Emulex LP982
2GB/s Fibre Channel PCI-X Host Bus Adapter
The LP982 PCI-X host bus adapter offers a highly integrated 2Gb/s Fibre Channel HBA for use in servers based on either PCI or the latest PCI-X expansion bus. The LP982 delivers exceptional performance through the use of an Emulex Pegasus ASIC, a 266MIPs onboard processor, an embedded 1Gig/2Gig SERDES, and a high performance unified QDR SRAM. The LP982 features automatic topology detection and automatic speed negotiation capability. These capabilities allow complete compatibility with existing 1Gb/s Fibre Channel SANs, while allowing seamless upgrades to higher speed 2Gb/s SANs.
The features of this PCI-X based HBA provide the flexibility and broad interoperability needed for complex, highly scalable SANs. The LP982 provides a combination of features, including switched fabric support using F_Port and FL_Port connections, full-duplex data transfers, high data integrity features, support for all Fibre Channel topologies, and support for service classes 2 and 3.
The LP982 also features sophisticated hardware that provides superior performance in SANs and provides best in class server CPU offload. This exclu-sive hardware delivers low latency and high throughput in switched fabric, arbitrated loop and clustered environments. Support for fiber optic cabling is provided through an embedded small form factor (LC) optical interface.

Driver Support
A rich suite of software complements the LP982. Some examples of the features included are, LUN Masking, LUN Mapping, Persistent Binding, I/O Coalescing, full fabric boot as well as support for multi or simul-taneous protocol (SCSI & IP) operation. In addition, most drivers include a full-featured implementation of the FC-MI HBA Management Interface. These features enable advanced storage area network (SAN) implementations in Windows 2000, Windows NT, Linux, and NetWare environments. All drivers are also fully compatible with the Emulex LP9002L, LP850, LP8000, LP7000E, LP952L, LP9402DC, LP9002C and LP9802 host bus adapters.
