− | + | Skylake-based servers have been entirely re-architected to meet the need for increased scalabiltiy and performance all while meeting power requirements. A superset model is shown on the right. Skylake-based servers are the first mainstream servers to make use of Intel's new mesh interconnect architecture, an architecture that was previously explored, experimented with, and enhanced with Intel's {{intel|Phi}} [[many-core processors]]. Those processors are offered from [[4 cores]] up to [[28 cores]] with 8 to 56 threads. With Skylake, Intel now has a separate core architecture for those chips which incorporate a plethora of new technologies and features including support for the new {{x86|AVX-512}} instruction set extension. | |
− | + | All models incorporate 6 channels of DDR4 supporting up to 12 DIMMS for a total of 768 GiB (with extended models support 1.5 TiB). For I/O all models incorporate 48x (3x16) lanes of PCIe 3.0. There is an additional x4 lanes PCIe 3.0 reserved exclusively for DMI for the the {{intel|Lewisburg|l=chipset}} chipset. For a selected number of models (specifically those with ''F'' suffix) have an {{intel|Omni-Path}} Host Fabric Interface (HFI) on-package (see [[#Integrated_Omni-Path|Integrated Omni-Path]]). | |
− | + | Skylake processors are designed for scalability, supporting 2-way, 4-way, and 8-way multiprocessing through Intel's new {{intel|Ultra Path Interconnect}} (UPI) interconnect links, with two to three links being offered (see [[#Scalability|§ Scalability]]). High-end models have node controller support allowing higher way (e.g., 32-way multiprocessing). | |
