Interface: PCIe

The HPE Smart Array P840 Raid Controller is equipped with a PCIe interface, which stands for Peripheral Component Interconnect Express. This PCIe interface is a high-speed serial computer expansion bus standard that offers numerous benefits and plays a crucial role in enhancing the performance and efficiency of the raid controller.

Benefits of PCIe Interface

1. High Bandwidth

One of the key advantages of the PCIe interface is its increased bandwidth. It provides significantly faster data transfer rates compared to older interfaces like PCI and PCI-X. This increased bandwidth allows for faster communication between the raid controller and other components in the system, resulting in improved overall system performance.

2. Scalability

PCIe offers excellent scalability, allowing for seamless integration of multiple devices and expansion cards. This means that users can easily add additional storage devices, network adapters, or any other PCIe-enabled hardware to their system without facing compatibility issues. The ability to scale the system with ease ensures that users can adapt their infrastructure to meet growing storage demands.

3. Low Latency

The PCIe interface provides low latency, which means that data can be transferred quickly and efficiently between the raid controller and other connected devices. This reduced latency is particularly important for storage-intensive applications and environments where fast access to data is critical.

4. Improved Power Efficiency

Compared to its predecessors, PCIe offers improved power efficiency. This is achieved through various power-saving features implemented in the interface, such as dynamic power allocation and link power management. By optimizing power consumption, the raid controller can operate more efficiently, resulting in reduced energy costs and a greener IT infrastructure.

5. Future-Proof Technology

PCIe has become the industry standard for high-speed interconnects, ensuring compatibility with future generations of hardware. As new technologies and devices emerge, the PCIe interface will continue to evolve and support the latest advancements in storage and networking. By investing in a raid controller with a PCIe interface like the HPE Smart Array P840, users can future-proof their infrastructure and avoid potential compatibility issues down the line.

Ports: 2

The HPE Smart Array P840 Raid Controller is equipped with two ports, providing users with flexibility and expandability options for their storage infrastructure.

Benefits of Two Ports

1. Increased Connectivity

Having two ports on the raid controller allows for increased connectivity options. Users can connect multiple drives, expanders, or backplanes to the controller, enabling them to create larger storage arrays or implement redundancy for improved data protection. The additional port also provides fault tolerance, ensuring that if one port fails, the other can continue to operate and maintain access to the storage devices.

2. Enhanced Performance

With two ports, users can take advantage of advanced RAID configurations such as RAID 1+0 (RAID 10) or RAID 5+0 (RAID 50). These configurations distribute data across multiple drives for increased performance and fault tolerance. By utilizing multiple ports on the raid controller, users can achieve higher throughput and I/O capabilities, resulting in improved overall system performance.

3. Simplified Management

Having two ports simplifies the management of storage infrastructure. Users can separate different types of drives or configure separate arrays on each port, allowing for better organization and management of data. This separation also enables users to allocate resources more efficiently, optimizing performance for specific workloads or applications.

4. Flexibility for Expansion

The presence of two ports provides flexibility for future expansion. Users can easily add additional storage devices or expanders to the raid controller without the need for additional hardware or complex configurations. This flexibility ensures that the storage infrastructure can grow alongside the organization's needs, saving time and reducing costs associated with system upgrades.

Data Transfer Rate: 12GB/s

The HPE Smart Array P840 Raid Controller offers an impressive data transfer rate of 12GB/s, providing users with exceptional performance and responsiveness for their storage systems.

Benefits of 12GB/s Data Transfer Rate

1. Improved Workload Performance

The high data transfer rate of 12GB/s enables faster access to data, resulting in improved workload performance. Whether it is processing large amounts of data or running intensive applications, the raid controller can quickly retrieve and deliver information, reducing latency and enhancing overall system responsiveness.

2. Enhanced Multi-User Environments

In multi-user environments where multiple users are accessing the storage infrastructure simultaneously, a high data transfer rate is crucial. With 12GB/s, the raid controller can efficiently handle multiple requests, ensuring smooth and uninterrupted operations for all users. This is especially important in scenarios such as virtualization or database environments that demand high levels of concurrent data access.

3. Quick Data Backups and Restores

The fast data transfer rate facilitates quick backups and restores, minimizing downtime and reducing the risk of data loss. With 12GB/s, large amounts of data can be transferred to backup devices or restored from backups in a shorter amount of time, enabling organizations to meet their recovery point objectives (RPOs) and recovery time objectives (RTOs) more efficiently.

4. Future-Proof Performance

By offering a data transfer rate of 12GB/s, the HPE Smart Array P840 Raid Controller ensures compatibility with modern storage devices that support higher speeds. This future-proofs the infrastructure, allowing users to leverage the advantages of faster storage technologies as they become available without the need for a controller upgrade.

Cache Memory: 4GB FBWC

The HPE Smart Array P840 Raid Controller is equipped with 4GB of Flash-Backed Write Cache (FBWC) memory, providing users with significant benefits in terms of data protection, performance, and flexibility.

Benefits of 4GB FBWC Cache Memory

1. Improved Data Protection

The FBWC feature in the raid controller's cache memory provides an additional layer of data protection. In the event of a power outage or system failure, the cache memory acts as a temporary buffer, storing data that has not yet been written to the storage devices. This ensures that critical data is not lost and can be written to the drives once power is restored or the system recovers.

2. Enhanced Write Performance

The presence of a 4GB FBWC cache improves write performance by allowing the raid controller to quickly acknowledge write requests and store them in cache memory before writing them to the drives. This caching mechanism reduces latency and optimizes write operations, resulting in faster overall system performance and improved user experience.

3. Flexibility for Read/Write Operations

The cache memory provides flexibility for read/write operations. Frequently accessed data can be stored in cache memory, allowing for faster retrieval and reducing the reliance on slower mechanical storage devices. This flexibility enables organizations to optimize their storage infrastructure based on their specific workload requirements, ensuring that critical data is readily available when needed.

4. Reduces I/O Operations

By utilizing cache memory, the raid controller can reduce the number of I/O operations required to access data from the storage devices. This optimization minimizes the strain on the drives, prolonging their lifespan and improving overall system reliability. Additionally, it frees up system resources, allowing for more efficient utilization of CPU and memory resources for other tasks.
