What the Xeon E5-2658 v4 is
The Xeon E5-2658 v4 brings Broadwell-EP to LGA 2011-v3 for balanced hosts with DDR4. It launched in March 2016 with a 2.3 GHz base and up to 2.8 GHz boost at 105 W. Intel targets virtual farms that need 14 cores with ECC at mid watts.
Thirty five megabytes of Smart Cache carry guests and tables. The steady base clock suits mixed tenants. Twenty eight threads cover VMs 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 105 W rating suits 2U shelves with shared airflow. Two QPI links at 9.6 GT/s join paired sockets where nodes run 2S.
Socket and motherboard compatibility
The Xeon E5-2658 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. Single socket nodes can also carry it where listed. 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 for 105 W per socket.
Memory, PCIe and cooling
DDR4-2400 with ECC in four channels suits virtual farms with many guests. Quad channel bandwidth helps live migration. Start with 128 GB for dense hosts.
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 105 W classes. No cooler ships in the box. Keep aisles clear. ECC guards memory.
Upgrade paths
On the same socket, the Intel Xeon E5-2660 v4 trims to 2.0 GHz base at the same 105 W for cooler aisles. The Intel Xeon E5-2680 v4 lifts to 2.4 GHz base at 120 W for faster racks. Both share LGA 2011-v3 boards.
Low power Intel Xeon E5-2650L v4 drops to 1.7 GHz base at 65 W for packed shelves. It needs the same boards.
Past balanced hosts move to Skylake-SP silver. The E5-2658 v4 covers 2016 farms where 14 cores with ECC must run at 105 W.
