High Performance
Offers superior Smart Array performance, optimized for your PCI-X based ProLiant server.
Compaq's new high-performance architecture sets new boundaries of industry performance expectations!
- Wide Ultra3 SCSI (160 MB/s bandwidth) per channel
- High-performance 64-bit architecture, featuring a super-scalar RISC processor
- Enhanced RAID engine
- Performance memory architecture providing tri-directional data flow for improved performance
- 64-bit, 133-MHz PCI-X bus (1066-MB/s bandwidth)
Modular Cache Design
Easy-to-upgrade through a unique modular design gives you the ability to double the on board battery-backed write cache capacity from the standard 128MB to an industry leading 256MB.
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 re-maps 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.
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/Striping (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.
- Data Striping (RAID 0): This allocates data across multiple drives to optimize performance. Highest performance RAID with no data protection.
Fault Recovery
Minimizes downtime, reconstructs data, and facilitates a quick recovery from drive failure.
- Recovery ROM: provides a unique redundancy feature that protects from a ROM failure. A new version of firmware can be flashed to the ROM while the controller maintains the last know 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 four 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.
- ECC-Protected Cache Memory: Removable, battery-backed cache memory protects data, up to four days, in the event of power failure, server hardware failure or controller failure. In addition, Compaq provides an exclusive design that includes redundant and replaceable batteries for greater cache protection.
- Chip Recovery featured on the 128-MB and 256-MB Cache modules, protect the cache memory from a single chip failure and multi-bit errors from any single memory chip.
