Dual Xeon 4516Y+ 2U server
This 2U rack system ships with two Intel Xeon 4516Y+ processors, each running at 2.20 GHz with 24 cores and 45 MB of L3 cache. It targets organisations that need a dense, general-purpose platform for virtualisation, database or cloud workloads where dual-socket performance and hardware root-of-trust security are required.
1 TB DDR5-5600 with 4 TB ceiling
The server arrives with 1 TB of ECC DDR5-5600 RDIMM installed across 16 slots, leaving headroom to reach the 4 TB maximum when all channels are populated at one DIMM per channel. Memory bandwidth scales with the 5600 MT/s rate, while the single 240 GB SATA SSD covers only the boot volume; additional storage bays must be filled for data capacity.
Dual 1200 W Titanium power supplies
Two hot-swap 1200 W Titanium-level units provide redundant, high-efficiency power for the dual-CPU configuration and fully populated memory. The platform tops out at two processors, so buyers needing four-socket scaling or GPU-dense acceleration should evaluate alternative chassis.

Questions about this item
Will the dual Xeon 4516Y+ processors fit into a rack that currently holds single-socket servers?
The system occupies a standard 2U rack height, so it installs in the same space as any other 2U chassis; the dual-socket design does not change the external dimensions.
How can I confirm the 1 TB DDR5-5600 memory is running at full speed after first boot?
Check the BIOS memory information screen or the BMC dashboard — both report the configured DDR5 frequency per channel.
Does the box include rails for a four-post rack and extra drive caddies for the remaining bays?
The unit ships with the 240 GB SATA SSD installed, two 1200 W titanium power supplies, three hot-swap fans, and the TPM 2.0 module; rails and additional caddies are sold separately.
