Description
The HPE P18447-B21 is a high-performance 128GB Load-Reduced Dual In-line Memory Module (LRDIMM) designed for enterprise servers. It operates at a speed of DDR4-2666MHz, providing substantial bandwidth for memory-intensive applications. The LRDIMM form factor is crucial for systems requiring higher memory capacities, as it reduces the electrical load on the memory controller, allowing for more modules to be populated. This memory module features an 8Rx4 configuration, indicating eight ranks of memory chips, each with four data bits. This multi-rank design can improve performance by allowing the memory controller to access different ranks concurrently. The CAS Latency (CL) is 19, which specifies the delay between the memory controller requesting data and the data being available. It also incorporates ECC (Error-Correcting Code) functionality, which detects and corrects single-bit errors, enhancing system stability and data integrity. Specifically designed for HPE ProLiant servers, this 128GB DDR4 LRDIMM is ideal for demanding workloads such as large databases, virtualization, in-memory analytics, and high-performance computing. Its substantial capacity and advanced features contribute to improved application performance and overall system reliability in critical enterprise environments.
