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.

• 6x RDIMMs and 1x persistent memory module
• 8x RDIMMs and 1x persistent memory module
• 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.

The SE450 offers the following internal storage options:

• Up to 4x internal SSD drive bays supporting non-hot-swap trayless NVMe or SATA SSD drives

• Up to 4x 7mm trayless drives, either SATA or NVMe (zero drives also supported)
• Up to 2x 15mm trayless drives, either SATA or NVMe (zero drives also supported)

The internal drive cage is mounted at the front of the processor and DIMMs as shown in the following figure.

Figure 7. Location of the internal drive cage

The internal drive cage, feature BMGT, is a standard feature in all configurations, however the bays are only usable provided the cables are also installed, either CTO (NVMe or SATA cabling) or as a field upgrade (SATA cabling only).

The SE450 supports field upgrades to enable SATA drives in the internal drive cage. The following part numbers are available for cables.

Hot-swap drive bays

The SE450 supports 2x 2.5-inch hot-swap drive bays, mounted in place of Riser 2.

Figure 8. Location of the hot-swap drive bays

The drive cage is only available in preconfigured models or CTO. Field upgrades are not available.

Configuration requirements:

• The hot-swap drive bays support 2.5-inch hot-swap drives, either SATA, NVMe or SAS. SAS drives require the use of a RAID adapter or SAS HBA.
• The hot-swap drive bays are mutually exclusive with Riser 2 (slots 3 and 4)
• The server supports a maximum of 4x NVMe drives, so if two NVMe drives are configured as hot-swap drives, then only two NVMe drives can be configured in the internal drive cage (trayless drives)
• The required cables are derived by the configurator; SATA and NVMe cables are configured based on the controller selected even if no drives are selected in DCSC.

For configurations with onboard SATA, it is supported to upgrade the controller to a RAID adapter or HBA. To do so, order the adapter as well as the RAID cable listed in the following table, 4X97A90160. Similarly, to remove a RAID adapter or HBA and reconfigure the server to use the onboard SATA controller instead, order the SATA cable listed, 4X97A90163.

The server has a dedicated OCP 3.0 SFF slot with PCIe 4.0 x16 host interface. See Figure 3 for the location of the OCP slot. One port can optionally be shared with the XCC management processor for Wake-on-LAN and NC-SI support.

The following table lists the supported OCP adapters. These adapters are CTO only and not available as field upgrades.

The following table lists additional supported network adapters that can be installed in the regular PCIe slots. All adapters are supported in both 300mm and 360mm chassis.

For more information, including the transceivers and cables that each adapter supports, see the list of Lenovo Press Product Guides in the Networking adapters category:
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:

• The Controlled GPU column indicates the required CTO model. See the Models section for information.
  • Controlled GPUs require CTO model 7D8TCTOAWW. This CTO model is not available in some markets.
  • GPUs that are not controlled require CTO model 7D8TCTO1WW.
• GPUs that require the 360mm chassis must use Base feature code BMHC. See the Models section for information.
• Installed GPUs must be identical
• Full-length GPUs such as the Intel Flex 170, NVIDIA L40, A30, and A40 are only supported with the following processors, and only with 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
• Configuration requirements when selecting the Intel Flex 170 GPU:
  • The Flex 170 is only supported in 360mm configuration #3, as described in the Configurations section
  • The Flex 170 is only supported in slot 3 or slot 6 with a PCIe x16 host interface
  • A maximum of 2x internal NVMe drives is supported
• When the NVIDIA A40 GPU is installed, the maximum ambient temperature is 40°C (104°F).
• The use of the double-wide GPUs requires an auxiliary power cable as listed in the following table. For CTO orders, power cables are automatically derived by the configurator.

• 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.

For information about the GPU, see the ThinkSystem GPU Summary, available at:

LXEM is a licensed product. A single-node LXEM license is included with the XClarity Controller Enterprise upgrade as described in the Remote Management section. If your server does not have the XCC Enterprise upgrade, Energy Manager licenses can be ordered as shown in the following table.

Topics in this section:

• Security features
• Intrusion switch
• Firmware and TPM 2.0 Security Module
• Security bezel
• Security Pack
• Intel Transparent Supply Chain

Security features

The SE450 offers a number of security features, both electronic and physical.

Physical security features:

• Intrusion detection (optional, CTO only).
• Front security bezel with key lock (optional, available as a field upgrade, but requires the bezel detect module added in the factory)
• EIA mounting flange with security key (optional, CTO only)

  Available EIA bracket that uses a security screw to attach the server to the front flange of the rack cabinet. See EIA bracket with security screw for more information.

Electronic security features include:

• Automatic actions on tamper detection

  In the event of an intrusion or movement, the server can be configured in XCC to perform actions, including server shutdown and disabling remote access to the XCC from the network ports (referred to as the BMC network bridge).

• Self-encrypting (SED) drives that ensure data is secured when the drives are powered off
• Administrator password and a power-on password in UEFI
• Trusted Platform Module (TPM) supporting TPM 2.0, implemented on a mezzanine card, enables advanced cryptographic functionality in the operating system and applications. (not available for customers in PRC)
• Optional support for a secure manufacturing supply chain using Intel Transparent Supply Chain

The server is NIST SP 800-147B compliant.

The intrusion switch is optional but is only available via CTO orders, not as a field upgrade. See the Internal view of the server for the location of this component.

Ordering information is listed in the following table.

The following figure shows the SE450 with security bezel installed.

Figure 13. SE450 with security bezel installed

The security bezel is only available as an option part number and cannot be ordered as part of a CTO order, however the security bezel requires the security bezel detect module in order for the bezel to be recognized as installed by the server and for the LEDs on the security bezel to function. The security bezel detect module is only available CTO by selecting feature BR1K in DCSC.

The security bezel also duplicates the system LEDs. The layout of the LEDs is identical to the LED grouping on top of the server. See the Local management section for information about the LEDs.

The security bezel also supports the installation of a dust filter as described in the Operating environment section.

Security Pack

The Security Pack is the collection of security and activation features of the SE450:

• 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).

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

• 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.
