The IBM 17XX-3612 represents a specialized 1Gb iSCSI 4-Port Daughter Card, designed to offer an affordable and efficient network storage interfacing solution for servers requiring enhanced connectivity options. This daughter card facilitates the use of Internet Small Computer System Interface (iSCSI) protocol, allowing for the transmission of SCSI commands over IP networks, thus enabling remote storage access that is both cost-effective and reliable. By providing four 1Gb Ethernet ports, the card significantly increases a server's capacity to connect with iSCSI-based storage devices, supporting multiple data streams or network connections to improve redundancy and throughput. It is particularly well-suited for small to medium-sized businesses (SMBs) or enterprise environments looking to implement or expand their storage area networks (SANs) without the high cost associated with Fibre Channel. The IBM 17XX-3612 facilitates streamlined storage management, virtualization, and backup solutions, allowing for scalable and flexible storage networking configurations.
