HP 655636-B21 Smart Array P721m/512MB FBWC 6GBPS 4-ports SAS Controller

Capacity: 512MB FBWC

Enhanced Performance and Reliability

The HP SAS Controller is equipped with a substantial capacity of 512MB Flash-Backed Write Cache (FBWC). This feature enhances the performance and reliability of the controller Smart Array P721m, making it an excellent choice for demanding server environments.

Improved Write Performance

The 512MB FBWC acts as a buffer between the server's host memory and the storage devices, allowing for faster write operations. When data is written to the controller, it is first stored in the FBWC. This enables the controller to acknowledge the write operation immediately to the host system, enhancing overall system performance.

Data Protection and Recovery

In the event of power loss or system failure, the FBWC ensures data integrity by temporarily storing the data in cache. The controller can then write this data to the storage devices once power is restored, preventing any potential data loss. This feature provides added protection and peace of mind to users, especially in critical applications where data reliability is paramount.

Reduced Latency

By utilizing the FBWC, the HP Smart Array P721m SAS Controller significantly reduces latency during write operations. This leads to improved response times for applications and ultimately enhances the overall user experience. Whether you are running intensive database workloads or handling high-transaction environments, this feature ensures optimal performance without compromising data integrity.

Seamless Integration

The 512MB FBWC seamlessly integrates with other advanced features of the HP Smart Array P721m SAS Controller. It works in conjunction with other technologies such as RAID levels, caching algorithms, and drive optimization techniques to provide a comprehensive storage solution. This integration ensures that users can leverage the full potential of their storage infrastructure while maintaining high levels of data protection and reliability.

The controller can quickly rebuild RAID arrays or restore data from backups, ensuring that your business operations can resume promptly without significant disruptions.

Number Of Ports: 4

Flexible Connectivity Options

The HP Smart Array P721m SAS Controller comes equipped with 4 ports, providing users with flexible connectivity options for their storage devices.

Increased Storage Capacity

With 4 ports, users can connect multiple storage devices to the controller, thereby increasing the overall storage capacity of their server. This is particularly beneficial for businesses with growing data storage needs or those running resource-intensive applications that demand large amounts of storage space.

Improved Data Transfer Bandwidth

Having 4 ports allows for improved data transfer bandwidth as it distributes the workload across multiple connections. This reduces the chances of congestion and ensures that data can flow smoothly between the controller and the connected storage devices. The result is faster data access and improved system performance.

Redundancy and Fault Tolerance

The 4 ports of the HP Smart Array P721m SAS Controller offer redundancy and fault tolerance capabilities. Users can configure their storage devices in various RAID configurations, such as RAID 1 or RAID 5, to ensure data redundancy and protection against drive failures. By distributing data across multiple drives, users can safeguard their data and minimize the risk of data loss.

Flexibility for Storage Expansion

The 4 ports provide flexibility for future storage expansion. As your storage needs grow, you can easily add additional drives or arrays without the need for a new controller. This scalability ensures that your storage infrastructure can adapt to changing business requirements without significant investments in new hardware.
