HPE Smart Array P840 4GB FBWC 726897-B21 Raid Storage Controller

Capacity

The HPE Smart Array P840 Raid Storage Controller comes equipped with an impressive 4GB FBWC (Flash-Backed Write Cache) capacity. This powerful feature is designed to enhance the overall performance and reliability of your storage system, making it an essential component for users who require high-speed data processing and protection.

Improved Performance

The 4GB FBWC capacity of the HPE Smart Array P840 Raid Storage Controller allows for efficient caching of frequently accessed data. By storing this data in the cache, the controller can quickly retrieve and deliver it to the requesting applications or operating system. This dramatically reduces latency and improves overall system performance, enabling users to handle demanding workloads with ease.

Accelerated Data Writes

One of the key benefits of the 4GB FBWC capacity is its ability to accelerate data writes. When data is written to the storage system, it is first stored in the cache memory before being written to the actual drives. This process eliminates the need for immediate disk access, resulting in faster write speeds and reduced latency. As a result, users can experience enhanced productivity and reduced waiting times when dealing with data-intensive tasks.

Data Protection

The Flash-Backed Write Cache feature ensures that data integrity is maintained even in the event of a power loss or system failure. The 4GB capacity allows for a significant amount of data to be temporarily stored in the cache before being written to the drives. In case of an unexpected power interruption, the controller can quickly and efficiently write the cached data back to the drives once power is restored, minimizing the risk of data loss or corruption.

Increased Reliability

With the 4GB FBWC capacity, users can also benefit from increased reliability. By using flash memory as a backup power source, the HPE Smart Array P840 Raid Storage Controller ensures that critical data is protected during power outages or system failures. This added layer of protection gives users peace of mind, knowing that their data is safe and secure at all times.

This scalability ensures that your storage solution can grow alongside your business needs, saving you from having to invest in additional controllers or infrastructure.

Redundancy and Fault Tolerance

Having 2 ports in the HPE Smart Array P840 Raid Storage Controller also provides redundancy and fault tolerance benefits. By connecting multiple drives to separate ports, users can create redundant setups such as RAID configurations. In the event of a drive failure or port malfunction, the controller can seamlessly switch to the alternative port, ensuring continuous access to critical data without any downtime. This fault tolerance feature enhances the reliability and availability of your storage system.

Improved I/O Performance

The 2 ports in the HPE Smart Array P840 Raid Storage Controller enable improved I/O (Input/Output) performance by allowing simultaneous data transfers between multiple drives. With more ports available, users can distribute I/O operations across different drives, reducing bottlenecks and enhancing overall storage performance. This is particularly beneficial for applications that require high I/O throughput, such as databases or virtualized environments.

Flexible Connectivity Options

The 2 ports offer flexible connectivity options, allowing users to connect a variety of devices and drives to their storage system. Whether you need to connect SAS (Serial Attached SCSI) or SATA (Serial ATA) drives, the HPE Smart Array P840 Raid Storage Controller's ports provide compatibility with both interfaces, ensuring that you can leverage your existing drives or choose the most suitable technology for your specific requirements. This flexibility allows users to customize their storage solution based on their needs and preferences.
