Lenovo 7DCEA01UNA Thinksystem ST250 V3 95W 16G

Lenovo 7DCEA01UNA ThinkSystem ST250 V3 Tower Server

The Lenovo ThinkSystem ST250 V3, model 7DCEA01UNA, is a single-socket tower server built around the Intel Xeon E-2488 processor — a workstation-class chip that brings 8 cores, 3.2 GHz base, and 5.6 GHz boost to compact on-premises deployments. This configuration ships with 16 GB of DDR5-4800 ECC RAM and four DIMM slots that scale to 128 GB, making it a practical fit for edge recording workloads, branch-office infrastructure, and mid-scale physical security backends where rack space is limited or a data closet is the target environment.

Key Features

• Intel Xeon E-2488 Processor (3.2 / 5.6 GHz, 8 Cores, 24 MB Cache): The E-2488 is Intel's highest-tier Xeon E entry — 8 performance cores with a 5.6 GHz max boost handle compute-intensive tasks like simultaneous video decode, AI-assisted analytics offload, and multi-stream recording without the overhead of a dual-socket platform. The 24 MB L3 cache matters for NVR-style workloads that repeatedly access the same frame buffers.
• DDR5-4800 ECC Memory (16 GB installed, expandable to 128 GB): DDR5 at 4800 MHz delivers roughly 50% more peak bandwidth than DDR4-3200, which translates directly to sustained multi-channel video throughput. ECC (Error-Correcting Code) catches single-bit memory errors silently — critical for 24/7 recording servers where a memory fault that crashes a workstation would mean dropped footage. The four DIMM slots and 128 GB ceiling give you room to grow as camera counts increase or if you add analytics workloads later.
• RAID 0 / 1 / 5 / 10 / 50 Support with Compatible 5350-8i Controller: RAID 5 and RAID 10 are the two configurations most integrators reach for on NVR servers — RAID 5 for storage efficiency, RAID 10 for write performance on dense streams. Having RAID 50 available means you can configure dual-parity stripe sets for larger drive bays without sacrificing too much usable capacity. The supported controller is the Lenovo RAID 5350-8i; confirm that controller is present or ordered separately before deployment.
• Tower Form Factor (12 × 30 × 26 in, 50 lb): At 50 lb and roughly 2.5 cubic feet, this unit fits under a desk, in a small IT closet, or on a low shelf without rack infrastructure. For retrofits in buildings where a rack cabinet is not installed, the tower form factor eliminates the need for a rack enclosure purchase entirely — a real cost and time difference in small-site security upgrades.
• 128 GB Maximum Memory Headroom: If this server is being deployed as an on-premise VMS host, 128 GB of addressable RAM means you can run a hypervisor (Hyper-V, VMware ESXi) alongside the VMS without memory pressure — dedicating, for example, 64 GB to the recording engine and reserving the rest for access control, analytics, or operational systems sharing the same hardware footprint.
• ECC Memory for 24/7 Reliability: Unlike consumer or workstation DIMMs, ECC corrects in-flight bit errors caused by cosmic radiation and electrical noise — a failure mode that matters more on always-on servers than on machines that restart daily. For security integrators guaranteeing uptime SLAs on surveillance infrastructure, ECC is a baseline requirement, not an optional upgrade.

Integration and Compatibility

The 7DCEA01UNA pairs with major VMS platforms that publish Windows Server or Linux system requirements — including Milestone XProtect, Genetec Security Center, Axis Camera Station, and Hanwha WaveNet — provided the target platform's hardware requirements are validated against the Xeon E-2488 and the installed RAID controller configuration. Lenovo publishes an online compatibility matrix for ThinkSystem platforms; verify storage controller, drive, and OS combinations there before committing to a configuration. The RAID 5350-8i controller supports both HDD and SSD drive types, giving you flexibility between high-capacity spinning media for long-retention recording and SSD for OS and database volumes.

This server is manufactured in Mexico (Country of Origin: MX) and carries UNSPSC code 43211502, classifying it as a rack-mount or tower server for procurement and cataloging purposes. For enterprise procurement teams using commodity codes for purchase-order classification, this code aligns with standard server procurement categories.

Frequently Asked Questions

Q: What processor does the Lenovo 7DCEA01UNA include?

A: The 7DCEA01UNA ships with the Intel Xeon E-2488 — an 8-core processor with a 3.2 GHz base clock and 5.6 GHz max boost, 24 MB L3 cache. It is a single-socket configuration.

Q: How much RAM comes installed, and what is the maximum?

A: This configuration ships with 16 GB of DDR5-4800 ECC RAM in a single DIMM. The server has four DIMM slots and supports up to 128 GB total, giving you substantial headroom to add memory as workloads grow.

Q: Does this server support RAID, and which levels?

A: Yes. The ThinkSystem ST250 V3 supports RAID levels 0, 1, 5, 10, and 50 with the compatible Lenovo RAID 5350-8i controller. Confirm whether that controller is included in your specific order or needs to be added separately.

Q: Is this a rack-mount or tower server?

A: Tower. The unit measures 12 × 30 × 26 inches and weighs 50 lb — it does not require a rack enclosure and is suited to closet, desktop, or under-desk deployments where rack infrastructure is unavailable.

Q: Is the memory ECC-capable?

A: Yes. All installed and expandable memory runs ECC (Error-Correcting Code), which silently corrects single-bit errors during operation. This is the correct choice for any 24/7 recording or always-on infrastructure role.

Q: Where is the Lenovo 7DCEA01UNA manufactured?

A: Country of Origin is Mexico (MX), per the product's structured distribution data.

The 7DCEA01UNA is the configuration I'd point an integrator toward when the job calls for a compact on-premises VMS host with real compute muscle — not an entry-level box with a desktop chip bolted in. The Xeon E-2488 at 5.6 GHz boost with 24 MB of L3 cache handles simultaneous multi-stream decode without falling behind on dense camera counts, and the DDR5-4800 ECC memory gives you the bandwidth and reliability baseline that 24/7 recording actually demands.

Technical Highlights:

• Xeon E-2488 at 5.6 GHz Max Boost: For VMS platforms running software decode on 30+ camera streams, that boost ceiling matters — the CPU can hit peak frequency on the decode threads without starving OS or analytics processes running concurrently.
• 128 GB DDR5 ECC Ceiling: Four DIMM slots means you can start at 16 GB and double-stack to 128 GB as camera counts grow. DDR5-4800 also gives you enough memory bandwidth headroom to run a hypervisor and still allocate 64+ GB to the recording engine alone.
• RAID 5 / 10 / 50 Flexibility: RAID 50 support is the differentiator here — for larger drive arrays, you can build dual-parity stripe sets that protect against multi-drive failure without the massive capacity penalty of RAID 6 on smaller arrays.

Deployment Considerations:

• Verify whether the Lenovo RAID 5350-8i controller is included in your specific order. The ThinkSystem ST250 V3 platform supports it, but it may be a separate line item depending on the SKU variant you're ordering — check the bill of materials before submitting your PO.
• At 50 lb and 26 inches deep, plan your closet or cabinet space accordingly — this is not a lightweight unit, and the depth can be a problem in shallow wall-mount enclosures.

This server is the right fit for a multi-building physical security deployment where the customer needs a tower-form VMS host at each site — enough headroom to run Milestone or Genetec with a local analytics workload, without the cost or complexity of a rack build-out at every location.
