Dell PowerEdge R640 10-bay virtualization server

The Dell PowerEdge R640 is a 2U rackmount server system built for business workloads. Two Intel Xeon Gold 6148 processors deliver 40 total cores at 2.40GHz. The system includes 128GB of DDR4 memory and a PERC H730P storage controller. Ten 2.5-inch drive bays are populated with 1TB SATA SSDs.

Suited for virtualization.

This configuration supports file storage, virtualization, databases, backups and application hosting. The 128GB DDR4 capacity and 10TB of SSD storage fit multi-service deployments. Buyers needing GPU acceleration for compute workloads should look elsewhere because only integrated graphics are present. The maximum of two processors is already installed, so no further CPU expansion is possible.

10-bay 2.5-inch chassis with H730P controller

The 10-bay 2.5-inch front chassis determines how many drives can be installed and connects them to the included H730P RAID controller. Ten 1TB SATA SSDs fill every bay, so adding more internal storage requires removing existing drives. The H730P manages RAID levels and simplifies day-to-day storage administration.

Questions about this item

Does the H730P controller become a bottleneck when all ten 2.5-inch bays are filled with SATA SSDs?

The H730P controller manages all ten 2.5-inch bays, so sustained throughput depends on its PCIe lane allocation and the combined SSD workload.

How loud do the fans get when both Xeon Gold 6148 CPUs run at 2.40GHz continuously?

Dual 24-core Xeon Gold 6148 processors at 2.40GHz draw significant power, so the 1U chassis fans ramp up to maintain thermal limits under full load.

Which DDR4 modules must I already have to reach the 3TB maximum memory capacity?

Reaching 3TB requires populating all DIMM slots with high-capacity DDR4 LRDIMMs or 3DS RDIMMs that the platform qualifies.
