Dual 14-core Xeon Gold 6148 server

The Dell PowerEdge R640 is a 1U rackmount server fitted with two Intel Xeon Gold 6148 processors. Each CPU runs at 2.40 GHz with 14 cores, giving a total of 40 cores across the system. It ships with 512 GB of DDR4 memory and an H730P storage controller. The chassis provides eight 2.5-inch drive bays.

Virtualisation and database workloads

This configuration suits organisations running virtual machines, databases or file storage on a single dense node. The 512 GB memory ceiling and dual-socket design support heavy multi-tenant workloads. Buyers who need GPU acceleration or more than eight drive bays should look at a different platform.

3 TB maximum DDR4 capacity

The motherboard accepts up to 3 TB of DDR4 across its memory slots. The installed 512 GB leaves headroom for growth without replacing modules. Verify that your application fits within this limit before committing.

Questions about this item

What comes with the Dell PowerEdge R640 and do I need to buy drives separately?

The server includes two Xeon Gold 6148 processors, 512GB DDR4 memory, an H730P storage controller, eight 2.5" drive trays, rack rails and a front bezel. Storage drives are not included and must be purchased separately.

Should I choose a different CPU or memory configuration for heavier virtualization?

This unit already has the maximum two Xeon Gold 6148 CPUs (40 cores total) and 512GB DDR4 installed. Memory can be expanded up to 3TB if your workloads require more capacity.

What does the 40-core figure mean for real-world virtualization performance?

With two 14-core Xeon Gold 6148 processors running at 2.4GHz, the 40 logical cores provide strong multi-threaded throughput for running many virtual machines or container workloads simultaneously.
