Highly Available Computing for Synchronicity Products
This paper describes techniques and products
to help a Synchronicity installation achieve a Highly Available
(HA), fault resistant requirement. A fault resistant environment
expects that problems will occur and solutions are already in place
to act on the failure. Note: A fault resistant, highly available
computing environment should not be confused with a fault tolerant
environment. Fault tolerant systems have stringent uptime
requirements, have double and triple redundant systems and can
typically cost many millions of dollars. A fault resistant
environment does not try to continue normal operations through a
fault, but will try to recover from the vault as soon as possible
and resume normal operations.
