HPE ProLiant ML Servers (towers) are standalone units that contain all elements required to respond to requests by client computers. The advantages of a tower server is that it is relatively compact and it can be used in work areas which are not specifically designed to accommodate servers, meaning that you do not need a special data room or any special bays in which to install the server. Its simplicity and robustness also mean that the server is considered an ideal place to start for those looking to begin using a server in a small and midsize business. HPE's ProLiant ML Servers deliver simple, efficient business value and can help increase IT staff productivity and expedite service delivery.
HP ProLiant DL Servers(racks) are designed to be installed in a rack framework. This small and midsize business server is also known as a rack-mounted server. These servers require a rack to be installed, in which the servers can be placed and secured. Multiple servers can be stacked into one single rack, saving floor space and consolidating network resources. A rack server also simplifies cabling among network components.
HPE's ProLiant DL Servers are the most flexible, reliable, and performance-optimized rack servers-ever.
