What is the maximum memory of the HPE ProLiant ML30 Gen11?
The ML30 Gen11 takes 128 GB: four DDR5 ECC UDIMM slots filled with 32 GB modules. HPE sells only 16 GB and 32 GB unbuffered kits; RDIMMs, LRDIMMs and non-ECC modules are unsupported. HPE’s memory rules cap the modules at 4400 MT/s, although the Standard Features line quotes the 128 GB maximum at 4800 MT/s; for Xeon E and Pentium processors its table falls to 4000 or 3600 MT/s once both slots of a channel are filled.
Which processors does the ML30 Gen11 support?
A single processor, picked from eighteen: nine Xeon 6300 models with 4–12 cores, eight Xeon E-2400 models with 4–8 cores, or the two-core Pentium G7400. Power ratings span 46–95 W, and the 95 W models need the high-performance heat sink kit. The top option is the 12-core Xeon 6377P, added in Version 27 of the QuickSpecs.
How many drives does the ML30 Gen11 hold?
Up to eight. The server comes as one of three chassis: four 3.5-inch non-hot-plug SATA bays, four 3.5-inch hot-plug SAS/SATA bays, or eight 2.5-inch hot-plug SAS/SATA bays. There are no NVMe bays; NVMe is limited to the NS204i-u boot device or a single M.2 slot on an optional kit.
Can the ML30 Gen11 take a GPU?
HPE lists two NVIDIA cards, the RTX A400 with 4 GB and the RTX A1000 with 8 GB, but does not state how many can be fitted or their power. Either card switches off the iLO video port, leaving the iLO web GUI for remote console use. Version 27 of the QuickSpecs removed the GPU power cable kit and some obsolete accelerator SKUs.
How many PCIe slots does the ML30 Gen11 have?
Four full-height slots. Slot 1 is PCIe 5.0 x16 and slot 2 is PCIe 4.0 with four lanes, both from the processor; slots 3 and 4 are half-length PCIe 4.0 x4 slots on the PCH. There is no OCP slot, and SAS controllers compete with Gen5 x16 cards for slot 1.
Does the ML30 Gen11 have redundant power supplies?
Only if you choose it. The entry option is a single 350 W ATX supply with no redundancy. For 1+1 redundancy, fit two identical hot-plug Flex Slot units — 500 W Platinum, 800 W Titanium or 1000 W Titanium — together with the RPS Enablement Kit; the 800 W unit needs 200–240 VAC.
Is the ML30 Gen11 quiet enough for an office, and how big is it?
HPE declares 22 dBA at the bystander position for its Entry model and 24 dBA for its Performance model, idle and operating, measured at 23 °C; added options can raise that. The tower is 36.83 cm high, 17.53 cm wide and 47.50 cm deep, and weighs 10.2 kg in its lightest build and 18.7 kg fully loaded.
Can the ML30 Gen11 be rack-mounted?
Only by way of a shelf. The Overview names sliding shelf 874578-B21 as the optional route to a rack form factor; in the option list that part is HPE’s ML Gen10 tower-to-rack conversion kit, a sliding rail tray with cable management arm that occupies 1U. Its note says it gives shelf function for the ML30 Gen10 Plus, so confirm Gen11 fit with HPE before ordering. HPE describes the ML30 Gen11 itself only as a 4U tower.
Should I choose the ML30 Gen11, the MicroServer Gen11 or the ML110 Gen11?
The MicroServer Gen11 uses the same processor families and 128 GB memory limit in a 15.4 cm-tall chassis, but has four non-hot-plug bays, two low-profile slots and an external power adapter. The ML30 adds hot-plug bays, four full-height slots and redundant supplies. The ML110 Gen11 moves to Xeon Scalable processors, sixteen RDIMM slots and up to sixteen SFF bays.
Is the HPE ProLiant ML30 Gen11 end of life?
Not according to HPE’s own document: Version 27 of the ML30 Gen11 QuickSpecs, dated 3 August 2026, still adds processors and carries no end-of-sale or end-of-support date — the only withdrawals it records are obsolete option SKUs. For the latest lifecycle status, run the model through our server end-of-life checker.
