HPE Smart Array P840AR 12GB SAS Controller 2GB FBWC 843199-B21

Interface: SAS

The HPE Smart Array P840AR Internal SAS Controller offers a powerful and reliable interface for connecting storage devices to your server system. With its SAS (Serial Attached SCSI) interface, this controller provides users with numerous benefits and advantages that enhance their overall computing experience.

High-Speed Data Transfer

One of the key advantages of the SAS interface is its ability to support high-speed data transfer rates. With a data transfer rate of up to 12GB, the HPE Smart Array P840AR allows for lightning-fast data transmission between the controller and attached storage devices. This ensures that users can access and retrieve their data quickly and efficiently, improving overall system performance.

Improved Storage Scalability

The SAS interface also offers improved storage scalability, allowing users to easily expand their storage capacity as their needs grow. With the ability to connect multiple storage devices, such as hard drives or solid-state drives, users can easily add or remove drives without disrupting their system's operation. This flexibility is especially beneficial for businesses or organizations that require large amounts of storage space and need the ability to scale up their storage resources as necessary.

Enhanced Data Protection

In addition to its high-speed data transfer and storage scalability, the SAS interface also provides enhanced data protection features. The HPE Smart Array P840AR offers advanced RAID (Redundant Array of Independent Disks) capabilities, allowing users to configure their storage devices in various RAID configurations for improved data redundancy and fault tolerance. This ensures that in the event of a drive failure, users can still access their data without any loss or downtime.

Ports: 2

The HPE Smart Array P840AR Internal SAS Controller features two ports, providing users with added flexibility and connectivity options.

Increased Device Support

With two ports, users can connect a wide range of storage devices to the controller, including hard drives, solid-state drives, and tape drives. This increased device support allows for greater versatility and compatibility with various storage solutions, ensuring that users can choose the most suitable storage devices for their specific needs.

Improved Performance

The dual-port design of the HPE Smart Array P840AR also contributes to improved performance. By distributing the workload across multiple ports, the controller can handle higher data transfer rates and reduce the potential for bottlenecks. This results in faster data access and improved system responsiveness, especially in environments with high-demand applications or heavy workloads.

Redundancy and Failover Protection

The presence of dual ports also provides redundancy and failover protection. In the event of a port failure or disconnection, the controller can automatically switch to the alternate port without interrupting data access or system operation. This ensures continuous availability of data and minimizes the risk of data loss or downtime.

Data Transfer Rate: 12GB

The HPE Smart Array P840AR Internal SAS Controller boasts an impressive data transfer rate of up to 12GB, making it an ideal choice for users seeking high-performance storage solutions.

Fast Data Access

With its high data transfer rate, this controller enables users to access their data quickly and efficiently. Whether it's retrieving large files or running resource-intensive applications, the HPE Smart Array P840AR ensures minimal latency and maximized throughput. This is particularly advantageous for businesses that rely on fast data access for critical operations or time-sensitive tasks.

Improved System Performance

The 12GB data transfer rate also contributes to improved overall system performance. By enabling faster data transmission between the controller and storage devices, the HPE Smart Array P840AR reduces data bottlenecks and minimizes system lag. This results in smoother operation, reduced waiting times, and enhanced productivity for users.

Future-Proofing

The 12GB data transfer rate future-proofs your storage infrastructure, ensuring compatibility with upcoming technologies and storage devices. As technology continues to advance, storage devices with higher data transfer rates are likely to become more prevalent. By investing in a controller with a 12GB data transfer rate, users can ensure that their system remains compatible with future storage devices and can take full advantage of their capabilities.

Cache Memory: 2GB FBWC

The HPE Smart Array P840AR Internal SAS Controller is equipped with a 2GB FBWC (Flash-Backed Write Cache), offering significant benefits in terms of performance and data reliability.

Accelerated Write Performance

The 2GB FBWC provides a dedicated cache memory for write operations, allowing the controller to temporarily store data before writing it to the storage devices. This significantly improves write performance by reducing the latency associated with writing directly to the disks. As a result, users experience faster write speeds and improved overall system responsiveness.

Data Protection and Integrity

In addition to its performance benefits, the 2GB FBWC also enhances data protection and integrity. In the event of a power loss or system failure, the flash-backed write cache ensures that any unwritten data is preserved and can be safely written to the storage devices once power is restored. This reduces the risk of data loss or corruption and ensures the integrity of critical information.

Optimized Workload Performance

The cache memory also optimizes workload performance by intelligently managing data access. Frequently accessed data can be stored in the cache, allowing for faster retrieval and reducing the load on the storage devices. This is particularly advantageous in environments with high-demand applications or databases, as it minimizes latency and improves overall system efficiency.
