IOCF / IORSF
Contains information on the configuration of the input/output devices of an SU /390.
An IORSF contains a BS2000 device configuration, which is required to start up an SU /390.
The IOCF must be installed in the service processor SVP in order to be used.
IOGEN
BS2000 utility routine to generate an IORSF configuration (IOCF)
KVP
Console distribution program
Access to a BS2000 console window takes place via a KVP (console distribution program).
The KVP performs the following tasks, among others:
Authorization checks
Distribution of the BS2000 tasks to multiple console windows
Short- and long-term storage of the console communication logs (KVP logging)
BS2000 sees a KVP as two (emulated) KVP devices (or a device pair) which are identified by their mnemonic names.

Management Optional Network Public
MONPU
Public management network, which can be configured as the additive administration network when required (e.g. when AIS Connect is not to be operated via MANPU but over a separate network).
Management SVP Network Private
MSNPR
Private management network, which enables the SVP communication to the SU /390 on SE servers with SU /390.
Management Unit
MU
Component of the SE server; with the help of the SE Manager, enables central, web-based management of all units of an SE server.
Multi-factor authentication
MFA
Login procedure (at the SE Manager) in which the access authorization is checked by several (here: two) independent characteristics (factors).
Net-Storage
The storage space provided by a server in the computer network and released for use by foreign servers. Net-Storage can be a file system or also just a node in the Net-Storage server's file system.
Net-Storage client
Implements access to Net-Storage for the operating system using it.
In BS2000 the Net-Storage client, together with the BS2000 subsystem ONETSTOR, transforms the BS2000 file accesses to corresponding UNIX file accesses and executes these using NFS on the Net-Storage server.
Net-Storage server
File server in the worldwide computer network which provides storage space (Network Attached Storage, NAS) for use by other servers and offers corresponding file server services.
Net Unit

SENET
senet
A DNS server for the "senet" domain which provides name resolution for communication (especially for the internal communication within MCNPR) runs on every MU. The DNS server is configured in such a manner that it performs name resolutions for "senet" itself and forwards other name resolutions to external DNS servers which must be configured in addition.
Server line, Server type
SE /390, SE x86
- SE /390: A server of this line resp. of this type contains one SU /390 and optional one or several SU x86.
- SE x86: A server of this line resp. of this type contains one or several SU x86 and contains no SU /390.
Server Unit
SU
Component of the SE server that supports the operation of BS2000 (Native-BS2000 or VM2000). SU types are SU /390 and SU x86 - see below. The models and the abbreviations used for them can be found, for example, in the Basic Operating Manual [1].
Server Unit /390
SU /390
Component of the SE server; Server Unit with /390 architecture. A /390-based Server Unit (SU /390) enables operation of BS2000 (Native BS2000 or VM2000).
Server Unit x86
SU x86
Component of the SE server; Server Unit with x86 architecture. An x86-based Server Unit (SU x86) enables operation of BS2000 (Native BS2000 or VM2000).
Service and console processor
SKP
An SKP enables servers with /390 architecture to be operated, the connected devices to be managed, and remote service to be supported.
The term SKP is used in the three views hardware functionality, software functionality, and device type:
- Hardware functionality
To operate, S servers require an SKP as a hardware unit which has a local console, a Host Controller, and various ports for LAN connection and supporting remote service.
On the SE server the Management Unit (MU) provides this hardware functionality for operating SU /390. - Software functionality
On an SKP hardware unit the SKP Manager provides the SKP functionality for operating the S server and managing the devices and remote service.
On the SE server the SKP functionality is integrated into the SE Manager. - Device type
In BS2000 an SKP device type is used (e.g. SKP2).
SVP
Service processor of the SU /390.
With SU x86 there is an emulated SVP functionality in the X2000, as faras necessary.
SVP clock
Autonomous clock which supplies the TODR (Time of Day Register) with the real time at system startup. In SU /390 the SVP clock is part of the SVP. In SU x86 the SVP clock is emulated via the basic software X2000.
Unit x86
Component of the SE server with x86 architecture: Server Unit x86, Management Unit or HNC
