A server is a computer program or device that provides resources, data, services, or programs to other computers, known as clients, over a network. Types of server include web servers, file servers, network servers and database servers, although they are often referred to as dedicated servers because they carry out specific tasks for a specific purpose. In 2019, global server market revenues reached over 87 billion U.S. dollars, with 11.75 million servers shipped worldwide.
Coronavirus (COVID-19) impacts
However, analysts have predicted a decline in end user spending on servers in 2020, attributing this to the coronavirus (COVID-19) outbreak, with impacts including supply chain shortages as well as a change to demand from various groups of IT buyers. Businesses have been forced to consider more expedited adoption of cloud services, and as a result, the market saw a surge in demand for IT infrastructure, notably in cloud service provider datacenters. This has had an impact on the server market, resulting in a more moderate decline compared to other IT infrastructure segments.
Data centers and HPC
Data centers, centralized locations where computing and networking equipment is concentrated, can house multiple servers stacked in racks that are placed in rows. As a result, these are often described as server farms, consisting of thousands of computers which require a large amount of power to run and to keep cool. Where computer servers are used in this way to solve complex problems, it is often referred to as high performance computing (HPC). In 2020, HPC server revenues are forecast to amount to 14.5 billion U.S. dollars, with revenues generated by the HPC market as a whole set to amount to between 34 and 38 billion U.S. dollars.
Notable server vendors include Dell Technologies, Hewlett Packard Enterprise (HPE), Inspur, Lenovo, and IBM. In 2019, Dell’s server revenues amounted to over 15.5 billion U.S. dollars, whilst HPE generated close to 15 billion U.S. dollars in server revenue. Combined, these two vendors have accounted for between 30 and 40 percent of the server market worldwide. In addition to the manufacturers, the operating system of a server can also vary. In 2019, the Windows operating system was used on 72.1 percent of servers worldwide, whilst the Linux operating system accounted for 13.6 percent of servers. Similarly, there is also a choice in the type of processors used by servers, with the x86 variety most used in 2019.
