Novell Open Enterprise Server (OES) is the successor product to Novell, Inc.'s NetWare operating system, and is a NOS, or network operating system. Originally released in March 2005, the current release is OES 2.

[edit] Summary

OES is best thought of as a platform for delivery of enterprise-level shared network services (file, print, directory, clustering, backup, storage management, PKI, web applications, etc.) and common management tools. Unlike competing NOSes, OES can run atop either a Linux or a NetWare kernel. Clustered configurations can include nodes with either kernel types, and most services can migrate freely between the platforms. Thus, customers can deploy the platform selection that best suits their needs, as opposed to being locked into a single platform.

Licensing costs are identical regardless of the platform, and the platforms may be mixed under the same license. As is typical for Novell's products, OES is licensed per user seat, without regard to the number of physical servers on which the product is deployed. Further, pricing is typically not altered by physical CPUs or the use of hardware virtualization technologies (e.g. VMware, Xen). Finally, NetWare and OES both include 2-node licenses for Novell Cluster Services, allowing basic clustered environments to be created without additional licensing charges.

This contrasts directly with Windows, which imposes per-server charges, per-client charges, and levies additional charges for larger SMP support and even basic clustering.

[edit] OES-Linux

When installed using a Linux kernel, the product is known as OES-Linux. This uses SUSE Linux Enterprise Server (SLES) as its platform. Atop the SLES install, daemons are added to provide NCP, eDirectory, NSS, iPrint and other services delivered by OES.

[edit] OES-NetWare

When installed using a NetWare kernel, the product is known as OES-NetWare. This uses NetWare v6.5 as its platform. Atop the NetWare install, NLMs are added to provide NCP, eDirectory, NSS, iPrint and other services delivered by OES.

[edit] OES 2

OES 2 was released on October 8, 2007. It included NetWare 6.5 SP7, which supported running as a paravirtualized guest inside the Xen hypervisor and new Linux-based version using SLES 10. New features include:

• 64-bit support
• Virtualization
• Dynamic Storage Technology, which provide Novell Shadow Volumes
• Domain services for Microsoft Windows
