This is a DSP (Delivery Service Partner / OEM) license for Windows Server 2025 Datacenter edition, 64-bit, licensed for 24 cores. Datacenter edition is Microsoft's top-tier Windows Server SKU, distinguished from Standard mainly by unlimited Windows Server virtual machine rights on the licensed host (Standard is capped at two), making it the edition of choice for heavily virtualized hosts and private cloud/hyper-converged deployments. A DSP license is tied to the hardware it's first installed on, similar to other OEM software licensing, and is typically purchased alongside new server hardware rather than as a standalone volume license. Core-based licensing means the 24-core figure must cover the physical cores in the target server.
