1U Dual-Socket Server with 512GB DDR4

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out data center computing. It ships with two Intel Xeon Gold 6134 processors, each running at 3.20 GHz with eight cores. The system includes 512 GB of DDR4 2666 MHz registered ECC memory across 16 modules. Eight 300 GB 10K SAS drives and a PERC H730P controller provide the storage foundation.

Suited for Virtualisation and Database Workloads

This configuration fits environments that need high core counts and large memory capacity in a single rack unit. The dual 750 W platinum power supplies and iDRAC 9 Enterprise simplify remote management and uptime. Buyers who require more than 24 memory slots, additional drive bays beyond the eight 2.5-inch slots, or a different processor socket should evaluate other platforms.

PERC H730P RAID Controller with 2GB Cache

The installed Dell PERC H730P 2GB controller supports RAID 0, 1, 5, 6, 10, 50, 60 and pass-through modes at 12 Gb/s SAS and SATA speeds. A battery-backed cache protects data during power interruptions. This controller determines which drive types and RAID levels are available, so verify it matches your storage topology before purchasing.

Questions about this item

Should I pick the 8-core 3.2 GHz Xeon Gold 6134 or a higher-core model for dense virtualization?

The R640 ships with two Xeon Gold 6134 processors at 3.2 GHz base and 3.7 GHz turbo, each with 8 cores. That gives 16 total cores and 32 threads in a 1U chassis, which is the maximum CPU configuration this platform supports.

What does 512 GB of DDR4 2666 MHz ECC actually deliver in a running R640?

The system includes 16 modules of 32 GB DDR4-2666 registered ECC, filling 16 of the 24 DIMM slots. This provides 512 GB of error-correcting memory at the platform's rated speed, leaving 8 slots open for future expansion up to the 3 TB maximum.

How does the PERC H730P 12 Gb/s SAS controller limit drive performance?

The H730P 2 GB controller connects to the 8 front 2.5-inch bays at 12 Gb/s per lane and supports RAID 0, 1, 5, 6, 10, 50, 60 and pass-through. With the installed 300 GB 10K SAS drives the practical throughput ceiling is the drive spindle speed and the 12 Gb/s SAS link, not the controller itself.
