Cache Memory

The HPE Smart Array P840AR Internal SAS Controller comes equipped with an impressive 2GB FBWC (Flash-Backed Write Cache) cache memory, providing significant performance benefits and ensuring data integrity during power outages or system failures.

Benefits of 2GB FBWC Cache Memory

Enhanced Write Performance

The 2GB FBWC cache memory acts as a buffer between the controller and the drives, effectively improving write performance. When data is written to the drives, it is first stored in the cache memory before being written to the drives. This allows for faster write operations, as data can be written to the cache memory at a high speed and then gradually flushed to the drives at their optimal speed. This caching mechanism significantly enhances overall system performance, especially for applications that involve frequent write operations, such as databases or transactional systems.

Data Protection

The FBWC technology used in the HPE Smart Array P840AR ensures data protection in the event of power outages or system failures. As the cache memory is backed by flash memory, any data stored in the cache is preserved even during power loss. This ensures that data is not lost or corrupted due to unforeseen events, providing an added layer of security for critical applications and sensitive information.

Improved System Reliability

The presence of a cache memory with FBWC enhances system reliability by reducing the impact of drive latencies or performance fluctuations. In cases where drives experience temporary slowdowns or higher latencies, the cache memory absorbs these variations and maintains a consistent data transfer rate. This improves overall system stability and minimizes the risk of performance degradation, ensuring that applications continue to operate smoothly even under demanding conditions.

Reduced I/O Overhead

By utilizing cache memory, the HPE Smart Array P840AR reduces I/O (input/output) overhead on the drives. Instead of performing every read or write operation directly on the drives, the controller can leverage the cache memory to store frequently accessed data temporarily. This reduces the number of I/O operations required on the drives, resulting in improved efficiency and reduced wear and tear on the drives. As a result, the overall lifespan of the drives can be extended, leading to potential cost savings for users.

Scalability and Flexibility

The 2GB FBWC cache memory offers scalability and flexibility for storage solutions. With a significant amount of cache memory, users can accommodate larger workloads and handle bursty operations more effectively. This scalability ensures that the controller can adapt to changing data demands without sacrificing performance or reliability. Additionally, the HPE Smart Array P840AR allows users to customize their caching policies, tailoring them to specific application requirements and optimizing performance based on workload characteristics.
