1U dual-socket server for dense compute

This new Dell PowerEdge R640 is a 1U rack server built for dense scale-out workloads. Two Intel Xeon Platinum 8160 processors run at 2.1 GHz with 24 cores each. The system includes 64 GB of DDR4 registered ECC memory and a PERC H730P controller with battery-backed cache. Eight 600 GB 10 K SAS drives and quad-port 1 GbE plus dual 10 GbE networking come pre-installed.

Suits virtualisation and database clusters.

The dual-socket design and 24 memory slots support up to 3 TB of DDR4, fitting virtualisation hosts and in-memory databases. Redundant 750 W platinum power supplies and iDRAC9 Enterprise simplify fleet management. The 1U chassis has no room for full-height accelerators, so buyers who need GPU compute should look elsewhere. Storage bays accept only 2.5-inch SAS or SATA drives.

PERC H730P controller decides RAID flexibility

The installed PERC H730P 2 GB controller provides 12 Gb/s SAS connectivity and supports RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode. Battery-backed cache protects in-flight writes during power loss. If your deployment requires a different RAID feature set or an HBA-only mode, this controller choice determines whether the server matches the requirement.

Questions about this item

What rack depth and rail kit does the 1U PowerEdge R640 require?

The server is a 1U rack-mount unit and ships with ready rails for standard four-post racks.

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

Two Xeon Platinum 8160 processors are pre-installed in the LGA 3647 sockets; the 64 GB DDR4 memory occupies four of the 24 slots as 16 GB registered ECC modules.

Which components will need replacement first — drives, batteries or power supplies?

The eight 600 GB 10K SAS drives and the PERC H730P controller battery are the primary wear items; the dual 750 W redundant power supplies are hot-swappable for later replacement.
