Dense compute platform

This 1U rack server delivers dual-socket Intel Xeon Gold 6134 performance in a single rack unit. Two 8-core processors run at 3.2 GHz with 3.7 GHz turbo for dense scale-out workloads. The system ships with 256 GB of DDR4 2666 MHz registered ECC memory across 8 populated slots. A PERC H730P controller and quad-port 1/10 GbE networking complete the configuration.

Suits virtualisation and database clusters

Organisations consolidating virtual machines or running memory-intensive databases gain from the 24 DIMM slots supporting up to 3 TB total capacity. Redundant 750 W platinum power supplies and hot-swap 2.5" bays maintain uptime during maintenance. Buyers who need more than eight drive bays or a different storage controller should evaluate other platforms.

Eight hot-swap 2.5" bays define storage limits

The chassis provides exactly eight SAS/SATA drive slots populated with two 300 GB 10 K SAS disks. RAID 0, 1, 5, 6, 10, 50 and 60 are supported by the H730P with its 2 GB cache. Expanding beyond eight drives requires an external enclosure or a different server model.

Questions about this item

How do I install the server into a rack, and what step do people often miss?

Use the included Ready Rails to mount the 1U chassis, then insert the eight 2.5" drive carriers into the front bays and connect the SAS cables to the PERC H730P controller before powering on.

Which components will need replacement or maintenance during the server's life?

The two 300GB 10K SAS hard drives and the PERC H730P controller's battery-backed cache are the primary field-replaceable items; the 750W platinum power supplies are hot-swappable if a unit fails.

What limit appears first when the server runs sustained workloads?

The 256GB DDR4 2666MHz memory capacity across 24 slots is the first ceiling; the Xeon Gold 6134 CPUs support up to 3TB, so adding registered ECC modules extends headroom before CPU or thermal limits bind.
