Dual-socket 1U server for dense scale-out

The PowerEdge R640 fits two Xeon Gold 6148 processors into a single rack unit. Each CPU runs at 2.4 GHz with 20 cores and a 3.7 GHz turbo frequency. The platform targets workloads that need high core counts in minimal space.

H730P controller and quad-port networking

The PERC H730P adds 2 GB cache and supports RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode. An Intel X520/I350 daughter card provides two 1 GbE and two 10 Gb SFP+ ports. iDRAC 9 Enterprise enables full remote management.

512 GB DDR4 across 16 slots filled

Installed memory uses 16 registered ECC modules at 2666 MHz, leaving eight DIMM slots open for expansion up to 3 TB. Buyers who need more memory capacity must add modules; the board accepts no other DDR generation.

Preguntas sobre este artículo

What maintenance will the PERC H730P RAID controller battery need?

The PERC H730P includes a battery-backed write cache; the battery is a field-replaceable unit that typically requires replacement every three to five years to preserve cache protection during power loss.

Which limit appears first when both Xeon Gold 6148 processors run at 3.7GHz turbo across all 20 cores continuously?

The 750W platinum power supplies set the first ceiling; sustained all-core turbo on both 20-core CPUs can exceed the redundant power budget before thermal throttling activates.

How loud are the fans and how much heat does the 1U chassis produce during 24/7 operation?

Six high-speed 40mm fans keep the 1U node within thermal limits; at full load they generate data-centre grade noise levels and exhaust several hundred watts of heat into the rack aisle.
