Product Description
The HP AH627ALP is a high-performance Host Bus Adapter (HBA) designed to connect servers to SCSI storage devices. It utilizes the Ultra320 SCSI standard, which offers a maximum theoretical data transfer rate of 320 Megabytes per second (MB/s) per channel. This adapter features a dual-channel design, meaning it has two independent SCSI controllers, which can be used to connect to twice the number of devices or to implement load balancing and redundancy for increased performance and reliability. Connectivity to the host server is provided via a PCI Express (PCIe) interface. PCIe is a modern, high-speed serial expansion bus standard that offers significantly more bandwidth than older PCI or PCI-X interfaces, ensuring that the HBA is not a bottleneck for data transfer. The adapter supports Low Voltage Differential (LVD) signaling, which is a standard for Ultra320 SCSI that allows for longer cable lengths and higher signal integrity compared to older High Voltage Differential (HVD) or Single-Ended (SE) standards. This HBA is ideal for environments that rely on SCSI-based storage, such as older SANs, direct-attached storage arrays, or high-capacity tape libraries. The dual-channel capability is particularly beneficial for servers running demanding I/O workloads, as it allows for parallel data transfers and provides a level of fault tolerance. The HP AH627ALP, part of the HP StorageWorks family, is engineered for enterprise environments requiring robust and high-speed connectivity to SCSI peripherals.
