Dual-Socket 1U Rack Server

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out data centre computing. It ships with two Intel Xeon Gold 6148 processors running at 2.40 GHz with a 3.7 GHz turbo frequency. Each processor provides 20 cores, giving 40 cores total. The system includes 512 GB of DDR4 2666 MHz registered ECC memory across 16 modules.

Suited for High-Density Compute Workloads

This configuration suits environments that need maximum core count and memory capacity in a single rack unit. The 512 GB installed memory and dual 20-core CPUs support heavy virtualisation, database and high-performance computing tasks. Buyers who need more than 3 TB of total memory capacity or more than two processor sockets should look at larger platforms.

512 GB DDR4 Registered ECC Memory Installed

The server arrives with 512 GB of DDR4 2666 MHz registered ECC memory populated in 16 of the 24 available DIMM slots. This leaves eight slots free for future expansion up to the 3 TB maximum supported by the Intel C620 chipset. Memory type and speed must match DDR4 2666 MHz registered ECC specifications for compatibility.

Questions about this item

What SAS speed does the H730P controller support and what does that limit for the eight 300 GB drives?

The PERC H730P is a 12 Gb/s SAS controller, so the installed 300 GB 10K drives run at up to 12 Gb/s each.

What rack depth and mounting hardware does the 1U chassis require?

The server includes Dell Ready Rails for tool-less mounting in standard four-post racks; verify your rack depth matches the rail range.

How is the iDRAC9 Enterprise module accessed for the first time, and what step is often missed?

Connect a management cable to the dedicated iDRAC port, then configure a static IPv4 address via the LCD front panel or DHCP before browser login.
