Customer Benefits Disaster Recovery
Replication technology has typically been used to address disaster recovery issues. Disaster
recovery is still the driving business case behind replication. Remote replication can be
implemented from the production site to one or more remote sites across a campus, across town,
across a state or across the country. When a disaster strikes the primary location, the applications
can be brought up at the remote site and continue processing against the replicated copies. When
the primary site is back online, the replication can be reversed and when the data is
resynchronized, processing can be switched back to the primary site and business can continue.
In the past, if an e-mail system experienced a disaster it was an "oh well" moment. The loss of a
day or more of e-mail was not considered important. Today, e-mail is a critical component of many
companies' business plans and recovering e-mail after a disaster quickly and completely is
required.
Maintenance
HP Remote Snap software can also be used to solve other business needs. For instance, E-mail
servers may need periodic maintenance that can take hours to complete. With remote replication
in place, the downtime can be minimal (as long as it takes to bring the remote peer of the primary
e-mail server online). The primary server can be worked on (patches, hardware upgrades, etc.)
and then brought back online and into production. A whole datacenter can be failed over to a
remote site on purpose to perform maintenance on generators, air conditioning, etc. Replication
can also be used to perform a datacenter move with minimal downtime (fail everything to the DR
site, move the production datacenter to its new location then fail the DR site back to the new
datacenter).
Storage Based
Data replication is performed at the storage subsystem controller level and is totally transparent to
the host, alleviating unnecessary host cycles to perform the data mirroring functions. Unlike a
fabric based or host based solution, the storage based solution dedicates its resources to
managing the replication process between arrays, with minimal impact to applications, other data
or devices on the SAN.
