Product Description
The IBM 57B3 is a Host Bus Adapter (HBA) designed to provide high-speed connectivity for storage devices within IBM System x servers and compatible workstations. Equipped with two Serial Attached SCSI (SAS) ports, it facilitates the connection of both SAS and SATA hard drives, as well as tape drives. The adapter operates at a data transfer rate of 3Gb/s per port, ensuring efficient data flow for storage-intensive applications and operations. Featuring a PCI Express x8 interface, the 57B3 leverages the bandwidth capabilities of PCIe 2.0, offering significant performance improvements over older PCI interfaces. Its low-profile form factor makes it ideal for deployment in dense server chassis, such as 1U or 2U rack-mount systems, where space is at a premium. The adapter's design prioritizes reliability and ease of maintenance, including support for hot-plug functionality, which allows for the addition or removal of storage devices without the need to power down the system.
