In addition to the Server Unit, up to 20 autonomous high-end x86-64 servers, which are known as Application Units, can also be installed and operated in the rack of the 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 (two 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.
In comparison to guest systems on XenVMs in an SU x86, further operating systems can be operated on the Application Unit, and the selection of configured components is greater. The operating systems and the customer applications on the Application Unit run independently of the Server Unit.
The following operating systems can be used for Application Units:
SUSE Linux Enterprise Server 11 and 12 (SLES 11 and 12, 64-bit)
RedHat Enterprise Linux 6.5 and 7
Windows Server 2008 R2, 2012, 2012 R2 and 2016
VMware vSphere 5.1, 5.5, 6.0 and 6.5
Microsoft Windows Hyper-V Server 2008 R2 and higher
Citrix XenServer 6.5
Oracle LINUX 6.6 and 6.7
Oracle VM Server 3.3
If you want to use other operating systems or virtualization techniques, please contact 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 2 to 10 height units (HUs) in the rack, depending on the model. Up to 20 Application Units can be installed and operated in the rack or extension rack.
Depending on the hardware base, Application Units differ as follows:
Application Unit PY refers to all PRIMERGY based AUs (e.g. the AU20 or AU47 hardware models).
Application Unit PQ refers to all PRIMEQUEST based AUs (e.g. the AU87 or DBU87 hardware models).
