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.

 

Bi-Directional

 

The bidirectional HP P2000 Array solution addresses the growing need among businesses to

 

ensure continuous availability of applications that are critical to daily business operations. HP

 

StorageWorks P2000 enables two sites in a remote replication connection to use each other as a

 

destination to maintain replicated copies of online data. This maximizes resource utilization while

 

enabling business continuance, even in the event of disaster.

 

Disaster Tolerance

 

The P2000 G3 FC products utilize snapshot data online and in real time to a remote P2000 G3

 

through a local or extended storage area network (SAN). Additionally, data replication can be

 

bidirectional, meaning that a storage array can be both a source and a destination. A particular

 

LUN can be replicated in only one direction between the two storage arrays. Write I/O data sent to

 

the source is replicated by HP P2000 Array to the destination. A pair of properly configured HP

 

P2000 G3 FC arrays is a replication solution that guarantees data integrity in the event of a

 

storage system or site failure.
