Support for iSCSI
Intel® Ethernet server adapters with native iSCSI initiators built 
into Microsoft® Windows®, Linux®, and VMware® ESX platforms 
provide a simple, dependable, cost-effective way to connect 
to LANs and iSCSI SANs. These native initiators are broadly 
tested using multiple generations of operating systems, storage 
systems, and OS tools to help ensure reliability and ease of use. 
Standardizing on Intel Ethernet server adapters for iSCSI allows 
administrators to use a single initiator, TCP/IP stack, and set of 
management tools and IT policies. In addition, the I340 server 
adapter includes a number of hardware features designed to 
accelerate iSCSI traffic and enhance data processing. For example, 
TCP segmentation offload, Receive side coalescing (RSC), and 
checksum offload capabilities help reduce processor utilization, 
increase throughput, and deliver exceptional iSCSI performance. 
The adapters are designed to flexibly scale workloads across 
multi-core processor–based systems. Finally, using native OS 
initiators, an Intel® Ethernet I340 Server Adapter enables support 
for the CRC-32 digest instruction set included in the Intel® Xeon® 
processor 5500 series, which improves transmission reliablity and 
thus delivers an enterprise class iSCSI solution for the IT customer.
Optimized for Virtualization
The Intel® Ethernet I340 Server Adapter showcases a suite of 
hardware assists that improves overall system performance 
by lowering the I/O overhead in a virtualized environment. This 
optimizes CPU usage, reduces system latency, and improves I/O 
throughput. These features include:
• Virtual Machine Device Queues (VMDq)
• Intel® I/O Acceleration Technology (Intel® I/OAT)
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 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 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) 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.
Reliable Performance
The server adapter includes a number of advanced features that 
enable it to provide industry-leading quad-port 1GbE performance 
and reliability. With over 25 years of experience shipping Ethernet 
adapters, Intel offers unmatched quality and design.
PCIe* v2.0 (5 GT/s)
PCIe v2.0 (5 GT/s) support enables customers to take full 
advantage of the 1 GbE by providing a maximum of 2.0 Gbps 
bi-directional throughput per port on a single quad-port card.
For today’s demanding virtualized data center environments,  
the new Intel® Ethernet I340 Server Adapter delivers ultimate  
flexibility and scalability.
