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.
