ProLiant

ProLiant is a line of server computers produced by Hewlett-Packard Enterprise (HPE), originally introduced by Compaq in the 1990s and subsequently carried forward by HP after its 2002 acquisition of Compaq. The ProLiant family covers rack-mount, blade, and tower servers intended for enterprise data centers and cloud deployments.

Models in the ProLiant family are categorized into series such as DL (dense rack-mount servers), ML (tower servers), and BL (blade servers). Over successive generations, processors have shifted from Intel Xeon and AMD Opteron to modern Intel Xeon Scalable and AMD EPYC, with increasing memory capacity and PCIe expansion. Most units include hot-swappable drive bays, redundant power, and integrated remote management.

Management and software: ProLiant servers include HP's Integrated Lights-Out (iLO) management interface for remote administration, and can be deployed with management tools such as HP Insight Control and HP SmartArray storage controllers. They run a range of operating systems, including Windows Server and major Linux distributions, and support virtualization platforms such as VMware ESXi, Microsoft Hyper-V, and KVM.

Impact: ProLiant has been a common choice for business servers, hosting enterprise applications, database workloads, virtualization infrastructures, and HPC nodes. The brand remains part of Hewlett Packard Enterprise's portfolio, following the 2015 separation of HP into HPE and HP Inc.
