What does the HPE ProLiant line of servers mainly support?

The HPE ProLiant line of servers primarily supports the industry-standard x86 architecture. This architecture is widely recognized for its robustness, compatibility, and versatility, making it an ideal choice for a range of workloads and enterprise applications. ProLiant servers are designed to deliver high performance and keep pace with demands in both virtualization and traditional computing environments. Leveraging the x86 architecture allows these systems to seamlessly integrate with various operating systems and software applications which are commonly used in businesses today, ensuring that they can meet diverse customer needs efficiently.

When focusing on the other options, ARM architecture, while growing in popularity, is not the primary focus of the ProLiant line, as it is more commonly associated with mobile and consumer-grade devices rather than enterprise server solutions. Custom-built architectures may offer specialized processing capabilities but are not the standard for HPE's ProLiant offerings, which emphasize global compatibility and standardization. Cloud-based architectures, while increasingly important for modern IT, refer more to the services and deployment models rather than the physical architecture of the server hardware itself. Thus, the emphasis remains on the proven x86 architecture for HPE ProLiant servers.
