Key Applications and Workloads


Virtualization

Consolidate virtual machines and enterprise workloads on a configurable server platform. Processor, memory, and storage resources can be selected to match virtualization density, application requirements, and infrastructure capacity.

In-Memory Databases

Support data-intensive database environments that benefit from large memory allocations and high compute capacity. Final configuration should be based on the database software's CPU, memory, storage, and licensing requirements.

Research Lab and National Lab Computing

Plan infrastructure for scientific research, technical computing, numerical analysis, and data-intensive experimentation. CPU, memory, accelerator, and networking selections should reflect the specific research workload.

Scale-Up High-Performance Computing (HPC)

Support compute-intensive workloads that require substantial processing resources within a single system. Evaluate parallel workload characteristics, memory bandwidth, storage throughput, and supported interconnect options when configuring the platform.

Customer Relationship Management (CRM)

Deploy server infrastructure for CRM databases, application services, reporting, and enterprise customer-management workloads. Capacity planning should account for concurrent users, database size, application architecture, and expected growth.

Enterprise Resource Planning (ERP)

Configure compute and memory resources for ERP application servers, business databases, reporting, and integrated enterprise services. Validate the final configuration against the requirements of the selected ERP software and deployment environment.
