The HP 462830-B21 is a RAID controller designed to enhance the performance, scalability, and data protection capabilities of servers. The controller supports both SAS and SATA drives and can be used with various HP servers, including ProLiant DL and ML series. In this article, we will delve deeper into the features and benefits of the HP 462830-B21 Dual Ports PCI Express SAS/SATA FBWC RAID Controller.
A RAID ControllerRAID (Redundant Array of Independent Disks) is a storage technology that uses multiple hard drives to enhance data protection, performance, and capacity. A RAID controller is a hardware device or software program that manages the RAID configuration and data access.
RAID levels can range from 0 to 6, each offering a different level of data protection and performance. For example, RAID 0 offers high performance but no data redundancy, while RAID 1 provides data redundancy but lower performance.
Features of HP 462830-B21 SAS/SATA FBWC RAID ControllerDual Ports
The HP 462830-B21 Dual Ports PCI Express SAS/SATA FBWC RAID Controller has two SAS/SATA ports, allowing it to support up to 8 drives. This feature provides greater flexibility and scalability when expanding storage capacity.
PCI Express InterfaceThe controller uses a PCI Express interface, which delivers high-speed data transfer rates and low latency. This interface also ensures compatibility with various servers and operating systems.
SAS and SATA SupportThe HP 462830-B21 RAID Controller supports both SAS and SATA drives, giving users the flexibility to choose the type of drive that best fits their needs. SAS drives offer higher performance, while SATA drives are more affordable.
FBWC TechnologyFlash-Backed Write Cache (FBWC) is a technology that uses flash memory to cache data. This technology enhances the performance of the RAID controller by reducing the time it takes to write data to the hard drives. The HP 462830-B21 Dual Ports PCI Express SAS/SATA FBWC RAID Controller comes with a 512MB DDR2 SDRAM memory module and can be upgraded to 2GB.
RAID LevelsThe HP 462830-B21 Dual Ports PCI Express SAS/SATA FBWC RAID Controller supports various RAID levels, including RAID 0, 1, 5, 6, 10, 50, and 60. These levels provide different levels of data protection, performance, and capacity.
RAID Migration and ExpansionThe HP 462830-B21 Dual Ports PCI Express SAS/SATA FBWC RAID Controller supports online RAID migration and expansion. This feature allows users to change the RAID level or add new drives without shutting down the system.
Battery-Free DesignThe HP 462830-B21 Dual Ports PCI Express SAS/SATA FBWC RAID Controller uses FBWC technology instead of batteries to protect cached data. This design eliminates the need for periodic battery replacement and reduces the risk of data loss due to battery failure.
Benefits of HP 462830-B21 Dual Ports PCI Express SAS/SATA FBWC RAID ControllerImproved Performance
The HP 462830-B21 Dual Ports PCI Express SAS/SATA FBWC RAID Controller enhances the performance of servers by providing faster data transfer rates and reducing the time it takes to write data to the hard drives.
Increased Data ProtectionThe HP 462830-B21 Dual Ports PCI Express SAS/SATA FBWC RAID Controller provides data protection through various RAID levels and FBWC technology. These features ensure that data is safe and can be quickly recovered in the event of a drive failure.
