Engineer's Note: The Intel Xeon Silver 4112 pairs 4 cores / 8 threads with a 2.60 GHz base clock that boosts to Not Supported on demand and 8.25 MB of on-die cache, making it a drop-in candidate for software-defined storage nodes and backup targets. Its FCLGA3647 socket means it slots into existing platforms without board redesign. Positioned as a cost-efficient tier aimed at dense, scale-out workloads, it is built for sustained multi-user workloads.
1. FCLGA3647 platform compatibility: matching sockets across your fleet simplifies spares management — one processor SKU covers many chassis generations, and upgrades become a socket swap rather than a board replacement. That matters at 3 a.m. when a node needs to be back in service before morning.
2. Memory platform on the Intel Xeon Silver 4112: support for DDR4-2400, up to 768 GB of RAM, 115.2 GB/s of peak bandwidth. This is the headroom in-memory databases and dense VM farms need — capacity for growth, bandwidth for the data streams in between.
3. 4 cores / 8 threads: hardware multi-threading lets each physical core run two instruction streams, so concurrent workloads — software-defined storage nodes and backup targets — share the die without context-switch overhead. When you size licenses or plan VM placement, thread count is the number the scheduler actually sees.
4. Scalability to 2-socket systems: in multi-socket servers the processors share memory over a coherent interconnect, letting a single OS instance use all cores and all RAM — the classic architecture for large relational databases and consolidation hosts.
5. 8.25 MB of shared cache: a large last-level cache keeps hot working sets on-die, cutting memory round-trips for databases and compilers. Fewer main-memory accesses translate directly into lower average latency and better tail performance under load — often the difference you feel before any benchmark confirms it.
If your roadmap includes software-defined storage nodes and backup targets, the Intel Xeon Silver 4112 turns architectural decisions into predictable outcomes. Its 4-core layout sizes the node for expected concurrency, the Not Supported turbo headroom keeps interactive paths responsive, and 768 GB of addressable memory gives the platform room to grow. Every unit passes functional testing before shipment, and our bulk-pricing desk keeps multi-socket refresh projects inside budget.
Q: Does this CPU include a cooler?
A: Server processors are typically installed with chassis-specific heat sinks, so none is included. Match the heat sink to your server model for correct airflow direction — our team can advise on the right part.
Q: Is it new or refurbished? What warranty applies?
A: We offer both new and tested refurbished units — the condition is shown on each listing. All processors include a one-year warranty and pass functional testing (boot, memory controller, all cores) before dispatch.
Q: What workloads suit 4-core processors best?
A: With 4 cores / 8 threads, this processor is sized for multi-threaded server workloads: virtualization hosts, database servers, and application consolidation. Single-threaded-light environments (file servers, internal tools) will leave headroom unused.
Q: Can I mix this processor with different models in the same server?
A: In multi-socket servers, matched processors (same model, same stepping) are strongly recommended. Mixed models can cause boot failures or instability because memory controllers and QPI/UPI links negotiate to the lowest common configuration.
Q: Do you offer bulk pricing for fleet upgrades?
A: Yes. Multi-socket refresh projects and fleet orders get consolidated pricing — request a quote through the form on this page with your target quantity, and our team responds with an offer typically within one business day.
