Customers looking for computing solutions at the edge of their networks often have to compromise -- to use either datacenter-class equipment which is too large and power hungry, or PC based equipment which can't run their enterprise level applications. The ThinkSystem SE350 fits the space between those two extremes. Its compact design, low power usage, and high performance are just the right combination for edge locations. The SE350 can be wall mounted, stacked on a shelf or installed in a rack. It is also designed to operate in rugged environments, up to 55°C.

The ThinkSystem SE350 is a purpose-built server that is half the width and significantly shorter than a traditional server, making it ideal for deployment in tight spaces. The 3.38 liter case can be mounted on a wall, stacked on a shelf or mounted in a rack.

The ThinkSystem SE350 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 has wired connections up to 10GbE and optionally supports both Wi-Fi and LTE wireless connectivity.

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.

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

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 rules apply when selecting the memory configuration:

• The server supports RDIMMs and LRDIMMs, however RDIMMs and LRDIMMs cannot be mixed.
• Memory labelled as 2666 MHz and memory labelled as 3200 MHz can coexist in the same server.
• Supported DIMMs are labelled for 2666 MHz or 3200 MHz, however the processors used by the server run at a lower speed (2133 MHz or 2400 MHz). As a result, the memory bus operates at the lower speed set by the processor.
• Memory mirroring and memory rank sparing are not supported.
• Recommended installation sequence: 1, 4, 2, 3

The following memory protection technologies are supported:

• ECC detection/correction
• SDDC (for x4-based memory DIMMs; look for "x4" in the DIMM description)

The SE350 has one PCIe x32 riser slot that accepts a riser that supplies both M.2 data drive adapter and a PCIe slot, depending on the riser selected. The following figure shows the location of the riser cage.

Figure 9. Location of riser cage

The two halves of the riser, referred to as "wings", support an M.2 or PCIe adapter depending on the riser. The left wing is on the left side as viewed from the front of the server. The following table lists the available riser cards. You can also elect to not have a riser card in the server.

The PCIe Riser Cage, when viewed from the underside, is shown in the following figure. The figure shows an M.2 SATA/NVMe adapter installed in the left wing and an NVIDIA T4 GPU installed in the right wing. The left wing supports SATA or NVMe M.2 drives and the right wing offers a PCIe 3.0 x16 Low Profile slot for supported adapters.

Figure 10. ThinkSystem SE350 PCIe Riser Cage (feature B6FD)

The M.2 Riser Cage, when viewed from the underside, is shown in the following figure. The figure shows an M.2 SATA/NVMe adapter installed in both the left wing (top) and right wing (bottom).

Figure 11. ThinkSystem SE350 M.2 Riser Cage (feature B6FE)

The internal storage of the SE350 server is implemented as M.2 drives. The drives are defined as either boot drives or data drives, based on their intended use in the server.

Internal drives are as follows:

• Data drives are installed in a four-port data drive adapter mounted in the riser card that is installed in a riser slot, as described in the I/O expansion section. One or two four-drive adapters are supported in the SE350 for a total of up to eight data drives.
• Boot drives are installed on an M.2 boot adapter, which in turn is installed in a dedicated slot on the system board (see the figure in the I/O expansion section). Either one or two M.2 drives are supported, depending on the boot adapter selected. SATA drives, either SED or non-SED drives are supported.

The SE350 has the following storage controllers:

• ThinkSystem M.2 Enablement Kit, 7Y37A01092, for boot drives
  • SATA drive: SATA controller of the processor (single drive, no RAID)
  • NVMe drives: No support
• ThinkSystem SE350 M.2 Mirroring Enablement Kit, 4M17A60519, for boot drives
  • SATA drives: Marvell 88SE9230 6 Gbps SATA controller on the M.2 adapter (RAID-0, 1; Hardware RAID)
  • NVMe drives: No support

  Note: The M.2 Mirroring Enablement Kit supports UEFI Boot mode only; no Legacy BIOS support

• ThinkSystem SE350 M.2 SATA/NVMe 4-bay Data Drive Enablement Kit, 4M17A37281, for data drives
  • SATA drives: Intel RSTe SATA controller embedded in the processor (RAID-0, 1, 5, 10; Software RAID)
  • NVMe drives: Direct connection to the processor (supports VROC RAID, as described in the Intel VROC onboard SATA and NVMe RAID section)

  Note: Mixing SATA drives and NVMe drives in the same adapter is not supported.

• ThinkSystem SE350 M.2 SATA 4-Bay Data RAID Mirroring Enablement Kit, 4M17A37606, for data drives
  • SATA drives: two independent Marvell 88SE9230 6 Gbps SATA controllers; each controller connects to two M.2 drives (RAID-0, 1; Hardware RAID); Also supports one M.2 drive in a non-RAID (JBOD) configuration
  • NVMe drives: No support

Ordering information for the controllers is listed in the following table.

The data drive adapters support NVMe or SATA drives depending on the capabilities of the adapter plus the capabilities of the riser card slot (the "wing" as explained in the I/O expansion section) that the data adapter is installed in.

Configuration rules:

• Both left and right wings support NVMe drives when using the SATA/NVMe 4-bay Data Drive Adapter.
• Mixing SATA drives and NVMe drives in the same SATA/NVMe 4-bay Data Drive Adapter is not supported
• The SATA HW RAID Adapter does not support NVMe drives.
• The left wing slot of the riser supports connectivity to the onboard SATA controller via a SATA cable (4Z57A37312), however the right wing slot does not support this cable and therefore does not support SATA drives using the SATA/NVMe 4-bay Data Drive adapter.
• Both left and right wings support SATA drives when using the SATA HW RAID Adapter.
• When one wing uses the M.2 SATA RAID Adapter (4M17A37606) and the other wing uses the non-RAID M.2 SATA/NVMe Adapter (4M17A37281), VROC is not supported to provide RAID for the non-RAID adapter. This applies to config 6 and config 8 in the table below.
• For the data drive adapter and the boot drive adapter, the pairs of drives on opposite sides of the adapter must be the same form factor (that is, same length). See the table in the Internal drive options section for the form factor for each supported drive. The pairs of drives must be the same because they share the same mounting clip, as shown in the following figure:
  • Drive positions 1 and 4 must be M.2 drives with identical form factor, as they share the same mounting clip
  • Drive positions 2 and 3 must be M.2 drives with identical form factor, as they share the same mounting clip

  
  Figure 12. Drive positions in the 4-bay Data Drive Kits (drives 1 and 4 must be the same form factor; drives 2 and 3 must be the same form factor)

The following table lists the supported combinations of drive adapters.

The ThinkSystem M.2 Enablement Kit (single M.2 boot adapter) is shown in the following figure.

The ThinkSystem SE350 M.2 Mirroring Enablement Kit (dual M.2 boot adapter) is shown in the following figure, with one 128GB M.2 drive partially inserted. The second M.2 drive is installed on the other side of the adapter.

VROC SATA RAID (RSTe) is available and supported with all SATA drives. It offers a 6 Gb/s connection to each drive and on the SE350 implements RAID levels 0, 1, 5, and 10. RAID 1 is limited to 2 drives per array, and RAID 10 is limited to 4 drives per array. Hot-spare functionality is also supported.

VROC NVMe RAID offers RAID support for any NVMe drives installed in the ThinkSystem SE350 M.2 SATA/NVMe 4-bay Data Drive Enablement Kit. On the SE350, RAID levels implemented are based on the VROC feature selected as indicated in the following table. RAID 1 is limited to 2 drives per array, and RAID 10 is limited to 4 drives per array. Hot-spare functionality is also supported.

The SE350 supports the VROC NVMe RAID offerings listed in the following table. The VROC Intel SSD Only offering only supports RAID on Intel branded NVMe SSDs; non-Intel branded NVMe SSDs cannot be configured in a RAID array.

Configuration notes:

• Intel VROC (VMD NVMe RAID) Intel SSD Only (feature B9X7) is only supported on Intel-branded SSDs; it is not supported with Solidigm or any other brand of SSDs. Consult the specific drive product guides for details.
• If a feature code is ordered in a CTO build, the VROC functionality is enabled in the factory. For field upgrades, order a part number and it will be fulfilled as a Feature on Demand (FoD) license which can then be activated via the XCC management processor user interface.
• Intel VROC NVMe is supported on all Intel Xeon Scalable processors

The following table lists the supported drive options. The table also indicates which drives are supported in a data drive adapter and which drives are supported in a boot drive adapter.

Configuration requirements:

• SED drives are not available in all markets.
• As described in the I/O expansion section, SATA drives are only supported in the left wing of the riser cards. The right wing of the riser only supports NVMe drives, not SATA drives.
• SATA and NVMe drives with SED encryption enabled are only supported in UEFI Boot mode. Legacy BIOS mode is not supported.
• Boot drive adapters: Both drives in a boot drive adapter must be the same form factor (physical length). See the table below for the form factor for each supported drive.
• Data drive adapters: For CTO orders, all 4 drives in a data drive adapter must be the same form factor, See the table below for the form factor for each supported drive. For field upgrades, it is possible to have drives with a different form factor with some configurations. See the Controllers for internal storage section for details.

The use of M.2 drives in high temperature and high shock & vibration conditions is described in the Operating Environment section.

To view the technical specifications of these drives, see the ThinkSystem SSD Portfolio:

  • 2x 1GbE RJ45 (also support 10/100 Mbps)
  • 2x dedicated ports for remote management (can be used as redundant connections or daisy-chain capable)
  • VGA port
  • 2x USB 3.2 G1 ports (5 Gb/s)

The network modules are shown in the following figure (Wireless network module is now withdrawn).

Figure 15. Ports of the available Network Modules

The block diagrams of the Network Modules are shown in the System architecture section.

The specifications of the connections in the two Wired Network Modules are as follows:

• 10 GbE connections:
  • RJ45 ports or SFP+ cages, depending on the Network Module
  • Routed from the networking functions integrated in the Xeon-D processor
  • Based on the Intel X722 controller
  • Supports iWARP
  • Port 1 of the 10GbE ports can be shared with the XCC management processor for Wake-on-LAN and NC-SI support
• 1GbE RJ45 ports
  • Based on Intel I350 controller

  Note: The Intel I350 controller is not supported by Microsoft for use with Azure Stack HCI. Refer to the following document for additional details: Lenovo ThinkAgile MX Certified Configurations for Azure Stack HCI - V1 Servers.

• 1GbE XCC management ports:
  • Direct connections to the XClarity Controller (XCC) management processor
  • Based on Realtek RTL8363SC controller
  • Two ports, either as a redundant pair of ports or can be used as a daisy chain with multiple nearby SE350 servers

Both Wired Network Modules provide the ability to daisy-chain the XCC management connections thereby reducing the number of ports you need in your management switches and reducing the number of switch ports needed for systems management. With this feature you can connect the first SE350 to your management network and the adjacent SE350 connects to the first SE350. The third SE350 can then connect to the second SE350. Up to 7 servers can be connected in a daisy-chain configuration.

The two management ports of the Wired Network Modules can also be used to form a redundant pair. In such a configuration, they share the same IP address; redundancy is at the Layer 2 level.

The SFP+ ports in the Wireless Network Module and the SFP+ Wired Network Module support the transceivers listed in the following table.

Network cables

The SFP+ ports of the Network Modules support the following fiber optic cables and direct-attach copper (DAC) cables.

The RJ45 ports of the Network Modules support the following Category 6 (CAT 6) cables.

When the SE350 is configured with the security bezel, it is recommended you use the CAT6 Ethernet cables listed in the following table. These cables have connectors that are designed to fit with the SE350 security bezel attached and will ensure that the locking bezel functions correctly.

The following table lists additional supported network adapters that can be installed in the PCIe slot when the PCIe Riser (feature B6FD) is selected.

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 additional supported GPUs that can be installed in the PCIe slot when the PCIe Riser (feature B6FD) is selected.

Configuration notes:

• The use of a GPU in high temperature and high shock & vibration conditions is described in the Operating Environment section.

• 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:
https://lenovopress.com/lp0768-thinksystem-thinkagile-gpu-summary

The SE350 server has three 40 mm non-hot-swap fans. All three are standard and support N+1 redundancy.

The SE350 supports two types of power via a Power Distribution Module (PDM):

• 12V PDM connected to one or two plug-in external AC adapters
• -48V DC wired input for Telco customers

For the 12V PDM, one or two AC adapters are used to provide power. Ordering information is listed in the following table.

Details regarding the use of AC adapters:

• One or two AC adapters are supported.
• When two AC adapters are connected, the second AC adapter is redundant.
• Most configurations have a power budget of less than one AC adapter, however any of the following configurations are likely to exceed the power budget of a single AC adapter and will require the second AC adapter be connected:
  • GPU is installed
  • Any quantity of LRDIMMs are installed
  • Processor with 16 cores is selected
  • Four or more NVMe drives are installed
• In case of failure of a single AC adapter, system will throttle if power budget is above a single adapter capacity
• AC Adapters do not include a line cord. See the next section for available power cords.

Details regarding the use of the -48V DC PDM:

• Input range is -40.8 to -72 VDC, 8.4A
• Hardwired (non-plugged) connection
• Supported 2 meter power cable is listed in the table below (feature B7FE)
• Single power input; no redundancy
• Suitable for Telco and Utilities customers

The SE350 contains an integrated service processor, XClarity Controller (XCC), which provides advanced control, monitoring, and alerting functions. The XCC is based on the Pilot4 XE401 baseboard management controller (BMC) using a dual-core ARM Cortex A9 service processor.

Topics in this section:

• Activation
• Local management
• Lenovo XClarity Mobile
• Remote management
• Lenovo XClarity Provisioning Manager
• Lenovo XClarity Administrator
• Lenovo XClarity Essentials
• Lenovo XClarity Energy Manager

• Wireless reset pinhole (Wireless network module only) - reboots the integrated switch function in the Wireless network module which restarts all wireless functions and all wired ports except the 10GbE connections
• NMI reset pinhole - sends a NMI signal to the processor thereby causing a blue-screen trap of the operating system

The LEDs on the front of the server are as follows:

• Power LED (green) - indicated activation and power status, as follows:
  • Off - Server does not have power applied
  • Fast flash (4 times per second) - Either server has just had power applied and is not ready to be powered on yet, or the server has not been activated yet
  • Slow flash (once per second) - Server is ready to be powered on
  • On solid - Server is powered on
• Identification LED (blue) - lights when the button is pressed or when the function is activated remotely in XClarity Controller.
• System error LED (yellow)

The front of the server also houses an information pull-out tab (also known as the network access tag). See Figure 2 for the location. A label on the tab shows the network information (MAC address and other data) to remotely access the XCC service processor.

The steps to connect the mobile device are as follows:

1. Connect the mobile device via your USB cable and the supplied USB-to-mini-USB cable to the SE350's mini-USB port with the management symbol

• Motion detection

  The server has an onboard G-sensor accelerometer (disabled by default) that will generate an event if the server is moved. As part of the setup process in XCC, you specify the orientation of the server - desktop, ceiling, wall mount, angled in the bookshelf mount. You can also specify the sensitivity of the motion detection. The motion detection feature is standard.

• Support for a Kensington lock and cable

  The server has a slot on the side of the server which a customer-supplied Kensington lock and cable can be attached to, to help prevent theft of the server.

• Intrusion arm/disarm feature

  The Kensington cable slot can also double as an electronic switch to disarm the intrusion switch detection, so that authorized servicing of the hardware can be performed without triggering the security actions. Available as the ThinkSystem SE350 Anti-Tampering Keylock Kit (CTO only). The kit includes a Kensington lock (without cable) that is attached to the outside of the server.

  Note: This intrusion arm/disarm feature is not supported with the 1U or 2U rack enclosure mounting options, due to physical restrictions with the Kensington lock.

• Front bezel with key lock

  Optional component that mounts on the front of the server that restricts access to networking connectors on the front of the server. See Mounting components 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) M.2 drives that ensure data is secured when the drives are powered off
• Administrator password and a power-on password in UEFI
• Onboard Trusted Platform Module (TPM) supporting TPM 2.0 enables advanced cryptographic functionality in the operating system and applications.
• For China users, the server has an internal TCM port that supports a Nationz TPM 2.0 module. Available CTO only.

The server is NIST SP 800-147B compliant.

Ordering information for the security components is listed in the following table.

Security Pack

The Security Pack is the collection of security and activation features of the SE350:

• Unique tamper detection (such as G-sensor) and Automatic actions on tamper detection
• Enablement of local Self-encrypting (SED) authentication key (AK) management
• Mandatory claiming and activation process to identify the owner of SE350 when the server is first delivered/powered on

For new configurations created in DCSC, these features will be enabled by default. To disable them, you will need to select the feature code in the Security tab in DCSC as listed in the following table. All SE350 preconfigured models, as listed in the Models section, have the SE350 Security Pack enabled.

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 in the factory with Security Pack disabled, you cannot enable it at a later time.
• 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 SE350 is designed to be used in a variety of locations -- wall, ceiling, bookshelf, table top -- as well as in a rack.
