What the Xeon E5-2650L v4 is
The Xeon E5-2650L v4 brings Broadwell-EP to LGA 2011-v3 for cool running racks with DDR4. It launched in March 2016 with a 1.7 GHz base and up to 2.5 GHz boost at 65 W. Intel targets packed shelves that need 14 cores with ECC at the lowest watts in class.
Thirty five megabytes of Smart Cache carry guests and tables. The low base clock fits 14 cores in 65 W. 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 with ECC in four channels feeds cores on Grantley boards.
Buyers choose the board at order time with memory and drive tier. The 65 W rating suits crowded racks. Two QPI links at 9.6 GT/s join paired sockets where nodes run 2S.
Socket and motherboard compatibility
The Xeon E5-2650L 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 65 W per socket.
Memory, PCIe and cooling
DDR4 with ECC in four channels suits dense hosts with many guests. Quad channel bandwidth helps live migration. Start with 128 GB for virtual 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 65 W classes. No cooler ships in the box. Keep aisles clear. ECC guards memory.
Upgrade paths
On the same socket, the Intel Xeon E5-2648L v4 gives 14 cores at 1.8 GHz base for slightly faster shelves at 75 W. The Intel Xeon E5-2658 v4 lifts to 2.3 GHz base at 105 W for faster hosts. Both share LGA 2011-v3 boards.
Mainstream Intel Xeon E5-2680 v4 gives 14 cores at 2.4 GHz for balanced racks. It needs the same boards.
Past low power racks move to Skylake-SP bronze. The E5-2650L v4 covers 2016 shelves where 14 cores with ECC must run at 65 W.
