Built for dense virtualisation and database clusters

This 2U rack server ships with two Intel Xeon Gold 6338 processors, each running at 2.0 GHz with 32 cores and a 3.2 GHz turbo frequency. The dual-socket design targets organisations that need high thread counts for virtualisation hosts, in-memory databases or analytics workloads. Buyers who require GPU acceleration or single-thread optimisation should look elsewhere.

Memory capacity and headroom

The system includes 128 GB of DDR4 3200 MHz registered ECC memory populated across 8 of the 32 available DIMM slots. This leaves significant headroom for future expansion without replacing existing modules. Workloads that exceed the installed capacity will need additional DDR4 sticks; the platform does not support other memory generations.

Thermals and power in normal use

Dual 1400 W platinum-efficiency power supplies provide full redundancy for the 24-drive array, dual CPUs and networking card. Hot-swap power and the 2U airflow design keep temperatures stable under sustained multi-core load. Acoustic output is typical for rack-density equipment and assumes a cooled data-centre environment.

Questions about this item

Will the 24-bay 2.5-inch SATA backplane accept my existing 3.5-inch SAS drives?

The chassis holds 24 front 2.5-inch bays wired for SATA; 3.5-inch drives will not fit and SAS drives are not supported by this backplane.

How can I verify the PERC H755 controller sees all 24 SSDs and the 8GB NV cache is healthy?

Open iDRAC9 Enterprise, navigate to Storage > Controller H755, and confirm 24 drives show Ready with the cache status reporting Optimal.

Which items ship with the server and what must I source separately for a working install?

Included: 2x Xeon Gold 6338 CPUs, 128GB DDR4 RDIMMs, 24x 960GB SSDs, H755 RAID card, 57412 dual 10GbE SFP+ OCP 3.0 NIC, iDRAC9 Enterprise, 2x 1400W PSUs, rails and bezel. Add SFP+ transceivers and fibre patch cables for network links.
