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 MSA 1040 Array solution addresses the growing need among businesses to ensure
continuous availability of applications that are critical to daily business operations. HP MSA 1040 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 1040 Arrays utilize snapshot data online and in real time to a remote MSA 1040 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 1040 Array to the
destination. A pair of properly configured HP MSA 1040 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 a initial copy of the data from the source volume to the target volume must
occur. The MSA 1040 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 1040 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
