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.

Questions about this item

How does the dual 8-core Xeon Silver 4108 at 1.80GHz behave when all 16 cores are loaded in a virtualization host?

The two processors give 16 physical cores at 1.80 GHz base frequency, so a hypervisor can schedule 16 concurrent vCPU threads without oversubscribing the hardware.

What does the H740P RAID controller limit for the installed 2.5-inch SSDs?

The H740P manages the two 512 GB SSDs and any additional 2.5-inch drives through its own firmware, capping array performance to the controller’s RAID implementation.

Will this 1U chassis accept full-height PCIe cards or only low-profile ones?

The 1U rack height restricts expansion to low-profile PCIe cards; full-height cards will not fit in the chassis.
