Dense 1U dual-socket server

The PowerEdge R640 fits two Xeon Gold 6148 processors into a single rack unit, delivering 40 cores at 2.4 GHz with a 3.7 GHz turbo frequency. It targets organisations that need high compute density for virtualisation, database or high-performance workloads in space-constrained racks. Buyers who require GPU acceleration or more than two sockets should look elsewhere.

H730P controller and quad-port networking

The PERC H730P with 2 GB cache enables RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode for the two installed 800 GB SATA SSDs. An Intel X520/I350 daughter card adds two 1 GbE and two 10 Gb SFP+ ports without consuming a PCIe slot. iDRAC 9 Enterprise provides dedicated remote management.

Verify rack depth and power infrastructure

Confirm the cabinet can accommodate the chassis depth and that dual 750 W platinum supplies match available PDU outlets and circuit capacity. Ensure SFP+ transceivers and fibre patch cables are on hand for 10 Gb links. Memory uses DDR4 registered ECC DIMMs; other generations will not fit.

Pitanja o ovom artiklu

When will the PERC H730P RAID controller battery need replacing?

The PERC H730P includes a 2 GB cache battery that typically lasts three to five years; plan replacement when iDRAC 9 Enterprise reports a degraded state.

What thermal limit appears first when both Xeon Gold 6148 CPUs run at 3.7 GHz turbo continuously?

The 750 W platinum power supplies and 1U airflow design set the ceiling; sustained turbo on all 40 cores will hit the platform power budget before CPU junction temperature becomes the bottleneck.

How loud are the fans when the server idles at 768 GB DDR4 2666 MHz memory capacity?

Idle fan speed is governed by iDRAC 9 Enterprise thermal policies; with redundant 750 W PSUs and fully populated DIMM slots the acoustics stay in the typical 1U rack range for this platform.
