The IBM 5783 is an iSCSI Host Bus Adapter (HBA) that provides a reliable, high-performance interface between PCI-X compatible servers and iSCSI storage networks. Utilizing copper cabling, this adapter is designed to leverage existing Ethernet infrastructure to access iSCSI SANs (Storage Area Networks), making it an economical option for expanding storage capacity without the need for specialized fiber optic cabling. The adapter supports boot-from-SAN capability, allowing servers to boot directly from a remote iSCSI storage device, thereby enhancing disaster recovery strategies and simplifying server deployment and management. With support for advanced features such as jumbo frames and TCP/IP offload engine (TOE), the IBM 5783 offloads processing tasks from the server's CPU, improving overall system performance and efficiency in virtualized environments, media streaming, backup, and recovery applications.
