Benefits

GENERAL

Intel® 82599 10 Gigabit Ethernet Controller

Industry-leading, energy-efficient design for next-generation 10 Gigabit performance and multi-core

processors.

SFP+ Connectivity

Intel® Ethernet Server Adapter X520 Series for OCP with SFP+ connections support 10GBASE-SR,

10GBASE-LR and SFP+ Copper Direct Attach physical media.

OCP Form Factor

• Supports the OCP form factor for Server specifications revision 2

iSCSI Remote Boot v3.0

• Enables system boot-up via iSCSI

• Provides additional network management capability

RoHS-compliant

• Complies with the European Union directive 2002/95/EC to reduce the use of hazardous materials

Time Sync (IEEE 1588*, 802.1as)

• Enables networked Ethernet equipment to synchronize internal clocks according to a network mas-

ter clock; endpoint can then acquire an accurate estimate of the master time by compensating for link

latency.

Low Halogen

• Leadership in an environmentally friendly ecosystem

SMBus or NC-SI enabled

• Provides out of band (OOB) network access

I/O FEATURES FOR MULTI-CORE PROCESSOR SERVERS

Intel® Data Direct I/O (Intel® DDIO)

• Reduces memory accesses from I/O on local socket

• Speeds up CPU data transfer

• Accelerates inbound & outbound data flows

Intel® Ethernet Flow Director

• Intel Ethernet Flow Director and ATR can significantly lower latency and improve CPU utilization by pre-

serving the affinity between the flow and the core where the application resides

RSS - Receive Side Scaling

• Uses multiple queues for receive traffic

MSI-X support

• Minimizes the overhead of interrupts

• Load-balancing of interrupt handling between multiple cores/CPUs

Low Latency Interrupts (LLI)

• Based on the sensitivity of the incoming data, the adapter can bypass the automatic moderation of time

intervals between the interrupts

Multiple Queues: 128 Tx and Rx queues per port

• Network packet handling without waiting or buffer overflow providing efficient packet prioritization

Tx/Rx IP, SCTP, TCP, and UDP checksum offloading

(IPv4, IPv6) capabilities

• Lower processor usage

• Checksum and segmentation capability extended to new standard packet type

TxTCP segmentation offload (IPv4, IPv6)

• Increased throughput and lower processor usage

Interrupt Throttle Rate (ITR)

• ITR parameter controls how many interrupts each interrupt vector can generate per second.

Jumbo frames

• Supports jumbo frames larger then default 1500

Large Receive Offload (LRO)

• Combines multiple Ethernet frames into a single receive in the stack, thereby potentially decreasing CPU

usage for receives

MAC and VLAN anti-spoofing

• If a malicious driver attempts to send a spoofed packet, it is dropped by the hardware and not transmit-

ted. An interrupt is sent to the PF driver notifying it of the spoof attempt.

Flow Control

• Ethernet Flow Control (IEEE 802.3x) support for capable link partner

HW based receive side coalescing (RSC)

• Merges multiple frames from the same IPv4 TCP/IP flow into a single structure that can span one or

more descriptors.

Virtualization Features

PC-SIG SR-IOV Implementation (up to 64 virtual

functions per port)

• Provides an implementation of the PCI-SIG standard for I/O Virtualization. The physical configuration of

each port is divided into multiple virtual ports. Each virtual port is assigned to an individual virtual ma-

chine directly by bypassing the virtual switch in the Hypervisor, resulting in near-native performance.

• Integrated with Intel® VT for Directed I/O (Intel® VT-d) to provide data protection between virtual ma-

chines by assigning separate physical addresses in the memory to each virtual machine

Advanced Packet Filtering

• 24 exact-matched packets (unicast or multicast)

• 4096-bit hash filter for unicast and multicast frames

• Lower processor usage

• Promiscuous (unicast and multicast) transfer mode support

• Optional filtering of invalid frames

VLAN support with VLAN tag insertion, stripping

and packet filtering for up to 4096 VLAN tags

• Ability to create multiple VLAN segments
