Product overview of HP 435129-B21 256MB PCI Express
The HP 435129-B21 is a RAID controller designed for use in servers and workstations. This device provides hardware RAID capabilities and supports both SATA and SAS drives. It uses the PCI Express x8 interface and can provide data transfer rates of up to 3Gbps. In this article, we will take a closer look at the features of this RAID controller and discuss its benefits and potential use cases.
A RAID controller is a hardware device that manages the data storage subsystem in a computer or server. It uses a RAID (Redundant Array of Independent Disks) configuration to provide improved data reliability, performance, or both. RAID controllers can be either software-based or hardware-based. Software-based RAID relies on the CPU of the host computer to manage the RAID array, while hardware-based RAID uses a dedicated hardware device to perform this task. Hardware RAID is generally faster and more reliable than software RAID.
PCI Express x8 Interface
The HP 435129-B21 RAID controller uses the PCI Express x8 interface. PCI Express is a high-speed serial computer expansion bus standard that connects devices to a computer's motherboard. The x8 designation refers to the number of lanes used by the interface. A PCI Express x8 interface provides eight lanes, allowing for higher data transfer rates than a x4 or x1 interface.
SATA and SAS Support
The HP 435129-B21 RAID controller supports both SATA and SAS drives. SATA (Serial Advanced Technology Attachment) is a popular interface used for connecting hard drives and solid-state drives (SSDs) to a computer's motherboard. SAS (Serial Attached SCSI) is a more advanced interface that provides higher data transfer rates and supports more devices than SATA. SAS drives are often used in enterprise-level servers and workstations.
The HP 435129-B21 RAID controller is a hardware-based RAID device. This means that it has its own processor and memory, allowing it to offload the RAID processing from the host computer's CPU. Hardware RAID devices are generally faster and more reliable than software RAID devices, as they are not dependent on the host computer's processing power or operating system.
The HP 435129-B21 RAID controller has a built-in cache of 256MB. Cache is a type of memory used to temporarily store frequently accessed data. The larger the cache, the faster the RAID controller can access frequently used data, resulting in improved performance. A 256MB cache is a relatively large cache size, which can provide significant performance benefits.
The HP 435129-B21 RAID controller supports several RAID levels, including RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, and RAID 50. RAID 0 provides improved performance by striping data across two or more drives. RAID 1 provides improved data reliability by mirroring data across two or more drives. RAID 5 and RAID 6 provide improved data reliability and performance by using parity data to recover lost data in the event of a drive failure. RAID 10 and RAID 50 combine the benefits of striping and mirroring to provide improved performance and data reliability.
Benefits of the HP 435129-B21 RAID Controller
The HP 435129-B21 RAID controller provides several benefits, including:
Improved Data Reliability
RAID controllers provide improved data reliability by using redundancy to protect against data loss in the event of a drive failure. The HP 435129-B21 RAID controller supports several RAID levels, including RAID 1, RAID 5, and RAID 6, which provide varying degrees of data protection.
RAID controllers can also provide improved performance by striping data across two or more drives. The HP 435129-B21 RAID controller supports several RAID levels

What is the primary function of a PCI e controller?
The primary function of the PCI e controller on your computer device is that it serves as the standard interface between your device's primary circuit board, and other external, peripheral components. This affects key areas of your device's functionality, such as graphics, memory, and storage ability.
The PCIe controller is built to oversee point-to-point connections in the context of non-core components. The additional "e" in PCI-e is short for "express", which is a term that was added by manufacturers in a bid to distinguish the new standard of PCIe controllers from the older PCI models.
The supporting PCIe size simply means the number of direct connections that a PCIe slot or card can provide. It can be PCIe x1, PCIe x4, PCIe x8, and PCIe x16. The cutting-edge PCIe 4.0 has a bandwidth capacity of 64 gigabytes per second and transfers at a rate of 16 gigatransfers per second (GT/s).
Why is a good PCIe controller so important?
- Connectivity: A PCIe controller is a vital link between your computer's primary circuit board and other peripheral components. This important function makes this little device indispensable.
- Speed: A PCIe controller impacts speed. Changing the PCIe controller notably improves transfer speeds, drastically increasing the amount of data that can be communicated in a second.
- Upgrades: Multiple PCI express slots present an exciting opportunity for big upgrades in the future.
Some common PCI e controller terms
- Expander card: PCIe card, expansion card, and expander card are all common terms used to refer to hardware, some of which include the Central Processing Unit (CPU), graphics card, or SSDs.
- Host Bus Adapter: This device connects your computer to other networks and storage devices, with your computer playing the role of the host system.
- RAID controller: This device oversees the hard disk drives and translates them into a logical language your computer can understand.
