Dense 1U dual-socket compute platform

The Dell PowerEdge R640 is a 1U rack server built for scale-out data-center workloads. It ships with two Intel Xeon Gold 6142 processors, each running at 2.6 GHz with 16 cores and a 3.7 GHz turbo frequency. The system includes 512 GB of DDR4 2666 MHz registered ECC memory across 16 DIMM slots, leaving eight slots open for future expansion.

Storage and networking interface limits

The PERC H730P controller provides 12 Gb/s SAS and SATA connectivity with 2 GB cache and battery backup, supporting RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode. Two 300 GB 10K SAS drives occupy two of the eight 2.5-inch drive bays. The Intel X520/I350 daughter card delivers two 1 GbE and two 10 Gb SFP+ ports for flexible network integration.

Enterprise-grade chassis with remote management

Redundant 750 W platinum-efficiency power supplies and hot-swap capability protect uptime during maintenance. iDRAC 9 Enterprise enables full out-of-band remote control, monitoring and firmware updates without physical access. The included ready rails and front bezel simplify rack installation, while the 1U height maximizes density for environments where space is at a premium.

Questions about this item

Should I pick the 512GB DDR4 configuration or add more modules up to the 3TB maximum?

The server ships with 512GB across 16 slots; 8 slots remain free for future expansion to the 3TB limit using DDR4 registered ECC modules.

What does the 2.6GHz base clock with 3.7GHz turbo mean for actual workload performance?

Each of the two Xeon Gold 6142 CPUs runs at 2.6GHz base and can boost to 3.7GHz, giving 32 total cores that scale frequency with thermal headroom.

How does the PERC H730P 12Gb/s SAS controller limit drive throughput in practice?

The H730P caps each SAS lane at 12Gb/s, so the installed 300GB 10K drives and any added SAS or SATA devices share that per-lane bandwidth ceiling.
