Intel I340 Ethernet Dual Port and Quad Port Server
Adapters for System x

Product Guide (withdrawn product)

Based on the Intel 82580 Gigabit Ethernet Controller, the Intel Ethernet Dual Port and Quad Port Server
Adapters for System x are Intel's fourth generation of PCI Express Gigabit Ethernet (PCIe GbE) adapters.
These adapters are based on fully integrated, multi-port PCIe 2.0 GbE controllers, providing a smaller
footprint and lower power dissipation.

In addition, these adapters offer advanced features, including support for multi-core processors and server
virtualization, as well as a scalable PCI Express 2.0 interface. Intel's first eco-friendly, halogen-free design
combines low power use and low cost for one of the best price to performance ratios in a multi-port
solution that is available today. Figure 1 shows the Intel Ethernet Quad Port Server Adapter.

Did you know?

These dual port and quad port adapters provide high-performing, multi-port gigabit connectivity in a multi­core platform as well as in a virtualized environment. In a multi-core platform, the adapter supports
technologies such as Intel QuickData Technology, MSI-X, and Low Latency Interrupts that help accelerate
data across the platform, therefore improving application response times. For virtualized environments,
Intel Ethernet adapters have advanced features with VMDq that lower CPU utilization and increase I/O
performance.

Intel I/O Acceleration Technology (Intel I/OAT) is a suite of features that improves data acceleration across
the platform, from networking devices to the chipset and processors, which helps to improve system
performance and application response times. The suite of features includes:

Intel QuickData Technology: Provides the Direct Memory Access (DMA) engine, which moves data
using the chipset instead of the CPU.

MSI-X: Minimizes the impact of I/O interrupts by load-balancing interrupts across multiple
processor cores.

Low-Latency Interrupts: Allows the adapter to bypass the automatic moderation of time intervals
between the interrupts (based on the sensitivity of the incoming data).

Receive Side Scaling (RSS): Directs the interrupts to a specific processor core based on the
application’s address.

Virtual Machine Device Queues (VMDq) reduces I/O impact on the Hypervisor in a virtualized server by
performing data sorting and coalescing in the network silicon. VMDq technology makes use of multiple
queues in the network controller. As data packets enter the network adapter, they are sorted, and packets
traveling to the same destination (or virtual machine) are grouped together in a single queue. The packets
are then sent to the Hypervisor, which directs them to their respective virtual machines. Relieving the
Hypervisor of packet filtering and sorting improves overall CPU usage and throughput levels.

The adapters have complete iSCSI support for proven native OS and VMM iSCSI initiators as well as iSCSI
boot. Historically, CRC32C computation has degraded system performance, but now with the CRC
instruction set included in the latest Intel Xeon processors, CRC validation is possible with minimal impact
to network throughput while delivering data integrity.

The adapters support the following IEEE standards:

IEEE 802.3ad (link aggregation control protocol)

IEEE 802.1Q VLANs

IEEE 1588 Precision Time Control Protocol

IEEE 802.3 2005 flow control support

IEEE 802.1p
