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 SE455 V3, 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 SE455 V3 is a purpose-built server that is significantly shorter than a traditional server, making it ideal for deployment in tight spaces. The ThinkEdge SE455 V3 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.

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

Scalability and performance

The SE455 V3 offers numerous features to boost performance, improve scalability and reduce costs: 

• Support for a single processor from the powerful AMD EPYC 8004 ("Siena") processor family, designed to optimize "performance per watt"

Heatsink

For factory orders, the SE455 V3 supports either a 1U or 2U processor heatsink, as listed in the following table. Field upgrades are not supported.

The 2U heatsink is recommended to maximize heat dissipation and minimize fan noise, and is the default selection in the DCSC configurator.

The 1U heatsink is required for full-length adapters, however it does have the following requirements:

• Processor with TDP ≤ 130W
• Ambient temperature ≤ 45°C

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

The preset modes for the SE455 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.

Configuration notes:

• If either acoustic mode is selected in the DCSC configurator, Maximum Performance Mode (feature BFYB) is not available. For more information about the acoustic modes, see the Acoustic modes section

The SE455 V3 uses Lenovo TruDDR5 memory operating at up to 4800 MHz. The server supports 6 DIMMs. The processor has 6 memory channels and supports 1 DIMM per channel.

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

Lenovo TruDDR5 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 TruDDR5 memory automatically assumes the system warranty, and Lenovo provides service and support worldwide.

• The server supports quantities 1, 2, 4, or 6 DIMMs; other quantities not supported
• Mixing not supported:
  • Mixing 16Gb, 24Gb and 32Gb DIMMs is not supported (see the column in the above table)
  • Mixing x4 and x8 is not supported (see the descriptions of the DIMMs)
• Mixing of DIMM rank counts (1R, 2R) is supported, provided the above mixing rules are met. Follow the required installation order installing the DIMMs with the higher rank counts first.

In this section:

• Front hot-swap drive bays
• Internal drive bays
• Supported drive bay combinations
• Storage field upgrades
• M.2 drives
• RAID flash power module (supercap) support

Front hot-swap drive bays

The SE455 V3 supports 4x 2.5-inch hot-swap drive bays at the front of the server, using the backplanes listed in the following table.

Configuration requirements:

• Front drive bays are standard in all configurations of the SE455 V3 and cannot be deselected
• Drives supported are either SATA or NVMe, depending on the backplane selected.
• NVMe drives have a PCIe Gen 4 connection
• SAS drives are currently not supported (once supported, the use of SAS drives require a RAID adapter or SAS HBA)

Internal drive bays

The SE455 V3 supports 4x 2.5-inch drive bays internal to the server on the right side as shown in the figure above.

The drives are installed in a cage that rotates up for easy access, and are mounted with hot-swap drive trays, however they are not considered hot-swap. This is because the SE455 V3 does not support in-rack servicing, which means that the server must be powered off and removed from the rack before the top cover can be opened.

The backplanes for the internal drive bays are listed in the following table.

Configuration requirements:

• Internal drive bays are optional.
• Drives supported are either SATA or NVMe, depending on the backplane selected.
• NVMe drives have a PCIe Gen 4 connection
• The front and internal backplanes can be different (they don't both have to be SATA backplanes for example).
• SAS drives are currently not supported (once supported, the use of SAS drives require a RAID adapter or SAS HBA).
• PCIe slots 6 & 8 of Riser 2 share one of the onboard NVMe ports used by the drive bays. As a result, If the internal drive bays are NVMe and the front drives are connected to onboard SATA or NVMe, then slots 6 and 8 in Riser 2 are not connected. Slot 7 is still available, however. See the Configurations section for specifics.

Supported drive bay combinations

The following table lists the supported drive bay combinations.

Storage field upgrades

The following field upgrades are supported:

• Convert a configuration from an onboard controller to a RAID adapter or SAS HBA

The SE455 V3 supports the adding either M.2 adapter as a field upgrade.

The following table lists the part numbers needed to add the ThinkSystem M.2 SATA/x4 NVMe 2-Bay Adapter (4Y37A79663) as a field upgrade. Note that 4XF7A89291 does not include the M.2 adapter; you will need to order 4Y37A79663 as well.

The following table lists the part numbers needed to add the ThinkSystem M.2 RAID B540i-2i SATA/NVMe Adapter (4Y37A90063) as a field upgrade. A separate RAID adapter is not required nor supported.

For further details about M.2 components, see the ThinkSystem M.2 Drives and M.2 Adapters product guide:
https://lenovopress.com/lp0769-thinksystem-m2-drives-adapters

RAID flash power module (supercap) support

If you plan to add a RAID 940 adapters as a field upgrade, then you will also need to order a separate cable kit. This kit provides a cable of suitable length to connect the RAID adapter's flash power module (supercap) to the RAID adapter.

For CTO orders, the components in the installation kit are automatically derived when you select the RAID adapter.

The supercap is installed in a dedicated location adjacent to the M.2 adapter as shown in the internal view of the server.

Ordering information for the cable kit is listed in the following table. The supercap itself is included with the adapter and does not need to be ordered separately.

The drives of the SE455 V3 are connected to controller on the system board:

• Onboard SATA ports (no RAID support)
• Onboard NVMe ports (no RAID support)

The following table lists the controllers that can also be used for the internal storage of the server.

Configuration rules:

• Only one SATA controller (onboard or RAID adapter or HBA) can be selected. It it not supported to have one controller for the internal drives and a separate controller for the hot-swap drives.

The following tables list the drive options for internal storage of the server.

The SE455 V3 does not support an optical drive.

The SE455 V3 has up to six full-height (FH) PCIe slots for adapters, plus an OCP 3.0 slot. Slots are half-length (FHHL) by default, unless a full-length (FHFL) adapter is selected in the configurator.

• Riser 1:
  • Slot 3: PCIe Gen5 x16
  • Slot 4: PCIe Gen4 x8
  • Slot 5: PCIe Gen4 x8
• Riser 2 (optional)
  • Slot 6: PCIe Gen4 x8 (not connected in some configurations)
  • Slot 7: PCIe Gen5 x16
  • Slot 8: PCIe Gen4 x8 (not connected in some configurations)
• OCP slot 9: PCIe G5 x16

Specific support for these slots is listed in the Configurations section.

Figure 9. Slot numbering

Ordering information for the Risers are listed in the following table. Riser 1 is standard in all configuration, but Riser 2 is optional and can also be added as a field upgrade.

Configurations notes:

• Risers are configured in the factory to support either full-length (FL) adapters or half-length (HL) adapters, based on the adapters selected. Air baffles and cages are derived by the configurator based on whether the adapters are FL or HL to ensure proper airflow and adapter support. For CTO factory orders:
  • Risers with only HL adapters or without any adapters installed will be configured to only support HL adapters
  • Risers with a FL adapter installed will be configured to support FL adapters or a mix of FL and HL adapters
• The use of full-length (FL) adapters requires full-length slots and the processor must have a 1U heatsink; a 2U heatsink is not supported as the FL adapter and 2U heatsink occupy the same physical space.
• If a riser is configured to support FL adapters then it is the upper two slots that support FL adapters (slots 3 & 4 in Riser 1, slots 6 & 7 in Riser 2). The lower slot in each riser (slot 5 and slot 9) will be a HL slot due to physical interference of the 1U heatsink and other components.

Slot field upgrades

The risers in the SE455 V3 are configured in one of two ways, depending on the factory configuration:

• Support for half-length adapters only (includes low profile): All three slots in the riser will only support half-length adapters. This is the default configuration, and is used if no adapters are configured or if only half-length adapters are configured.
• Support for full-length adapters: The top two slots will support full-length (FHFL) adapters; the bottom slot will only support half-length adapters. Risers will only be configured this way if an adapter in the factory order is a full-length adapter (eg double-wide GPU).

If you wish to convert a server from full-length to half-length or from half-length to full-length, then you will need to order the kit listed in the following table.

Upgrade notes:

• The server only supports FL adapters provided the CPU has a 1U heatsink attached. If a 2U heatsink is used, then the server cannot support an upgrade to FL adapters.
• If Riser 2 is not present, and you wish to add Riser 2 with FL adapter support (eg to add support for a second DW GPU), you will only need to order ThinkEdge SE455 V3 Riser2 Kit, 4XF7A89287. The ThinkEdge SE455 V3 Full Length Adapter Enablement Kit (4XF7A89286) is not required as 4XF7A89287 includes the needed components for FL adapters. For GPUs, you may also need to order a GPU auxiliary power cable as described in the GPU adapters section.

If you remove a PCIe adapter or an OCP adapter, you should replace them with a slot filler to ensure the correct airflow is maintained. Ordering details are listed in the following table.

The SE455 V3 has a dedicated OCP 3.0 SFF slot with PCIe 5.0 x16 host interface. 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.

The following table lists additional supported network adapters that can be installed in the PCIe slots.

Configuration rules:

• For CTO orders, the quantity of Ethernet and InfiniBand cables is limited as follows, due to space limitations in the server packaging. Additional cables can be ordered separately using part numbers.
  • With the security bezel included in the order, at most 2x cables (power cords or network cables) can be included in the CTO order
  • If the security bezel is not included in the order, at most 4x cables (power cords or network cables) can be included in the CTO order
  • No cables 10m or longer can be included in the CTO order and will need to be ordered separately as part numbers.

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 Fibre Channel HBAs supported by the SE455 V3.

The SE455 V3 supports the accelerators listed in the following table.

The following table lists the supported GPUs.

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
• The use of the NVIDIA L40 or L40S GPU may require 1800W power supplies, depending on the configuration
• The use of the NVIDIA L40 or L40S GPU requires:
  • 1U heatsink
  • Processor with TDP ≤ 130W
  • Ambient temperature ≤ 40°C - see Operating environment section
  • No acoustic mode selected in the configurator - see Acoustic modes section

You will need these two options if you are adding 1x or 2x L40 or L40S GPUs, including if you are adding a second L40 or L40S GPU to a server that already has one L40 or L40S installed in the factory.

If you have Riser 2 installed and only plan to install 1x L40 or L40S GPU, install it in Riser 2 (slot 7) to optimize thermal and acoustic performance.

For two GPUs, you will also need to order the Riser 2 kit, if the server doesn't already have Riser 2 installed. See the I/O expansion section.

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

The SE455 V3 server has five 60 mm dual-rotor simple-swap fans.

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 SE455 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 SE455 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).

System Lockdown Mode

System Lockdown Mode is an optional security feature of the SE455 V3 that ensures that the system is only used by its intended recipient and that all data and applications remains secure.

System Lockdown Mode is an optional feature that can be remotely managed in two ways:

• ThinkShield Key Vault Portal Managed. This provides a centralised remote management approach, allowing the administrator to remotely managed multiple systems and to register ownership of systems to their company, which reduces the system’s value if stolen.
• XClarity Controller Managed. This provides remote management level control to an individual system using XCC web interface, OneCLI or Redfish.

To select ThinkShield Key Vault Portal Managed in factory orders, select feature BYBR, as listed in the following table. The default in DCSC is to select XClarity Controller Managed, feature BYBQ.

If System Lockdown is enabled in the factory, the system will be delivered in system lockdown mode and will require activation before operation. There are three ways the server can be activated:

• Using a mobile device (iOS or Android) connect to the server to the USB management port on the front of the server and running the ThinkShield Edge Mobile Management app.
• Connecting the system to the Internet via the XCC management port on the front of the server and accessing the ThinkShield Key Vault Portal from a web browser on another system.
• In a disconnected mode, where neither a mobile device or an internet connection to the SE455 V3 are available.

For more information, see ThinkEdge Security, available from:
https://lenovopress.lenovo.com/lp1725-thinkedge-security

The SE455 V3 offers a Security LED that indicates the status of the server:

• LED on: Security is enabled; System is operational.
• LED blinking: Security is enabled and the server is in lockdown, either due to being delivered from the factory in lockdown mode or has entered lockdown as a result of a tamper event. System must be activated or reactivated before becoming operational.
• LED off: Security is disabled; System is operational.

SED encryption in factory orders

The SE455 V3 also optionally supports enabling SED drive encryption in the factory using feature BYBS as listed in the following table. This feature enables SED on the selected drives and sets and SED Authentication Key (SED AK).

If SED drive encryption is disabled in factory, it is possible to enable it later in XClarity Controller. Note that it is not possible to disable drive encryption once it has been enabled.

AMD Infinity Guard

The SE455 V3 implements the following security features enabled in the AMD EPYC processor:

• Secure Memory Encryption

  Helps protect against attacks on the integrity of main memory (such as cold-boot attacks) because it encrypts the data. High-performance encryption engines integrated into the memory channels help speed performance. All of this is accomplished without modifications to your application software.

• Secure Encrypted Virtualization

  Helps safeguard privacy and integrity by encrypting each virtual machine with one of up to 509 unique encryption keys known only to the processor. This aids in protecting confidentiality of your data even if a malicious virtual machine finds a way into your virtual machine’s memory, or a compromised hypervisor reaches into a guest virtual machine.

• Secure Nested Paging

  Adds strong memory integrity protection capabilities to help prevent malicious hypervisor based attacks like data replay, memory re-mapping, and more in order to create an isolated execution environment.

• Secure Boot

  Mitigates against firmware-level attacks, Extends the AMD silicon root of trust to help protect the system BIOS. This helps the system establish an unbroken chain of trust from the AMD silicon root of trust to the BIOS using AMD Secure Boot, and then from the system BIOS to the OS Bootloader using UEFI secure boot.

• Shadow Stack

  Provides hardware-enforced stack protection capabilities address threat vectors such as return oriented programming attacks by keeping a record of the return addresses so a comparison can be made to ensure integrity is not compromised. In addition, AMD Shadow Stack enables Microsoft® hardware enforced stack protection.

For more information, see the AMD Infinity Guard web page:

Configuration requirements

The following table lists the components that are supported based on the ambient temperature.

Acoustic modes

The SE455 V3 supports different acoustic modes, which optimize the operation of system fans to lower the overall noise level of the server. This is achieved by closely monitoring components to ensure they operate within the cooling available.

You can specify which acoustic mode you want enabled in the factory by specifying one of the feature codes listed in the following table in the DCSC configurator. By selecting the mode, the configurator will limit the configuration options to ensure the noise requirements are met. You can also specify or change the acoustic mode in UEFI. During server operation, power capping may be enabled, if needed, to ensure that noise limits are met.

The acoustic modes are designed to run with an ambient temperature of no more than 35°C. Above 35°C, the acoustic mode will be exited to prevent the system from overheating. Once the ambient temperature returns to below 35°C, the acoustic mode will be re-enabled automatically.

The following table lists the components that are recommended in the acoustic modes.

* If a component is listed as “not recommended” then that means that the component usually generates too much heat for the fans to run at a low enough speed to keep the noise of the system low. If the component is installed and is only lightly loaded, it may still be possible to run the server in the Acoustic Mode
