The Smart Array 641 Controller (SA-641) is a 64-bit, 133-MHz PCI -X single SCSI channel PCI array controller for entry level hardware-based fault tolerance. Utilizing the internal SCSI channel of the SA-641 allows you to configure up to 6 internal hard drives to store up to 880.8 GB of storage.


The SA-641 provides high reliability and increased performance over the LC2 controller, thus providing excellent value and lowering the total server ownership cost. In addition, the SA-641 is data compatible with all Ultra 320, Wide Ultra3 and Wide Ultra2 drives, offering an unparalleled degree of investment protection. 


Designed and integrated with HP entry-level and workgroup ProLiant servers, this product provides worry-free data protection.


The Smart Array Controller can be upgraded with the 64-MB or 128-MB BBWC (Battery Backed Write Cache) Enabler allowing the Smart Array 641 Controller an option to add transportable BBWC for improved controller performance.

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


The 64MB BBWC Enabler is a transportable 64MB battery module increasing the total memory of the controller to 128MB 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.
64MB BBWC (Battery Backed Write Cache) Enabler allows the 641controllers an option to add transportable BBWC for improved controller performance and increases the total controller memory to 128MB.













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


The new 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 641controllers 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.













Performance



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



  • Wide Ultra320 SCSI (320 MB/s bandwidth) per channel

  • High-performance 64-bit architecture

  • 64-bit, 133-MHz PCI-X bus (1033 MB/s bandwidth)















Capacity



Given the internal server storage need for rapid capacity expansion, the SA-641 offers:



  • Single SCSI channel support up to 6 internal disk drives

  • Up to 880.8GB of storage per PCI slot















Availability



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 Upgradability 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
