDRAM. It is connected directly to the memory controller interface bus of the IOP, and serves as storage for the executable code transferred from the flash. It also serves as cache during RAID transactions and has 3 cache modes. Cache mode selection takes immediate effect while the server is online. Single-bit ECC error correction is provided by the Memory Controller.

The Downstream Write-Through cache mode uses cache memory to buffer write data until written to disk. This does not allow a read from cache following a write. All read commands get data from disk to ensure data consistency. This is not a user selectable option, however it is enabled any time that a Write-Back cache mode has not been selected.

Sequential Write-Back Cache mode is selectable on a per volume basis and gives a successful write reply as soon as the write data is moved to the RAID controller cache.

The actual write to disk will occur some time later. Only data from disk writes that are determined to be sequential are cached.

Full Write-Back mode is selectable on a per volume basis and gives a successful write reply as soon as the write data is moved to the RAID controller cache. Data from all disk writes is cached.

Server RAID Controller SMU22R

3.3.4

Battery Backup

The battery circuit provides power to the SDRAM when power is removed from the system to prevent data loss due to a power loss or a system shutdown. The circuit uses a single Lithium-Ion battery, which can maintain power to the SDRAM for about 24 hours.

This feature ensures that any I/O data in cache (due to user selection of a write-back cache mode) during an unexpected power loss is maintained.

3.3.5

Diagnostic Features

The 80960 RM I/O processor JTAG signals are brought to a 16-pin connector. This connector is used to interface the card to a JTAG emulator for design or manufacturing debugging.

The Intel Server RAID Controller Reference Design provides two SCSI activity LED’s to indicate traffic on each of the two SCSI channels. Also, two additional LED’s are designed in that indicate the presence of 3.3v in the PCI slot where the adapter resides, and the status of the IOP after booting from reset mode.

Additionally, jumper pins are provided which allow the adapter to be booted with the IOP in reset mode, allowing host access to recover non-functional firmware.

4.0

Intel Integrated RAID Software Features

4.1

Storage Console

The Intel Integrated RAID Storage Console is an HTML interface to the RAID subsystem.

This is the primary tool for configuring multiple RAID volumes, monitoring volume status, managing disk drives, viewing enclosure, and all other configuration aspects of the

RAID subsystem. A CGI application interfaces with the Storage OSM and I

2

O Executive

Service on the operating system. A CGI interpreter and HTML browser are required.

Novell NetWare and SCO Unixware provide these applications. Windows NT 4.0 requires an add-on product for the CGI interpreter, such as Microsoft Internet Information Server.

HTML browser requirements for Windows NT 4.0 are Microsoft Internet Explorer* 4.0 or higher, or Netscape Navigator* 4.0 or higher.

4.1.1

Remote Management

Since Storage Console is an HTML-based application, remote connections to the server are supported. The host operating system or web service is responsible for ensuring that proper remote user credentials are met when connecting remotely. The OSM still provides local security as described under the security heading below.
