Supports the Gold and Platinum level processors in the Intel Xeon Processor Scalable Family, including the "top bin" highest-performing 205 W processors available from Intel. Offers a simple upgrade path that enables the server to be initially configured with as few as two processors and then later be upgraded to up to eight processors simply by adding a compute tray and system boards. Dense server offering where up to 8 processors and 96 DIMMs are housed in only 4U of rack space. Supports second-generation Intel Xeon Processor Scalable processors Intel Advanced Vector Extensions 512 (AVX-512) enable acceleration of enterprise-class workloads, including databases and enterprise resource planning (ERP). Intel Deep Learning Boost (Vector Neural Network Instruction set or VNNI) is designed to deliver significant, more efficient Deep Learning (Inference) acceleration for high-performance Artificial Intelligence (AI) workloads. Intel Speed Select Technology provides improvements in server utilization and guaranteed per-core performance service levels with more granular control over processor performance. Intel Virtualization Technology integrates hardware-level virtualization hooks that allow operating system vendors to better use the hardware for virtualization workloads. Intel Hyper-Threading Technology boosts performance for multithreaded applications by enabling simultaneous multithreading within each processor core, up to two threads per core. Intelligent and adaptive system performance with Intel Turbo Boost Technology 2.0 allows processor cores to run at maximum speeds during peak workloads by temporarily exceeding processor TDP.DCPMMs are up to 512 GB each, for a total of up to 24 TB of Persistent Memory. Supports the new Intel Optane DC Persistent Memory up to 48 Data Center Persistent Memory Modules (DCPMMs) can be installed in conjunction with regular system memory. Supports 2933 MHz Performance+ memory DIMMs which allow configurations of 2 DIMMs per channel to operate at the 2933 MHz rated memory speed.
Slim Upgrade Path ThatNew high-speed RAID controllers provide 12 Gb SAS connectivity to the drive backplanes. An SSD can support up to 100 times more I/O operations per second (IOPS) than a typical HDD. The use of solid-state drives (SSDs) instead of, or along with, mechanical hard disk drives (HDDs), can improve I/O performance. Of the 24x drive bays, support for up to 12 NVMe PCIe SSDs maximizes drive I/O performance, in terms of throughput, bandwidth, IOPS, and latency. Up to 24x 2.5-inch HDDs or SSDs provide a flexible and scalable all-in-one platform to meet your increasing demands. The server offers PCI Express 3.0 I/O expansion capabilities that improve the theoretical maximum bandwidth by almost 100% (8 GTps per link using 128b/130b encoding) compared to the previous generation of PCI Express 2.0 (5 GTps per link using 8b/10b encoding).The SR950 is based on a modular service model where all components and options can be removed from the front or rear of the system, even parts that are located in the center of the machine such as fans, memory DIMMs, and processors. In addition, the server has two internal slots for RAID or HBA adapters. A total of up to 17 rear-accessible PCIe slots: 14 general-purpose PCIe 3.0 slots plus slots dedicated to the LOM adapter and two ML2 adapters. The server has a dedicated flexible LAN-on-motherboard (LOM) slot offering a variety of 10 GbE or Gigabit Ethernet adapters that do not occupy one of the standard PCIe slots. Available M.2 adapters support either one M.2 drive, or two M.2 drives in a RAID 1 configuration, for the boot drive performance and reliability. Supports the Lenovo-patented M.2 adapter design for convenient operating system boot functions. The Dual M.2 Boot Adapter uses RAID-1 so that the two M.2 drives installed are configured as a redundant pair. The server offers hot-swap drives, supporting RAID redundancy for data protection and greater system uptime. The server offers Single Device Data Correction (SDDC, also known as Chipkill), Adaptive Double-Device Data Correction (ADDDC, also known as Redundant Bit Steering or RBS), memory mirroring, and memory rank sparing for redundancy in the event of a non-correctable memory failure. Three-year or one-year customer-replaceable unit and onsite limited warranty, 9 x 5 next business day. Support for the XClarity Administrator Mobile app running on a supported smartphone and connected to the server through the service-enabled USB port, enables additional local systems management functions. Auto-restart in the event of a momentary loss of AC power (based on power policy setting in the XClarity Controller service processor). Lenovo XClarity Provisioning Manager supports diagnostic functions and collects service data to USB key drive or remote CIFS share folder for troubleshooting, to reduce servicing time. Built-in diagnostics in UEFI, using Lenovo XClarity Provisioning Manager, speed up troubleshooting tasks to reduce service time. The built-in XClarity Controller continuously monitors system parameters, triggers alerts, and performs recovery actions in case of failures to minimize downtime. Mac system 7 emulator windowsXCC Enterprise is included as standard, which enables remote KVM and remote media files (ISO and IMG image files), boot capture, and power capping. The server includes an XClarity Controller (XCC) to monitor server availability and perform remote management.
