Dense 1U dual-socket server

The Dell PowerEdge R640 packs two Intel Xeon Gold 6142 processors, each with 16 cores running at 2.6 GHz and a 3.7 GHz turbo frequency. It ships with 64 GB of DDR4-2666 registered ECC memory across 24 slots and supports up to 3 TB total. The PERC H730P controller manages eight 2.5-inch SATA or SAS drive bays with RAID levels 0, 1, 5, 6, 10, 50 and 60.

Verify rack depth and network cabling

Confirm your rack can accommodate a 1U chassis with included ready rails and front bezel. The system provides dual 1 GbE and dual 10 Gb SFP+ ports via an Intel X520/I350 daughter card, so plan for appropriate SFP+ transceivers and copper or fibre patch cables. iDRAC 9 Enterprise requires a dedicated management network connection for remote console and power control.

Dual 750 W platinum supplies share load

Redundant hot-swap 750 watt platinum power supplies operate in parallel, reducing per-unit strain and fan speed under typical workloads. The 1U form factor uses high-RPM internal fans that increase airflow across the CPUs, memory and storage controller; expect noticeable airflow noise in a quiet office but normal levels for a server room. Power draw scales with processor utilisation and installed drives.

Questions about this item

Does the server ship with any drives or do I need to purchase 2.5" SAS/SATA drives separately?

The unit includes eight 2.5" drive trays but no drives are installed; you must supply SAS or SATA drives yourself.

Is the installed 64 GB (4×16 GB) DDR4 2666 MHz the maximum memory or can I add more later?

The system has 24 DDR4 slots and supports up to 3 TB, so the current 64 GB can be expanded significantly.

What throughput can I expect from the PERC H730P 2 GB controller with SAS drives in a RAID array?

The H730P provides 12 Gb/s SAS connectivity and supports RAID 0, 1, 5, 6, 10, 50 and 60 for high-throughput storage.
