Chassis options

The ML350 Gen9 comes as a tower or a rack model, and a tower can be converted later with the HPE Tower to Rack Conversion Kit. Within each, the chassis is either small form factor (SFF, 2.5-inch) or large form factor (LFF, 3.5-inch); this is fixed at purchase. Each drive cage holds eight hot-plug bays, and further cages can be added.

The capacities are HPE's figures from the December 2015 QuickSpecs. Fans are three as standard on a single-processor model and four with two processors; redundant fan kits take those to six and eight. An optional DVD-ROM or DVD-RW drive fits the media bay, and the rack model can take a System Insight Display and a security bezel.

Processors

One or two Intel Xeon E5-2600 v3 processors (the Haswell-EP generation) on the Intel C610 chipset. The second processor is optional and brings the second bank of twelve DIMM slots and PCIe slots 5 to 9 into use. Both processors must match. HPE's QuickSpecs list the following options, with the memory speed each processor supports; a system with two 18-core processors reaches 36 cores.

The QuickSpecs edition we hold (Version 10, December 2015) lists the v3 generation only. HPE later qualified the E5-2600 v4 generation on Gen9 servers with a system ROM update; if v4 matters to you, tell us and we will confirm against the specific unit rather than assume.

Memory

Twenty-four DDR4 DIMM slots, twelve per processor, arranged as four channels per processor with three slots per channel. HPE SmartMemory registered (RDIMM) or load-reduced (LRDIMM) modules are supported, with Advanced ECC and online spare memory protection.

HPE's population rules matter here: do not mix RDIMMs and LRDIMMs; quad-rank RDIMMs are not supported; with one processor only half the slots are available; balance capacity across the two processors and load channels evenly. Mixed-speed modules run at a common speed, and the final speed depends on the processor model as the table above shows. Total memory is capped at 1 TB when one of the NVIDIA graphics options is fitted. Our server memory range covers DDR4 RDIMMs and LRDIMMs; send the serial number and we confirm the fit.

Storage and RAID

Entry models ship with the embedded HPE Dynamic Smart Array B140i software RAID; base and performance models ship with the HPE Flexible Smart Array P440ar with 2 GB flash-backed write cache, which connects eight internal drives without using a PCIe slot. The B140i cannot be used once a P440ar or H240ar is fitted. The QuickSpecs list these options:

To go beyond eight drives the HPE 12Gb SAS Expander Card supports 24 drives, and it must be paired with a P440, P840 or H240 card: the flexible-slot P440ar and H240ar cannot connect to it. Drives are 12 Gb/s SAS or SATA hard drives and SSDs in HPE's Gen9 hot-plug carriers, and NVMe is possible on the SFF chassis through the 6 SFF Express Bay enablement kit, one per server, with its bridge card in slot 3, 6 or 8 (slots 6 and 8 need the second processor). Our SAS hard drives and RAID controllers ranges cover this platform; send the serial number and we confirm the carrier and controller before shipping.

Networking and expansion

Networking is the embedded HPE 1Gb Ethernet 4-port 331i adapter, four RJ-45 ports, plus a dedicated 1 Gb iLO management port. Nine expansion slots are fitted, eight PCIe 3.0 and one PCIe 2.0; slots 5 to 9 are only active with a second processor.

Slots 1 and 3 on the first processor, and 6 and 8 on the second, can carry a graphics accelerator. The QuickSpecs list the NVIDIA Quadro K2200, K4200, K5200, K6000 and M6000 and the Tesla K40c, supported on 64-bit Linux and Windows. Other ports: one serial, one VGA (Matrox G200 graphics), five USB 2.0 (two front, two rear, one internal), three USB 3.0 (two rear, one internal) and an internal microSD slot. Ask before ordering a card so we can check slot, power and memory limits for the unit.

Power supplies

HPE Flex Slot hot-plug power supplies, with bays for up to four at the rear. The options are 500 W Platinum, 800 W Platinum and 1400 W Platinum Plus, all accepting 100 to 120 V or 200 to 240 V AC. Standard entry models ship with a single 500 W unit; a second supply of the same rating gives redundancy. HPE notes that the 500 W unit is not supported with the four-supply enablement kit, so plan on 800 W or 1400 W if you want more than two supplies. Tell us the build and we will size the supply.

Management

HPE Integrated Lights-Out 4 (iLO 4) is embedded with 4 GB of NAND and a dedicated management port. It gives remote power control, health monitoring and alerting as standard; the optional iLO Advanced licence adds the remote console and virtual media. Intelligent Provisioning is built in for firmware, driver and OS deployment without external media. The iLO RESTful API conforms to Redfish 1.0 from iLO firmware 2.30 onwards. The server is IPMI 2.0 compliant and boots in UEFI mode by default, with legacy BIOS mode available.

Physical specification

HPE declares bystander sound pressure of 19 to 21 dBA at idle and 21 to 28 dBA operating, depending on the configuration, which is quiet enough for a shared office.

Supported operating systems

HPE's QuickSpecs list Microsoft Windows Server, Canonical Ubuntu, Red Hat Enterprise Linux, SUSE Linux Enterprise Server, VMware and Citrix XenServer, and point to the HPE support matrix for versions. The document dates from 2015, so check the current matrix for the release you intend to run and ask us if a specific hypervisor version is a requirement.

Buying a refurbished HPE ProLiant ML350 Gen9 from ServerDove

ServerDove holds ML350 Gen9 systems in Doha and tests every refurbished unit before it is listed. Our systems are supplied configured, typically with registered DDR4 memory and hot-plug SAS hard drives fitted, and we can change the processors, add memory, fit a Smart Array controller with cache, add drive cages or supply the rack conversion kit on request. Parts not on the site can be sourced. Hardware is covered by the ServerDove warranty, with extended cover quoted on request. Delivery across Qatar is typically one day from Doha stock, and installation, cabling, base configuration and rack conversion are available as a service.
