Lenovo ThinkEdge SE450 Edge Server

The Lenovo ThinkEdge SE450 is a single-socket server, with a 2U height and short depth case that can go almost anywhere. It can be mounted on a wall, placed on the floor like a tower server, or mounted in a rack. This rugged edge server can handle continuous operating temperatures from 5°C and 45°C; and some configurations are designed to meet NEBS Level-3 and ETSI requirements for 96 hours operating excursions from -5°C and 55°C as well as tolerance to locations with high-dust and vibration.

The ThinkEdge SE450 is based on the 3rd Gen Intel Xeon Scalable processor and is designed to virtualize traditional IT applications as well as new transformative AI systems, providing the processing power, storage, accelerator, and networking technologies required for today’s edge workloads. Lenovo’s innovation makes the ThinkEdge SE450 one of the most powerful, yet quiet servers on the market, allowing it to be deployed next to end users without disturbing the workplace.

Figure 1. Lenovo ThinkEdge SE450

Customers with remote locations have had to make a choice between underpowered IOT gateways and PCs, or overpowered and non-rugged data center servers. With the SE450, now they have an option: a compact edge server designed specifically to meet the needs of remote locations with the processing power to run AI workloads.

The ThinkEdge SE450 is a purpose-built server that is significantly shorter than a traditional server, making it ideal for deployment in tight spaces. It can be mounted on a wall, placed vertically in a floor stand, or mounted in a rack.

The ThinkEdge SE450 puts increased processing power, storage and network closer to where data is generated, allowing actions resulting from the analysis of that data to take place more quickly. The server is also designed for Wireless LAN (WLAN) connectivity for even great flexibility in deployment options.

Since these edge servers are typically deployed outside of secure data centers, they include technology that encrypts the data stored on the device if it is tampered with, only enabling authorized users to access it.

• 4x RDIMMs and 4x persistent memory modules

The  processor has 4 memory controllers and 8 memory channels; with all-memory configurations (that is, without persistent memory), the DIMMs are installed 1 RDIMM per channel. This corresponds to all the white DIMM slots on the system board. See the internal view of the server for the location of the DIMM slots.

Lenovo TruDDR4 RDIMMs and 3DS RDIMMs are supported. With 8x 128 GB 3DS RDIMMs installed, the SE450 supports a total of 1 TB of system memory.

The use of persistent memory is described in the Persistent Memory section.

Memory operates at up to 3200 MHz, depending on the processor selected. If the processor selected has a lower memory bus speed, then all DIMMs will operate at that lower speed. See the Processor features section for details.

Lenovo TruDDR4 memory uses the highest quality components that are sourced from Tier 1 DRAM suppliers and only memory that meets the strict requirements of Lenovo is selected. It is compatibility tested and tuned to maximize performance and reliability. From a service and support standpoint, Lenovo TruDDR4 memory automatically assumes the system warranty, and Lenovo provides service and support worldwide.

The following table lists the memory options that are available for the server.

For best performance, consider the following:

• Install 8 memory DIMMs so that all memory channels are used.
• Populate memory channels so they all have the same total memory capacity.
• Ensure all memory controllers on a processor socket have the same DIMM configuration.

Note: Memory sparing is not supported

If memory channel mirroring is used, then DIMMs must be installed in pairs or sets of three (minimum of one pair or set of three), and all DIMMs in the pair or set of three must be identical in type and size. 50% of the installed capacity is available to the operating system.

https://lenovopress.com/servers/options/ethernet

The following table lists the supported GPUs. The use of full-length GPUs requires the 360mm chassis - see Models for ordering information.

Configuration notes:

• Some NVIDIA A Series GPUs are available as two feature codes, one with a CEC chip and one without a CEC chip (ones without the CEC chip have "w/o CEC" in the name). The CEC is a secondary Hardware Root of Trust (RoT) module that provides an additional layer of security, which can be used by customers who have high regulatory requirements or high security standards. NVIDIA uses a multi-layered security model and hence the protection offered by the primary Root of Trust embedded in the GPU is expected to be sufficient for most customers. The CEC defeatured products still offer Secure Boot, Secure Firmware Update, Firmware Rollback Protection, and In-Band Firmware Update Disable. Specifically, without the CEC chip, the GPU does not support Key Revocation or Firmware Attestation. CEC and non-CEC GPUs of the same type of GPU can be mixed in field upgrades.

• Installed GPUs must be identical
• Full-length GPUs such as the NVIDIA A30 and A40 are only supported with the following processors that have a 1U heatsink:
  • Intel Xeon Gold 6330N
  • Intel Xeon Gold 5318N
  • Intel Xeon Gold 5317
  • Intel Xeon Silver 4316
  • Intel Xeon Silver 4314
  • Intel Xeon Silver 4310T
• When the NVIDIA A40 GPU is installed, the maximum ambient temperature is 40°C (104°F).
• The use of the NVIDIA A30 and A40 GPUs requires an auxiliary power cable as listed in the following table.

For information about the GPU, see the ThinkSystem GPU Summary, available at:
https://lenovopress.com/lp0768-thinksystem-thinkagile-gpu-summary

The SE450 server has six 60 mm dual-rotor simple-swap fans.

All six are standard and support N+1 rotor redundancy.

The SE450 supports one or two hot-swap power supplies, installed at the front of the server. When two are installed, they are redundant in most configurations. Ordering information is listed in the following table.

Power supply LEDs

The supported hot-swap power supplies have the following LEDs:

• Power input LED: 
  • Green: The power supply is connected to the AC power source
  • Off: The power supply is disconnected from the AC power source or a power problem has occurred
• Power output LED:
  • Green: The server is on and the power supply is working normally
  • Blinking green: The power supply is in Zero-output/Standby mode (see below)
  • Off: The server is powered off, or the power supply is not working properly
• Power supply error LED:
  • Off: The power supply is working normally
  • Yellow: The power supply has failed

Zero-output mode: When Zero-output mode (also known as Standby mode or Cold Redundancy mode) is configured in XCC and the server power load is sufficiently low, one of the installed power supplies enters into the Standby state while the other one delivers entire load. When the power load increases, the standby power supply will switch to Active state to provide sufficient power to the server. Zero-output mode can be enabled or disabled in the XClarity Controller web interface, Server Configuration > Power Policy. If you select Disable, then both power supplies will be in the Active state.

-48V DC power cord

For the -48V DC Power Supply, the following power cable is supported.

• Enablement of local Self-encrypting (SED) authentication key (AK) management
• Mandatory claiming and activation process to identify the owner of SE450 when the server is first delivered/powered on

To enable the Security Pack features, select feature BLZ2. If you do not wish to have the features of the Security Pack enabled in the SE450, it can be physically removed from the system board by using feature BU0C.

Notes:

• The Security Pack features setting cannot be changed after the system leaves the factory. For example, if you select feature BLZ2 to enable the Security Pack features, then the system will require activation before it can be first used. Similarly, if your system was configured with the Security Pack depopulated (physically removed from the system board), it cannot later be added.
• Customers can use the ThinkShield Portal to determine which of their systems have Security Pack enabled or disabled (you will see "Standard" if the system has Security Pack disabled).

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 ThinkEdge SE450 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 SE450 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 feature code to enable secure boot in the factory, or to leave it disabled.

The SE450 server can be installed in a rack cabinet, either 2-post, 4-post long, or 4-post short.

In this section:

• Rail kits
• EIA bracket with security screw
• EIA bracket adjustment

Rail kits

The following table lists the available rail kits. Each kit includes the left and right rails plus mounting hardware.

The following table summarizes the specifications of the available rail kits

EIA bracket with security screw

The SE450 offers two types of EIA brackets (also known as ear brackets or ears):

• Standard EIA bracket - uses thumbscrews to secure the server to the front flange of the cabinet
• Security EIA bracket - uses security screws and key to secure the server to the front flange of the cabinet

The use of the security bracket and key (the key is included with the brackets) aids in preventing unauthorized personnel from removing the server from the rack.

The following figure shows the two EIA bracket types.

Figure 14. EIA brackets for the SE450

Ordering information is listed in the following table.

EIA bracket adjustment

When installed in a rack cabinet, the EIA brackets on either side of the  SE450 chassis can be adjusted to best fit the front cabling and clearance needs of your environment. The EIA brackets can be in one of six different positions as shown in the following figure.

Position 1 locates the server as far back into the rack cabinet as possible, such that the front of the security bezel is flush with the front flange of the cabinet. The distance between positions 1, 2, 3, 4, and 5 is 12.5 mm. Position 6 positions the server as far forward as possible, and is an additional 37.5 mm from position 5, for a total of 100 mm difference between positions 1 and 6.
