Dense 1U dual-socket server

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out workloads. It carries two Intel Xeon Platinum 8160 processors, each with 24 cores running at 2.1 GHz and a 3.7 GHz turbo. Memory is 64 GB of DDR4 2666 MHz registered ECC across four 16 GB modules. Storage uses a PERC H730P controller with eight 2.4 TB 10K SAS drives in 2.5 inch bays.

Compute-heavy scale-out workloads

This configuration suits buyers who need high core counts and fast local storage in a single rack unit, such as virtualisation clusters, database nodes or HPC front ends. It is not for buyers who want more storage bays than the eight 2.5 inch slots provide, or who need GPU acceleration that the 1U form factor cannot accommodate.

PERC H730P RAID controller

The storage controller is a Dell PERC H730P with 2 GB cache, supporting RAID 0, 1, 5, 6, 10, 50, 60 and pass-through. This single component determines which drive types, RAID levels and performance ceilings are available, so verify it matches the required storage topology before purchase.

Questions about this item

What does the 2.1 GHz base clock with 3.7 GHz turbo on the Xeon Platinum 8160 mean when the server is running real workloads?

The 2.1 GHz base clock is the guaranteed minimum frequency across all 24 cores per processor; under load the CPU can lift individual cores to 3.7 GHz when thermal headroom allows, so single-thread bursts run faster while sustained multi-core work stays at or above the base speed.

The PERC H730P is a 12 Gb/s SAS controller — what does that actually cap in daily use?

Each of the eight 2.4 TB SAS drives connects at up to 12 Gb/s, so the controller can move data to or from the array at the drives' full 10K RPM sequential rate; the practical ceiling is the combined throughput of the installed disks, not the controller link.

What physical mounting hardware comes with the 1U chassis so it can be installed in a rack?

The server ships with ready rails that slide into a standard four-post rack and a front bezel that snaps onto the chassis face; no additional brackets or shelf kits are required for a typical installation.
