Dell PowerEdge R660xs product overview
R660xs is not an AMD EPYC server and should not inherit the generic CPU language that was on the previous page. It is an Intel C741 / Xeon platform. The “xs” model is aimed at a more efficiency-focused configuration envelope than the full R660: fewer DIMM slots and a lower maximum memory ceiling, while retaining dual-socket 1U density and flexible storage for mainstream enterprise workloads.
Dell PowerEdge R660xs price, cost and quotation considerations
PowerEdge R660xs cost depends on processor pair, memory, drive/backplane choice, RAID/HBA, networking, PSU class and service. Because the platform is often considered as a value/density alternative to R660, quotes should be normalized to the same memory, storage, NIC and support level before comparing price.
Core features and capabilities
- 16 DDR5 DIMM slots with up to 1.5 TB RAM.
- Flexible 3.5-inch and 2.5-inch SAS/SATA/NVMe drive layouts.
- BOSS-N1 boot subsystem and PERC/HBA controller options.
- Two redundant AC or DC power supplies.
- iDRAC9, Redfish API and OpenManage tools.
- Enterprise OS support including Windows Server, Red Hat Enterprise Linux, SUSE, Ubuntu Server LTS and VMware vSAN/ESXi.

Performance and use-case information
R660xs is designed for workloads that value 1U density and balanced compute/storage rather than maximum memory capacity. The lower core-count limits and 16-DIMM architecture distinguish it from R660. For virtualization, organizations should size VM density against actual CPU model, memory capacity and storage IOPS instead of assuming every R660xs provides the same consolidation ratio.
Compatibility, software, connectivity and site requirements
Confirm CPU generation, memory population, front/rear drive backplane, RAID/HBA, NIC/OCP cards, PSU and rack depth. Dell’s manual warns against unsupported PCIe devices, so adapters should be selected from validated options. Operating system/hypervisor compatibility and iDRAC licensing should be matched to the production environment.
Applications
- Virtualization
- Cloud infrastructure
- Scale-out applications
- Enterprise web/application servers
- General database services
- Storage-heavy 1U nodes
- Branch or regional data-center workloads
Comparison with closely related models
R660xs versus R660 is primarily a scale and configurability comparison. R660 offers 32 DIMM slots, up to 8 TB RAM and higher-core-count 5th Gen Xeon support, while R660xs has 16 DIMM slots, up to 1.5 TB RAM and a more restrained CPU envelope. R660xs can therefore be a better cost/density fit where workloads do not need the R660’s maximum memory and expansion headroom.
What is included?
Confirm processor count, DIMM population, drive backplane, drives, PERC/HBA, NICs, PSUs, rails, bezel, power cords, iDRAC entitlement and Dell service. The exact service tag/BOM should match the written quotation.
Important limitations and buyer considerations
- Intel Xeon platform; AMD EPYC specifications do not apply.
- 16-DIMM / 1.5 TB ceiling is materially lower than R660.
- Chassis depth and weight vary by drive configuration.
- Power supply selection must match the ordered hardware and input voltage.
- Use only validated expansion devices if support coverage matters.
- Warranty is tied to the purchased Dell service/support configuration.
Who should buy this exact model?
The Dell PowerEdge R660xs is a good choice for buyers who want dual-socket 1U density with mainstream virtualization and storage flexibility but do not require the R660’s 8 TB memory ceiling or highest-core-count configurations.
Authoritative technical and manufacturer resources
For this PowerEdge server, verify the current Dell configuration matrix, validated expansion devices and purchased support entitlement.
