Dual-Socket 1U Server for Dense Scale-Out Computing

The PowerEdge R640 is a 1U rack server built for dense scale-out data center workloads. It delivers dual-socket performance in a compact form factor. This system targets IT teams running virtualization, database or high-performance computing clusters where rack density matters.

40 Cores at 2.4 GHz with 3.7 GHz Turbo

Two Intel Xeon Gold 6148 processors provide 20 cores each at a base frequency of 2.4 GHz and a maximum turbo of 3.7 GHz. The LGA 3647 socket and Intel C620 chipset support up to two processors total. This core count and clock profile determines whether the server matches your thread-heavy application requirements.

Tool-Less Rails and Hot-Swap Components Simplify

Included Ready Rails enable tool-less mounting in standard 4-post racks. Redundant 750 W hot-swap power supplies and the front 8-bay 2.5" drive cage allow component replacement without downtime. The PERC H730P controller battery must be seated correctly or the array will default to write-through mode, degrading write performance. iDRAC9 Enterprise provides remote console access for headless management.

Frågor om den här produkten

What does 2.4 GHz mean once the Xeon Gold 6148 CPUs are running real workloads?

The two Xeon Gold 6148 processors run at a 2.4 GHz base frequency and can boost to 3.7 GHz on up to 20 cores each, giving 40 threads of compute capacity for dense scale-out tasks.

What does the PERC H730P controller cap in practice?

The PERC H730P provides 12 Gb/s SAS connectivity and supports RAID 0, 1, 5, 6, 10, 50 and 60 with a 2 GB cache, so the controller itself sets the maximum array throughput and RAID level options.

What does the 1U chassis need to fit in a rack?

The server occupies a single 1U rack space and ships with ready rails and a front bezel for mounting in a standard four-post rack.
