Introduction

The Intel X520 and X540 Dual Port 10 GbE adapters for System x are powered by reliable and proven 10 Gb Ethernet technology. These adapters offer full line-rate 10 Gbps performance for high-IO intensive applications, and showcase the next generation in 10 GbE networking features for the enterprise network and data center. For ThinkServer, the X520 and X540 adapters also include FCoE and iSCSI Converged Ethernet support.

The Intel X520 adapter provides SFP+ based connectivity options (fiber or DAC cabling). The Intel X540 adapter offers 10GBASE-T connectivity with RJ-45 ports, with compatibility with the existing 1000BASE-T network, simplifying the transition to the 10 Gb Ethernet technology. Both the X520 and X540 are available in either standard PCIe low-profile card form factor or mezzanine card form factor.

Did you know?

In a multicore platform, the Intel X520 and X540 adapters support Intel I/O Virtualization Technology (IOVT), which helps accelerate data across the platform, therefore improving application response times. For virtualized environments, Intel Ethernet adapters offer advanced features with VMDq that lower processor utilization and increase I/O performance.

The X520 and X540 adapters are available in special mezzanine form factors for supported System x and ThinkServer systems. This form factor allows you to use the server's standard PCIe slots for other technologies.

The adapter option part numbers includes the following items:

  • One Intel 10 Gb Ethernet adapter
  • Full-height (3U) bracket attached with low-profile (2U) bracket included in the box (except for the ML2, Embedded, AnyFabric and OCP Mezz adapters)
  • Installation and warranty documentation

Note: The X520 adapters ship without any SFP+ transceivers or direct attach cables, with the exception of the X520-SR2 adapter. Cables and transceivers need to be ordered separately (see the following section for details).

Transceivers and direct-attach cables

The X520-SR2 adapter includes two SR SFP+ transceivers. All other X520 dual-port adapters have two empty SFP+ cages that support SFP+ SR transceivers and direct-attached copper (DAC) cables.

Note: The X540 adapters do not require the use of transceivers or DAC cables.

The following table lists the supported 10Gb Ethernet SFP+ optical transceivers and DAC cables for the System x adapters listed in Table 1. Both adapter ports must have the same type of transceiver or DAC cable selected.

Features

The Intel X520 and X540 adapters have the following features:

  • Load balancing on multiple processors, which increases performance on multiprocessor systems by efficiently balancing network loads across processor cores when used with Receive Side Scaling from Microsoft or Scalable I/O on Linux.
  • Header Splits and Replication in Receive helps the driver focus on the relevant part of the packet without needing to parse it.
  • Multiple queues allow packet handling without the waiting/buffer overflow, which provides efficient packet prioritization.
  • Storage offloads: The ThinkServer adapters listed in Table 2 support the following storage protocols:
    • FCoE (Data Center Bridging DCB, Converged Enhanced Ethernet CEE)
    • iSCSI

    The X520 OCP adapter for the sd350 supports iSCSI but does not support FCoE. System x servers support iSCSI boot as a software iSCSI initiator.

  • Offload features:
    • IP, TCP, and UDP checksum offload (IPv4 and IPv6)
    • TCP segmentation/large send offload (IPv4 and IPv6)
    • IPsec offload
    • MACsec offload
    • Receive Side Scaling for Windows and Scalable I/O for Linux (IPv4, IPv6, and TCP/ UDP)
  • Support for Intel Virtualization Technology (VT) with I/OAT and VMDq.
  • IEEE 802.1Q VLAN support with VLAN tag insertion, with stripping and packet filtering for up to 4096 VLAN tags.
  • IEEE 802.3x flow control support.
  • IEEE 802.1p Class of Service/Quality of Service.
  • Support for Advanced Packet Filtering.
  • Jumbo frames support (up to 9,500 bytes).
  • Support for both UEFI and PXE boot.
  • Teaming support:
    • Adapter Fault Tolerance (AFT)
    • Switch Fault Tolerance (SFT)
    • Adaptive Load Balancing (ALB)
    • Virtual Machine Load Balancing (VMLB)
    • IEEE 802.3ad (link aggregation control protocol)
  • Intel PROSet Utility for easy configuration and management.

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 improve system performance and application response times. The suite of features includes:

  • Direct Cache Access (DCA): Enables the adapter to prefetch data from the memory cache, thereby avoiding cache misses and improving application response times.
  • MSI-X interrupts: 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) and Scalable I/O: 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 processor usage and throughput levels.

The ThinkServer and OCP adapter support full iSCSI and FCoE storage protocols. The System x adapters have iSCSI support for native OS and VM iSCSI initiators and for iSCSI boot.

All adapters support IPsec and MACsec offloads that provides full 10 Gbps line-rate performance in secured environments.
