It was first published by [[Novell]] in March 2005 to succeed their [[NetWare]] product.<ref name="Morgan">{{cite web |url=https://www.theregister.co.uk/2011/12/13/novell_open_enterprise_server_11/ |last=Prickett Morgan |first=Timothy |date=13 December 2011 |title=NetWare-Linux Love Child Turned Up to 11 |website=[[The Register]] |access-date=2017-02-07}}</ref>

Unlike NetWare, OES is a [[Linux distribution]]—specifically, one based on [[SUSE Linux Enterprise Server]].<ref>{{Cite web |last=Rouse |first=Margaret |date=December 21, 2011 |title=Open Enterprise Server |url=https://www.techopedia.com/definition/26069/open-enterprise-server-oes |url-status=live |archive-url=https://web.archive.org/web/20230810085220/https://www.techopedia.com/definition/26069/open-enterprise-server-oes |archive-date=August 10, 2023 |access-date=October 31, 2023 |website=Techopedia}}</ref> The first major release of Open Enterprise Server (OES 1) could run either with a [[Linux kernel]] (with a [[NetWare]] [[compatibility layer]]) or Novell's [[NetWare]] [[Kernel (operating system)|kernel]] (with a [[Linux]] compatibility layer).<ref name="Morgan" /> Novell discontinued the NetWare kernel prior to the release of OES 2, but NetWare 6.5 SP7, and later SP8, can run as a [[Paravirtualization|paravirtualized]] [[Hardware virtualization#Paravirtualization|guest]] inside the [[Xen]] [[hypervisor]] (officially supported until 7 March 2012, Novell self-supported until 7 March 2015).

=={{anchor|1.01|2.03}}OES 1 and OES 2 ==
Novell released OES 1, the first version of OES, on 25 March 2005.<ref name="Morgan" /> Since some users wanted [[backward compatibility]] with NetWare, Novell offered two installation options: OES-NetWare and OES-Linux. These are two different operating systems with different kernels and different [[User space#Overview|userlands]].

OES-NetWare is NetWare v6.5 equipped with [[NetWare Loadable Module]]s for various Novell services (such as [[NetWare Core Protocol]], [[Novell eDirectory]], [[Novell Storage Services]], and [[iPrint]]) and [[open-source software]] (such as [[OpenSSH]], [[Apache Tomcat]], and the [[Apache HTTP Server]]).<ref>{{Cite web |last=Hewlett Packard Enterprise |date=October 21, 2005 |title=Open Enterprise Server (OES) |url=https://www.hpe.com/psnow/doc/c04283233 |url-status=live |archive-url=https://web.archive.org/web/20220717064800/https://www.hpe.com/psnow/doc/c04283233.html |archive-date=July 17, 2022 |access-date=October 31, 2023 |website=Hewlett Packard Enterprise |type=Imbedded PDF |format=PDF}}</ref>

OES-Linux is based on the [[SUSE Linux Enterprise Server]] (SLES) with added NetWare services ported to the Linux kernel: e.g. the NetWare Core Protocol, Novell eDirectory, Novell Storage Services, and iPrint.

Novell released OES 2, the second version of OES, on 12 October 2007. It was the first SLES-Linux-kernel-only OES, but it retained the OES-NetWare operating system option, as NetWare 6.5 SP7 can run as a [[Paravirtualization|paravirtualized]] [[Hardware virtualization#Paravirtualization|guest]] inside the [[Xen]] [[hypervisor]]. The SLES base of the OES 2 was later updated to SLES 10 SP1.

Features introduced in OES 2 include:<ref>{{cite web |url=http://www.novell.com/documentation/oes2/upgrade_to_oes_lx/?page=/documentation/oes2/upgrade_to_oes_lx/data/front.html |title=Upgrading to OES2: Planning & Implementation Guide}}</ref>

* Dynamic Storage Technology, which provides Novell Shadow Volumes
* [[Windows domain]] services (from OES 2 SP1)
* [[Apple Filing Protocol]] (AFP) with Cross Protocoll Locking AFP-NCP-Samba (CPL) (from OES 2 SP1)

== OES 2015==
* OES 2015 was released on 31 August 2015, adding new features and improved performance.<ref name=v2015>{{cite web |url=https://www.novell.com/products/openenterpriseserver/ |title=Manage File & Print Networks - Open Enterprise Server |newspaper=Novell Web site |access-date= 20 November 2015}}</ref>
* OES 2015 SP1 was released on 14 June 2016 and was the first to be rebranded [[Micro Focus]]<ref name=v2015.1>{{cite web |url=https://www.novell.com/documentation/oes2015/pdfdoc/oes_readme/oes_readme.pdf|title=OES 2015 Readme |access-date= 16 December 2023}}</ref> after Micro Focus purchased [[The Attachmate Group]] which included Novell.

== OES 2018 & 2023 ==
Micro Focus released OES 2018 in November 2017, with three service releases (the last being OES 2018 SP3 in July 2021). All releases were all based on SLES 12 and its service packs.

While SUSE was sold by Micro Focus in 2018,<ref>{{Cite magazine |last=Burton |first=Graham |date=2 July 2018 |title=Micro Focus to sell SUSE Linux to private equity firm for US$2.5bn |url=https://www.computing.co.uk/ctg/news/3035155/micro-focus-to-sell-suse-linux-to-private-equity-firm-for-usd25bn |magazine=[[Computing (magazine)|Computing]] |access-date=29 August 2018}}</ref> SLES support and updates are included with an OES installation, provided at least one OES component is installed.

OES 2023 was released in October 2022, using a base of SLES 15 SP4. It includes a new Unified Management Console (UMC) to supersede iManager for server management, TLS 1.3 support and was bundled with NetIQ eDirectory 9.2.7.<ref name=v2023>{{cite web |url=https://www.microfocus.com/documentation/open-enterprise-server/2023/unified_management_console/overview.html|title=What's New or Changed in OES 2023 |access-date= 16 December 2023}}</ref>
Breaking with previous convention, OES 23.4 (rather than SP1) was released in October 2023, and was rebranded to [[OpenText]],<ref name=v23.4>{{cite web |url=https://www.microfocus.com/documentation/open-enterprise-server/23.4/oes_readme/t4f3jxli8w2p.html#t4me07gaejta|title=What's New or Changed in OES 23.4 |access-date= 16 December 2023}}</ref> after their purchase of Micro Focus earlier in the year. General support was extended to 3 years from the usual 2 years of previous releases.<ref name=sles_entitlement>{{cite web |url=https://support.microfocus.com/kb/doc.php?id=7023123|title=SLES support entitlement with OWS products |access-date= 16 December 2023}}</ref>
