SmartOS is a free and open-source SVR4 hypervisor based on the UNIX operating system that combines OpenSolaris technology with bhyve and KVM virtualization.{{cite web | last=Frommel|first=Oliver|title= SmartOS Weds Open Solaris to Linux KVM Virtualization | url = http://www.admin-magazine.com/HPC/News/SmartOS-Weds-Open-Solaris-to-Linux-KVM-Virtualization | work = Admin magazine | accessdate = 31 December 2012}} Its core kernel contributes to the illumos project.{{Citation |title=illumos-gate |date=2023-06-16 |url=https://github.com/TritonDataCenter/illumos-joyent |access-date=2023-07-10 |publisher=Triton Data Center}} It features several technologies: Crossbow, DTrace, bhyve, KVM, ZFS, and Zones.{{Cite web |title=SmartOS {{!}} Triton DataCenter |url=https://www.tritondatacenter.com/tritondatacenter.com/smartos |access-date=2023-07-10 |website=www.tritondatacenter.com}}{{cite web | date = Aug 15, 2014 | url = http://www.datacenterknowledge.com/archives/2011/08/15/joyent-open-sources-smartos/ | title=Joyent Open Sources SmartOS for the Cloud | publisher=Data Center Knowledge | accessdate = January 1, 2013 | last = Miller | first = Colleen}} Unlike other illumos distributions, SmartOS employs NetBSD pkgsrc package management.{{cite web |title=MNX Packages Documentation - Home |url=https://pkgsrc.smartos.org/}}{{cite web |title=Joyent Packages Documentation - Home |url=https://pkgsrc.joyent.com/}} SmartOS is designed to be particularly suitable for building clouds and generating appliances.{{cite web | work = H online | url = http://www.h-online.com/open/news/item/SmartOS-brings-KVM-to-the-Solaris-kernel-1323425.html | title= SmartOS brings KVM to the Solaris kernel}} It was originally developed for and by Joyent, who announced in April 2022 that they had sold their business supporting and developing of Triton Datacenter and SmartOS to [https://www.mnxsolutions.com MNX Solutions].{{Cite web |date=April 11, 2022 |title=A New Chapter Begins for Triton and SmartOS |url=https://www.joyent.com/blog/a-new-chapter-begins-for-triton-and-smartos |access-date=2022-04-14 |website=Joyent}} It is open-source and free for anyone to use.

SmartOS is an in-memory operating system and boots directly into random-access memory. It supports various boot mechanisms such as booting from hard drive, USB thumbdrive, ISO Image, or over the network via PXE boot. One of the many benefits of employing this boot mechanism is that operating system upgrades are trivial, simply requiring a reboot from a newer SmartOS image version.{{cite web|last=Trent | first =Slater|title= SmartOS Fundamentals | date =27 February 2012| url = http://blog.smartcore.net.au/smartos-fundamentals/|publisher =SmartCore | accessdate = 27 February 2012}}

SmartOS follows a strict local node storage architecture. This means that virtual machines are stored locally on each node and do not boot over the network from a central SAN or NAS. This helps ensure that network latency issues are eliminated as well as to preserve node independence.
