Dell PowerEdge R660xs – Mid-Range Rack Server 2x Xeon Silver

Dell PowerEdge R660xs Rack Server – Mid-Range Rack Server with Dual Xeon Silver

The Dell PowerEdge R660xs Rack Server (Mid-Range Rack Server) is a high-performance, dual-CPU mid‑range rack server designed for virtualized environments, databases, application servers, and high‑density business workloads. Featuring a 2.5″ chassis with support for up to 10 SAS/SATA hard drives and two Intel Xeon Silver 4510 processors, it offers strong compute density and flexible storage options in a compact rack footprint.

Each Intel Xeon Silver 4510 CPU runs at 2.4GHz, with 12 cores / 24 threads, 30MB cache, Turbo and Hyper‑Threading. With 2 CPUs, the system provides a total of 24 cores / 48 threads, ideal for multi‑VM and parallel workloads. It comes with 64GB DDR5 5600MT/s RDIMM (dual rank), offering high bandwidth and room for future expansion. A 480GB SATA Mix‑Use SSD (2.5″ hot‑plug) is included for fast OS and application storage.

The PERC H755 SAS front RAID controller (RAID 0/1/5) handles storage resilience and performance, while networking is provided by Broadcom 5720 dual‑port 1GbE on‑board LOM plus a Broadcom 57416 dual‑port 10GbE BASE‑T OCP NIC 3.0. Enterprise-grade remote management is enabled by iDRAC Enterprise 16G / iDRAC9 Enterprise 15G, and power reliability is ensured with dual, redundant (1+1) hot‑plug 1100W Titanium power supplies (100–240Vac). The server ships with rack rails, standard bezel, and 3 Year Basic Next Business Day Onsite support.

Detailed Specification Table

Key Value Highlights for Your Business

• Dual CPU Compute Density: By packing 24 physical cores into a 1U frame, this server is an ideal “virtualization host.” It allows you to run double the number of Virtual Machines compared to a single-processor server within the same rack space.
• Mixed Use (MU) SSD: The included 480GB drive is a “Mixed Use” SSD, which offers higher endurance (higher DWPD) than standard “Read Intensive” drives. This makes it much more reliable for hosting operating systems or write-heavy applications.
• Dual Rank DDR5: The 64GB DDR5 memory is Dual Rank, which typically provides slightly better performance for memory-intensive applications by allowing the processor to access memory more efficiently.
• 10GbE High-Speed Backbone: The Broadcom 57416 10GbE adapter ensures that the server isn’t throttled by network congestion, allowing for rapid data transfer between the server and your core network switches.
• Titanium Power Efficiency: The 1100W Titanium redundant power supplies are the highest efficiency tier available, minimizing heat production—a critical factor when stacking multiple 1U servers in a single cabinet.
