Product Description
The HP 129281-001 is a robust Host Bus Adapter (HBA) designed to provide high-performance connectivity for SCSI storage devices. Utilizing the PCI-X interface, it leverages the increased bandwidth capabilities of this bus architecture compared to standard PCI, making it suitable for demanding storage applications. This adapter features dual channels, each supporting Ultra3 SCSI (also known as Ultra160 SCSI) protocol. Ultra3 SCSI offers a significant performance boost over previous generations, capable of delivering data transfer rates of up to 160 MB/s per channel, enabling faster access to storage arrays and peripherals. Each of the two independent SCSI channels can support up to 16 devices, allowing for a total of 32 SCSI devices to be connected to a single HBA. This makes it an excellent choice for servers or workstations requiring extensive internal or external SCSI storage configurations, such as multiple hard drives, RAID arrays, or tape backup units. The adapter supports both Low Voltage Differential (LVD) and Single-Ended (SE) SCSI signaling, providing compatibility with a wide range of SCSI devices. The Low Profile (LP) form factor ensures that it can be installed in smaller chassis or systems with limited internal space, while still offering full functionality. This HBA is engineered for reliability and performance, making it a critical component for systems that require dependable data access and transfer. It is compatible with a variety of operating systems and server platforms that support the PCI-X bus. The HP 129281-001 is an ideal solution for upgrading existing SCSI storage infrastructure or for building new systems that require high-capacity, high-speed, and reliable connectivity to SCSI-based storage solutions, ensuring efficient operation for applications such as file servers, database servers, and backup systems.
