Air cooling of processors

The SD535 V3 supports either a standard heatsink or high performance heatsink. The choice of heatsink is automatically selected based on the configuration of the server.

Table 11. Heatsinks
Feature code	Description
BWT7	1U CPU Heatsink
C640	1U CPU Heatsink (High Performance)

With air-cooled heatsinks, processors used in the SD535 V3 have the following thermal restrictions:

The following CPUs require a 25°C ambient temperature, and have limited drive and adapter support:
- AMD EPYC 9274F 24C 320W 4.05GHz Processor
- AMD EPYC 9374F 32C 320W 3.85GHz Processor
- AMD EPYC 9474F 48C 360W 3.6GHz Processor
The following CPUs are supported at a 25°C ambient temperature with limited drive and adapter support, however processor performance may be impacted:
- AMD EPYC 9184X 16C 320W 3.55GHz Processor
- AMD EPYC 9384X 32C 320W 3.1GHz Processor
500W processors (EPYC 9755 and EPYC 9965) are supported only with the following configuration:
- Base C63Y as listed in the SD535 V3 models section
- 2x NVMe drives maximum
- 12x 128GB DIMMs maximum
- 1x 2-port PCIe adapter
- 25°C ambient temperature required

For details about these processor requirements, and additional ambient temperature requirements, see the Operating environment section.

Lenovo Processor Neptune Core Module - Open-loop liquid cooling

The SD535 V3 also supports advanced direct-water cooling (DWC) capability with the Lenovo Processor Neptune Core Module. This module implements a liquid cooling solution where heat from the processors is removed from the rack and the data center using an open loop and coolant distribution units.

With the Processor Neptune Core Module, all heat generated by the processors is removed from the server using water. This means that the server fans and data center air conditioning units only need to remove the heat generated by the other components. This results in lower air conditioning costs and it enables the use of slower fans which results in lower overall power consumption.

The following figure shows the Lenovo Processor Neptune Core Module.

Lenovo Neptune Processor DWC Module
Figure 12. Lenovo Processor Neptune Core Module

The Processor Neptune Core Module also includes a leak detection module which can detect a leakage of more than 0.5ml (about 10 drops) along the length of the tube and then issue an event to the XClarity Controller. XCC will then post an error to the System Event Log and enable further actions. Once the liquid evaporates, a further event is issue to XCC.

The Processor Neptune Core Module is only available in CTO orders, not as a field upgrade. In the DCSC configurator, to select open-loop water cooling, select the Base feature code listed in the following table. The other necessary components will be automatically included by the configurator.

Configuration notes:

The Processor Neptune Core Module requires water infrastructure be available in the rack cabinet and data center, as described in the Water infrastructure section.
1, 2, 3 or 4 nodes can be installed in the D3 Chassis in a water-cooled configuraiton.
All processor SKUs are supported
All front drive bay configurations are supported
The use of the M.2 adapter is not supported as this space is occupied by the water hoses and drip sensor. The internal M.2 connectors at the front of the SD535 V3 are available.
The use of an internal (CFF) adapter is not supported as this space is occupied by the water hoses and drip sensor.
Only 1x USB port is offered at the rear of the server instead of two
Only 3x fans are supported (or needed)
The use of a cable management arm (CMA) is not supported

UEFI operating modes

The SD535 V3 offers preset operating modes that affect energy consumption and performance. These modes are a collection of predefined low-level UEFI settings that simplify the task of tuning the server to suit your business and workload requirements.

The following table lists the feature codes that allow you to specify the mode you wish to preset in the factory for CTO orders.

UK and EU customers: For compliance with the ERP Lot9 regulation, you should select feature BFYA. For some systems, you may not be able to make a selection, in which case, it will be automatically derived by the configurator.

Table 13. UEFI operating mode presets in DCSC
Feature code	Description
BFYA	Operating mode selection for: "Maximum Efficiency Mode"
BFYB	Operating mode selection for: "Maximum Performance Mode"

The preset modes for the SD535 V3 are as follows:

Maximum Efficiency Mode (feature BFYA): Maximizes performance/watt efficiency while maintaining reasonable performance
Maximum Performance Mode (feature BFYB): Achieves maximum performance but with higher power consumption and lower energy efficiency.

For details about these preset modes, and all other performance and power efficiency UEFI settings offered in the SD535 V3, see the paper "Tuning UEFI Settings for Performance and Energy Efficiency on AMD Processor-Based ThinkSystem Servers", available from https://lenovopress.lenovo.com/lp1267.

Encryption Enablement

For CTO orders, the configurator allows you to specify that you want to create an "encryption-ready" server, and to ensure that only components that support encryption are selectable in the configurator. This is done in DCSC and x-config configurator tools by selecting the feature code listed in the following table.

Table 23. Encryption Enablement
Part number	Feature code	Description
CTO only	CES1*	Drive Encryption Enablement (not supported with vSAN)

* In DCSC, this feature is in Storage > Internal Storage under the heading "Encryption Enablement"

Tip: This feature will not be selectable until an SED-capable drive is selected.

By selecting this feature code, the following requirements will be enabled in the configurator:

SED drives will be required
XCC2 Platinum will be required

Configuration notes:

Do not use this feature code for VMware vSAN or Nutanix servers, since these virtualization offerings do not support HW RAID adapter-based encryption
Selecting this feature code does not enable encryption at the factory
If you don't select this feature code, you will still be able to enable encryption in your server, however you will need to ensure that you have suitable storage controllers and drives installed in the server

Controllers for internal storage

The SD535 V3 offers the following connectivity options for internal drives:

Onboard SATA ports (feature AVUX)
Onboard NVMe ports (feature BC4V)
RAID adapter for SAS/SATA drives (PCIe slot-based)
Internal (CFF) RAID adapters for SAS/SATA drives (cabled in a dedicated space)

The following table lists the adapters used for the internal storage of the server.

Table 24. Controllers for internal storage

4Y37A72484	BJHM	ThinkSystem RAID 9350-8i 2GB Flash PCIe 12Gb Internal Adapter	1

Configuration notes:

The use of an Internal (CFF) adapter is mutually exclusive with an M.2 adapter since they share the same location and connections.
The internal (CFF) adapter is not supported in configurations with open-loop water cooling
For field upgrades to add an internal (CFF) adapter, the ThinkSystem SD535 V3 CFF RAID Card Cable Kit (4TA7A91033) is required. This kit includes the supercap holder needed for the 9350-8i RAID adapter. See the Internal storage section for details.

The onboard SATA controller has the following features:

Controller integrated into the AMD processor
JBOD only; no RAID support
Supports up to 6x SATA drives in the SD535 V3

The onboard NVMe support has the following features:

Controller integrated into the AMD processor
Supports up to 6x NVMe drives direct connected to onboard ports
Each drive has PCIe x4 host interface, up to PCIe Gen5 depending on the drive type

Flash storage adapters

The SD535 V3 does not support Flash storage adapters.

Cooling

Each SD535 V3 has has 4 simple-swap 40mm dual-rotor N+1 redundant fans which are used to cool all components. All fans are standard. The location of the fans is shown in in the Components and connectors section.

The SD535 V3 optionally open-loop water cooling of the processor with Lenovo Neptune Core water cooling. Water cooling is more efficient at removing heat from a server than traditional air cooling. With water cooling, only 3 fans are needed.

In addition to the system fans, each power supply has its own integrated fan.

There is no ordering information for the fans. All fans are included with the base system.

Power supplies

The D3 Chassis supports three redundant hot-swap power supplies. The power supply choices are listed in the following table.

Supported power supply configurations are the following, depending on the installed components:

3x power supplies: 2+1 without over-subscription (optionally, 1 power supply is redundant)
2x power supplies: 1+1 without over-subscription (optionally, 1 power supply is redundant)
1x power supply: No redundancy, without over-subscription (only supported with 2700W power supplies)

Power management is managed by the XCC2 service processor in one of the servers installed in the chassis (referred to as the "master node"). Management tasks include power supply sensor and fault reading, power policy, throttling in the event of a power supply failure, and power supply firmware updates. If the master node goes offline, another node in the chassis will automatically take on this role.

Tip: When configuring a server in the DCSC configurator, power consumption is calculated precisely by interfacing with Lenovo Capacity Planner. You can therefore select the appropriate power supply for your configuration. However, do consider future upgrades that may require additional power needs.

Lenovo XClarity One

Lenovo XClarity One is a cloud-native unified Management-as-a-Service (MaaS) platform, engineered to modernize IT infrastructure. .

XClarity One is the next milestone in Lenovo’s portfolio of systems management products. Now you can leverage the benefits of a true next-generation platform for the deployment, management, and maintenance of your infrastructure through a single, centralized platform that delivers a consistent user experience across all Lenovo products.

XClarity One's primary architectural value is divided into three key areas:

How it predicts issues (AI/Analytics)
How it securely connects (Secure Management Hubs),
How it actually configures the hardware at scale (Template-Driven Lifecycle Control)

AI-powered Automation

XClarity One harnesses the power of AI and predictive analytics to enhance the performance and reliability of your infrastructure with proactive protection.

AI-Powered Predictive Failure Analytics - XC1 utilizes machine learning infrastructure to look at live device telemetries. The platform securely collects memory-diagnostic logs and pushes them into an active MPFA AI model infrastructure to analyze health patterns and predict probable hardware degradation before it manifests as a hard failure.
AI-Powered Call-Home - A Call-Home serviceable event opens a support ticket automatically, leveraging AI technology (in the case of MPFA) for problem determination and fast resolution automatically dispatching parts and services, reducing service costs and minimizing downtime.

Secure Management Hub

Lenovo’s proprietary Management Hub is an on-premises virtual appliance that acts as the bridge between your infrastructure and the cloud.

On-Premises Security with Cloud Flexibility - your infrastructure has no direct connection to the cloud, greatly reducing your attack surface from external threats while still having the deployment benefits, flexibility, and scalability of a cloud solution.
Authentication and Authorization - built on a Zero Trust Architecture and requiring OTP Application authentication for all users to handle the support of all customers’ servers and client devices. Role-based access controls help define and restrict permissions based on user roles.

Template-Driven Lifecycle Control

Lenovo’s unified management model eliminates fragmented server administration, allowing you to deploy, track, and maintain your entire infrastructure fleet from a single cloud-native dashboard.

Automated Configuration and Compliance: Leverage scalable, repeatable device templates to rapidly deploy firmware updates, operating systems, and core baseboard management controller (BMC/UEFI) simultaneously across multiple sites. XClarity One continuously analyzes hardware compliance, shifting out-of-compliance systems to a critical status until a template re-deployment aligns them back to corporate standards.
Global Asset Visibility and Fleet Telemetry: Centralize real-time tracking of component health, warranty status, and comprehensive hardware inventories. The platform aggregates live usage data, including memory allocation, power consumption, and processor thermal trends, giving you total operational awareness whether a server resides in a centralized data center or a remote edge environment.

Centralized management via Lenovo XClarity One can be integrated into your environment as an optional component. License information for XClarity One is listed in the following table.

Platform Firmware Resiliency - Lenovo ThinkShield

Lenovo's ThinkShield Security is a transparent and comprehensive approach to security that extends to all dimensions of our data center products: from development, to supply chain, and through the entire product lifecycle.

The ThinkSystem SD535 V3 includes Platform Firmware Resiliency (PFR) hardware Root of Trust (RoT) which enables the system to be NIST SP800-193 compliant. This offering further enhances key platform subsystem protections against unauthorized firmware updates and corruption, to restore firmware to an integral state, and to closely monitor firmware for possible compromise from cyber-attacks.

PFR operates upon the following server components:

UEFI image – the low-level server firmware that connects the operating system to the server hardware
XCC image – the management “engine” software that controls and reports on the server status separate from the server operating system
FPGA image – the code that runs the server’s lowest level hardware controller on the motherboard

The Lenovo Platform Root of Trust Hardware performs the following three main functions:

Detection – Measures the firmware and updates for authenticity
Recovery – Recovers a corrupted image to a known-safe image
Protection – Monitors the system to ensure the known-good firmware is not maliciously written

These enhanced protection capabilities are implemented using a dedicated, discrete security processor whose implementation has been rigorously validated by leading third-party security firms. Security evaluation results and design details are available for customer review – providing unprecedented transparency and assurance.

The SD535 V3 includes support for Secure Boot, a UEFI firmware security feature developed by the UEFI Consortium that ensures only immutable and signed software are loaded during the boot time. The use of Secure Boot helps prevent malicious code from being loaded and helps prevent attacks, such as the installation of rootkits. Lenovo offers the capability to enable secure boot in the factory, to ensure end-to-end protection. Alternatively, Secure Boot can be left disabled in the factory, allowing the customer to enable it themselves at a later point, if desired.

The following table lists the relevant feature code(s).

Table 52. Secure Boot options
Part number	Feature code	Description	Purpose
CTO only	BPKQ	TPM 2.0 with Secure Boot	Configure the system in the factory with Secure Boot enabled.
CTO only	BPKR	TPM 2.0	Configure the system without Secure Boot enabled. Customers can enable Secure Boot later if desired.

Tip: If Secure Boot is not enabled in the factory, it can be enabled later by the customer. However once Secure Boot is enabled, it cannot be disabled.

Government regulations (such as those prescribed by OSHA or European Community Directives) may govern noise level exposure in the workplace and may apply to you and your server installation. The actual sound pressure levels in your installation depend upon a variety of factors, including the number of racks in the installation; the size, materials, and configuration of the room; the noise levels from other equipment; the room ambient temperature, and employee's location in relation to the equipment. Further, compliance with such government regulations depends on a variety of additional factors, including the duration of employees' exposure and whether employees wear hearing protection. Lenovo recommends that you consult with qualified experts in this field to determine whether you are in compliance with the applicable regulations.

Particulate contamination

Airborne particulates (including metal flakes or particles) and reactive gases acting alone or in combination with other environmental factors such as humidity or temperature might damage the system that might cause the system to malfunction or stop working altogether.

The following specifications indicate the limits of particulates that the system can tolerate:

Reactive gases:
- The copper reactivity level shall be less than 200 Angstroms per month (Å/month)
- The silver reactivity level shall be less than 200 Å/month
Airborne particulates:
- The room air should be continuously filtered with MERV 8 filters.
- Air entering a data center should be filtered with MERV 11 or preferably MERV 13 filters.
- The deliquescent relative humidity of the particulate contamination should be more than 60% RH
- Environment must be free of zinc whiskers

For additional information, see the Specifications section of the documentation for the server, available from the Lenovo Documents site, https://pubs.lenovo.com/

Lenovo Financial Services

Why wait to obtain the technology you need now? No payments for 90 days and predictable, low monthly payments make it easy to budget for your Lenovo solution.

Flexible
Our in-depth knowledge of the products, services and various market segments allows us to offer greater flexibility in structures, documentation and end of lease options.
100% Solution Financing
Financing your entire solution including hardware, software, and services, ensures more predictability in your project planning with fixed, manageable payments and low monthly payments.
Device as a Service (DaaS)
Leverage latest technology to advance your business. Customized solutions aligned to your needs. Flexibility to add equipment to support growth. Protect your technology with Lenovo's Premier Support service.
24/7 Asset management
Manage your financed solutions with electronic access to your lease documents, payment histories, invoices and asset information.
Fair Market Value (FMV) and $1 Purchase Option Leases
Maximize your purchasing power with our lowest cost option. An FMV lease offers lower monthly payments than loans or lease-to-own financing. Think of an FMV lease as a rental. You have the flexibility at the end of the lease term to return the equipment, continue leasing it, or purchase it for the fair market value. In a $1 Out Purchase Option lease, you own the equipment. It is a good option when you are confident you will use the equipment for an extended period beyond the finance term. Both lease types have merits depending on your needs. We can help you determine which option will best meet your technological and budgetary goals.

Ask your Lenovo Financial Services representative about this promotion and how to submit a credit application. For the majority of credit applicants, we have enough information to deliver an instant decision and send a notification within minutes.
