Lenovo ThinkSystem SR655 V3 Single-socket AMD EPYC Rack Server with 160 Cores and PCIe 5.0 I/O

The Lenovo ThinkSystem SR655 V3 is a high-performance single-socket 2U enterprise rack server built around 4th & 5th Gen AMD EPYC processors (Genoa / Turin architecture). Delivering industry-leading single-socket compute density, massive storage scalability, full PCIe 5.0 I/O support and flexible GPU expansion, it is the ideal workhorse for dense virtualization, VDI desktop cloud, enterprise OLTP databases, software-defined storage (SDS), big data analytics, edge AI inference and cloud-native workloads. With robust RAS reliability, energy-efficient Platinum/Titanium hot-swap power supplies and Lenovo XClarity unified remote management, the SR655 V3 balances extreme multi-thread throughput, expandable storage and low total cost of ownership for mid-to-large enterprises, telecom and data center deployments.

1. Industry-Leading Single-Socket AMD EPYC Compute Performance

   Powered by cutting-edge 5th Gen AMD EPYC 9005 Turin processors with up to 160 cores and 320 threads, the SR655 V3 achieves record-breaking SPEC CPU benchmark scores for single-socket servers. Massive core and thread density dramatically reduces server quantity for virtual machine clusters, database and batch analytics workloads, cutting hardware procurement and rack space costs compared to multi-socket alternatives.

2. Massive TruDDR5 Memory Bandwidth & Capacity

   12-channel TruDDR5 ECC memory running up to 6400MT/s delivers exceptional memory throughput for memory-hungry VDI, in-memory databases and cache services. ECC hardware correction eliminates unplanned downtime caused by transient memory faults, while up to 1.5TB total memory capacity supports hundreds of concurrent virtual machines on a single 2U chassis.

3. Ultra-High-Density Flexible Storage Architecture

   The SR655 V3 offers unmatched storage flexibility with mixed 2.5” NVMe high-speed flash and 3.5” large-capacity HDD layouts. Up to 40 front/mid/rear hot-swap drive bays enable multi-PB local storage deployment for software-defined storage, video surveillance and backup archive workloads. Hot-plug drive design allows capacity expansion without full server power-off, simplifying daily IT maintenance.

4. PCIe 5.0 I/O & Versatile GPU Acceleration

   Native PCIe 5.0 lanes deliver double the bandwidth of PCIe 4.0 for NVMe SSD arrays and high-speed 100GbE networking. Multiple full-height GPU slots support low-profile and double-width accelerator cards, making the server a cost-effective single-node platform for computer vision AI inference, generative AI lightweight model serving and graphics-intensive VDI workloads.

5. High-Efficiency Power & Advanced Energy Saving

   Optional 80 PLUS Titanium redundant power supplies minimize idle power draw and cooling load, lowering monthly data center electricity expenses. Optimized hexagonal airflow chassis design improves heat dissipation; low-voltage DDR5 memory cuts memory power consumption by roughly 20% vs legacy DDR4 platforms, supporting sustainable green data center operation.

6. Intelligent Unified XClarity Remote Management

   Lenovo XCC built-in management chip enables full out-of-band server control without a local operating system, covering hardware health monitoring, remote KVM, one-click firmware flashing and fault alerting. XClarity Administrator centralizes deployment and maintenance for hundreds of ThinkSystem servers, drastically reducing manual IT operation labor for multi-site enterprises.
