Platform summary

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out workloads. Two Intel Xeon Gold 6134 processors run at 3.2 GHz with eight cores each. Sixty-four gigabytes of DDR4 2666 MHz registered ECC memory are installed across four modules. Eight 400 GB SATA SSDs provide high-speed storage in a 2.5 inch form factor.

Fit and limits

This server suits deployments that need dual-socket compute in a single rack unit with integrated RAID and remote management. Buyers who require more than 3 TB of memory, additional drive bays beyond eight, or a taller chassis for extra expansion cards should evaluate other platforms. The PERC H730P controller supports RAID 0, 1, 5, 6, 10, 50 and 60 with a 2 GB cache battery.

Deciding specification

The installed memory capacity is 64 GB DDR4 with a maximum of 3 TB across twenty-four slots. If the target workload fits within 64 GB today and can grow later, this configuration is appropriate; if the application demands the full 3 TB immediately, additional modules must be sourced before deployment.

Questions about this item

How do I choose between the installed 400 GB SSDs and larger drives?

The server ships with eight 400 GB SATA SSDs; the backplane accepts 2.5" SATA or SAS drives, so you can add larger capacities up to the 24-slot memory limit for storage expansion.

What does the 3.2 GHz base clock mean for actual workloads?

Each Xeon Gold 6134 runs at 3.2 GHz base and can boost to 3.7 GHz, giving two 8-core processors strong single-thread speed for database or virtualization tasks.

What does the PERC H730P 12 Gb/s controller cap in practice?

The H730P supports 12 Gb/s SAS and 6 Gb/s SATA, so the eight 6 Gb/s SSDs run at their native SATA speed while the controller handles RAID 0, 1, 5, 6, 10, 50, 60.
