Controller Features
The Compaq Integrated Smart Array Controller is a dual-channel, 32-bit PCI controller supporting RAID technology. It also supports Wide Ultra2 SCSI technology for faster data transfer rates and is backward compatible with Wide-Ultra SCSI-3 devices. The Integrated Smart Array Controller supports SCSI drives either through the external Wide-SCSI connector or the internal 68-pin Wide-SCSI connector, with a maximum of two supported channels. Configuring the server to use two separate SCSI ports provides maximum internal and external drive support without having to commit the resources of an expansion slot.

Standard Features

Features of the Compaq Integrated Smart Array Controller include:
Support for RAID 0, RAID 1, RAID 0+1, and RAID 5
Support for Wide Ultra2 SCSI technology and an improved data transfer
rate maximum of 80 MB/s

NOTE: If higher performance, higher availability, or higher capacity is required, arrays can be moved from the Integrated Smart Array Controller to a higher performance array controller without requiring a backup-and-restore procedure, but only if relative drive order is maintained. If relative drive order is changed, or if no data backup exists, perform a full backup before moving any array to another controller.

Controller Interface

The Integrated Smart Array Controller server interface is a Peripheral Component Interface (PCI) bus. The PCI bus is a high-performance, 32-bit bus with multiplexed address and data lines. It includes a parity signal and provides a high-speed path (up to 132 MB/s) between the system board and the array controller. The Integrated Smart Array Controller is a PCI Bus Master device and conforms to PCI Local Bus Specification, Revision 2.2.
Figure 1-1. Integrated Smart Array Controller

Drive Array Technology

Drive array technology distributes data across a series of hard drives to unite physical drives into one or more logical drives. Distributing data allows concurrent access to data from multiple drives in the array, yielding faster input/output rates than nonarrayed drives. Each logical drive in the array may be set to a different fault-tolerant configuration and the Integrated Smart Array Controller manages the drive array independent of the host processor.
Controller Features 1-3
The Compaq Array Configuration Utility found on the SmartStart and Support Software CD guides you through configuring the hardware in the way that best suits your needs.
Refer to the material in Appendix B for general information about drive arrays. Chapter 4 contains information about configuring your Integrated Smart Array Controller with Option ROM Configuration for Arrays utility, and Chapter 6 contains information about configuring hard drives and drive arrays with the Compaq Array Configuration Utility.
1-4 Compaq Integrated Smart Array Controller User Guide

Fault Tolerance

Fault tolerance relies on various methods for protecting data from loss in the event of a hardware failure somewhere in the storage system. Each method has its advantages, so choosing one requires careful planning for your particular requirements.
Fault-tolerance methods supported by the Integrated Smart Array Controller and the Compaq Array Configuration Utility include:
Distributed data guarding (RAID 5)
Drive mirroring (RAID 1)
Drive striping and mirroring (RAID 0+1)
No-fault tolerance (RAID 0)
Further data protection achieved by assigning an online spare to any
RAID 0+1, RAID 1, or RAID 5 configuration
See Appendix B for more information on fault-tolerance methods supported by the Integrated Smart Array Controller. Chapter 6, “Compaq Array Configuration Utility,” contains information on configuring your system for each of the fault-tolerance methods.

Drive Movement

An array of drives can be moved from one system to another as long as the relative order of the drives is maintained. However, when the relative order of the drives is changed, or if a new array controller is installed or reconfigured, all data stored on the drives are affected. For more information, refer to Chapter 6 in this guide.

Read-Cache Memory

The Integrated Smart Array Controller has 16 MB of total memory, with 8 MB dedicated for read-ahead cache.

Expanding and Extending Capacity

The Compaq Array Configuration Utility (ACU) makes changing your storage configuration simple, even in fault-tolerant configurations, without requiring a data backup-and-restore cycle. If you are using Microsoft Windows NT or Novell NetWare operating systems with hot-plug drives, storage expansion or extension can be performed online without shutting down the server or exiting the operating system.
The Compaq ACU supports two important utilities:
Capacity expansion–Adding capacity and creating new drives
Capacity extension–Enlarging existing logical drives

Online RAID Level and Stripe Size Migration

The Array Configuration Utility allows you to reconfigure a currently configured logical drive for a new fault-tolerance (RAID) level or move an existing logical drive’s stripe size to a new stripe size online without disruption to system operations and without loss of data. For more information about online RAID level and stripe size migration, refer to Chapter 6.
Controller Features 1-5

Wide Ultra2 SCSI Technology

The Integrated Smart Array Controller uses Wide Ultra2 SCSI technology for improved performance. Wide Ultra2 SCSI technology uses Low Voltage Differential (LVD) signaling to allow maximum burst rates on the Ultra2 SCSI bus of up to 80 MB/s. LVD signaling doubles the maximum burst rates available in Wide-Ultra SCSI-3 devices.
NOTE: The maximum burst rate of up to 80 MB/s provided by Wide Ultra2 SCSI (LVD) signaling is achieved only when the array contains Wide Ultra2 SCSI (LVD) devices exclusively.

Wide Ultra2 SCSI Compatibility

The Integrated Smart Array Controller is compatible with your existing SCSI devices. Wide Ultra2 SCSI works with devices that respond at transfer rates of up to 80 MB/s. Connected peripherals are limited to response times no faster than the transfer rate of the slowest device in the array.
1-6 Compaq Integrated Smart Array Controller User Guide

Wide-Ultra SCSI-3 Compatibility

In addition to using Wide Ultra2 SCSI technology, the Integrated Smart Array Controller complies with ANSI SCSI-3 standards and can support 16-bit Wide-Ultra SCSI-3 devices.

Refer to Chapter 4, Option ROM Configuration for Arrays Utility, for detailed instructions on configuring the Integrated Smart Array Controller.
Chapter 3
Updating Firmware
The ROMs on all Compaq servers and most Compaq options can be updated easily by flashing the ROM. To flash a ROM, Compaq ROMPaq replaces the existing contents of the ROM with an updated version stored in a disk file. This method is a convenient way to distribute new firmware and to keep Compaq products up-to-date with the latest capabilities.
There are two ROMPaq utilities:
System ROMPaq
Update the system ROM in all Compaq servers supporting Flash ROM. Use System ROMPaq when you install a new Integrated Smart Array Controller in a Compaq server to be sure that the server utilizes the full range of capabilities available from the Integrated Smart Array Controller.
Options ROMPaq
Update the onboard ROM on all Compaq options supporting Flash ROM. Use Option ROMPaq when new versions of the Integrated Smart Array Controller firmware or SCSI drive firmware become available to take advantage of expanded capabilities.
IMPORTANT: Before you install the new Integrated Smart Array Controller in your server, update the system firmware by running the System ROMPaq utility. This process ensures that you have the latest ROM on your system.
Use the instructions in the following section to create diskettes with the latest version of System ROMPaq from the Compaq SmartStart and Support Software CD.
