High Availability Design Principles
o
Intra-site replication solution for High
Availability for Servers and quick Disaster recovery options.
o
Eliminate single point of failure (redundant
configurations)
The
duplication of components to ensure that should a primary resource fail, a
secondary resources can take over its function
o
Guarantee 100% uptime
Implementation
intended to ensure a 100% of operational and business continuity
o
Fault tolerance
The
ability to continue properly when a hardware or software fault or failure
occurs. Designed for reliability by building multiples of critical components
like controllers, switches, connectivity, adapters, memory and disk drives.
o
DR Replication
provides
Storage Level Replication and able to recover the data as per the agreed
RPO/RTO
