In addition to the Server Unit, up to 256 autonomous high-end x86 servers, which are known as Application Units, can also be installed and operated in the racks of an SE server.
Application Units are particularly suitable for important corporate applications. They offer a high degree of data security and availability through highly-developed hardware and software components. Their structure (one to eight Intel processors of the XEON family) and their scalability enable them to be employed for a large number of customer applications, e.g. for medium-sized or large databases, for ERP systems and for subapplications which interwork with a BS2000 application on the Server Unit.
Several operating systems can be run on an Application Unit and there is a wide range of configurable components. The operating systems and the customer applications on the Application Unit run independently of the Server Unit.
For example, the following operating systems and hypervisor systems (for virtualization) can be used on Application Units:
SUSE Linux Enterprise Server 12 and 15
Red Hat Enterprise Linux 7 and 8
- VMware vSphere® ESXi 7.0 and 8.0
The list of currently supported operating systems and hypervisor systems can be found in the Release Notice for M2000 available on the manual server (http://bs2manuals.ts.fujitsu.com). The use of operating systems or hypervisor systems depends on the series and model of the application unit. For further details or if you want to use other operating systems or virtualization techniques, please contact the Customer Support.
It is the responsibility of the customer to configure the Application Units, and also to installand operate his/her own software on the Application Units, see the “Operation and Administration” manual [5].
Application Units are integrated into the service concept of the SE server, e.g. into remote service via the MU and into administration with the SE Manager. The following functions are offered for Application Units in the SE Manager:
Status display of the Application Unit
Display and configuration of the links to the web interfaces of the applications on the Application Unit
Operation of the Application Unit and the AU VMs
Remote powering on of the Application Units using the iRMC
Integration into AIS Connect (remote service)
Storage Management functions via the add-on pack StorMan
Detailed information on this subject is provided in the "Operation and Administration" manual [5].
An Application Unit occupies 1 to 7 height units (HUs) in the rack, depending on the model. Up to 256 Application Units can be installed and operated in the rack or extension racks.
Depending on the hardware base, Application Units differ as follows:
Application Unit PY refers to all PRIMERGY based AUs (e.g. the AU25 or AU47 hardware models).
Application Unit PQ refers to all PRIMEQUEST based AUs (e.g. the AUQ38E or DBU38E hardware models).
