The ALLNET ALL0131-2SFP-10G Server Adapters with SFP+ connectivity are the most exible and scalable Ethernet adapters for today’s de-
manding data center environments. Data center networks are being pushed to their limits. The escalating deployments of servers with multi-
core processors and demanding applications such as High Performance Computing (HPC), database clusters, and video-on-demand are driving
the need for 10 Gigabit connections. Customers require exible and scalable I/O solutions to meet the rigorous requirements of running
mission-critical applications in virtualized and uni ed storage environments.
Powered by the Intel® Ethernet 82599 10 Gigabit Ethernet Controller, the ALLNET ALL0131-2SFP-10G addresses the demanding needs of the
next-generation data center by providing unmatched features for virtualization, exibility for LAN and SAN networking, and proven, reliable
performance.
Best Choice for Virtualization
The explosive growth in virtualization is leading to an increasing demand for network performance. With more Virtual Machines (VMs) run-
ning on each multi-core server, networking traf c is dramatically increased with each VM competing for available I/O bandwidth. Intel’s family
of ALLNET ALL0131-2SFP-10G Server Adapters addresses networking bottlenecks in virtualized environments. These adapters enable network-
intensive applications to achieve the performance expected in a virtualized environment.
The ALLNET ALL0131-2SFP-10G server adapter provides the best networking performance available in the industry, whether the physical port
is con gured in an emulation mode using the virtual switch in the Virtual Machine Monitor (VMM), or is directly assigned to a virtual machine.
In the emulation mode, Intel’s I/O technology, Virtual Machine Device queues1 (VMDq) optimizes network performance by of oading data
sorting and copying from the software Virtual Switch in the VMM to the Intel Ethernet 82599 10 Gigabit Controller. This con guration is best
suited for a large number of VMs running standard applica- tions that have limited bandwidth and latency requirements.
For mission-critical applications, where dedicated I/O is required for maximum network performance, users can assign a dedicated virtual ad-
apter port to a VM. Using the PCI-SIG SR-IOV capability on an ALLNET ALL0131-2SFP-10G server adapter provides direct VM connectivity and
data protection across VMs. SR-IOV technology allows the data to bypass the software virtual switch and provides near-native performance.
It assigns either physical or virtual I/O ports to individual VMs directly. This technology is best suited for applications that demand the highest
I/O throughput and lowest latency performance such as database, storage, nancial and other applications.
PCI-SIG SR-IOV is a mechanism for devices to advertise their ability to be directly assigned to multiple virtual machines. SR-IOV allows for the
partitioning of a PCI function into many virtual interfaces for the purpose of sharing the resources of a PCI Express* (PCIe) device in a virtual
environment. These virtual interfaces are called Virtual Functions. Each virtual function
can support a unique and separate data path for I/O-related functions within the PCI Express hierarchy. Use of SR-IOV with a networking de-
vice, for example, allows the bandwidth of a single port (function) to be partitioned into smaller slices that may be allocated to speci c VMs,
or guests, via a standard interface.
The ALLNET ALL0131-2SFP-10G server adapter delivers the same functionality and throughput as ten dual-port, one gigabit adapters, saving
cost, power, and complexity.
Uni ed Networking and Storage
The family of ALLNET ALL0131-2SFP-10G server adapters lowers your data center total cost of ownership (TCO) by providing the ability to
route LAN and SAN traf c over a single fabric.
Support for Fiber Channel over Ethernet (FCoE)
FCoE encapsulates Fiber Channel frames over standard Ethernet networks, enabling Fiber Channel to take advantage of 10 GbE networks
while preserving its native protocol. The ALLNET ALL0131-2SFP-10G server adapter offer FCoE hardware acceleration to provide performance
comparable to FC HBAs. The server adapters support Data Center Bridging, also known as Converged Enhanced Ethernet (CEE), which allows
customers to con gure traf c classes and priorities to deliver a lossless Ethernet fabric. An Intel Ethernet X520 server adapter reduces TCO by
eliminating redundant fabrics and saves the cost of expensive FC HBAs and FC switch ports.
