ThinkEdge SE455 V3

The Lenovo ThinkEdge SE455 V3 is a single-socket server, with a 2U height and short depth case that can be mounted in a 2-post or 4-post rack. This rugged edge server can handle continuous operating temperatures from 5°C and 55°C as well as tolerance to locations with high-dust and vibration.

The ThinkEdge SE455 V3 is based on the new AMD EPYC 8004 Series "Siena" 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 SE455 V3 one of the most powerful, yet quiet servers on the market, allowing it to be deployed next to end users without disturbing the workplace.

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"
• Up to 64 cores
• Core speeds of up to 2.65 GHz
• TDP ratings of up to 225W
• Support for up to 6 TruDDR5 memory DIMMs and up to 576 GB of memory using 96 GB DIMMs
• DIMMs operate at up to 4800 MHz for a fast memory subsystem
• Supports up to 6x single-width GPUs or 2x double-wide GPUs, for substantial processing power in an edge system.
• Supports up to 6x AMD Alveo V70 Datacenter Accelerator adapters, tuned for video analytics and natural language processing workloads
• Support for up to 8x 2.5-inch drive bays, 4x hot-swap drives at the front of the server, and 4x non-hot swap drives internal to the server. Optional RAID with the addition of a RAID adapter installed in a slot.
• Supports M.2 drives for convenient operating system boot functions. Available M.2 adapters support either one M.2 drive or two M.2 drives. M.2 with RAID is available now using a PCIe RAID adapter; support for an M.2 adapter with integrated RAID is planned for 1Q/2024.
• Supports 8x NVMe drives without oversubscription of PCIe lanes (1:1 connectivity). The use of NVMe drives maximizes drive I/O performance, in terms of throughput and latency.
• Supports up to 6x full-height PCIe slots, all front accessible, plus an additional OCP adapter slot
• The server has a dedicated industry-standard OCP 3.0 small form factor (SFF) slot supporting a variety of Ethernet network adapters. Simple-swap mechanism with thumbscrews and pull-tab enables tool-less installation and removal of the adapter. Supports shared BMC network sideband connectivity to enable out-of-band systems management.
• The server offers PCI Express 5.0 (PCIe Gen 5) I/O expansion capabilities that doubles the theoretical maximum bandwidth of PCIe 4.0 (32GT/s in each direction for PCIe 5.0, compared to 16 GT/s with PCIe 4.0). A PCIe 5.0 x16 slot provides 128 GB/s bandwidth, enough to support a 400GbE network connection
