The QLogic 3000 Series of Intelligent Ethernet Adapters includes the QLE3044, which features four 1GbE ports with industry-standard RJ45 connectors. The QLE3044 is a high-performance adapter that supports numerous stateless offloads for reducing server CPU utilization and increasing overall system performance.

The QLE3044 operates at 1000/100/10 Mbps data rates, ensuring backwards compatibility with legacy Ethernet hardware. And the adapter’s ultra-low power consumption makes it the most power-efficient quad-port Gigabit Ethernet Adapter on the market.

  • PCI Express Gen2 host bus support
  • NetSlice I/O
  • Four ports for teaming and failover
  • RoHS compliant

QLE3044 Intelligent Ethernet Adapter.
The QLE3044 is a quad port 1GbE Intelligent Ethernet adapter designed for various applications such as virtualization; network security appliances; cluster computing; IP content delivery systems; grid computing; database clustering; Network Attached Storage (NAS); and storage and backup servers.

Performance Optimized.
The QLE3044 is a high-performance Intelligent Ethernet adapter that can support offload of TCP/IP tasks, significantly improving throughput of servers, server appliances, and storage platforms, all while reducing host CPU utilization. This allows overall system performance to scale dramatically.

NetSlice Technology.
In the dynamic data center environment, managers need flexible solutions that can evolve along with the technology to protect current investments in virtualization and server consolidation. The QLogic NetSlice architecture addresses these requirements by incorporating a unique degree of programmable support for virtualization. The NetSlice architecture creates a platform that exports a number of independent virtual interfaces, with each virtual interface utilizing a share of the existing (hardware) resources. Each virtual interface is serviced in a fair manner. Optionally, each interface can be assigned a priority that determines how much of a share of the underlying resources are allocated to that interface. Strong isolation is built around each interface to ensure that one interface does not adversely affect another.

Investment Protection.
The QLE3044 is built around QLogic's revolutionary Protocol Processing Engine architecture and allows for the support of multiple protocols on the same hardware. QLogic also uses common drivers across all Intelligent Ethernet (10GbE and 1GbE) adapters, which reduces Total Cost of Ownership (TCO).

Unmatched Expertise.
QLogic is a leading supplier of high performance network infrastructure solutions including Fibre Channel, Ethernet, iSCSI, InfiniBand, and Converged Network adapters.
