The Fujitsu Server BS2000 SE series with its innovative HW and SW features forms the proven mainframe line from Fujitsu. Designed as hybrid systems, the SE servers create a new quality of openness and integration capability of different server and peripheral systems with simultaneous comprehensive and cross-system manageability.
Under the umbrella of the SE infrastructure, multiple application scenarios are possible in various combinations for both mainframe applications and applications of the open world. The server architecture offers comprehensive performance scalability (scale-up and scale-out), and ensures that users can manage their application workloads securely, quickly and efficiently across technological boundaries with maximum availability.
One major aim of the SE servers is to provide a uniform management strategy which offers customers significant added value through maximum integration, and guarantees extremely cost-effective operation of their IT.
The heart of the SE series is formed by the /390-based Server Units, the x86-based Server Units, the Net Unit (NU) and the Management Unit (MU).
All components are integrated into a standard 19" rack and are supplied to customers ready to use.
In addition to their high system performance, the servers of the SE series offer enhanced configuration options, maximum availability and, not least of all, significantly reduced power consumption compared with predecessors.
Depending on requirements, the SE server contains all the system components needed for operation as an overall application:
Server Unit /390 for BS2000 guest systems
Server Unit x86 for BS2000 guest systems
Application Units x86 for operating Native or hypervisor systems (e.g. Linux, Windows, VMware, etc.)
- Net Unit as a high-speed, server-internal infrastructure to connect the components with each other and with the customer's IP networks.
Shareable tape and disk periphery
Infrastructure to connect the components with the customer's FC networks.
Main features of an SE server are:
Cross-system administration with state-of-the-art, browser-based GUI (SE Manager) as a single point of operation
Centralized system monitoring of all components
End-to-end redundancy concept
Joint service process for all units
Various options for consolidation through virtualization
SE components and infrastructure are preconfigured and supplied to customers ready to use.
Regarding customer's requirements, SE servers enable a flexible and application-specific implementation which fulfills high SLAs (Service Level Agreements) through the use of high-end components and an end-to-end redundancy concept. This permits cost-effective operation of the overall system with few resources thanks to its uniformity.
Intel x86-based Application Units with their systems also profit from the concepts for stable system operation tested on the mainframe:
Selection of high-quality server components
Redundant hardware components
Prepared operating concepts which also include high availability
High level of proven quality through extensive testing before release
Comprehensive service concept.
The uniform management interface, the SE Manager, permits a simultaneous view of all the system components of the SE servers involved and, from this higher-level perspective, enables the resources to be optimized through efficient distribution of the application to the systems which are currently utilized least.
It is possible to combine up to eight SE servers in a Management Cluster to one management entity and therefore utilize the advantages of the central administration with the SE Manager for several SE servers at the same time. Every Management Unit can be used to control all components of the cluster, thus enhancing protection against failure.
Two Server Units can be combined in an SU Cluster. Thus, live migration (LM) allows to relocate BS2000 systems between the units without interruption.
SE servers consequently permit very stable system operation which includes not only the mainframe platforms which have to date been known to be particularly failsafe, but also the other units and the infrastructure and peripherals employed by the SE server. This can be achieved with fewer resources for administration and system operation than for separate operation of different IT systems.
In this manual, abbreviations are used to describe the SE server models and their components. These are explained in the introduction to the Basic Operating Manual [1] in the section "Models, Names, Abbreviations".
