Datasheet Volume Two: Functional Description, February 2014
MLC
Mid Level Cache
NCTF
Non-Critical to Function: NCTF locations are typically redundant ground or non-
critical reserved, so the loss of the solder joint continuity at end of life conditions
will not affect the overall product functionality.
NEBS
Network Equipment Building System. NEBS is the most common set of
environmental design guidelines applied to telecommunications equipment in the
United States.
PCH
Platform Controller Hub. The next generation chipset with centralized platform
capabilities including the main I/O interfaces along with display connectivity,
audio features, power management, manageability, security and storage
features.
PCU
Power Control Unit.
PCI Express 3.0
The third generation PCI Express specification that operates at 8 GT/s data
transfer rate per lane per direction. PCI Express 3.0 is completely backward
compatible with PCI Express 1.0 and 2.0.
PCI Express
PCI Express Generation 2.0/3.0
PCI Express 2.0
PCI Express Generation 2.0
PECI
Platform Environment Control Interface
Phit
Physical Unit. Data transfer unit of Intel
®
QPI Physical Layer. 1 Phit is equal to18
bits in ‘full width mode’ and 9 bits in ‘half width mode’.
Processor
The 64-bit, single-core or multi-core component (package)
Processor Core
A processing and execution unit which has an instruction cache, data cache, and
256-KB L2 cache. All processor cores share the LLC.
R3QPI
Ring to Intel
®
QPI agent interface. An internal logic block providing interface
between internal Ring and Intel
®
QPI Agents.
Rank
A unit of DRAM corresponding four to eight devices in parallel, ignoring ECC.
These devices are usually, but not always, mounted on a single side of a DDR3
DIMM.
RDIMM
Registered Dual In-line Memory Module
Scalable
Intel Xeon processor E7 v2 product family-platform targeted for scalable designs
using third party Node Controller chip. In these designs, Node Controller is used
to scale the design beyond one/two/four sockets.
SCI
System Control Interrupt. Used in ACPI protocol.
Server SKU
A processor Stock Keeping Unit (SKU) to be installed in either server or
workstation platforms. Electrical, power and thermal specifications for these
SKU’s are based on specific use condition assumptions. Server processors may
be further categorized as Efficient Performance server, workstation and HPC
SKUs. For further details on use condition assumptions, please refer to the latest
Product Release Qualification (PRQ) Report available via your Customer Quality
Engineer (CQE) contact.
SMBus
System Management Bus. A two-wire interface through which simple system and
power management related devices can communicate with the rest of the
system. It is based on the principals of the operation of the I
2
C* two-wire serial
bus from Philips Semiconductor.
Storage Conditions
A non-operational state. The processor may be installed in a platform, in a tray,
or loose. Processors may be sealed in packaging or exposed to free air. Under
these conditions, processor landings should not be connected to any supply
voltages, have any I/Os biased or receive any clocks. Upon exposure to “free air”
(that is, unsealed packaging or a device removed from packaging material) the
processor must be handled in accordance with moisture sensitivity labeling
(MSL) as indicated on the packaging material.
TAC
Thermal Averaging Constant
TDP
