Dense 1U dual-socket platform

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out data center computing. It carries two Intel Xeon Gold 6134 processors at 3.2 GHz with 3.7 GHz turbo and eight cores each. Memory is 64 GB of DDR4 2666 MHz registered ECC across four 16 GB modules. The system targets workloads that need high core count in minimal rack space.

Redundant 750 W platinum power and thermal design

Dual 750 watt platinum-efficiency hot-swap power supplies provide redundancy for continuous operation. The 1U chassis uses forced-air cooling tuned for the installed CPU and memory configuration. Power draw and acoustic output scale with the two 8-core processors and the storage controller under typical data center loads.

PERC H730P RAID and quad-port networking included

The Dell PERC H730P 2 GB controller supports RAID 0, 1, 5, 6, 10, 50, 60 and pass-through for the two 400 GB SATA SSDs. A quad-port Intel X520/I350 daughter card adds two 1 GbE and two 10 Gb SFP+ connections. iDRAC 9 Enterprise enables remote management, while ready rails and a front bezel simplify rack installation.

Questions about this item

How do I install the 2.5-inch SSDs and what step is often missed?

Slide each SSD into an 8-bay 2.5-inch hot-swap tray until the latch clicks; the step people miss is confirming the PERC H730P 2GB controller detects both 400GB SATA drives in the RAID BIOS before loading the OS.

What maintenance or replacement will the PERC H730P controller need later?

The controller includes a battery-backed cache; plan to replace the cache battery module when iDRAC 9 Enterprise reports a battery-learn cycle failure or degraded write-back performance.

What limit appears first under sustained heavy write workloads?

The two 400GB SATA SSDs will hit their write-endurance ceiling before the dual 750-watt platinum power supplies or the 2666 MHz DDR4 memory bandwidth become bottlenecks.
