Lenovo ThinkSystem DW612S System Configuration Manual

Chapter 1. IntroductionThe ThinkSystem DW612S Neptune DWC Solution 6U enclosure designed for high performance computing.This solution includes a single enclosure that can contain up to six ThinkSystem high-density servers, whichare designed to deliver a dense, scalable platform for distributed enterprise and hyperconverged.FeaturesPerformance, ease of use, reliability, and expansion capabilities were key considerations in the design ofyour solution. These design features make it possible for you to customize the system hardware to meet yourneeds today and provide flexible expansion capabilities for the future.Your solution implements the following features and technologies:• Features on DemandIf a Features on Demand feature is integrated in the solution or in an optional device that is installed in thesolution, you can purchase an activation key to activate the feature. For information about Features onDemand, see:https://fod.lenovo.com/lkms• Lenovo XClarity Controller (XCC)The Lenovo XClarity Controller is the common management controller for Lenovo ThinkSystem serverhardware. The Lenovo XClarity Controller consolidates multiple management functions in a single chip onthe server system board (system board assembly). Some of the features that are unique to the LenovoXClarity Controller are enhanced performance, higher-resolution remote video, and expanded securityoptions.The server supports Lenovo XClarity Controller 2 (XCC2). For additional information about Lenovo XClarityController 2 (XCC2), refer to https://sysmgt.lenovofiles.com/help/topic/lxcc_frontend/lxcc_overview.html.• UEFI-compliant server firmwareLenovo ThinkSystem firmware is Unified Extensible Firmware Interface (UEFI) compliant. UEFI replacesBIOS and defines a standard interface between the operating system, platform firmware, and externaldevices.Lenovo ThinkSystem solutions are capable of booting UEFI-compliant operating systems, BIOS-basedoperating systems, and BIOS-based adapters as well as UEFI-compliant adapters.Note: The solution does not support Disk Operating System (DOS).• Active MemoryThe Active Memory feature improves the reliability of memory through memory mirroring. Memorymirroring mode replicates and stores data on two pairs of DIMMs within two channels simultaneously. If afailure occurs, the memory controller switches from the primary pair of memory DIMMs to the backup pairof DIMMs.• Large system-memory capacityThe solution supports synchronous dynamic random-access memory (SDRAM) registered dual inlinememory modules (DIMMs) with error correcting code (ECC). For more information about the specific typesand maximum amount of memory, see “Technical Specifications” in the User Guide of each high-densityserver..• Integrated network support© Copyright Lenovo 2022 1
