Description

The Dell PowerEdge R660 is a next-generation 1U rack server built for dense, high-performance data center environments that require extreme compute power in a compact footprint. Equipped with dual Intel Xeon Gold 6542Y processors (5th Gen, 24 cores each), the server provides 48 cores and 96 threads designed for AI workloads, virtualization clusters, cloud computing, and mission-critical enterprise applications.

Featuring 256GB of DDR5-5600 ECC memory, the R660 ensures fast bandwidth, lower latency, and enhanced error-correction capabilities. This makes it ideal for memory-intensive workloads such as in-memory databases, analytics engines, and HPC applications requiring sustained performance.

The server includes a powerful all-flash storage array built with 4 × 1.6TB SAS-4 24Gbps SSDs, providing ultra-high throughput and reliability for mixed-use enterprise environments. Storage is managed by the next-generation PERC H965i RAID controller with NV cache and 24Gbps SAS4 support, enabling exceptional I/O performance for high-density workloads.

For boot optimization, the BOSS-N1 module includes dual 480GB M.2 NVMe drives configured in RAID1, ensuring redundancy and rapid OS boot times. Networking capabilities are expanded with an Intel X710-T4L Quad-Port 10GbE BASE-T OCP 3.0 adapter, offering flexible and enterprise-grade connectivity.

With dual 1100W Titanium-rated power supplies, the R660 ensures efficient, reliable energy delivery with complete power redundancy. Managed through iDRAC9 Enterprise, administrators gain full remote access, lifecycle management tools, secure monitoring, and advanced automation controls.
