The HPE 726899-001 Smart Array P840 is a high-performance RAID (Redundant Array of Independent Disks) controller card designed for servers and storage systems. This PCI Express 3.0 x8 card supports up to 12Gb/s SAS (Serial Attached SCSI) or SATA (Serial ATA) connectivity with two internal and two external SAS ports. It features 4GB Flash-Backed Write Cache (FBWC) memory that helps to improve performance and data reliability.
RAID TechnologyRAID technology is used to improve the performance, reliability, and fault tolerance of computer storage systems. RAID controller cards manage multiple hard drives and present them as a single logical drive to the operating system. RAID levels define the way in which data is distributed across the physical drives and provide different levels of performance, redundancy, and fault tolerance.
RAID levels supported by the HPE Smart Array P840 include RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, RAID 50, and RAID 60. RAID 0 offers the best performance but no redundancy, while RAID 1 offers mirroring for fault tolerance but no performance gain. RAID 5 and RAID 6 offer both performance and redundancy, with RAID 6 offering higher fault tolerance than RAID 5. RAID 10, RAID 50, and RAID 60 are combinations of RAID levels that provide different levels of performance, redundancy, and fault tolerance.
PCI Express InterfaceThe HPE Smart Array P840 uses the PCI Express (PCIe) interface to communicate with the server's motherboard. PCIe is a high-speed serial computer expansion bus standard that provides high-speed communication between various hardware components. The PCIe 3.0 x8 interface used by the HPE Smart Array P840 provides a maximum bandwidth of 8GB/s.
SAS and SATA ConnectivityThe HPE Smart Array P840 supports both SAS and SATA connectivity. SAS is a serial communication protocol used to transfer data between computer components. It is designed for high-speed data transfer and provides better performance than SATA. SAS also supports a greater number of devices per port than SATA. SATA, on the other hand, is a cheaper and more widely available technology that is suitable for lower-end storage systems.
Flash-Backed Write CacheThe HPE Smart Array P840 features 4GB Flash-Backed Write Cache (FBWC) memory that helps to improve performance and data reliability. Write cache is a temporary storage area used to speed up write operations to the hard drives. In case of power loss or system failure, data in the write cache can be lost, which can cause data corruption or loss. FBWC uses flash memory to back up the write cache, providing data protection in case of power loss or system failure.
CompatibilityThe HPE Smart Array P840 is compatible with a wide range of HPE ProLiant servers and storage systems. It is also compatible with third-party servers that support PCIe 3.0 x8 interface and SAS or SATA connectivity. However, before purchasing the HPE Smart Array P840, it is important to check the compatibility with your server or storage system.
In Summary, the HPE Smart Array P840 is a high-performance RAID controller card designed for servers and storage systems. It supports up to 12Gb/s SAS or SATA connectivity with two internal and two external SAS ports. It features 4GB Flash-Backed Write Cache (FBWC) memory that helps to improve performance and data reliability. The HPE Smart Array P840 supports a wide range of RAID levels and is compatible with a wide range of HPE ProLiant servers and storage systems.
