Introduction
This manual describes Emulex
®
LP21000 and LP21002, multi-protocol PCI-Express Converged
Network Adapters (CNAs) for a 10 Gigabit Enhanced Ethernet (EE) fabric. Emulex CNAs provide both
traditional networking interface card (NIC) functionality and host-bus-adapter (HBA) functionality, as well
as Fibre Channel over Ethernet(FCoE) functionality for convergence of Fibre Channel traffic onto 10
Gigabit EE fabric.
Emulex CNAs combine four major functional components: a 10G networking MAC, a Fibre Channel IOC,
a PCI-express-switch (to bridge between the MAC and IOC), and a bridge chip that interconnects the
10G MAC and Fibre Channel IOC and interfaces with a unified lossless Ethernet switch. The CNA
serves as a common interface for both storage and IP traffic retaining familiar Fibre Channel and
networking software stacks, OS drivers, and management. The supported PCIe connector is x8 or
higher. Each CNA is compliant to the PCI Express Base Specification 1.1.
Major Features
•
Available in four different models:
•
LP21000-M single port with Optics
•
LP21002-M dual port with Optics
•
LP21000-C single port with Copper
•
LP21002-C dual port with Copper
•
Single 8-lane standard Gen 1, PCIe interface shared by the Fibre Channel and MAC controllers
through an IDT 3-port PCIe switch.
•
Standard PCIe form factor PCBA; full height, 9.1" long.
•
10 GbE Network interface connections using optics or copper.
•
On-board flash memory: 8M bytes for Fibre Channel controller program storage, 1M byte for
FCoE Bridge program storage, and 128K bytes for PXE Ethernet boot.
•
On-board configuration EEPROM for the Ethernet MAC and FCoE Bridge.
•
Uses standard Emulex SLI drivers.
•
Interoperates with existing Fibre Channel SAN infrastructures - switches, arrays, SRM tools
(including Emulex utilities), SAN practices, etc.
•
Unified Ethernet to Fibre Channel SAN connectivity provided by FCoE switch.
•
Provides 10G MAC features such as MSI-X support, Jumbo frames support (16K bytes), VLAN
tagging (802.1Q, PER priority pause / priority flow control), and advance packet filtering.
•
No host operating system changes required - i.e. NIC and HBA functionality (including device
management, utilities, etc.) transparent to the host operating system.
•
Target Systems: Tier-1 OEM rack servers of all form-factors (with PCI-Express)
