Dense Virtualization Platform

This 1U rack server targets IT teams running hypervisors, databases and transaction-heavy workloads in space-constrained racks. Dual Xeon Gold 6136 processors deliver 24 cores and 48 threads at 3.00GHz to keep multiple virtual machines responsive. 128GB of DDR4 ECC memory supports consolidated services without constant swapping. Eight hot-swap 1.2TB 10K SAS drives provide fast local storage for active datasets.

Thermals and Power Profile

The 1U chassis moves air front-to-back through a dense component layout designed for continuous operation in climate-controlled aisles. Dual 350W and 540W power supplies share load, reducing strain on any single unit during sustained compute bursts. Fan curves react to inlet temperature and CPU utilisation, keeping acoustic output predictable in a server-room context. Integrated GPU and dual-port 10GbE plus 1GbE NICs draw modest additional power under typical virtualization traffic.

Build and Connectivity Reality

Eight 2.5-inch bays are fully populated, leaving no internal room for extra drives without external enclosures. The PERC H740P controller manages RAID across all bays from a single interface, simplifying volume changes during maintenance windows. Dual 10GbE X540 and dual 1GbE I350 ports give flexible uplink options for storage fabrics and management networks. Front-panel LEDs for power, Ethernet and USB provide at-a-glance status without a crash cart. Buyers needing more than 128GB RAM or additional PCIe slots should plan for a 2U alternative.

Preguntas sobre este artículo

How do I install the 2.5" SAS drives and which step is often missed?

Slide each 1.2TB 10K drive into the hot-swap bay until the latch clicks; the step often missed is creating the virtual disk in the H740P BIOS before the OS sees the array.

What maintenance will the 128GB DDR4 ECC memory need later?

DDR4 ECC Registered modules are solid-state and require no scheduled replacement; only a failed DIMM would need swapping, and the system supports up to 3TB total capacity.

What limit appears first when the dual Xeon Gold 6136 CPUs run sustained loads?

The 3.00GHz base frequency across 24 cores and 48 threads is the thermal ceiling; prolonged full-load work will hit the cooling capacity of the 1U chassis before any other bottleneck.
