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 MSA 2040 Array solution addresses the growing need among businesses to
ensure continuous availability of applications that are critical to daily business operations. HP MSA
2040 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 MSA 2040 Arrays utilize snapshot data online and in real time to a remote MSA 2040 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 MSA 2040 Array to the destination. A pair of properly configured HP MSA 2040 arrays
is a replication solution that guarantees data integrity in the event of a storage system or site failure.
First initial copy
When a DR site is initially created an initial copy of the data from the source volume to the target
volume must occur. The MSA 2040 array allows this first copy to take place locally. After completion
the disks can me manually moved to the remote location. Subsequent changes will only remotely
copy the changed blocks.
SAN Extensions
HP MSA 2040 Array provides the capability to replicate data over direct Fibre Channel. The distances
supported over dark fiber are determined by the speed of the dark fiber connection and the
technology used to communicate over the dark fiber.
Path failover (MPIO)
Multipath failover (MPIO) is supported on all operating systems
