435709-001 HP Dual Channel 64Bit 133Mhz PCI-E 8 Internal Port SAS-SATA Host Bus Adapter

A SAS-SATA HBA (Host Bus Adapter) controller is a hardware device used to connect multiple storage devices to a computer system. SAS (Serial Attached SCSI) and SATA (Serial ATA) are two different types of interfaces used in storage devices. SAS is typically used in enterprise-level storage devices, while SATA is commonly used in consumer-level storage devices. A SAS-SATA HBA controller allows a computer system to manage both types of storage devices.
