Launch Date

The date the product was first introduced.

Expected Discontinuance

Expected Discontinuance is an estimate of when a product will begin the Product Discontinuance process. The Product Discontinuance Notification (PDN), published at the start of the discontinuance process, will include all EOL Key Milestone details. Some business units may communicate EOL timeline details before the PDN is published. Contact your Intel representative for information on EOL timelines and extended life options.

Lithography

Lithography refers to the semiconductor technology used to manufacture an integrated circuit, and is reported in nanometer (nm), indicative of the size of features built on the semiconductor.

TDP

Thermal Design Power (TDP) represents the average power, in watts, the processor dissipates when operating at Base Frequency with all cores active under an Intel-defined, high-complexity workload. Refer to Datasheet for thermal solution requirements.

Max Operating Temperature

This is the maximum operating temperature allowed as reported by temperature sensors. Instantaneous temperature may exceed this value for short durations. Note: Maximum observable temperature is configurable by system vendor and can be design specific.

Flexible Port Partitioning

Flexible Port Partitioning (FPP) technology utilizes industry standard PCI SIG SR-IOV to efficiently divide your physical Ethernet device into multiple virtual devices, providing Quality of Service by ensuring each process is assigned to a Virtual Function and is provided a fair share of the bandwidth.

Virtual Machine Device Queues (VMDq)

Virtual Machine Device Queues (VMDq) is a technology designed to offload some of the switching done in the VMM (Virtual Machine Monitor) to networking hardware specifically designed for this function. VMDq drastically reduces overhead associated with I/O switching in the VMM which greatly improves throughput and overall system performance

PCI-SIG* SR-IOV Capable

Single-Root I/O Virtualization (SR-IOV) involves natively (directly) sharing a single I/O resource between multiple virtual machines. SR-IOV provides a mechanism by which a Single Root Function (for example a single Ethernet Port) can appear to be multiple separate physical devices.

Fiber Channel over Ethernet

Fibre Channel over Ethernet (FCoE) is an encapsulation of Fibre Channel frames over Ethernet networks. This allows Fibre Channel to use 10 Gigabit Ethernet networks (or higher speeds) while preserving the Fibre Channel protocol.

MACsec IEEE 802.1 AE

802.1AE is the IEEE MAC Security (MACsec) standard which defines connectionless data confidentiality and integrity for media access independent protocols.

IEEE 1588

IEEE 1588, also knows as the Precision Time Protocol (PTP) is a protocol used to synchronize clocks throughout a computer network. On a local area network it achieves clock accuracy in the sub-microsecond range, making it suitable for measurement and control systems.

iWARP/RDMA

iWARP delivers converged, low-latency fabric services to data centers through Remote Direct Memory Access (RDMA) over Ethernet. The key iWARP components that deliver low-latency are Kernel Bypass, Direct Data Placement, and Transport Acceleration.

Intel® Ethernet Power Management

Intel® Ethernet Power Management Technology provides solutions to common power management approaches by reducing idle power, reducing capacity and power as a function of demand, operating at maximum energy efficiency whenever possible, and enabling functionality only when needed.

Intel® Data Direct I/O Technology

Intel® Data Direct I/O Technology is a platform technology that improves I/O data processing efficiency for data delivery and data consumption from I/O devices. With Intel DDIO, Intel® Server Adapters and controllers talk directly to the processor cache without a detour via system memory, reducing latency, increasing system I/O bandwidth, and reducing power consumption.
