Final assessment
Keeping a reserve of free resources in the form of an additional XSB enables the hardware
failure to be compensated for both in terms of the CPUs and the memory.
The most complex solution – provision of 100% capacity after a hardware failure – is thus
the best possible solution.

Important notes
– In this scenario the roles of XSBs 00-0 and 01-1 are swapped.
– XSB 01-3, which was originally kept in reserve, initially remains in the partition.
– The original boot-XSB 00-0 is initially not put into operation; it can take on the
role of the CoD-XSB.
– At the earliest when Solaris is rebooted can the initial status be restored.
– A return to the initial status as soon as possible is recommended as no
redundancy of the peripheral ports (ports in this status are only available via
XSB 01-0) is provided. Furthermore, only in the context of Solaris being
rebooted is it ensured that the planned memory is once more fully assigned to
BS2000.
