Product overview of 766205-B21 HPE Smart Array P840 12GB/S PCIE
The 766205-B21 HPE Smart Array P840 is a RAID controller card used for managing storage in a server. It is designed for use in high-performance computing environments that require fast data transfer rates and reliable storage management. In this article, we will explain what a RAID controller card is, how the HPE Smart Array P840 works, and the benefits of using it in a server.
A RAID Controller Card
A RAID controller card is a hardware device that is installed in a server to manage storage arrays. RAID stands for Redundant Array of Independent Disks. It is a method of storing data on multiple disks to improve performance, reliability, and capacity. The RAID controller card is responsible for managing the disks and ensuring that data is stored and retrieved efficiently.
RAID controller cards come in various configurations, from simple two-disk systems to complex multi-disk setups. They can be installed in a server’s PCIe slot or integrated into the motherboard. The type of RAID controller card used depends on the server’s requirements, such as the number of disks, data transfer rate, and storage capacity.
HPE Smart Array P840
The HPE Smart Array P840 is a high-performance RAID controller card designed for use in enterprise environments. It supports up to 24 internal or external drives and provides a maximum data transfer rate of 12 Gb/s per port. The card has two ports, which means it can manage two separate storage arrays simultaneously.
The HPE Smart Array P840 uses a technology called Flash-Backed Write Cache (FBWC). FBWC is a type of cache that uses NAND flash memory to store data. It provides faster write speeds than traditional battery-backed cache and reduces the risk of data loss in the event of a power failure.
The HPE Smart Array P840 supports various RAID configurations, including RAID 0, 1, 5, 6, 10, 50, and 60. RAID 0 is a striping configuration that provides the best performance but no redundancy. RAID 1 is a mirroring configuration that provides redundancy but no performance improvement. RAID 5 is a striping with parity configuration that provides both performance and redundancy. RAID 6 is similar to RAID 5 but can tolerate two disk failures instead of one. RAID 10 is a combination of mirroring and striping that provides both performance and redundancy. RAID 50 and 60 are combinations of striping and parity that provide both performance and redundancy across multiple RAID 5 or RAID 6 arrays.
Benefits of Using the HPE Smart Array P840
The HPE Smart Array P840 offers several benefits over other RAID controller cards. These benefits include:
- High Performance: The HPE Smart Array P840 provides a maximum data transfer rate of 12 Gb/s per port, making it suitable for high-performance computing environments that require fast data transfer rates.
- Improved Data Protection: The HPE Smart Array P840 uses FBWC technology to provide faster write speeds and reduce the risk of data loss in the event of a power failure. This improves data protection and reduces the risk of data corruption.
- Flexible Configuration: The HPE Smart Array P840 supports various RAID configurations, including RAID 0, 1, 5, 6, 10, 50, and 60. This makes it suitable for a wide range of server environments.
- Scalability: The HPE Smart Array P840 supports up to 24 internal or external drives, making it suitable for large-scale storage environments.
- Easy Management: The HPE Smart Array P840 comes with a web-based management interface that allows administrators to easily configure and manage storage arrays.
