Dual-processor Xeon rack server

The Dell PowerEdge R640 arrives with two Xeon Silver 4215R processors running at 3.2 GHz and 128 GB of DDR4 ECC registered memory. It fits a standard 1U rack space and supports up to four 3.5-inch drive bays. This configuration targets IT teams building virtualisation hosts, database nodes or high-density compute clusters that need dual-socket performance in a compact form factor.

PERC H740P RAID controller

The bundled PERC H740P hardware RAID controller manages SATA drives with cache-backed data protection. A dual-port 10 GbE 562T network adapter is also installed, providing high-throughput connectivity for storage replication or VM migration. iDRAC9 Enterprise remote management is licensed, enabling out-of-band monitoring, firmware updates and power control without an operating system.

Verify rack depth and power infrastructure before

The chassis measures 36 inches deep, so confirm your cabinet can accommodate that length with cable clearance. Two 750 W power supplies are fitted; ensure your PDU circuits and plug types match the supplied units. Drive bays are empty, so source compatible 3.5-inch SATA drives and caddies separately. Rail kits are available on request but not included by default.

Spørgsmål om denne vare

What maintenance will the PERC H740P RAID controller and its battery-backed cache require over time?

The PERC H740P controller includes a battery-backed cache module that typically needs replacement every three to five years to protect data during power loss; the controller firmware is already updated to the latest stable version.

Which limit appears first when the dual Xeon Silver 4215R CPUs run at 3.2 GHz continuously?

Thermal limits are reached before power limits; the 2U chassis relies on high-speed fans to cool two 8-core processors and 128 GB of DDR4 ECC memory under sustained load.

How loud and how much power does the server draw with two 750 W supplies running all day?

Dual 750 W supplies provide redundancy; under full load the system can draw close to 750 W and fan noise rises to data-centre levels, so plan for a cooled rack environment.
