Dual-socket 1U server for dense compute

The PowerEdge R640 packs two Xeon Gold 6148 processors, each with 20 cores at 2.4 GHz and 3.7 GHz turbo, into a single rack unit. 512 GB of DDR4 registered ECC memory fills 16 of the 24 available slots. Eight 800 GB SATA SSDs provide fast local storage behind a PERC H730P controller with 2 GB cache.

Verify rack depth and network cabling

The chassis uses 2.5-inch drive bays and includes ready rails for standard four-post racks. Confirm the rack can accommodate the server depth and that SFP+ transceivers or direct-attach cables are on hand for the dual 10 GbE ports on the X520/I350 daughter card. Dual 750 W platinum power supplies require matching PDU outlets.

Hot-swap redundancy frees maintenance windows

Redundant power supplies and hot-swap drive carriers let you replace failed components without shutting down the host. iDRAC 9 Enterprise gives remote console, power control and hardware inventory over a dedicated management port. The PERC H730P supports RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through for software-defined storage.

Questions about this item

Does the server ship with all eight 2.5-inch drive bays filled, or do I need to buy additional SSDs?

Eight 800 GB SATA SSDs are already installed, one in every 2.5-inch bay, so no extra drives are required.

The listing shows two Xeon Gold 6148 processors — is that the maximum this model can take?

Yes, the R640 supports a maximum of two processors and both sockets are already populated with 20-core 2.4 GHz CPUs.

With 512 GB of DDR4 installed across 16 modules, how many memory slots remain free for future upgrades?

The system has 24 DDR4 slots in total; 16 are occupied by 32 GB modules, leaving 8 slots available for expansion up to the 3 TB limit.
