Lenovo ThinkSystem SR680a V4 4U Rack Server with 4-Socket 5th Gen Intel Xeon, 12TB TruDDR5 Memory, and PCIe Gen5 Multi-GPU Acceleration

The Lenovo ThinkSystem SR680a V4 is a top-tier 4U four-socket accelerated rack server engineered for mixed mission-critical workloads, including ultra-large OLTP databases, in-memory computing, financial risk simulation, multi-GPU LLM inference, high-end 3D visualization and carrier-grade virtualization. Powered by four 5th Gen Intel Xeon Scalable Emerald Rapids processors, this flagship platform integrates massive TruDDR5 memory capacity, full PCIe 5.0 expansion for multi-GPU accelerators, high-density U.3 NVMe flash storage, dual-zone precision cooling and N+2 redundant titanium power supplies. Supported by complete enterprise RAS reliability architecture, ThinkShield end-to-end security suite and Lenovo XClarity out-of-band intelligent management, the SR680a V4 delivers 99.999% uptime to meet the non-stop operation demands of banking, capital markets, government, telecommunications and large manufacturing enterprises. It consolidates transaction computing, big data analytics and AI acceleration into a single chassis to reduce data center rack space and overall IT total cost of ownership.

Four 5th Gen Intel Xeon Scalable processors deliver up to 256 total CPU cores to eliminate performance bottlenecks for ultra-large databases and multi-tenant virtualization clusters. High-speed UPI interconnects maintain ultra-low cross-processor latency, perfectly matching microsecond-level response requirements of financial core transaction systems. High TDP CPU support ensures sustained full-load operation 24/7 without thermal throttling.

48 memory slots expand to a maximum of 12TB DDR5 high-capacity memory with multi-layer hardware fault protection including mirroring and sparing. Users can load complete enterprise datasets and large AI model weights entirely into memory, drastically reducing persistent storage I/O delays. Hardware ECC automatically corrects memory bit errors to avoid unexpected production service downtime.

Up to 24 front U.3 hot-swap NVMe bays provide microsecond-level flash latency for database transaction logs, real-time business read-write requests and AI model caching. Universal AnyBay trays support flexible mixed deployment of high-performance NVMe flash and high-capacity HDDs to balance performance and storage cost. Hot-swap design allows online storage expansion without shutting down core production services.

Massive PCIe 5.0 expansion bandwidth supports high-speed storage adapters, 100GbE cluster network cards and up to eight double-width data center GPUs. The SR680a V4 integrates database processing, big data analytics and AI acceleration within a single 4U chassis, removing the need for separate independent GPU nodes and cutting data center rack occupation and hardware investment costs.

High-wattage Titanium power supplies support N+2 full redundant configuration to eliminate power failure risks for zero-downtime core business systems. Independent front and rear dual cooling zones with hot-swappable redundant fans provide targeted heat dissipation for CPUs, memory banks and high-power GPUs, avoiding performance reduction under long-duration heavy loads while optimizing data center cooling energy consumption.

A full set of Reliability, Availability, Serviceability (RAS) features covers all key hardware subsystems: hot-swappable drives, fans and power supplies, memory fault isolation, predictive hardware failure analysis, automatic component fault segmentation and live component replacement. These features achieve carrier-grade 99.999% annual uptime to satisfy strict non-stop operation standards of financial, government and telecom core infrastructure.

The independent XCC out-of-band management chip monitors all hardware metrics 24/7 and pushes real-time fault notifications before service impact occurs. XClarity Administrator automates mass server deployment, firmware maintenance and resource scheduling for hundreds of accelerated mission-critical nodes, greatly reducing manual operation workload for enterprise IT teams managing mixed database-AI workload environments.
