The new Dell PowerEdge R660 is a 1U, two-socket rack server. Gain the performance you need with this full-featured enterprise server, designed to optimize even the most demanding workloads like dense database analytics and high-density virtualization.
- Add up to two Next Generation Intel® Xeon® Scalable processors with up to 56 cores for faster and more accurate processing performance.
- Accelerate in-memory workloads with up to 32 DDR5 RDIMMS up to 4400 MT/sec (2DPC) or 4800 MT/sec for 1DPC (16 DDR5 RDIMMs max).
- Support for GPUs including 2* x single-wide for workloads requiring acceleration.
- New Smart Flow chassis optimizes airflow to support the highest core count CPUs in an air-cooled environment within the current IT infrastructure.
- Support for up to 8 x 2.5” drives and 2 x 350 watt processors.
Security is integrated into every phase of the PowerEdge lifecycle, including protected supply chain and factory-to-site integrity assurance. Silicon-based root of trust anchors end-to-end boot resilience while Multi-Factor Authentication (MFA) and role-based access controls ensure trusted operations.
- Achieve maximum efficiency with multiple chassis designs that are tailored to your desired workloads and business objectives.
- Storage options include up to 8 x 2.5” NVMe/SAS4/SATA, plus up to 10 x 2.5” NVMe/SAS4/SATA, 14/16 x NVME E3.S Gen5*.
- Multiple Gen4 and Gen5 riser configurations (up to 3 x PCIe slots) with interchangeable components that seamlessly integrate to address customer needs over time.
The Dell R660 is a 1U 2 Socket 32 DIMM server with 3 PCIe slots, 1 OCP, and 1 LOM. This server has 3 chassis options and supports SAS/SATA/NVMe and EDSFF drives. Below you will see more details about each chassis storage option and the drives supported.
