A FUJITSU Server BS2000 of the SE Series (SE server for short) can consist of the following components:
Management Unit (MU) with SE Manager
The operation of the SE server with a single Management Unit is called a "single-MU configuration". The Management Unit can be redundant in design. An SE server configuration with more than one Management Unit (MU redundancy on the SE server or Management Cluster with two SE servers) is called "multi-MU configuration". MU redundancy ensures that the components of the SE server can still be operated if one MU fails. In particular this means that the SKP functionality is then still available for operating an SU /390.Server Unit (SU)
An SU enables operation of BS2000 (Native BS2000 or VM2000). Depending on the model family, the following combinations are possible:SE server with an SU /390 and for SE700/SE500 optionally up to two further SU x86
SE server with an SU x86 and for SE300 optionally up to two further SU x86
Application Unit (AU)
Multiple AUs can be operated on the SE server. An AU enables operation of applications under Linux, Windows or hypervisor-based systems.
A distinction is made between AUs depending on the hardware base:Application Unit PY (AU PY) refers to all PRIMERGY-based AUs (e.g. hardware model AU25 or AU47).
Application Unit PQ (AU PQ) refers to all PRIMEQUEST-based AUs (e.g. hardware model AU87 or DBU87).
Net Unit (NU)
The Net Unit offers maximum performance and security for internal communication in an SE server and for a connection to customer networks (IP networks). For an SU /390, HNC is an additional component of the Net Unit.
In the case of SE server with an SU /390 the Net Unit is always redundant in design. In the case of SE server with SU x86 only redundancy of the Net Unit is optional.
The Net Unit is supplied preconfigured, is autonomous with respect to SE server management, and can easily be connected to the customer network.Rack console and KVM switch
Optional hardware components / peripherals integrated into the rack:
Disk storage systems (for SU x86, AU), tape library systems (for SU x86), FC switches
All components of the SE server are integrated into a joint rack or multiple racks. Information on the current hardware configuration of your SE server is displayed by the SE Manager in the Hardware -> HW inventory menu (see section "HW inventory").

The SE Manager enables you to operate and manage all components of the SE server centrally from the Management Unit. The SE Manager offers a user-friendly, web-based user interface for this purpose.
