Dual Xeon Silver 4114 server

The Dell PowerEdge R640 is a 1U rackmount server built for business workloads such as virtualization, databases, and application hosting. It ships with two Intel Xeon Silver 4114 processors, each running at 2.20GHz with ten cores. The system includes 128GB of DDR4 ECC Registered memory and a PERC H740P RAID controller with 8GB cache. It is suited for IT teams deploying private clouds or high-availability clusters.

20 cores and 40 threads total

The dual-processor configuration delivers a combined twenty cores and forty threads at a 2.20GHz base frequency. This core count is the primary factor for sizing virtual-machine density and database concurrency. Both CPU sockets are populated, so the server cannot accept additional processors. Buyers needing higher single-thread frequency or more than twenty cores should evaluate other platforms.

128GB DDR4 scalable to 1.5TB

The installed 128GB of DDR4 ECC Registered memory supports multiple services and virtual machines out of the box. Memory capacity can be expanded up to 1.5TB using the available DIMM slots for larger datasets. Eight 2.5-inch hot-swap drive bays with included trays provide flexible storage, though drives are not supplied. The H740P controller manages SAS arrays for redundancy and performance.

Perguntas sobre este artigo

What does 20 cores at 2.2GHz mean for a virtualization host?

Two Xeon Silver 4114 CPUs give 20 cores and 40 threads total, providing enough parallel threads to run many virtual machines simultaneously.

How does the H740P controller limit drive performance?

The PERC H740P uses a 12Gbps SAS interface with 8GB cache, so drive throughput is capped at the SAS link speed rather than PCIe.

Will the 8-bay chassis accept 3.5-inch drives?

No, the R640 8B has eight 2.5-inch hot-swap bays with trays included; 3.5-inch drives will not fit.
