Designed for Multi-Core Processors
These
single-port Adapter provide high-performing, single-port Gigabit
connectivity in a multi-core platform as well as in a virtualized
environment. In a multi-core platform, the adapters support different
technologies such as multiple queues, receive-side scaling, MSI-X, and
Low Latency Interrupts, that help in accelerating the data across the
platform, thereby improving application response times.
The I/O
technologies on a multi-core platform make use of the multiple queues
and multiple interrupt vectors available on the network controller.
These queues and interrupt vectors help in load balancing the data and
interrupts amongst themselves in order to lower the load on the
processors and improve overall system performance. For example,
depending upon the latency sensitivity of the data, the low level
latency interrupts feature can bypass the time interval for specific TCP
ports or for flagged packets to give certain types of data streams the
least amount of latency to the application.
Optimized for Virtualization
The
NIC-9260PF-LX Single-Port Ethernet Adapter showcase the latest
virtualization technology called Intel Virtualization Technology for
Connectivity (IntelVT for Connectivity). IntelVT for Connectivity is a
suite of hardware assists that improve overall system performance by
lowering the I/O overhead in a virtualized environment. This optimizes
CPU usage, reduces system latency, and improves I/O through- put.
IntelVT for Connectivity includes:
- Virtual Machine Device Queues (VMDq)
- Intel I/O Acceleration Technology
Use
of multi-port adapters in a virtualized environment is very important
because of the need to provide redundancy and data connectivity for the
applications/workloads in the virtual machines. Due to slot limitations
and the need for redundancy and data connectivity, it is recommended
that a virtualized physical server needs at least six GbE ports to
satisfy the I/O requirement demands.
Virtual Machine Device queues (VMDq)
VMDq
reduces I/O overhead created by the hypervisor in a virtualized server
by performing data sorting and coalescing in the network silicon.2 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) get 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 NIC-9260PF-LX PCIe Gigabit adapter
provides improved performance with the next-generation VMDq technology,
which includes features such as loop back functionality for inter-VM
communication, priority-weighted bandwidth management, and doubling the
number of data queues per port from four to eight. It now also supports
multicast and broadcast data on a virtualized server.
Intel I/O Acceleration Technology
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 help to improve system performance
and application response times. The different features include multiple
queues and receive-side scaling, Direct Cache Access (DCA), MSI-X,
Low-Latency Interrupts, Receive Side Scaling (RSS), and others. Using
multiple queues and receive-side scaling, a DMA engine moves data using
the chipset instead of the CPU. DCA enables the adapter to pre-fetch
data from the memory cache, thereby avoiding cache misses and improving
application response times. MSI-X helps in load-balancing I/O interrupts
across multiple processor cores, and Low Latency Interrupts can provide
certain data streams a non-modulated path directly to the application.
RSS directs the interrupts to a specific processor core based on the
applications address.
