Dual-socket 1U compute node

The PowerEdge R640 packs two Intel Xeon Gold 6148 processors, each running at 2.40 GHz with 20 cores, into a single rack unit. Sixteen 32 GB DDR4 modules deliver 512 GB of registered ECC memory at 2666 MHz. Eight 2.4 TB 10K SAS drives connect through a PERC H730P controller with 2 GB cache, supporting RAID 0, 1, 5, 6, 10, 50 and 60. Dual 750 W platinum power supplies and iDRAC 9 Enterprise complete the package.

Suited for dense virtualisation

This server targets workloads that demand high core counts and large memory capacity in minimal rack space. The quad-port network daughter card provides two 1 GbE and two 10 Gb SFP+ links for flexible fabric integration. Organisations requiring GPU acceleration or more than two sockets should evaluate alternative platforms. Buyers who need all-flash configurations or different drive bay counts will need another chassis.

512 GB DDR4 registered ECC memory

The installed 512 GB across 24 DIMM slots is the decisive figure for memory-bound applications such as in-memory databases or heavy virtualisation. Maximum supported capacity reaches 3 TB, so future expansion is possible within the same chassis. If the working set exceeds the current 512 GB, plan for additional modules before deployment.

Preguntas sobre este artículo

What does the 2.4 GHz base clock with 3.7 GHz turbo mean for sustained workloads on this server?

Each of the two Xeon Gold 6148 processors runs at 2.4 GHz base and can boost to 3.7 GHz, giving 40 cores total for compute-intensive tasks.

What RAID levels does the PERC H730P 2GB 12Gb/s controller support with the eight 2.4 TB SAS drives?

The H730P supports RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through, so the eight 2.4 TB 10K SAS drives can be arranged in any of those configurations.

How much DDR4 memory can be added beyond the 512 GB already installed?

The system has 24 DDR4 slots and 16 are populated with 32 GB modules, leaving 8 slots free to reach the 3 TB maximum.
