01 — Overview

The SE100 at a glance

Our read of Lenovo’s documentation: where the SE100 is strong, and the limits worth knowing before you spec one.

Strengths

  • One node, many installations: on a desk, on a wall or ceiling through the VESA sleeve, on a DIN rail, or two or three to a 1U rack enclosure.
  • The base node meets ASHRAE A4 (5–45 °C) and IP50 dust protection, and its desk, wall, ceiling and DIN mounts are specified for 15 G operating shock and 0.15 Grms operating vibration.
  • System Lockdown Mode, managed from the ThinkShield Key Vault Portal, can ship the node locked and lock it again after tampering until an administrator re-authenticates it.
  • A single expansion kit adds either an NVIDIA RTX A1000 or RTX 2000E Ada for local inference, or a quad-1GbE or dual-10GBASE-T network card.
  • XClarity Controller 2 has its own rear RJ45 port, so a site without IT staff can still be managed remotely; the XCC2 Platinum upgrade adds remote console and virtual media.

Watch-outs

  • The processor is soldered and cannot be upgraded; the only choices are the 14-core Core Ultra 5 225H and 16-core Core Ultra 7 255H, neither with Hyper-Threading.
  • There are no ECC DIMMs. Memory is non-ECC SODIMM or CSODIMM, and Intel’s in-band ECC works only with one module or a pair of equal capacity.
  • Storage is M.2 only — no 2.5-inch drives, no hardware RAID and currently no Intel VROC — and data capacity stops at 2 × 3.84 TB.
  • The one expansion slot takes a GPU or a network card, not both. A GPU limits the node to 35 °C, the expansion kit is not IP50-rated, and the listed GPUs are unsupported under Windows 11 IoT Enterprise.
  • Power is external only, from 140 W or 300 W USB-C PD adapters, and the only supported hypervisor is KVM on Ubuntu 24.04 — no ESXi, Hyper-V or Xen.

  • Lenovo marks turbo as supported but prints no turbo frequency; the 28 W figure is the processor base power.
  • Shared features include AVX2 and OpenVINO for AI, VT-x and VT-d, AES-NI, Trusted Execution Technology, Boot Guard and MBEC; Intel OS Guard is listed as planned.
  • Integrated Intel graphics (Xe2 architecture) drive two front HDMI 2.0 outputs and a USB-C DisplayPort at up to 3840 × 2160 at 60 Hz, separately from the XCC2 display.
  • Processors come only in factory builds or preconfigured models; there are no option part numbers for field upgrades.
03 — Memory

2 DDR5 DIMM slots

Two DDR5 slots, one per memory channel, take 16 or 32 GB modules: SODIMMs at 5600 MHz or CSODIMMs at 6400 MHz. A pair of 32 GB modules reaches the 64 GB maximum. Speeds and capacities cannot be mixed across the two channels, and none of the modules is ECC.

  • In-band ECC, Intel’s software alternative to ECC DIMMs, works with a single module or two of the same capacity; a 16 GB plus 32 GB pair loses it.
  • Memory mirroring, rank sparing and SDDC (Chipkill) are not supported; the memory runs in independent mode.
  • Modules from different vendors may be mixed.
  • Lenovo’s temperature table supports every listed module across the full 5–45 °C range.
04 — Storage

Storage and boot

There are no drive bays. The system board has three M.2 sockets: one 2280 boot socket, a PCIe 4.0 x4 slot that also accepts SATA drives, and two NVMe data sockets that take 2280 or 22110 drives. Data drives of 2280 length need a holder, the two lengths cannot be mixed, and every listed SSD is non-hot-swap.

Controllers & boot

  • Onboard NVMe (M.2 slots attached directly to the processor) — Onboard NVMe (no hardware RAID), N/A cache. lp1995 L463 "No Hardware RAID support and currently no Intel VROC RAID support"; the storage is the M.2 slots only - one 2280 SATA/NVMe boot slot on PCIe 4.0 x4 (L474) and two NVMe data slots (L476). No storage-controller table in the guide.
  • 1 x M.2 2280 SATA/NVMe boot slot (PCIe 4.0 x4); no RAID — boot
  • Boot drives: 480 GB or 960 GB NVMe (7450 PRO or VA) or 480 GB or 960 GB SATA (ER3).
  • Data drives: 480 GB and 960 GB NVMe in 2280 length; 960 GB, 1.92 TB and 3.84 TB NVMe in 22110 length. Two 3.84 TB drives give the 7.68 TB maximum.
  • Temperature: with NVMe M.2 data drives Lenovo asks for ambient below 40 °C and with an NVMe boot drive below 35 °C, or performance may degrade.
  • Self-encrypting M.2 drives can be enabled at the factory (feature BYBS), independently of System Lockdown Mode, although the guide’s summary table lists SED, intrusion detection and UEFI passwords as unsupported.
  • There is no hardware RAID and, currently, no Intel VROC RAID, and Provisioning Manager’s RAID functions are not supported on this server.
05 — Accelerators & I/O

GPUs, PCIe and networking

GPUs need the SE100 Expansion Kit for Active Cooling GPU (C30F), which adds a PCIe 4.0 slot, x16 physical and x8 electrical, for one single-wide low-profile card of up to 75 W. Lenovo lists two cards: the NVIDIA RTX A1000 8GB and the RTX 2000E Ada 16GB. One low-profile GPU up to 75 W · 5–35 °C ambient only · not in the 1U3N enclosure.

06 — Power & cooling

2 power supplies, 140–300 W

The SE100 has no internal power supply. It runs from one or two external AC adapters that deliver 28 V over USB-C Power Delivery, and with two connected it is 1+1 redundant. Which adapter you need depends on how the node is mounted.

AC
  • Desktop, wall, ceiling and DIN installations use the 140 W adapter (28 V, 5.0 A); the 300 W adapter is for the 1U2N and 1U3N rack enclosures only.
  • The 300 W adapter gives each node 140 W when feeding one or two nodes and 100 W each when feeding three (280 W over two ports, 300 W over three).
  • Both adapters accept 100–240 V at 50–60 Hz. The node itself accepts 20–28 V DC from adapters above 100 W that meet USB PD 3.0 or 3.1.
  • Ambient limits follow the adapter: under 45 °C with 140 W adapters, under 35 °C with 300 W adapters, and 5–35 °C whenever the node sits in a rack enclosure.
  • Cooling uses two non-hot-swap 6513 fans in the base node, enclosure fan modules in rack use, and two 5010 blowers with the network kit; fans are redundant but not hot-swap.

08 — Compare

How the SE100 compares with its family

The SE100 sits beside the ThinkEdge SE455 V3, a much larger AMD EPYC edge server that takes up to six GPUs. Where the site has no need for an edge-hardened box, the ST45 V3 and ST50 V3 towers and the SR250 V3 1U rack server are Lenovo’s small conventional servers. The bars compare the limits in each model’s spec file.

09 — Use cases

Four builds that suit the SE100

Four SE100 builds for the retail, manufacturing and branch roles Lenovo aims it at, built from options our configurator permits for the SE100. The configurator models the boot M.2 socket; M.2 data drives and mounting kits are added when we quote.

Edge AI · video analytics

Camera-stream inference box

Lenovo targets the SE100 at video analytics, smart surveillance and edge AI in retail and manufacturing. The 16-core 255H with a 16 GB RTX 2000E Ada handles inference close to the cameras, on Ubuntu 24.04 from Lenovo’s support list.

  • 1 × Core Ultra 7 255H — 16 cores @ 2 GHz, 28 W
  • 2 × 32 GB CSODIMM at 6400 MHz — 64 GB
  • 480 GB M.2 NVMe boot SSD
  • NVIDIA RTX 2000E Ada 16GB in the GPU expansion kit
  • 2 × 140 W external adapters (1+1)
  • Ubuntu 24.04 LTS

GPU nodes are limited to 5–35 °C ambient, the expansion kit is not IP50-rated, and GPU nodes cannot go in the 1U3N enclosure.

Retail · store server

In-store workload consolidation

Workload consolidation is one of Lenovo’s named SE100 targets, and KVM on Ubuntu 24.04 is its supported hypervisor. Two matched 32 GB SODIMMs keep in-band ECC, and a 10GBASE-T card gives the store a faster uplink than the onboard 1GbE ports.

  • 1 × Core Ultra 5 225H — 14 cores @ 1.7 GHz, 28 W
  • 2 × 32 GB SODIMM at 5600 MHz — 64 GB
  • 480 GB M.2 NVMe boot SSD
  • Broadcom 57416 2 × 10GBASE-T in the network expansion kit
  • 2 × 140 W external adapters (1+1)
  • Ubuntu 24.04 LTS (KVM host)

With the network kit fitted the node is no longer IP50-rated, and the slot cannot also take a GPU.

Branch or factory rack

Three gateway nodes in 1U

The 1U3N enclosure puts three SE100 nodes and two shared 300 W adapters into one rack unit, each one a separate SE100 server — a way to run separate gateways or control workloads side by side in a comms cabinet.

  • 1 × Core Ultra 5 225H — 14 cores @ 1.7 GHz, 28 W
  • 2 × 16 GB CSODIMM at 6400 MHz — 32 GB per node
  • 480 GB M.2 NVMe boot SSD
  • 2 × 300 W external adapters, shared by the enclosure’s three nodes
  • Red Hat Enterprise Linux 9

In a rack enclosure the SE100 is rated for 5–35 °C, and with an NVMe boot drive Lenovo advises keeping the room below 30 °C. The 1U3N accepts nodes without expansion kits only.

Open this build in the configurator →
Industrial · DIN rail

Line-side controller at 45 °C

Kept to the base node, the SE100 retains its IP50 rating and the full ASHRAE A4 range up to 45 °C. A SATA boot SSD avoids the lower ambient limits Lenovo sets for NVMe M.2 drives, and the optional DIN Mount Kit (Extreme Shock & Vibe) fixes the node sleeve to a rail.

  • 1 × Core Ultra 5 225H — 14 cores @ 1.7 GHz, 28 W
  • 2 × 16 GB SODIMM at 5600 MHz — 32 GB
  • 2 × 140 W external adapters (1+1)
  • Ubuntu 24.04 LTS

The boot SSD is one of Lenovo’s listed ER3 SATA M.2 drives (480 GB or 960 GB), added on our quote: the 240 GB ER3 in our configurator appears in Lenovo’s temperature tables but not in its drive list. The DIN kit, node sleeve (C31B) and node fan kit are also added on the quote, and the 300 W adapter is not supported on a wall or DIN rail.

When a refurbished server makes more sense

Nothing in our refurbished Dell and HPE ranges matches a 2.1-litre node that can be screwed to a wall or clipped to a DIN rail. Where the site has a rack and a clean, cool room, though, a refurbished 1U server can take the same branch workloads with far more memory and drive bays.

12 — FAQ

SE100 questions, answered from the documentation

How big is the Lenovo ThinkEdge SE100?

The base node is 142.3 mm wide, 53 mm high and 278 mm deep — 2.1 litres — and weighs up to 2.36 kg. The PCIe expansion kit widens it to 214.2 mm and 3 kg, and three bare nodes fit side by side in the 1U3N rack enclosure.

How can the SE100 be mounted?

On a desk on rubber feet, on a wall or ceiling via the VESA node sleeve, on a DIN rail with the DIN Mount Kit, or in a rack using the 1U2N enclosure (two nodes with expansion kits) or 1U3N enclosure (three nodes without). Rack enclosures use the 300 W adapter, which is not supported on a desk, wall or DIN rail.

What conditions can the SE100 operate in?

The base node is rated ASHRAE A4, 5–45 °C, with IP50 dust protection, 8–90% humidity and a 3,050 m altitude limit. GPUs, rack enclosures and 300 W adapters bring the ceiling down to 35 °C, NVMe M.2 data and boot drives call for below 40 °C and 35 °C to avoid performance loss, and the expansion kit is not IP50-rated.

What is the maximum memory of the SE100?

64 GB, from two 32 GB DDR5 modules — CSODIMMs at 6400 MHz or SODIMMs at 5600 MHz — in its two slots. ECC DIMMs are not supported; Intel’s in-band ECC needs a single module or two of the same capacity.

Which processors are available in the SE100?

Two, soldered at the factory: the Intel Core Ultra 5 225H with 14 cores and the Core Ultra 7 255H with 16 cores, both at 28 W base power without Hyper-Threading. The processor cannot be changed later.

How much storage does the SE100 support?

One M.2 2280 boot SSD, SATA or NVMe, and two M.2 NVMe data SSDs of up to 3.84 TB each, for 7.68 TB of data storage. There are no 2.5-inch bays and no RAID of any kind, hardware or VROC.

Can the SE100 take a GPU?

Yes, one, through the Active Cooling GPU expansion kit: an NVIDIA RTX A1000 8GB or RTX 2000E Ada 16GB, up to 75 W. A GPU node is limited to 35 °C ambient, cannot go in the 1U3N enclosure, and these GPUs are not supported under Windows 11 IoT Enterprise.

How is the SE100 powered?

Which operating systems does the SE100 run?

Lenovo lists Windows 11 Enterprise and its IoT edition, RHEL 9.6 through 10.2, and Ubuntu 24.04 and 26.04 LTS. The only supported hypervisor is KVM on Ubuntu 24.04; ESXi, Hyper-V and Xen are not supported.

Is the ThinkEdge SE100 end of life?

Lenovo’s August 2026 product guide gives no end-of-service date and still lists current models and options for the SE100. It carries a three-year CRU and onsite warranty, and Lenovo Services sells extensions. Any lifecycle date Lenovo later sets for the SE100 will be picked up by our end-of-life tool.
