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 |
| day or more of |
| companies' business plans and recovering |
| required. |
| Maintenance |
| HP Remote Snap software can also be used to solve other business needs. For instance, |
| 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 |
| |
| 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. |
| |
| 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. |
