Dense 1U Dual-Socket Server

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out deployments. It carries two Intel Xeon Silver 4116 processors, each with 12 cores running at 2.1 GHz and a 3.0 GHz turbo. The system includes 768 GB of DDR4 2400 MHz registered ECC memory across 24 slots and eight 400 GB SATA SSDs managed by a PERC H730P controller.

Virtualisation and Database Workloads

This configuration suits virtualisation hosts, database nodes and high-performance computing clusters that benefit from 24 total cores and a large memory footprint. The quad-port network daughter card provides two 1 GbE and two 10 Gb SFP+ connections for flexible fabric integration. Buyers who need more than two processors or storage interfaces beyond SATA and SAS should evaluate other platforms.

768 GB DDR4 Registered ECC Memory

The installed 768 GB of DDR4 2400 MHz registered ECC memory fills all 24 DIMM slots and determines the maximum capacity available without adding modules. The platform supports up to 3 TB when higher-density DIMMs are used. Matching this memory type and speed is essential for any future expansion or replacement.

Questions about this item

What is the maximum RAID level the PERC H730P controller supports?

The PERC H730P supports RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode with its 2GB cache and battery backup.

What does the server need to mount in a rack?

It ships with Dell Ready Rails and a front bezel; the rails are designed for tool-less installation in standard 4-post racks.

How are the CPUs installed, and what step is often missed?

Two Xeon Silver 4116 processors come pre-installed in the LGA 3647 sockets; the common oversight is not updating the system BIOS and iDRAC firmware before first use.
