Dual-socket 1U rack server for dense compute

The PowerEdge R640 packs two Intel Xeon Gold 6148 processors, each running 20 cores at 2.4 GHz with a 3.7 GHz turbo frequency, into a single rack unit. Sixty-four gigabytes of DDR4 registered ECC memory across four 16 GB modules support virtualization clusters, database nodes, and high-performance workloads that demand core density and memory reliability. Redundant 750-watt platinum power supplies and included rails simplify deployment in standard cabinets.

PERC H730P controller with eight 1.2 TB SAS drives

A Dell PERC H730P 2 GB controller manages the eight 2.5-inch 10 K SAS drives, delivering 12 Gb/s throughput and hardware RAID levels 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode. The controller’s onboard battery protects cached writes during power loss, making the array suitable for transactional databases and mixed read-write workloads that require data integrity.

Sustained throughput under multi-core load

With all 40 cores active, the dual Xeon configuration maintains clock speeds near the base 2.4 GHz thanks to the 1U chassis airflow design and redundant cooling. The quad-port network daughter card provides two 1 GbE and two 10 Gb SFP+ links for continuous east-west traffic, while iDRAC 9 Enterprise enables remote monitoring and firmware updates without interrupting production services.

Klausimai apie šią prekę

How much memory bandwidth does the 2666 MHz DDR4 actually deliver in this 24-slot system?

The 24 DIMM slots run DDR4 at 2666 MHz, giving each channel its rated throughput; total bandwidth scales with how many of the 24 slots are populated.

What RAID levels can the PERC H730P 2 GB controller support on the 12 Gb/s SAS backplane?

The H730P handles RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through on the 12 Gb/s SAS backplane, limited by the eight 2.5-inch drive bays.

What rack depth do the included Ready Rails need for this 1U server?

The supplied Ready Rails mount the 1U chassis in standard four-post racks; the rail kit adjusts to common depths without extra brackets.
