This broad compatibility ensures that the P420i can be integrated into virtually any enterprise environment, providing a high-performance storage solution that supports diverse software ecosystems.

Smart Array P420i Cache and Performance Enhancement

Optional Cache Module

To further enhance the performance of the P420i, an optional cache module is available. The 1 GB of cache memory allows the controller to store frequently accessed data for faster retrieval. This results in a significant boost in performance, especially in high-demand environments where I/O operations are frequent. With the cache, the P420i can handle workloads more efficiently, reducing the strain on the underlying storage devices.

Improved Data Throughput

The integration of cache memory in the P420i helps reduce latency by temporarily storing data before it is written to disk. This is particularly beneficial for read-intensive applications, such as database management systems, where quick access to data is crucial. The cache serves as an intermediary between the storage drives and the system, ensuring faster processing times and improved overall system performance.

Battery-Backed Cache

For added reliability, the Smart Array P420i can be equipped with a battery-backed cache module. This ensures that any data in the cache is preserved in the event of a power failure, reducing the risk of data loss and maintaining system stability. This feature is particularly important in enterprise environments where data integrity is paramount.

Advanced Data Protection Features

The P420i is designed with robust data protection features to ensure that your data remains secure and intact. With support for various RAID levels, as well as advanced diagnostic tools, the controller offers comprehensive protection against data loss and hardware failures.

Self-Healing Technology

The P420i comes equipped with self-healing capabilities, which allow the controller to detect and correct errors automatically. This proactive approach to error management helps prevent data corruption and reduces the need for manual intervention. In case of drive failure, the P420i can automatically rebuild data on a replacement drive, minimizing downtime and maintaining system integrity.

Enhanced Data Redundancy

By supporting multiple RAID configurations, including RAID 5 and RAID 10, the P420i ensures that your data is always protected. These RAID levels provide redundancy, meaning that if one drive fails, the system can continue to operate without loss of data. In the case of a failure, the system can quickly rebuild the lost data from the remaining drives, ensuring minimal disruption to your operations.

Predictive Failure Analysis

The controller includes predictive failure analysis, which continuously monitors the health of the drives and warns administrators of potential failures before they occur. This gives your IT team the ability to replace failing drives before they cause data loss, helping to maintain business continuity and protect critical data.
