ProLiant is a brand of server computers that was originally developed and marketed by Compaq and currently marketed by Hewlett Packard Enterprise. After Compaq merged with Hewlett-Packard (HP), HP retired its NetServer brand in favor of the ProLiant brand. HP ProLiant systems led the x86 server market in terms of units and revenue during first quarter of 2010. The HP ProLiant servers offer many advanced server features such as redundant power supplies, Out-of-band management with iLO or Lights-out 100, Hot-swap components and up to 8-Socket systems. Product lines Modular Line (ML) ML server models are tower-based. They aim towards maximum expandability. Density Line (DL) and RISC Line (RL) DL server models are rack-based. They aim towards a balance between density and computing power. Available models through product generations Scalable Line (SL) SL server models are rack-based. These models are mostly used in data centers and environments where a maximum of computing power is desired. Blade Line (BL) BL server models are enclosure-based. They are made specially for use in a blade enclosure and cannot be used without such. Blade systems aim towards maximum density and manageability at limited rack space. There are two models of blade enclosures: HPE BladeSystem c3000 Enclosure (8 Bays for Blades), and HPE BladeSystem c7000 Enclosures (16 Bays for Blades). One advantage of HP/HPE Blade Enclosures compared to competitors (such as IBM Blade Systems) has been that the older generation enclosures have been able to accommodate new generation BL servers just by upgrading the firmware for OA in the enclosure (Onboard Administrator). However improvements to back-plane of the enclosure in the new generation enclosures have enabled faster I/O capabilities (such as 10Gbit/s Ethernet adapters and switches, and Infiniband). The physical design of the enclosures has not changed since the first versions (other than the larger LCD screen at the front compared to the first generation enclosures, and new plastic covers and HPE branding on the 3rd generation enclosures). ProLiant MicroServer The HPE ProLiant MicroServer line of products are entry-level, low power, compact, and affordable servers meant for small business, home office, or edge computing. They offer user upgradable components and easy access to hard drives. There is the option to purchase the server with ClearOS installed in order for users to be able to enable applications via an easy-to-use web-GUI with minimal effort. Details ProLiant servers are separated into four main product lines - ML, DL,
