DELL PowerEdge R640 rack server 2x Xeon Silver 4108 1.80GHz 16-Core 64GB DDR4 2x 512GB SSD H740P RAID

Dense 1U rack server for virtualisation

The Dell PowerEdge R640 fits a dual-socket Intel Xeon Silver 4108 configuration into a single rack unit, delivering sixteen cores at 1.80 GHz with 64 GB of DDR4 memory for consolidation workloads. Two 512 GB SSDs and an integrated H740P RAID controller provide managed storage for operating systems, virtual machines and business data. Eight 2.5-inch drive bays allow further expansion without leaving the 1U footprint.

Dual-socket limit and fixed sixteen-core count

Only two processors can be installed and both sockets are already populated with eight-core Xeon Silver 4108 CPUs, so total core count cannot exceed sixteen. Memory currently sits at 64 GB DDR4 and the board uses LGA 3647 sockets, so any upgrade must match that platform. Buyers needing more than sixteen cores or a different processor generation must choose another chassis.

Steady throughput from H740P RAID and dual SSDs

The H740P controller manages the mirrored 512 GB SSDs with hardware RAID, sustaining consistent I/O for databases and backup jobs rather than relying on burst cache alone. Sixteen cores at a modest 1.80 GHz clock maintain predictable performance under continuous virtualisation loads while staying within the 1U thermal envelope. Workloads that demand higher single-thread frequency or GPU acceleration will not be served by this configuration.
