## Long description

The Hewlett Packard Enterprise DL380 Gen9 ES-2697Av4 processor is a server-class CPU designed for use in HP Enterprise ProLiant DL380 Gen9 systems that accept the LGA 3647 socket. Operating at a base frequency of 2.6 GHz and offering 18 physical cores with 45 MB of shared cache, this processor is intended to deliver reliable multi-threaded performance and effective memory handling in data centre and enterprise server workloads. It is identified by the manufacturer part number 817955-B21-RFB and is suitable for environments that require consistent compute resources and compatibility with Gen9 platform features.
Advantages
The ES-2697Av4 provides a balance of core count and frequency for parallel processing tasks, with 18 cores that support higher concurrency for virtualization, database, and compute-dense applications. The 45 MB cache helps reduce memory latency for frequently accessed data, and the LGA 3647 socket ensures compatibility with Gen9 motherboard designs that support enterprise features such as advanced memory configurations and server management. The processor’s design focuses on stability and predictable performance in continuous server operation.
Suitable for
 Virtualization hosts and hypervisor nodes
 Database servers with moderate to high transaction loads
 Compute clusters for parallel workloads and batch processing
 File, application, and web servers in enterprise datacentres
