IBM P740小型机上的LP适配卡与普通适配卡有什么区别？
LP是Low profile的缩写，LP适配卡是比原来POWER服务器常见的普通PCI卡的高度要矮。LP卡只能插在LP插槽上使用。目前Power 740上需要选配PCIe Low Profile的扩展柜(#5610/#5685)才能支持LP的PCIe插槽。目前有13款LP卡发布，其中11块PCIe 1.0的LP卡都有对应的完全相同电器特性的普通卡对应，区别仅仅是卡的挡板高度。如下：
fc#2053 PCIe LP RAID & SSD SAS Adapter 3Gb (fc#2054/2055)
fc#5269 PCIe LP POWER GXT145 Graphics Accelerator (fc#5748)
fc#5270 PCIe LP 10Gb FCoE 2-port Adapter (fc#5708)
fc#5271 PCIe LP 4-Port 10/100/1000 Base-TX Ethernet Adapter (fc#5717)
fc#5272 PCIe LP 10GbE CX4 1-port Adapter (fc#5732)
fc#5273 PCIe LP 8Gb 2-Port Fibre Channel Adapter (fc#5735)
fc#5274 PCIe LP 2-Port 1GbE SX Adapter (fc#5768)
fc#5275 PCIe LP 10GbE SR 1-port Adapter (fc#5769)
fc#5276 PCIe LP 4Gb 2-Port Fibre Channel Adapter (fc#5774)
fc#5277 PCIe LP 4-Port Async EIA-232 Adapter (fc#5785)
fc#5278 PCIe LP 2-x4-port SAS Adapter 3Gb (fc#5901)
fc#5284 PCIe2 LP 2-port 10GbE SR Adapter
fc#5286 PCIe2 LP 2-Port 10GbE SFP+ Copper Adapter
