E10GSFPSR Datasheet, PDF (2/5 Pages) Intel Corporation – Dual- and Single-Port 10 Gigabit SFP+ Ethernet Converged Network Adapters Provide Ultimate Flexibility and Scalability in Virtual and Unified Storage Environments

PCI-SIG SR-IOV is a mechanism for devices
to advertise their ability to be directly
assigned to multiple virtual machines.
SR-IOV enables the partitioning of a
PCI Express* (PCIe) function into many
virtual interfaces for the purpose of
sharing the resources of a 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 PCIe hierarchy. Use
of SR-IOV with a networking device, for
example, enables the bandwidth of a
single port (function) to be partitioned
into smaller slices that can be allocated
to specific VMs, or guests, via a standard
interface.
The Intel Ethernet X520 family of
adapters delivers the same functionality
and throughput as ten dual-port, one
gigabit adapters, saving cost, power, and
complexity. For more information on
virtualization please go to:

Unified Networking and Storage
The family of Intel Ethernet X520
adapters lowers your data center total
cost of ownership (TCO) by providing the
ability to route LAN and SAN traffic 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 X520 adapters offer
FCoE hardware acceleration to provide
performance comparable to FC HBAs. The
adapters support Data Center Bridging,
also known as Converged Enhanced
Ethernet (CEE), which enables customers
to configure traffic classes and priorities
to deliver a lossless Ethernet fabric.
An Intel Ethernet Converged Network
Adapter X520 reduces TCO by eliminating
redundant fabrics and saves the cost of
expensive FC HBAs and FC switch ports.
Support for iSCSI
The adapters provide complete 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 superior data
integrity.
The Intel Ethernet family of X520
adapters do it all: 10 Gigabit LAN, FCoE,
and iSCSI; truly delivering on the promise
of unified networking.
Reliable Performance
The family of X520 adapters includes a
number of advanced features that enable
it to provide industry-leading performance
and reliability.
Security Optimizations
The adapters support IPsec offload for
Microsoft’s* Network Access Protection
(NAP), Active Directory,* and future
security capabilities in Windows 7*. An
X520 adapter enables customers to run
a secure network environment without
sacrificing performance.
PCIe v2.0 (5 GT/s)
PCIe v2.0 (5 GT/s) support enables
customers to take full advantage of 10
GbE by providing a maximum of 20 Gbps
bi-directional throughput per port on a
single dual port card.
Designed For Multi-core Processors
Support for technologies such as
multiple queues, receive-side scaling,
multiple MSI-X vectors, and Low Latency
Interrupts enable the X520 adapters to
provide high-performance, 10 Gigabit
connectivity in multi-core server blades.
These technologies distribute network
processing across multiple CPU cores,
improving overall performance.
For today’s demanding virtualized data
center environments, the new family of
X520 adapters deliver ultimate flexibility
and scalability.
