Virtualization for aggregation
open-in-new
<p>Virtualization for aggregation combines <a href="/facts/Server_(computing)/dEaYFD7r">physical servers</a> and their memory and CPU power to create a single, large <a href="/facts/Virtual_machine/BLevU3sx">virtual machine</a>. </p><p>Virtualization for aggregation is the opposite of traditional <a href="/facts/Server_virtualization/k2guIbBX">server virtualization</a>, which partitions a single physical system so that multiple <a href="/facts/Operating_system/8XTuvMh2">OSes</a> can be run on the hardware. The technology is primarily used to run compute-intensive applications on a virtual <a href="/facts/Symmetric_multiprocessing/T9CahUsN">symmetric multiprocessing</a> (SMP) system, and can benefit users who want to provide very large memory and capacity resources for <a href="/facts/High-performance_computing/HT9NwGAN">high-performance computing</a> (HPC) needs without having to invest in proprietary SMP systems, which are beyond the reach of many users. </p>
