Dual-socket 1U rack server for dense compute

The Dell PowerEdge R640 fits two Intel Xeon Gold 6134 processors in a single rack unit. Each CPU runs at 3.2 GHz with eight cores and a 3.7 GHz turbo frequency. The system ships with 512 GB of DDR4 2666 MHz registered ECC memory across sixteen 32 GB modules. It targets workloads that need high core density and large memory capacity in a compact form factor.

Redundant 750 W platinum power supplies handle

Two hot-swap 750 watt platinum-efficiency units share the load and keep the server running if one fails. The 1U chassis uses front-to-back airflow to cool both processors and the twenty-four memory slots. Fan speed ramps with CPU utilisation so noise stays proportional to the actual thermal demand during normal operation.

Eight 2.5-inch drive bays with PERC H730P RAID

The front panel holds eight SAS/SATA bays populated with two 300 GB 10K SAS drives. The PERC H730P controller with 2 GB cache supports RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode. A quad-port network daughter card adds two 1 GbE and two 10 Gb SFP+ connections. iDRAC 9 Enterprise provides remote management, and ready rails with a front bezel are included for rack installation.

Questions about this item

How do I install the 2.5" SAS drives into the 8-bay front panel and seat them on the PERC H730P backplane?

Slide each drive into a front bay until the latch clicks, letting the connector engage the mid-plane that routes SAS lanes to the H730P; the step often missed is pressing the release button fully so the carrier locks and the activity LED lights.

What maintenance will the H730P RAID battery and the two 750W power supplies need later?

The H730P cache battery typically lasts three to five years and should be replaced when iDRAC9 reports a degraded state; each hot-swap 750W supply can be swapped independently without downtime if a fan or capacity warning appears.

Which limit appears first when both Xeon Gold 6134 CPUs run sustained 3.2 GHz workloads?

The 750W platinum power supplies set the thermal and current ceiling; before the CPUs hit their 3.7 GHz turbo, the platform power budget will throttle clocks to stay within the redundant supply rating.
