DELL PowerEdge R650xs 1U rack server 2x Xeon Silver 4310 2.1GHz 12-core 128GB DDR4 10x 1.8TB SAS H745 2x 1400W

Dense 1U compute node

The Dell PowerEdge R650xs is a 1U rack server built for data-centre workloads that demand high core density in minimal space. It ships with two Intel Xeon Silver 4310 processors, each running at 2.1 GHz with 12 cores, and 128 GB of DDR4 registered ECC memory across eight modules. The platform supports up to two processors and 1 TB of total memory, making it suitable for virtualisation, cloud infrastructure and dense analytics.

Front-access storage and redundant power

Ten 2.5-inch drive bays sit at the front, populated with 1.8 TB 10 K SAS drives connected to a PERC H745 RAID controller with 4 GB NV cache and battery backup. The controller supports RAID 0, 1, 5, 6, 10, 50 and 60 for flexible data protection. Dual 1400 W platinum hot-swap power supplies provide redundancy, while a Broadcom 57412 dual-port 10 GbE SFP+ OCP 3.0 card handles high-speed networking. iDRAC 9 Enterprise enables full remote management, and ready rails with a front bezel are included for quick rack installation.

Upgrade from older 1U or tower systems

Organisations replacing earlier-generation 1U servers or tower workstations gain significantly higher core counts, faster memory speeds up to 3200 MT/s and modern SAS connectivity in the same rack footprint. The jump is worth it when workloads require more concurrent threads, larger memory capacity or hardware RAID with battery-backed cache. Buyers who need GPU acceleration, NVMe-only storage or single-thread frequencies above 3.3 GHz turbo should evaluate alternative configurations.
