The Emulex LightPulse® LPe1150 is a high performance 4Gb/s PCI Express x4 host bus adapter solution. The LPe1150 balances the advanced bus speeds and efficiency of PCI Express with exceptional 4Gb/s Fibre Channel performance. With unsurpassed robustness, reliability and performance, the LPe1150 provides the optimum I/O connectivity solution for a wide spectrum of server, storage and system area networks (SANs). As the successor to the enduring PCI interface, PCI Express is a new, much-anticipated bus architecture. As a host serial bus, PCI Express eliminates many of the inefficiencies of parallel PCI and PCI-X architectures. With lower pin counts and lower power consumption requirements, PCI Express host bus adapters also reduce system level power requirements. Most importantly though, PCI Express is backward compatible with PCI and PCI-X addressing, which allows all existing applications and Operating Systems to function unchanged.
