Dual 20-core Xeon Gold 5218R platform

This HPE ProLiant ML350 Gen10 rack server ships with two Intel Xeon Gold 5218R processors running at 2.1 GHz, delivering 40 cores in total. It is built for organisations that run virtualised workloads, databases or ERP systems on-premises and need room to grow inside a tower-convertible 4U chassis.

384 GB DDR4 ECC and Smart Array P408 controller

The installed 384 GB of DDR4 ECC registered memory protects data integrity across heavy multi-tenant workloads. The onboard HPE Smart Array P408 SAS controller manages up to eight 2.5-inch SATA drives, so storage can be added later without a separate RAID card purchase.

Maximum two processors and 3 TB memory ceiling

The board supports only two sockets and tops out at 3 TB of RAM, so buyers who anticipate scaling beyond 40 cores or 384 GB must choose a different platform. The integrated Intel I350 and X540 network adapters provide two 10 GbE and two 1 GbE ports for current connectivity needs.

Questions about this item

Will the 384GB DDR4 memory need to be replaced or expanded later?

The server holds 384GB DDR4 ECC registered memory now and supports up to 3TB total capacity across its slots, so additional modules can be added without removing the existing ones.

What limits sustained performance on the two Xeon Gold 5218R 2.1 GHz 20-core processors?

Each processor runs at 2.1 GHz with 20 cores and 27.5MB cache; thermal design power and chassis airflow become the first constraints during continuous all-core workloads.

How much noise and heat do the two 500W flex-slot power supplies produce when the system runs all day?

Dual 500W flex-slot supplies share the load, keeping fan speeds moderate; typical office ambient temperatures stay comfortable while power draw scales with the 40-core CPU configuration.
