Dense dual-socket 1U server

The PowerEdge R640 packs two Intel Xeon Silver 4110 processors into a single rack unit, each running at 2.1 GHz with eight cores and a 3.0 GHz turbo. With 128 GB of DDR4 ECC memory installed across eight 16 GB modules, it targets scale-out workloads that demand high compute density and remote manageability via iDRAC 9 Enterprise.

Storage and network limits

The PERC H730P controller supports RAID 0, 1, 5, 6, 10, 50 and 60 across SATA and SAS drives using a 12 Gb/s link. Two 400 GB SATA SSDs are installed in the eight 2.5-inch bays, while the X520/I350 daughter card provides two 1 GbE and two 10 Gb SFP+ ports for mixed-speed connectivity.

Upgrade path from single-socket or older 1U units

Replacing a single-processor 1U server doubles thread count and expands memory capacity toward the 3 TB ceiling across 24 DIMM slots. The jump is worthwhile when workloads outgrow a single socket's core count or when the 24-slot headroom lets you defer a new chassis purchase.

Vragen over dit artikel

Should I choose the 2 x 400 GB SSD configuration or add more drives to the 8 bays?

The system ships with two 400 GB SATA SSDs and six empty 2.5 inch bays; the PERC H730P supports RAID 0, 1, 5, 6, 10, 50 and 60 so you can expand with matching SATA or SAS drives later.

What does the 2.1 GHz Xeon Silver 4110 speed deliver in this 1U server?

Two 8‑core Xeon Silver 4110 processors run at 2.1 GHz base with 3.0 GHz turbo, giving 16 cores for dense virtualisation and scale‑out workloads in a 1U chassis.

How does the 12 Gb/s PERC H730P controller limit drive performance?

The H730P provides 12 Gb/s SAS and 6 Gb/s SATA connectivity; installed 400 GB SATA SSDs are capped at the SATA 6 Gb/s link speed, while future SAS drives can use the full 12 Gb/s bus.
