IBM Emulex LPE12004 8Gb Quad Port FC Host Bus Adapter HBA – 00WT000 + 4x 8Gb SFP
IBM FC:5729FRU:00WT000 LPE12004
Architectural Overview and Core Capabilities
The IBM Emulex LPe12004 serves as a foundational component for high-density enterprise storage infrastructure, delivering high-performance connectivity across four fully independent physical channels. Recognized in IBM environments by FRU P/N 00WT000 and Feature Code 5729 (CCIN 5729), this full-height card utilizes a native PCI Express 2.0 x8 host interface. By engineering four distinct 8Gb paths onto a single adapter layout, it significantly reduces slot consumption within the server chassis while delivering an aggregate full-duplex bandwidth capability of up to 34 Gbps.
The underlying architecture relies on the advanced Emulex Saturn controller engine. This processor integrates dedicated onboard data buffers and deep execution queues designed to sustain continuous, heavy block I/O operations without causing memory allocation bottlenecks on the host system.
