The following sections summarize the coexistence and migration issues related to storage services.
The SUSE Linux Enterprise Server 15 (SLES 15) SP4 platform on which OES services are installed, includes two open source databases:
NOTE:Full OES support of these databases requires a product-specific Micro Focus support contract. Documentation and support are available through open source communities as outlined below.
The SLES 15 platform includes the open source MySQL database server and client. When combined with a Web application and a Web server, MySQL is a very reliable and scalable database for use in hosting e-commerce and business-to-business Web applications. See the documentation on the Web.
For overview of MySQL and for information about configuring it with Cluster Services, see Configuring MySQL with Novell Cluster Services
in the OES 2015 SP1: Web Services and Applications Guide.
The more powerful PostgreSQL database server also comes with SLES 15. See the PostgreSQL documentation on the Web.
OES provides support for Storage Services (NSS) as well as Linux POSIX file systems.
To support migration from NetWare to OES, NSS volumes are cross-compatible between NetWare and Linux.
On OES, you can use NSS volumes only as data volumes.
You configure NSS pools and volumes in iManager or NSSMU after the server installation completes successfully. You can also use the Linux Volume Manager (NLVM) command line interface.
Starting with NetWare 6.5 SP4 (and OES 1), a new metadata structure provided enhanced support for hard links. After you upgrade your operating system to OES, you must upgrade the media format in order to use the new metadata structure; some restrictions apply. For more information, see Upgrading the NSS Media Format
in the OES 2023: NSS File System Administration Guide for Linux.
For additional information about coexistence and migration of NSS volumes, as well as access control issues for NSS on Linux, see Cross-Platform Issues for NSS
in the OES 2023: NSS File System Administration Guide for Linux.
Both eDirectory and Active Directory are supported as identity sources, and OES enables the NSS file system to accept eDirectory and Active Directory identities as trustees. For more information, see Upgrading the NSS Media Format
in the OES 2023: NSS File System Administration Guide for Linux.
IMPORTANT:Users can access data storage on OES servers through a number of methods. For more information, see Overview of File Services.
OES includes tools and services that help bridge the gap between traditional OES file services and Linux POSIX file services.
Using NSSMU and the Linux Volume Manager (NLVM) command line interface, you can create native Linux POSIX volumes and standalone or clustered Linux Logical Volume Manager 2 (LVM2) volume groups and logical volumes.
OES includes NCP Server for Linux. After you create native Linux POSIX volumes, you can use NCP Server to create NCP shares on them. You can then manage the shares as NCP volumes.
This lets Client for Open Enterprise Server users map drives to Linux POSIX file system data, with access controls being enforced by NCP. For more information on using NCP Server for Linux in OES, see the OES 2023: NCP Server for Linux Administration Guide.
