Dense 1U dual-socket server

The Dell PowerEdge R640 is a 1U rack server built for scale-out data center workloads. It ships with two Intel Xeon Gold 5118 processors, each running at 2.3 GHz with 12 cores. The system includes 256 GB of DDR4 registered ECC memory across eight 32 GB modules and eight 800 GB SATA SSDs managed by a PERC H730P RAID controller with 2 GB cache.

Suits virtualization and database clusters.

This configuration fits teams running virtualization, database clusters, or high-density web tiers that need dual-socket compute and fast local storage in a single rack unit. Buyers who need GPU acceleration for AI training or workstations with discrete graphics should look elsewhere. The 1U chassis and included rails support standard rack deployments, while iDRAC9 Enterprise provides remote management.

PERC H730P RAID controller with 2 GB cache

The installed PERC H730P controller supports RAID 0, 1, 5, 6, 10, 50, 60 and pass-through modes, backed by a battery-protected 2 GB cache. It manages the eight 800 GB SATA SSDs over a 12 Gb/s SAS/SATA interface. This controller choice determines the storage performance and data-protection options available without adding a separate HBA.

Questions about this item

What rack space and power connections do I need to install this 1U server?

The chassis occupies 1U of rack height and includes two 750 watt hot-swap power supplies; you must provide a rack with two available PDU outlets and the supplied rails.

Can the existing 800 GB SATA SSDs stay in place if I add more drives later?

The PERC H730P controller supports RAID 0, 1, 5, 6, 10, 50 and 60 across all eight 2.5 inch bays, so the installed SSDs remain usable while you populate empty slots.

How do I confirm the server is operating correctly once powered on?

iDRAC9 Enterprise will show a green system-health LED, both Xeon Gold 5118 CPUs at 2.30 GHz, 256 GB DDR4 at 2400 MHz and all eight 800 GB SSDs in a healthy RAID array.
