What the Xeon E5-2699R v4 is
The Xeon E5-2699R v4 brings Broadwell-EP to LGA 2011-v3 for embedded long life racks with DDR4. It launched in April 2016 with a 2.2 GHz base and up to 3.6 GHz boost at 145 W. Intel targets comms shelves that need 22 cores with extended supply.
Fifty five megabytes of Smart Cache carry guests and tables. The modest base clock fits 22 cores in 145 W. Forty four threads cover network loads plus agents.
There is no integrated GPU, so serial and network manage the node. The process is 14 nm. The multiplier is locked. DDR4-2400 with ECC in four channels feeds cores with up to 1.5 TB.
Buyers choose the board at order time with memory and drive tier. The 145 W rating needs 2U airflow. Two QPI links at 9.6 GT/s join paired sockets where nodes run 2S.
Socket and motherboard compatibility
The Xeon E5-2699R v4 fits LGA 2011-v3 on C612 server boards with DDR4 slots. Makers list Broadwell-EP with 2016 BIOS builds. Early stock may need an update.
Dual socket builds are supported with two QPI links. The R suffix marks embedded options with long supply. The Socket vs chipset: what decides whether a CPU works guide covers matching.
Rack nodes with one or two sockets are the deployment. Growth means more LGA 2011-v3 nodes. Power needs metered racks.
Memory, PCIe and cooling
DDR4-2400 with ECC in four channels suits comms hosts. Quad channel bandwidth helps packet work. Start with 256 GB for dense shelves.
PCIe 3.0 with 40 lanes per CPU serves HBAs and NICs. Boards split lanes between risers and NVMe. Chipset lanes add SATA and USB.
Cooling follows server practice with vendor heatsinks for 145 W classes. No cooler ships in the box. ECC guards memory.
Upgrade paths
On the same socket, the Intel Xeon E5-2699 v4 shares 2.2 GHz base with the same 22 cores for standard racks. The Intel Xeon E5-2699A v4 lifts to 2.4 GHz base for top shelves. Both share LGA 2011-v3 boards.
Twenty core E5-2698 v4 suits narrower hosts where listed. It needs the same boards.
Past embedded racks move to Skylake-SP. The E5-2699R v4 covers 2016 comms shelves where 22 cores with long supply must deploy.
