Lenovo ThinkSystem ST50 V3Specifications, configurations & comparisons

128 GB, using four 32 GB ECC UDIMMs across the processor’s two channels. One, two or four identical modules are supported; memory runs at 4400 MHz with one or two DIMMs and at 3600 MHz with four dual-rank DIMMs, whatever their rated speed.

Lenovo’s features table lists 18 single-socket parts: eight Xeon 6300, eight Xeon E-2400 and the Pentium G7400 and G7400T, from 2 to 8 cores and 35 W to 95 W. Its CTO ordering table currently names ten of them — the G7400, the E-2436 and the eight Xeon 6300 models.

Four at most: three 3.5-inch SATA drives and one 2.5-inch SATA SSD, all non-hot-swap and mounted inside the case. Adding the M.2 boot adapter costs the third 3.5-inch bay, because both use slot 3. Three 8 TB HDDs give Lenovo’s stated maximum of 24 TB.

Yes. Its XClarity Controller 2 has a dedicated rear 1GbE port and supports Redfish, IPMI 2.0 and SNMPv3, and one onboard port can also carry management traffic. The optional XCC2 Platinum licence adds remote console, virtual media, power capping and System Guard.

Three full-height, half-length slots: slot 2 is PCIe 5.0 x16 at 75 W, and slots 1 and 3 are open-ended PCIe 4.0 x4 at 25 W. Lenovo supports no GPU in this server, and slot 3 is also where the M.2 adapter or the third drive-bay kit goes.

A single fixed supply, 300 W Gold or 500 W Platinum, on 110 V or 220 V AC. There is no redundant option; the 500 W unit is the ErP Lot 9-compliant choice.

It is 170 mm wide, 376 mm tall on its stand and 315 mm deep, and weighs 11.96 kg fully configured. Its declared sound pressure is 20.3 dBA at idle and 35.1 dBA with the processor fully loaded, measured on a light typical build with one DIMM and one HDD.

The two share a 17-litre case, four drive positions at most and the choice of a fixed 300 W or 500 W supply. The ST50 V3 runs Intel processors of up to 8 cores, takes 128 GB in four slots, adds a PCIe 5.0 x16 slot, two 1GbE ports and an XClarity Controller, and boots from M.2 SATA drives on a slot-3 adapter. The AMD-based ST45 V3 offers up to 16 cores but 64 GB, USB-key management only and two M.2 NVMe sockets on its system board.

Lenovo’s comparison shows DDR5 in place of DDR4 at the same 128 GB, Xeon 6300 or E-2400 instead of E-2300, a fourth drive position, two M.2 SATA boot drives instead of one M.2 NVMe, a PCIe 5.0 x16 slot, a second onboard 1GbE port and an XClarity Controller where the V2 had Intel AMT. The chassis and 300 W or 500 W supplies are unchanged.

Its product guide still lists orderable processors, drives and regional models and gives no end-of-sale or end-of-service date. Machine type 7DF4 carries one year of base warranty and 7DF3 three, and longer cover can be bought from Lenovo Services; any date Lenovo publishes will appear in our end-of-life checker.
