High Availability

High availability is an all-encompassing term, and this term normally includes attributes such as
reliability and availability. If a system is under continuous operation, it is accessible 7 days a week and
24 hours per day by users and the system manager. Availability is designated in terms of 9s. For example,
the architecture of the SilkWorm 12000 is designed for availability in excess of 99.999%.
The following features contribute to the high availability design of the SilkWorm 12000:
•
Redundant, hot-swappable components
•
Redundant power and cooling subsystems
•
No single point of failure
•
Enhanced data integrity on all data paths
•
Fabric Shortest Path First (FSPF) automatic rerouting around failed links
•
Integration with SNMP managers
•
Automatic Control Processor fail over
