The High Availability (HA) feature refers to the awareness of component failure and the
availability of backup resources. The complexity of HA is determined by the availability needs
and the tolerance of system interruptions. Systems, that provides nearly full-time availability,
typically have redundant hardware and software that makes the system available despite
failures.
The high availability of the V3300 Series is designed to avoid single points-of-failure. When
failures occur, the failover process moves processing performed by the failed component (the
“Master”) to the backup component (the “Slave”). This process remains system-wide
resources, recovers partial of failed transactions, and restores the system to normal within a
matter of microseconds.
Take the following picture as an example. The left V3300 Series is regarded as Master device,
the right V3300 Series is regarded as Slave device. When Master V3300 Series is broken
down, the Slave device could replace the Master role to take over all jobs as soon as possible.
However, once the original Master is working again, the Slave would be changed to original
role to stand by.
