This enables efficient data distribution across multiple drives, enhancing performance and ensuring redundancy.

Support for Multiple RAID Levels

The two ports of the Smart Array P840AR enable the implementation of different RAID (Redundant Array of Independent Disks) levels, such as RAID 0, RAID 1, RAID 5, RAID 6, and RAID 10. Each RAID level offers unique benefits in terms of performance, data protection, and capacity utilization. Users can configure the controller to meet their specific needs and create a reliable and efficient storage environment.

Hot-Swap Capabilities

With two ports, the Smart Array P840AR supports hot-swapping of drives. Hot-swapping allows users to replace or add drives without powering down the system, minimizing downtime and ensuring continuous operation. This feature is particularly advantageous in environments where uninterrupted access to data is critical.

Expandability

The two ports of the Smart Array P840AR provide expandability options for future storage needs. Users can easily add more drives or expand their storage capacity by utilizing the available ports. This scalability ensures that the controller can adapt to evolving requirements without the need for significant hardware upgrades or replacements.

Data Transfer Rate: 12GB

The HPE Smart Array P840AR Internal SAS Controller offers an impressive data transfer rate of 12GB per second. This high-speed data transfer capability brings numerous benefits to users, making it a key feature of the controller.

Compatibility with Existing Infrastructure

The Smart Array P840AR's 12GB data transfer rate is backward compatible with lower-speed SAS devices, including 6GB and 3GB SAS drives. This compatibility ensures seamless integration with existing infrastructure, allowing users to upgrade their storage infrastructure gradually without disrupting operations or requiring a complete overhaul.

Cache Memory: 2GB FBWC

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

Enhanced Performance

The 2GB FBWC provides a high-speed cache for frequently accessed data, allowing for faster read and write operations. By temporarily storing data in the cache memory, the Smart Array P840AR can reduce latency and improve overall system performance. This is particularly beneficial for applications that rely on random access to data, such as databases and virtual machines.

Data Protection

The FBWC memory acts as a buffer between the host system and the storage drives, ensuring that data is safely stored in the event of a power loss or system failure. The Smart Array P840AR utilizes the flash-backed technology, which means that even if power is lost, the data stored in the cache memory will not be lost or corrupted. This protects against data loss and helps maintain data integrity.

Improved Reliability

By utilizing FBWC, the Smart Array P840AR can optimize data writes by temporarily storing them in the cache memory before writing them to the drives. This reduces the wear and tear on the drives and extends their lifespan. The controller's cache management algorithms also help improve reliability by ensuring that data is written to the drives efficiently and accurately.

Flexibility and Customization

The Smart Array P840AR allows users to configure the FBWC memory according to their specific needs. They can adjust cache settings, such as read/write ratio and caching policies, to optimize performance or prioritize data protection. This flexibility ensures that users can tailor the controller's behavior to match their unique requirements and workloads.
