HP Smart Array 642 Controller

The Smart Array 642 Controller (SA-642) is a 64-bit, 133-MHz PCI-X, dual channel, SCSI array controller for entry-level hardware-based fault tolerance. Utilizing both SCSI channels of the SA-642 allows you to configure up to 6 internal and 14 external hard drives to store up to 6 TB of storage.

The 64MB and 128MB BBWC (Battery Backed Write Cache) Enabler upgrade allows the SA-642 controller an option to add transportable BBWC for improved controller performance and increases the total controller memory, up to 192MB. The SA-642 also features complete data compatibility with previous generation's Smart Array controllers to ease data migration from server to server and for easy controller upgradeability.

Standard Features

The Smart Array Advantage HP's innovative design and integration work of the Smart Array family of products creates customer value that is unmatched in the industry. Use of Smart Array products across multiple applications results in a much lower Total Cost of Ownership (TCO) than any other server storage RAID product. The HP Smart Array family brings an unparalleled return on investment through:
Data Compatibility among all models of Smart Array controllers allows simple and easy upgrades any time needs for higher performance, capacity, and availability increase. Even successive generations of Smart Array controllers understand the data format of other Smart Array Controllers.
Consistent Configuration and Management Tools. All Smart Array products utilize a standard set of management and utility software. These tools minimize Total Cost of Ownership (TCO) by reducing training requirements and technical expertise necessary to install and maintain the HP server storage.
Universal Hard Drive form factor is for use across multiple HP servers, disk enclosures and storage systems. With compatibility across many enterprise platforms, you are free to deploy and re-deploy these drives to quickly deliver increased storage capacity, migrate data between systems, and easily manage spare drives.
Pre-Failure Warranty means HP Insight Manager not only reports when a drive is going to fail but allows replacement of failing drives prior to actual failure. For complete details, consult the HP Support Center or refer to your HP Server documentation.

Key Features
  • Compatibility with all Ultra320, Ultra3 and Ultra2 LVD family products. In addition, a seamless upgrade to next generation HP high performance and high capacity mainstream Ultra320 Smart Array controllers.
  • Recovery ROM protects against a ROM corruption.
  • Ultra320 SCSI technology delivers high performance and data bandwidth up to 320-MB/s bandwidth per channel.
  • Modular, easy-to-upgrade design lets you optimize performance as needed with the 64MB and 128MB BBWC Enabler, from 64-MB of memory for RAID and read cache to up to 128-MB of BBWC.
  • Mix-and-match LVD SCSI compatibility protects your investments and lets you deploy drives as needed.
  • Software consistency among all Smart Array family products: Array Configuration Utility, Insight Manager (CIM), Array Diagnostic Utility (ADU) and SmartStart.
  • 64-bit, 133-MHz PCI-X interface boosts bandwidth above 1B/s burst transfer rate over PCI-X bus.
  • 64-bit memory addressing supports servers with greater than 4 GB of memory.
  • 64-MB memory optimizes performance and data throughput.
    NOTE: 64 MB of DDR memory used for RAID and read cache.

Online Management Features
  • Online Capacity Expansion
  • Online RAID Level Migration
  • Online Stripe Size Migration
  • Online Spares (Global)
  • User Selectable Expand and Rebuild Priority

  • Dual Channel: Provides the ability to support up to 20 (6 internal, 14 external) drives or 6.0 TB

Key Features for 64MB BBWC (Battery-Backed Write Cache) Enabler

  • Battery-backed Cache protects cached data in the event of a power outage, server failure or controller failure.
  • 72 hours of battery charge protects the data for an entire weekend.
  • 3 years of battery life.
  • Modular, easy-to-upgrade design lets you optimize performance as needed with the 64MB BBWC Enabler, from 64-MB of memory for RAID and read cache to 128-MB of memory for RAID, read cache, and BBWC.

Key Features for 128-MB BBWC (Battery-Backed Write Cache) Enabler

The 128MB BBWC Enabler is a transportable 128MB battery module increasing the total memory of the controller to 192MB for RAID, read cache, and BBWC. The transportability of the battery memory module protects the write cache data from unexpected power loss, system board failure, or controller board failure. Data retained in the write cache will be protected for up to 72 hours, allowing time to restore power, or transport the module to a functioning system board or array controller. The modular design of the battery memory module is transportable between the Smart Array 641 and Smart Array 642 controllers.

128MB BBWC (Battery Backed Write Cache) Enabler allows the 642 controllers an option to add transportable BBWC for improved controller performance and increases the total controller memory to 192MB.

Data Compatibility

Data compatibility among all models of Smart Array Controllers means customers can instantly upgrade their Smart Array products to get to higher performance, capacity and availability. Unlike competitive products, successive generations of Smart Array products understand the data format of other Smart Array controllers, providing investment protection for your HP storage solution.


HP's High Performance Architecture sets new boundaries of industry performance expectations!

  • Ultra320 SCSI (320 MB/s bandwidth) per channel
  • High-performance 64-bit architecture
  • 64-bit, 133-MHz PCI-X bus (1033 MB/s bandwidth)


Given the internal server storage need for rapid capacity expansion, the SA-642 offers:

  • Dual SCSI channels support up to 20 (6 internal, 14 external) disk drives
  • Up to 6.0TB of storage per PCI slot


Provides increased server uptime by providing advanced storage functionality:

  • Online RAID Level Migration (between any RAID level)
  • Online Capacity Expansion
  • Logical Drive Capacity Extension
  • Global Online Spare
  • Pre-Failure Warranty

Fault Prevention

The following features offer detection of possible failures before they occur, allowing preventive action to be taken:

  • S.M.A.R.T.: Self Monitoring Analysis and Reporting Technology first developed at Compaq detects possible hard disk failure before it occurs, allowing replacement of the component before failure occurs.
  • Drive Parameter Tracking monitors drive operational parameters, predicting failure and notifying the administrator.
  • Dynamic Sector Repairing continually performs background surface scans on the hard disk drives during inactive periods and automatically remaps bad sectors, ensuring data integrity.
  • Smart Array Cache Tracking monitors integrity of controller cache, allowing pre-failure preventative maintenance.
  • Environment Tracking for External Storage System: Monitors fan speed and cabinet temperature of ProLiant Storage System and newer HP storage enclosures.

Fault Tolerance

Keeps data available and server running while a failed drive is being replaced; several fault tolerance configurations are supported including:

  • Distributed Data Guarding (RAID 5): This allocates parity data across multiple drives and allows simultaneous write operations. It is recommended for up to 14 hard drives.
  • Drive Mirroring (RAID 1, 1+0): This allocates half of the drive array to data and the other half to mirrored data, providing two copies of every file. It is a high-performance RAID.

Fault Recovery

Minimizes downtime, reconstructs data, and facilitates a quick recovery from drive failure

  • Recovery ROM: This new feature provides a unique redundancy feature that protects from a ROM image corruption. A new version of firmware can be flashed to the ROM while the controller maintains the last known working version of firmware. If the firmware becomes corrupt, the controller will revert back to the previous version of firmware and continue operating. This reduces the risk of flashing firmware to the controller.
  • On-Line Spares: Up to two spare drives can be installed prior to drive failure. If a failure occurs, recovery begins with an On-Line Spare and data is reconstructed automatically.
    NOTE: On-Line Spares can only be used with RAID level 1, 1+0, and 5.

Ease of Use

Consistency and Upgradeability make the Smart Array family unique in the industry:

  • GUI based configuration, management and diagnostic software tools
  • Common data format between generations of products
  • Data migration between servers and external storage enclosures
