Let's start with the basics: HPE stands for Hewlett Packard Enterprise. Founded on November 1, 2015, in Palo Alto, California, HPE emerged following the division of the original Hewlett-Packard company. While HP Inc. zeroes in on PCs and printers, HPE is all about business IT solutions, encompassing servers, storage, networking, and consulting. Many individuals, particularly long-time IT professionals (including some of our colleagues), still say HP - there are servers still in operation from the period before HPE times.


The Meaning of the First Letter in HPE ProLiant Server Names


The first letter indicates the type of the HPE ProLiant server:


  • ProLiant DL (Density Line) - DL server models are rack-based. They are a good mix of size and computing power.

  • ProLiant ML (Maximum Expansion) - ML server models are tower-based. They are designed for optimal expandability.

  • ProLiant BL (Blades) - BL server models are enclosure-based. They are made specially for use in a blade enclosure and cannot be used without such (C7000 and C3000). Blade systems are designed for high density and easy management within tight rack spaces. More information on this can be found: Latest Blade Servers.

  • ProLiant SL (Scalable Line) - SL server models are rack-based. They're used when a lot of computing power is needed, such as in big data centers.

  • HPE ProLiant MicroServer: These are small servers. You can lay them flat or stand them up, depending on your available space. They're great for small businesses or home offices.


The Number Naming System of HPE ProLiant Servers


  • The first number after the initial letter signifies the system's class. Numbers 1, 3, 5 indicate the HPE series, higher number means higher performance.

  • The second number - 0,6, 8 marks the ranking within the series, higher number means more features.

  • The third number identifies the CPU manufacturer: 0 for Intel and 5 for AMD.

 

For example, the DL380 model is a rack-mountable, midle ranked server, equipped with Intel processors.
