Dense 1U dual-socket server for scale-out workloads

The Dell PowerEdge R640 fits two Intel Xeon Gold 5118 processors in a single rack unit. Each CPU runs at 2.3 GHz with 12 cores and a 3.2 GHz turbo frequency. The system ships with 256 GB of DDR4 2400 MHz registered ECC memory across eight 32 GB modules. It is built for data-centre deployments that need high compute density.

SAS interface limits drive choices to spinning media

The PERC H730P controller provides 12 Gb/s SAS and SATA connectivity with RAID levels 0, 1, 5, 6, 10, 50 and 60. Only two 300 GB 10K SAS drives are installed in the eight 2.5-inch bays. No solid-state drives are present, so capacity and IOPS are constrained by mechanical disks unless additional SAS or SATA SSDs are sourced separately.

256 GB DDR4 across 24 slots defines upgrade path

Memory is the single specification that decides fit: 256 GB is populated in eight of twenty-four slots, leaving room to reach the 3 TB maximum. All modules must be DDR4 registered ECC; other generations or unbuffered types will not work. Buyers who need more memory headroom should verify slot availability before purchase.

Klausimai apie šią prekę

Should I pick the 256 GB configuration or add more DDR4 modules up to the 3 TB maximum?

The system ships with 256 GB across eight 32 GB DDR4 2400 MHz registered ECC modules; 24 slots exist, so you can expand later if workloads demand more capacity.

What does the 2.3 GHz base clock with 3.2 GHz turbo mean for actual throughput on the two Xeon Gold 5118 CPUs?

Each processor has 12 cores at 2.3 GHz base and can boost to 3.2 GHz under load, giving 24 total cores for parallel workloads such as virtualization or database tasks.

How does the 12 Gb/s SAS controller and 10 Gb SFP+ network card limit real-world storage and network speeds?

The PERC H730P controller runs at 12 Gb/s SAS/SATA with RAID 0/1/5/6/10/50/60, while the X520/I350 card provides two 10 Gb SFP+ and two 1 GbE ports for network throughput.
