Comparing the Dell PowerEdge R660 with R760 in key aspects

1. Form Factor and Dimensions

• R660: This is a 1U rack server, meaning it's designed to fit compactly in a data center rack, taking up less vertical space.  
• R760: This is a 2U rack server, indicating it's taller and can generally accommodate more expansion and features.  

Comparison: The R660 is for environments where space is a premium, while the R760 prioritizes expandability.

2. Processors

• R660: Supports up to two Next Generation Intel® Xeon® Scalable processors, with up to 56 cores.  
• R760: Supports up to two 4th Gen Intel® Xeon® Scalable Processors, also with up to 56 cores.  

Comparison: Both use high-performance Intel Xeon Scalable processors, but the R760 specifically uses 4th generation processors.  

3. Memory

• R660: Up to 32 DDR5 RDIMMs.  
• R760: 32 DDR5 DIMM slots.  

Comparison: Both use DDR5 memory, the latest generation, but check the exact speeds and capacities supported as they might vary slightly.  

4. Storage

• R660: Offers various storage options, including 2.5" NVMe/SAS4/SATA drives.  
• R760: Supports both 3.5" and 2.5" drives with SAS, SATA, and NVMe options.  

Comparison: The R760 generally provides more storage flexibility due to its 2U form factor, supporting a wider range of drive sizes and configurations.  

5. Expansion Slots

• R660: Multiple Gen4 and Gen5 PCIe slots.  
• R760: PCIe 5.0 enabled expansion slots.  

Comparison: Both support the latest PCIe Gen5 for high-speed I/O, but the R760 emphasizes this feature.  

6. Cooling

• R660: Air-cooled with a Smart Flow chassis for optimized airflow.  
• R760: Primarily air-cooled but offers optional Direct Liquid Cooling (DLC) for certain configurations.  

Comparison: The R760 has an option for liquid cooling, which can be beneficial for high-density, high-performance environments.  

7. Management

• Both servers include the Dell OpenManage systems management portfolio for efficient server management. 

 

In Summary

-Choose the R660 if you need a powerful server in a space-saving 1U form factor.  

-Choose the R760 if you need maximum expandability, storage flexibility, and the option for liquid cooling in a 2U form factor.
