HPE Smart Array P841 SAS-12GBPS 4-Ports PCIE 3.0 x8 FBWC Controller - 726903-B21

Interface: SAS-12GBPS

The HPE Smart Array P841 Controller is equipped with an SAS-12GBPS interface, which provides users with an exceptional level of performance and reliability. SAS (Serial Attached SCSI) is a high-speed data storage interface that allows for the connection of multiple devices, such as hard drives and solid-state drives (SSDs), to a computer system. With a data transfer rate of 12Gbps, this interface offers twice the bandwidth of its predecessor, SAS-6GBPS, enabling faster and more efficient data transfer.

Increased Speed and Performance

The SAS-12GBPS interface significantly enhances the speed and performance of storage devices connected to the HPE Smart Array P841 Controller. With its higher data transfer rate, users can experience faster read and write speeds, reducing latency and improving overall system responsiveness. This is particularly beneficial for demanding applications that require high throughput, such as databases, virtualization environments, and data-intensive workloads.

Improved Scalability

The increased bandwidth provided by the SAS-12GBPS interface allows for greater scalability when it comes to expanding storage capacity. Users can easily add additional drives or upgrade existing ones without sacrificing performance. This flexibility is crucial for businesses that need to accommodate growing data volumes and adapt to changing storage requirements over time.

Enhanced Reliability

Reliability is a vital aspect of any storage solution, and the SAS-12GBPS interface offers improved fault tolerance and data protection. With features such as error detection and correction, hot-swappability, and redundancy options like RAID (Redundant Array of Independent Disks), users can ensure the integrity and availability of their data. This level of reliability is especially important for mission-critical applications where data loss or system downtime can have severe consequences.

Ports: 4

The HPE Smart Array P841 Controller comes equipped with four ports, allowing users to connect multiple storage devices simultaneously. These ports support various types of drives, including SAS and SATA (Serial ATA), offering versatility and compatibility for a wide range of storage configurations.

Improved Data Redundancy

By connecting multiple drives to different ports on the HPE Smart Array P841 Controller, users can implement RAID configurations that enhance data redundancy and protect against drive failures. RAID technology distributes data across multiple drives, providing fault tolerance and ensuring data integrity even if one or more drives fail. The four ports on this controller allow for more extensive RAID configurations, offering additional levels of protection and peace of mind.

Increased Storage Capacity

Having four ports on the controller enables users to connect multiple drives, significantly increasing the total storage capacity of their system. This is particularly beneficial for environments that require large amounts of data storage, such as data centers, media production, and surveillance systems.

Flexible Storage Configurations

The four ports on the HPE Smart Array P841 Controller offer flexibility when it comes to storage configurations. Users can connect a combination of SAS and SATA drives, mix different drive sizes or speeds, and organize them according to their specific requirements. This flexibility enables users to optimize their storage setup based on performance, capacity, and cost considerations.

Bus Type: PCIE 3.0 x8

The HPE Smart Array P841 Controller utilizes a PCIE 3.0 x8 bus type for its connection to the computer system. PCIE (Peripheral Component Interconnect Express) is a high-speed serial computer expansion bus standard that provides faster data transfer rates compared to older bus types like PCI (Peripheral Component Interconnect).

Enhanced Throughput

The PCIE 3.0 x8 bus type offers increased throughput, allowing for faster and more efficient communication between the HPE Smart Array P841 Controller and the rest of the system. This results in improved overall system performance, particularly when handling data-intensive tasks such as large file transfers, database queries, and virtual machine operations.

Compatibility and Future-Proofing

PCIE 3.0 x8 is a widely adopted standard in modern computer systems, ensuring compatibility with a broad range of hardware configurations. By using this bus type, the HPE Smart Array P841 Controller can seamlessly integrate into existing systems and provide a future-proof solution that can support upcoming technology advancements.

Expandability and Scalability

The PCIE 3.0 x8 bus type offers ample bandwidth for expanding the capabilities of the HPE Smart Array P841 Controller. Users can connect additional devices such as network adapters, graphics cards, or storage expansion cards to further enhance their system's functionality and address evolving needs. This expandability and scalability make the controller a versatile choice for both current and future requirements.

Cache: FBWC

The HPE Smart Array P841 Controller features a Flash-Backed Write Cache (FBWC), which provides users with improved performance, data protection, and reliability. The cache is a high-speed memory used to temporarily store frequently accessed data, allowing for faster access times and reduced latency.

Accelerated Performance

The FBWC cache in the HPE Smart Array P841 Controller accelerates performance by caching frequently accessed data, reducing the need to access slower storage devices such as hard drives or SSDs. This results in faster read and write operations, improving overall system responsiveness and reducing application loading times. Users can experience a significant boost in performance, particularly for workloads that involve frequent data access or heavy I/O operations.

Data Protection and Integrity

FBWC cache provides an additional layer of data protection by temporarily storing write operations in non-volatile memory (NVM) before writing them to the underlying storage devices. In the event of a power loss or system failure, the cached data can be safely flushed to the drives, preventing data loss or corruption. This feature ensures data integrity and reduces the risk of data loss in critical situations.

Improved Reliability

The FBWC cache enhances the reliability of the HPE Smart Array P841 Controller by reducing the wear and tear on storage devices. By minimizing the number of write operations directly to the drives, the controller can extend their lifespan and improve their overall reliability. This is particularly beneficial for high-demand environments where drives are subjected to continuous read and write operations.
