LPe11000 Hardware Installation Manual Page 1
Introduction
The Emulex® LPe11000 host bus adapter (HBA) is a single-channel, 4.25 gigabit per second (Gb/s),
Fibre Channel (FC) Peripheral Component Interconnect Express (PCIe) HBA. The core technology of
this HBA is Emulex’s eighth generation FC controller. The controller incorporates a multifunction native
PCIe core that is compliant to the PCIe Base Specification 1.0a and PCI Express CEM Specification
1.0a. The HBA supports packet transfers up to 2048 bytes on the PCIe link with support for x1 or x4 lane
negotiation. The supported physical PCIe connector is x4 or higher (x8 or x16). The fully featured FC
port is compliant to various American National Standards Institute (ANSI) FC standards. The product is
targeted at FC storage networking environments that require the highest degrees of robustness,
performance and ease of management.
Major Features
