Novell Open Enterprise Server
Open Enterprise Server (OES) is a server operating system published by OpenText. It was first published by Novell in March 2005 to succeed their NetWare product. Unlike NetWare, OES is a Linux distribution—specifically, one based on SUSE Linux Enterprise Server. 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 (with a Linux compatibility layer). Novell discontinued the NetWare kernel prior to the release of OES 2, but NetWare 6.5 SP7, and later SP8, can run as a paravirtualized guest inside the Xen hypervisor (officially supported until 7 March 2012, Novell self-supported until 7 March 2015). OES 1 and OES 2 Novell released OES 1, the first version of OES, on 25 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 kerne ...

SUSE Linux Enterprise Server
SUSE Linux Enterprise (SLE) is a Linux-based operating system developed by SUSE. It is available in two editions, suffixed with Server (SLES) for servers and mainframes, and Desktop (SLED) for workstations and desktop computers. Its major versions are released at an interval of three–four years, while minor versions (called "Service Packs") are released about every 12 months. SUSE Linux Enterprise products receive more intense testing than the upstream openSUSE community product, with the intention that only mature, stable versions of the included components will make it through to the released enterprise product. It is developed from a common code base with other SUSE Linux Enterprise products. IBM's Watson was built on IBM's POWER7 systems using SLES. Hewlett Packard Enterprise's Frontier, world's first and fastest exascale supercomputer runs on SUSE's SLES 15 (HPE Cray OS). SUSE Linux Enterprise Server SLES was developed based on SUSE Linux by a small team led by M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IPrint
iPrint is a print server developed by Novell, now owned by Micro Focus. iPrint enabled users to install a device driver for a printer directly from a web browser, and to submit print jobs over a computer network. It could process print jobs routed through the internet using the Internet Printing Protocol (IPP). The iPrint server ran on Novell's NetWare operating system. Windows, Linux, and Mac OS clients needed Novell's iPrint client software to make use of iPrint services. Although iPrint is bound to Novell Distributed Print Services (NDPS), it does not require a Novell client but only an iPrint client.

Novell Storage Services
Novell Storage Services (NSS) is a file system used by the Novell NetWare network operating system. Support for NSS was introduced in 2004 to SUSE Linux via low-level network NCPFS protocol. It has some unique features that make it especially useful for setting up shared volumes on a file server in a local area network. NSS is a 64-bit journaling file system with a balanced tree algorithm for the directory structure. Its published specifications (as of NetWare 6.5) are: * Maximum file size: 8 EB * Maximum partition size: 8 EB * Maximum device size (Physical or Logical): 8 EB * Maximum pool size: 8 EB * Maximum volume size: 8 EB * Maximum files per volume: 8 trillion * Maximum mounted volumes per server: unlimited if all are NSS * Maximum open files per server: no practical limit * Maximum directory tree depth: limited only by client * Maximum volumes per partition: unlimited * Maximum extended attributes: no limit on number of attributes. * Maximum data streams: no limit ...

Novell EDirectory
eDirectory is an X.500-compatible directory service software product from NetIQ. Previously owned by Novell, the product has also been known as Novell Directory Services (NDS) and sometimes referred to as ''NetWare Directory Services''. NDS was initially released by Novell in 1993 for Netware 4, replacing the Netware bindery mechanism used in previous versions, for centrally managing access to resources on multiple servers and computers within a given network. eDirectory is a hierarchical, object oriented database used to represent certain assets in an organization in a logical tree, including organizations, organizational units, people, positions, servers, volumes, workstations, applications, printers, services, and groups to name just a few. Features eDirectory uses dynamic rights inheritance, which allows both global and specific access controls. Access rights to objects in the tree are determined at the time of the request and are determined by the rights assigned to the ...

NetWare Core Protocol
The NetWare Core Protocol (NCP) is a network protocol used in some products from Novell, Inc. It is usually associated with the client-server operating system Novell NetWare which originally supported primarily MS-DOS client stations, but later support for other platforms such as Microsoft Windows, the classic Mac OS, Linux, Windows NT, Mac OS X, and various flavors of Unix was added. The NCP is used to access file, print, directory, clock synchronization, messaging, remote command execution and other network service functions. It originally took advantage of an easy network configuration and small memory footprint of the IPX/SPX protocol stack. Since 1991 the TCP/IP implementation is available., page 6 Novell eDirectory uses NCP for synchronizing data changes between the servers in a directory service tree. Technical information The original IPX/SPX server implementation was provided only for Novell NetWare platform and now is obsolete. The TCP/IP implementation uses ...

NetWare Loadable Module
A NetWare Loadable Module (NLM) is a loadable kernel module (a binary code module) that can be loaded into Novell's NetWare operating system. NLMs can implement hardware drivers, server functions (e.g. clustering), applications (e.g. GroupWise), system libraries or utilities. NLMs were supported beginning with the Intel 80386-based NetWare version 3.x. Prior versions of NetWare had a monolithic kernel, and significant hardware or functionality changes required re-linking the kernel from object modules. Due to stability issues with early third-party NLMs, they never became popular for server application programming, with few exceptions like antivirus programs, backup programs and certain database products. Functionality Upon loading, a NLM requests resources, such as memory and process threads, from the NetWare kernel. The NetWare kernel tracks such requests, and can identify memory and other resources assigned to a specific NLM. NLMs may auto-load other NLMs upon which the ...

User Space
A modern computer operating system usually uses virtual memory to provide separate address spaces or regions of a single address space, called user space and kernel space. This separation primarily provides memory protection and hardware protection from malicious or errant software behaviour. Kernel space is strictly reserved for running a privileged operating system kernel, kernel extensions, and most device drivers. In contrast, user space is the memory area where application software and some drivers execute, typically with one address space per process. Overview The term user space (or userland) refers to all code that runs outside the operating system's kernel. User space usually refers to the various programs and libraries that the operating system uses to interact with the kernel: software that performs input/output, manipulates file system objects, application software, etc. Each user space process usually runs in its own virtual memory space, and, unless explici ...

Backward Compatibility
In telecommunications and computing, backward compatibility (or backwards compatibility) is a property of an operating system, software, real-world product, or technology that allows for interoperability with an older legacy system, or with Input/output, input designed for such a system. Modifying a system in a way that does not allow backward compatibility is sometimes called "wikt:breaking change, breaking" backward compatibility. Such breaking usually incurs various types of costs, such as Switching barriers, switching cost. A complementary concept is ''forward compatibility''; a design that is forward-compatible usually has a Technology roadmap, roadmap for compatibility with future standards and products. Usage In hardware A simple example of both backward and forward compatibility is the introduction of FM broadcasting, FM radio in stereophonic sound, stereo. FM radio was initially monaural, mono, with only one audio channel represented by one signal (electrical engineerin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypervisor
A hypervisor, also known as a virtual machine monitor (VMM) or virtualizer, is a type of computer software, firmware or hardware that creates and runs virtual machines. A computer on which a hypervisor runs one or more virtual machines is called a ''host machine'', and each virtual machine is called a ''guest machine''. The hypervisor presents the guest operating systems with a virtual operating platform and manages the execution of the guest operating systems. Unlike an emulator, the guest executes most instructions on the native hardware. Multiple instances of a variety of operating systems may share the virtualized hardware resources: for example, Linux, Windows, and macOS instances can all run on a single physical x86 machine. This contrasts with operating-system–level virtualization, where all instances (usually called ''containers'') must share a single kernel, though the guest operating systems can differ in user space, such as different Linux distributions with the sam ...

Hardware Virtualization
Hardware virtualization is the virtualization of computers as complete hardware platforms, certain logical abstractions of their componentry, or only the functionality required to run various operating systems. Virtualization emulates the hardware environment of its host architecture, allowing multiple OSes to run unmodified and in isolation. At its origins, the software that controlled virtualization was called a "control program", but the terms " hypervisor" or "virtual machine monitor" became preferred over time. Concept The term "virtualization" was coined in the 1960s to refer to a virtual machine (sometimes called "pseudo machine"), a term which itself dates from the experimental IBM M44/44X system. The creation and management of virtual machines has also been called "platform virtualization", or "server virtualization", more recently. Platform virtualization is performed on a given hardware platform by ''host'' software (a ''control program''), which creates a simulat ...

Paravirtualization
In computing, virtualization (abbreviated v12n) is a series of technologies that allows dividing of physical computing resources into a series of virtual machines, operating systems, processes or containers. Virtualization began in the 1960s with IBM CP/CMS. The control program CP provided each user with a simulated stand-alone System/360 computer. In hardware virtualization, the ''host machine'' is the machine that is used by the virtualization and the ''guest machine'' is the virtual machine. The words ''host'' and ''guest'' are used to distinguish the software that runs on the physical machine from the software that runs on the virtual machine. The software or firmware that creates a virtual machine on the host hardware is called a ''hypervisor'' or ''virtual machine monitor''. Hardware virtualization is not the same as hardware emulation. Hardware-assisted virtualization facilitates building a virtual machine monitor and allows guest OSes to be run in isolation. Desktop v ...
