z/VM supports the z/Architecture [[HiperSockets]] function for high-speed [[TCP/IP]] communication among virtual machines and logical partitions (LPARs) within the same IBM zSeries server. This function uses an adaptation of the Queued-Direct Input/Output (QDIO) high-speed I/O protocol.

IBM later introduced LPARs to their [[IBM i|iSeries]] and [[IBM pSeries|pSeries]] servers in 1999 and 2001, respectively,<ref>{{cite web |url=http://www.ibm.com/developerworks/aix/library/au-aix-vioserver-v2/index.html |title=POWER5 Virtualization: How to set up the Virtual I/O Server |access-date=2008-09-25 |date=2005-06-29 |first=Nigel |last=Griffiths |url-status=dead |archive-url=https://web.archive.org/web/20080611131520/http://www.ibm.com/developerworks/aix/library/au-aix-vioserver-v2/index.html |archive-date=2008-06-11 }}</ref> albeit with varying technical specifications. Multiple operating systems are compatible with LPARs, including [[z/OS]], [[z/VM]], [[z/VSE]], [[z/TPF]], [[AIX operating system|AIX]], [[Linux]], and [[i5/OS|IBM i/OS]]. In [[disk array|storage systems]], such as the IBM TotalStorage DS8000, LPARs allow for multiple virtual instances of a storage array to exist within a single physical array.

In first part of 2010 year, [[Fujitsu]] announced availability of its [[x86 64]] PRIMEQUEST line of servers,<ref>[http://www.fujitsu.com/global/news/pr/archives/month/2010/20100331-01.html Fujitsu Upgrades Lineup of PRIMEQUEST Mission-Critical Servers]</ref> which support LPARs.
