Novell Open Enterprise Server (OES) is a server operating system published by Novell in March 2005 to succeed their NetWare product.
Contents
Unlike NetWare, Novell OES is a Linux distribution—specifically, one based on SUSE Linux Enterprise Server. The first two major releases of Open Enterprise Server could run either with a Linux kernel (with a NetWare compatibility layer) or Novell's NetWare kernel (with a Linux compatibility layer). Novell discontinued the NetWare kernel prior to the release of OES 11.
OES 1 and OES 2
Novell released OES 1, the first version of OES, in March 2005. 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 userlands.
OES-NetWare is NetWare v6.5 equipped with NetWare Loadable Modules 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).
OES-Linux is a variation of SUSE Linux Enterprise Server (SLES) with added NetWare services: the NetWare Core Protocol, Novell eDirectory, Novell Storage Services, and iPrint.
OES 2, released on 8 October 2007, retained the OES-NetWare option. Its operating system, NetWare 6.5 SP7, can run as a paravirtualized guest inside the Xen hypervisor. The OES-Linux edition was updated to SLES 10.
Features introduced in OES 2 include:
OES 11
OES 11 was released 13 December 2011 based on SLES 11 SP1 64-bit. This is the first version of OES to be 64-bit (x86_64) only, and to be SLES based only (not NetWare).
Novell released a service pack, OES 11 SP2, on January 28, 2014.
OES 2015
Novell released a service pack, OES 2015 SP1, in 2016.
Release summary
Components
Vendor motivation
Novell executives, as well as most analysts, expect that porting these services to an OS with growing popularity and better support from hardware and software vendors will give Novell a good opportunity to improve its business results.
OES is Novell's reaction to two things:
License costs
Licensing costs are identical regardless of the platform, and the platforms may be mixed under the same license. As with Novell's other products, OES is licensed per user seat, without regard to the number of servers. Pricing is typically not altered by physical CPUs or the use of hardware virtualization technologies (e.g. VMware, Xen). NetWare and OES both include two-node licenses for Novell Cluster Services, allowing basic clustered environments to be created without additional licensing charges.
In comparison, Microsoft Windows charges per server and per client, with additional charges for larger SMP support and for clustering.
