DCB allocates a share of link bandwidth to FCoE traffic with ETS
Power Management
Wake on LAN (WOL) is not supported.
Adaptive Interrupt Frequency
The adapter driver intelligently adjusts host interrupt frequency based on traffic
conditions to increase overall application throughput. When traffic is light, the
adapter driver interrupts the host for each received packet, minimizing latency.
When traffic is heavy, the adapter issues one host interrupt for multiple,
back-to-back incoming packets, preserving host CPU cycles.
ASIC with Embedded RISC Processor
The core control for QLogic 8400/3400 Series adapters resides in a tightly
integrated, high-performance ASIC. The ASIC includes a RISC processor that
provides the flexibility to add new features to the card and adapt to future network
requirements through software downloads. In addition, the adapter drivers can
exploit the built-in host offload functions on the adapter as host operating systems
are enhanced to take advantage of these functions.
QLogic Control Suite
QLogic Control Suite (QCS) is an integrated utility that provides useful information
about each network adapter that is installed in your system. The QCS utility also
enables you to perform detailed tests, diagnostics, and analyses on each adapter.
You can also modify property values and view traffic statistics for each adapter.

Adapter Specifications
Physical Characteristics
The QLogic 8400/3400 Series Adapters are implemented as low-profile PCIe
cards. The adapters ship with a full-height bracket for use in a standard PCIe slot
or an optional spare low-profile bracket for use in a low-profile PCIe slot.
Low-profile slots are typically found in compact servers.
