Description
Product Overview of the PCI-E 2 Port SCSI Raid Controller
The HPE 726899-001 Smart Array P840 is a high-performance RAID controller card designed for enterprise-level storage solutions. This card features a PCIe 3.0 interface and two ports to connect up to 16 SAS or SATA drives. The card also comes with 4GB of flash-backed write cache (FBWC) to enhance data transfer speeds and ensure data reliability. In this article, we will dive deeper into the specifications and features of the HPE 726899-001 Smart Array P840 controller card.
PCIe Interface
The HPE 726899-001 Smart Array P840 controller card comes with a PCIe 3.0 interface, which provides a high-speed connection to the server’s motherboard. PCIe 3.0 is the third generation of the Peripheral Component Interconnect Express (PCIe) interface, which allows for faster data transfer rates than previous generations. PCIe 3.0 has a maximum transfer rate of 8 GT/s (gigatransfers per second), which is twice as fast as PCIe 2.0.
RAID Support
The HPE 726899-001 Smart Array P840 controller card supports RAID levels 0, 1, 10, 5, 6, 50, 60, and 1 ADM (Advanced Data Mirroring). RAID (Redundant Array of Independent Disks) is a data storage technology that combines multiple physical disks into a single logical unit to improve performance, data redundancy, and data availability. The supported RAID levels determine how the data is distributed across the disks and how the data is protected in case of disk failure.
Data Transfer Speed
The HPE 726899-001 Smart Array P840 controller card features a 12GB/s data transfer rate, which is twice as fast as the previous generation of 6GB/s controllers. This faster data transfer rate enables the card to handle high-bandwidth applications and transfer large files quickly.
Flash-Backed Write Cache
The HPE 726899-001 Smart Array P840 controller card comes with 4GB of flash-backed write cache (FBWC). FBWC is a type of cache memory that uses flash memory to store data in case of a power loss or system failure. This flash memory is non-volatile, which means that it retains data even when the power is turned off. The FBWC feature helps to enhance data transfer speeds and ensures data reliability by providing a backup of the data in case of a power loss.
Connectivity
The HPE 726899-001 Smart Array P840 controller card has two ports, each capable of connecting up to 8 SAS or SATA drives. This provides a total of 16 drives that can be connected to the card. SAS (Serial Attached SCSI) and SATA (Serial ATA) are two types of interfaces used to connect hard drives to a computer system. SAS is typically used in enterprise-level storage solutions, while SATA is commonly used in desktop and laptop computers.
Compatibility
The HPE 726899-001 Smart Array P840 controller card is compatible with a wide range of HPE ProLiant servers and storage systems. The card is designed to work with HPE ProLiant Gen9 and Gen10 servers, as well as HPE Apollo servers and HPE Synergy compute modules.
Management and Monitoring The HPE 726899-001 Smart Array P840 controller card can be managed and monitored using HPE Smart Storage Administrator (SSA), which is a web-based tool that provides a central interface for managing and configuring HPE Smart Array controllers. SSA provides features such as online RAID level migration, online capacity expansion, and drive firmware updates.
