S2-PDGS-OLQC-100
The PDGS/OLQC function shall be able to perform simultaneous data processing
activities issued from distinct directives on the same hardware or on different hardware
without interference.
5.6.2 PERFORMANCE REQUIREMENTS
S2-PDGS-OLQC-105
The systematic operations of the PDGS/OLQC function shall impose less than a 5%
overhead over the processing resources required to complete the global systematic data
processing within identical timeliness constraints.
5.6.3 OPERATIONAL REQUIREMENTS
S2-PDGS-OLQC-110
The PDGS/OLQC function shall generate all quality control check PDIs according to the
directives of the DPC function.
S2-PDGS-OLQC-115
The PDGS/OLQC function shall perform autonomously without any operator intervention
once triggered.
S2-PDGS-OLQC-120
The PDGS/OLQC function shall supply status information over its processes and
resources (i.e. log information, disk volumes usage, alarms, etc.) in real-time via the M&C
function.
5.6.4 RAMS REQUIREMENTS
S2-PDGS-OLQC-125
The PDGS/OLQC function operations shall ensure nominal operations unattended for
better than 99.7% of the time computed over one month time window and assuming a
degradation of such figure for no more than one day.
5.6.5 DESIGN & DEVELOPMENT REQUIREMENTS
S2-PDGS-OLQC-130
The PDGS/OLQC function design shall allow the simultaneous execution of different
instances of the same task or different tasks on the same HW.
