Lenovo ThinkSystem SR630 V3Specifications, configurations & comparisons

The ThinkSystem SR630 V3 fits a pair of Intel Xeon Scalable processors — 4th or 5th Gen — and 32 DDR5 DIMM slots into a single rack unit. Lenovo names databases, virtualisation, cloud and HPC among its target workloads, and room for three single-wide GPUs adds a route to compact inference. This page maps every documented limit — drive layouts, riser and fan rules, liquid cooling and one-socket builds — before you configure one.

01 — Overview

The SR630 V3 at a glance

Our read of Lenovo’s documentation: where the SR630 V3 is strong, and the limits worth knowing before you spec one.

Strengths

  • Two sockets, 32 DDR5 slots and an 8 TB memory ceiling in 1U — the same ceiling Lenovo gives the 2U SR650 V3.
  • A choice of 84 processors from 8 to 64 cores, including 16 single-socket parts for one-processor servers that will never need a second CPU.
  • All twelve 2.5-inch bays (ten front, two rear) or all sixteen E1.S bays can hold NVMe drives on direct onboard links, with no retimer card.
  • The front-I/O chassis places two PCIe 4.0 slots plus the OCP 3.0 adapter on the front panel, beside four 2.5-inch bays.
  • Two liquid-cooling routes for the hottest chips: a closed-loop Neptune Liquid to Air module, or an open-loop Neptune direct-water module plumbed to the rack.

Watch-outs

  • Any processor above 300 W needs one of the Neptune modules or a front cut back to a single 4-bay backplane, and the closed-loop module holds inlet air to 25 °C.
  • Standard (21K RPM) fans are permitted only in a narrow low-power, low-I/O build, so GPU, NVMe-dense, rear-drive and single-CPU servers all run the faster 28K RPM Performance fans.
  • Only three rear slots, and slot 3 hangs off CPU 2 — a one-processor server keeps slots 1 and 2 and half the DIMM slots.
  • With GPUs fitted, processors above 220 W restrict the front to four 2.5-inch SAS/SATA bays, and the L4 is sold only on Lenovo’s “for AI” base models.
  • Lenovo marks the 4 × 3.5-inch AnyBay backplane (B8N1) withdrawn, so the 3.5-inch front is SAS/SATA only; NVMe then has to come from the rear bays.

  • The single-socket SKUs are 3408U, 3508U, 5411N, 5412U, 5423N, 5433N, 5512U, 6403N, 6414U, 6423N, 6433N, 6443N, 8461V, 8558U, 8571N and 8581V. They have no UPI links, so a server built around one stays a one-processor machine.
  • Above 300 W TDP, the chassis needs the Neptune Liquid to Air module, the Neptune Processor DWC Module, or a front populated with only one 4-bay backplane (BCGB or BPC9).
  • Lenovo’s ambient table holds air-cooled servers to 35 °C with 165–205 W processors and to 30 °C with 205–350 W parts; some 300–350 W and large-DIMM combinations fall to 25 °C.
  • The heatsink — standard, or the Performance type with two satellite heatsinks — is picked automatically by Lenovo’s configurator from the processor and the rest of the build.
  • Intel AMX is built into all Silver, Gold and Platinum models; the QuickAssist, DLB, DSA and IAA engine counts vary from SKU to SKU.
03 — Memory

32 DIMM slots, 16 per processor

Sixteen DIMM sockets sit beside each processor — eight channels, two sockets per channel — giving 32 with both CPUs fitted. Lenovo allows one, two, four, six, eight, twelve or sixteen modules per processor. Eight per CPU keeps a single DIMM in every channel and the highest data rate; sixteen doubles capacity at a lower speed.

  • * For 5th Gen processors with two modules in a channel, Lenovo’s DDR5 rules quote 4400 MT/s for RDIMMs and 3DS RDIMMs and 4800 MT/s for Performance+ RDIMMs only, whereas the SR630 V3 specification table simply states 4800 MT/s at 2 DPC.
  • Selectable DIMMs follow the processor generation: 5600 MHz modules with 5th Gen, 4800 MHz with 4th Gen. One module, 4X77A93887 (128 GB, 2Rx4), crosses both generations, and four 5th Gen parts — Bronze 3508U, Silver 4509Y, Silver 4510, Silver 4510T — can also use the 4800 MHz range.
  • 96 GB modules have their own quantity rules: 1, 6, 8, 12 or 16 per processor with 5th Gen, and only 8 or 16 with 4th Gen.
  • Lenovo’s thermal note for the 128 GB 3DS RDIMM (feature BY8F) calls for the Performance fans and rules out rear 2.5-inch drives and GPUs.
  • Mixing 9x4, 10x4 and 3DS modules, x4 with x8 organisations, or 16, 24 and 32 Gb DRAM is not allowed; 9x4 modules also lose memory mirroring and ADDDC.

20 backplane options, up to 16 bays

The 1U front takes one of three drive families: up to ten 2.5-inch bays, four 3.5-inch bays or sixteen E1.S EDSFF bays. A rear module adds either two 2.5-inch hot-swap bays or two 7mm boot drives. The bay map shows four complete 2.5-inch layouts from Lenovo’s configuration tables; the E1.S and 3.5-inch fronts are covered in the notes.

The 1U chassis has room for three single-width GPU cards, each rated at no more than 75 W. Lenovo’s GPU table currently lists one card, the NVIDIA L4 24 GB, for slots 1, 2, 3 and 5. It is a Controlled GPU, so it is built only on the “for AI” base CTO models; all GPUs in a server must match, and passively cooled cards need the Performance fans. Up to 3 × single-wide GPUs, up to 75 W each (NVIDIA L4 listed).

9 power supplies, 750–1,800 W

The server runs on a matched pair of hot-swap supplies. AC choices are 750, 1100 and 1800 W, each in a Titanium or a Platinum version, and telco sites can use an 1100 W −48 V DC unit instead. In Lenovo’s power table only the two smaller Platinum units carry a 110 V AC tick; the other AC supplies need 200–240 V.

  • Every AC supply uses a C14 inlet, so standard C13 rack cables apply; the −48 V unit has a Weidmuller TOP 4GS/3 7.6 terminal.
  • Measured from the rack-flange mounting surface, depth to the PSU handles is 754 mm with supplies up to 1100 W and 782 mm with the 1800 W units.
  • Cooling is up to eight 40 mm dual-rotor hot-swap fans — six with one processor, eight with two — with N+1 rotor redundancy, plus a fan inside each supply.
  • Standard (21K RPM) fans need two processors under 165 W, no GPUs, no 100 Gb-plus adapters or Broadcom 57454 4-port 10GBASE-T OCP card, no rear drives and no EDSFF or 8/10-bay NVMe or AnyBay front; everything else, and every one-processor build, uses the Performance (28K RPM) fans.
  • Chinese installations can also feed the supplies from a 240 V DC source.

Four builds that suit the SR630 V3

Four builds that suit a 1U two-socket server, every part chosen from the options our configurator permits for the SR630 V3. Open any of them to change it; Lenovo’s fan, riser and ambient-temperature rules for the finished mix are checked before we quote.

Virtualisation

Ten-drive NVMe cluster node

Two 32-core 5th Gen processors, 1 TB at one DIMM per channel and ten NVMe drives on direct onboard links make a dense host for vSAN-style local storage. The 6538Y+ memory bus tops out at 5200 MT/s, so the 5600 MHz DIMMs run at that rate.

  • 2 × Xeon Gold 6538Y+ — 32 cores @ 2.2 GHz, 225 W each
  • 16 × 64 GB TruDDR5 — 1 TB, one DIMM per channel
  • 10 × 3.84 TB NVMe U.3 on the ten-bay NVMe backplane
  • 2 × 480 GB M.2 boot drives in RAID 1
  • NVIDIA ConnectX-6 Lx 2 × 25GbE OCP 3.0
  • 2 × 1100 W Titanium
  • VMware ESXi 8.0

A ten-bay NVMe front requires the Performance fans, and air-cooled servers with processors above 205 W are limited to 30 °C inlet air.

Branch & edge

One-socket branch server

A single 28-core Gold 5512U — a one-socket part with no UPI links — with eight DIMMs, four 12 TB 3.5-inch drives behind a flash-backed RAID controller and 10GBASE-T networking, for a branch file and VM host in 1U.

  • 1 × Xeon Gold 5512U — 28 cores @ 2.1 GHz, 185 W
  • 8 × 32 GB TruDDR5 — 256 GB, at 4800 MT/s on this processor
  • 4 × 12 TB 3.5-inch SATA HDD — 48 TB raw
  • RAID 940-8i with 4 GB flash cache
  • 2 × 480 GB M.2 boot
  • Broadcom 57416 2 × 10GBASE-T OCP 3.0
  • 2 × 750 W Titanium
  • Windows Server 2025

With one processor only slots 1 and 2 and 16 DIMM slots are usable, and Performance fans are mandatory. A U-suffix processor cannot be joined by a second CPU later.

Databases

Licence-lean SQL Server host

Two 8-core Gold 5515+ processors keep the core count — and core-based licensing — small while running at 3.2 GHz base. The RAID 940-16i sits in the internal cabled (CFF) bay, so it takes no PCIe slot and leaves the rear free for networking.

  • 2 × Xeon Gold 5515+ — 8 cores @ 3.2 GHz, 165 W each
  • 16 × 64 GB TruDDR5 — 1 TB, at 4800 MT/s on this processor
  • 8 × 3.84 TB SAS SSD on the eight-bay SAS/SATA backplane
  • RAID 940-16i 8 GB flash, internal (CFF) form factor
  • 2 × 480 GB M.2 boot
  • Broadcom 57414 2 × 25GbE OCP 3.0
  • 2 × 1100 W Titanium
  • Windows Server 2025

Lenovo offers the internal CFF adapter bay only with 2.5-inch front drives.

AI inference

Three-GPU inference in 1U

Three NVIDIA L4 cards — the most the chassis takes — with two 28-core Gold 5520+ processors kept below the 220 W point at which Lenovo restricts GPU servers to a four-bay SAS/SATA front, so NVMe bays stay available.

  • 2 × Xeon Gold 5520+ — 28 cores @ 2.2 GHz, 205 W each
  • 3 × NVIDIA L4 24 GB, single-wide, passively cooled
  • 16 × 64 GB TruDDR5 — 1 TB
  • 4 × 7.68 TB NVMe U.3 on the ten-bay NVMe backplane
  • Intel E810-DA2 2 × 25GbE OCP 3.0
  • 2 × 1800 W Titanium
  • Ubuntu Server 24.04 LTS

The L4 is a Controlled GPU, built only on Lenovo’s “for AI” base models. The third card needs slot 3 and therefore CPU 2; passive GPUs require the Performance fans, and an L4 at the rear limits inlet air to 30 °C.

12 — FAQ

SR630 V3 questions, answered from the documentation

What is the maximum memory of the Lenovo ThinkSystem SR630 V3?

Lenovo quotes 8 TB for a two-processor server, with each of the 32 slots holding a 256 GB 3DS RDIMM. Because Lenovo pairs that module with 5th Gen parts only, a server on 4th Gen processors is limited to 32 × 128 GB, which is 4 TB. A one-processor SR630 V3 has 16 slots, and Lenovo’s one-processor section gives 2 TB for it.

Which processors does the SR630 V3 support?

Eighty-four Intel Xeon Scalable SKUs are listed — 52 4th Gen and 32 5th Gen. The smallest have 8 cores, and the Platinum 8592+, 8592V and 8593Q reach 64; ratings run up to 385 W. Sixteen SKUs, every U-suffix part among them, work only as the single processor in a one-socket server.

How many drives fit in the SR630 V3?

Up to twelve 2.5-inch drives (ten front, two rear), sixteen E1.S EDSFF drives, or four 3.5-inch drives at the front. Boot uses either an internal M.2 pair or two 7mm drives in the rear, never both. All twelve 2.5-inch bays, or all sixteen E1.S bays, can be NVMe on direct onboard connections.

Does the SR630 V3 support GPUs?

Yes — three single-width cards at most, each no more than 75 W. The card Lenovo lists is the NVIDIA L4 24 GB; as a Controlled GPU (one the US Government restricts in some markets), it ships only in servers ordered on a “for AI” base CTO model. GPU servers need the Performance fans, and with processors above 220 W their front is limited to four 2.5-inch SAS/SATA bays.

How many PCIe slots does the SR630 V3 have?

Up to five: three x16 slots at the rear, where slot 3 needs the second processor, and two PCIe 4.0 slots at the front in the four-bay front-I/O layout. There is also one OCP 3.0 slot, at the rear (PCIe 5.0) or the front (PCIe 4.0) but not both.

What power supplies does the SR630 V3 use?

A pair of matching hot-swap supplies — AC units of 750, 1100 or 1800 W (Titanium or Platinum), or a DC unit of 1100 W for −48 V feeds. For 115 V mains, pick the 750 W or 1100 W Platinum; every AC supply has a C14 inlet.

How big and heavy is the SR630 V3?

It is a 1U server 440 mm wide (482 mm across the rack flanges), 43 mm high and 773 mm deep. From the rack-flange mounting surface to the power-supply handles it measures 754 mm with supplies up to 1100 W and 782 mm with 1800 W units. Maximum weight is 20.8 kg.

How does the SR630 V3 differ from the SR650 V3?

They share the 4th and 5th Gen Xeon families, 32 DIMM slots and the 8 TB ceiling. The 2U SR650 V3 has room for 40 × 2.5-inch or 20 × 3.5-inch drives and up to eight single-width (or three double-wide) GPUs; the 1U SR630 V3 stops at twelve 2.5-inch, sixteen E1.S or four 3.5-inch bays and three single-wide GPUs.

What changed in the SR630 V4?

The SR630 V4 moves to Intel Xeon 6 — up to 86 P-cores or 144 E-cores — with DDR5 up to 6400 MHz and MRDIMM and CXL memory on P-core models. It swaps E1.S for 16 × E3.S 1T or 8 × E3.S 2T bays, adds a second rear OCP slot and XClarity Controller 3, and drops 3.5-inch bays and onboard SATA.

Is the Lenovo ThinkSystem SR630 V3 end of life?

No end-of-life or end-of-service date appears in Lenovo’s SR630 V3 product guide, which still carries the model with current processor and option tables. Cover after the base warranty depends on the service contract, and our end-of-life checker shows dates once Lenovo publishes them.
