QLOGIC ISP2312 Dual Fibre Channel Controller
3.3 QLOGIC ISP2312 Dual Fibre Channel Controller
The ISP2312 is a highly integrated single-chip, dual-channel, bus master, Fibre Channel processor
that targets storage, clustering, and networking applications. This chip connects a conventional PCI
or PCI-X bus to one or two 1.062 or 2.125 Gbps Fibre Channel ports connected to fabric, single
arbitrated loop or point-to-point topologies.
The ISP2312 is a fully autonomous device, capable of managing multiple I/O operations and
associated data transfers from start to finish without host intervention.
The ISP2312 balances the advanced bus speeds and efficiency of PCI-X with exceptional 2-Gbps
Fibre Channel performance. Fibre Channel support for SCSI, IP, and VI (Virtual Interface) allows
the ISP2312 to target a wide spectrum of storage and system area networks (SANs).
• One serial PROM is required for the FC controller to save the configuration.
• Two SFF modules are located on the front panel and are used to transfer data via Fibre Channel.
