Dense 1U Dual-Socket Server

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out data centre computing. It ships with two Intel Xeon Silver 4116 processors, each running at 2.10 GHz with 12 cores. The system includes 64 GB of DDR4 registered ECC memory across four 16 GB modules and a PERC H730P storage controller with 2 GB cache.

Suited For Compute-Dense Virtualisation

This configuration fits virtualisation clusters, database nodes and high-performance computing workloads that benefit from dual-socket density in a single rack unit. The quad-port network daughter card provides two 1 GbE and two 10 Gb SFP+ connections. Buyers who need more internal drive bays than the eight 2.5-inch slots or who require GPU acceleration should look at larger platforms.

Eight-Bay 2.5-Inch Chassis Constraint

The 1U chassis supports exactly eight 2.5-inch SATA or SAS drives and ships with two 400 GB SATA SSDs installed. Expansion beyond these eight bays is not possible in this form factor. The H730P controller handles RAID 0, 1, 5, 6, 10, 50 and 60 for the installed and any additional drives.

Vragen over dit artikel

How do I decide between the two 400GB SSDs and adding more drives in the remaining bays?

The R640 has eight 2.5-inch bays; two are filled with 400GB SATA SSDs. The PERC H730P supports RAID 0/1/5/6/10/50/60, so you can add up to six more SATA or SAS drives and choose a RAID level that balances capacity and redundancy.

What does the 2.1GHz base clock with 3.0GHz turbo mean for sustained workloads?

Each Xeon Silver 4116 runs at 2.1GHz base and can boost to 3.0GHz when thermal headroom allows. With two 12-core CPUs you have 24 cores total, so multi-threaded applications see consistent throughput at base frequency and short bursts at the higher turbo speed.

What does the 12Gb/s SAS controller cap in practice?

The PERC H730P provides 12Gb/s SAS/SATA connectivity to the backplane. Real-world throughput is limited by the installed SATA SSDs at 6Gb/s and by the PCIe 3.0 x8 host link, so sequential reads top out around the drive’s SATA ceiling rather than the controller’s maximum.
