540-6223-01 Sun Fire E4900 CPU/Memory Uniboard
Sun Microsystems 4-slot UltraSPARC IV/IV+ CPU and 32-slot memory expander Uniboard assembly for Sun Fire E4900 enterprise servers.
The 540-6223-01 is an internal multi-node computational processing system engineered to deliver cost-effective performance and enhanced system stability within enterprise virtualization frameworks. Functioning as a high-density Uniboard processor and memory expander board, this essential architecture layer integrates directly into the server's centerplane to deliver scalability for up to four UltraSPARC IV or IV+ processors and 32 registered ECC DIMM memory modules. This structured layout expands internal data processing pipelines across high-density databases, continuous multi-threaded enterprise workloads, and legacy hardware consolidations. Its fault-isolated logic routing manages inter-bus communication securely, shielding vital compute corridors from logical failures, data disruptions, and unexpected thermal exceptions during continuous runtime operations.
