1U rack server for virtualisation and databases

The Dell EMC PowerEdge R640 fits a 1U rack slot and runs two Xeon Silver 4114 processors at 2.20 GHz with 20 cores total. Sixty-four gigabytes of DDR4 ECC registered memory support multiple virtual machines and business applications. Eight 1.2 TB SAS hard drives connect through a Perc H740P controller with 8 GB cache for storage of operating systems, databases and backups.

Check rack space, power and memory growth

Confirm the rack can accept a 1U chassis and provides redundant hot-swap power connections. The system uses LGA 3647 sockets with both processor positions filled, so CPU upgrades are not possible. Twenty-four DDR4 slots allow expansion up to 3 TB if workloads demand more memory. Four RJ45 ports deliver 1 GbE connectivity for network integration.

Dual power supplies and dense drive cooling

Redundant hot-swap power supplies share the load and keep the server running if one unit fails. The 1U height packs eight 10K SAS drives close to the processors, so airflow moves across memory, controller and storage simultaneously. Fan speeds adjust automatically to maintain thermal limits under typical virtualisation and database workloads.

Questions about this item

Does the server include the 8× 1.2 TB SAS drives and H740P controller, or must I buy them separately?

The unit ships with eight 1.2 TB 10K SAS drives and the Perc H740P 8 GB RAID controller already installed.

Should I choose the 64 GB DDR4 configuration or add more modules up to the 3 TB maximum?

Start with the installed 64 GB ECC registered DDR4; the 24 slots allow expansion later if workloads demand more capacity.

What does the 2.2 GHz base clock with 3.50 GHz Turbo mean for real-world virtualization performance?

Each Xeon Silver 4114 runs at 2.20 GHz base and can boost to 3.50 GHz, giving 20 total cores for concurrent VMs and database threads.
